1What SyncEcom does

If you sell on Shopify and on Amazon, you normally do every job twice. Add a product twice. Change a price twice. Watch stock in two places and hope they agree. They stop agreeing, and you sell something you no longer have.

SyncEcom joins the two. It does four things.

• It puts your Shopify products on Amazon. You choose a product, answer Amazon's questions about it once, and publish. Amazon gets a product page and your offer.
• It brings your Amazon listings into Shopify. If you already sell on Amazon, those listings can be copied across so both sides hold the same catalogue.
• It keeps stock level. When stock changes in Shopify, Amazon is told. When something sells on Amazon, Shopify's stock comes down. You do not do this.
• It brings Amazon orders into Shopify. The order arrives in your Shopify admin, you pack it there as usual, and the tracking number goes back to Amazon on its own.

Shopify is always the source of truth. Your stock, your prices and your product details live in Shopify. SyncEcom reads them and tells Amazon. It does not keep a second copy of your catalogue that you have to maintain.

SyncEcom never changes something on Amazon without you asking. Nothing is published, and no price is sent, until you say so.

2Words you will meet

Amazon has its own vocabulary. These five come up constantly.

Listing

The product page on Amazon — photos, title, description, features. Amazon keeps one page per product, shared by everyone who sells it.

Offer

Your promise to supply that product, at your price, from your stock. Your offer sits on the listing.

ASIN

Amazon's code for a product page. Ten letters and numbers, like B0FWZWY9KJ. It is the part of an Amazon web address after /dp/.

SKU

Your own code for a product, set in Shopify. It is how SyncEcom knows which Amazon listing belongs to which Shopify product.

GTIN, UPC, EAN

The barcode number. Amazon uses it to tell your product apart from every other product in the world. In Shopify this is the Barcode field on a variant.

FBA

Amazon holds your stock in its warehouse and ships it for you. When a listing is FBA, Amazon owns the stock number, so SyncEcom never sends one.

The listing and offer split matters more than it sounds. Amazon can hold a perfect product page with no offer attached, and then nothing is for sale however much stock you sent. Seller Central calls this “Missing Offer”. SyncEcom tells you when it happens.

3Getting started

What you need first

• A Shopify store.
• An Amazon Professional seller account. Amazon's system refuses Individual accounts, so this is not optional.
• Products in Shopify with a SKU on each variant, and ideally a barcode and a photo. Amazon refuses listings without these, and SyncEcom says so rather than letting you find out from Amazon.

Opening the app

SyncEcom runs on its own website, syncecom.kayease.com, not inside the Shopify admin. Installing it from Shopify takes you there. The first time, you create your SyncEcom account — your name, an email of your choosing, and a password. After that you sign in with that email and password, either from the Log in button on the front page or by opening SyncEcom from the Apps list in your Shopify admin.

Each store has its own account, and an email can belong to only one of them, so a second store needs a different email. Password boxes have an eye you can press to see what you have typed. Sign out is at the foot of the sidebar, under the store's name and the person signed in.

The setup card

When you open the app for the first time, Home is a setup card. There are no dashboards or numbers yet, because there would be nothing in them.

The card is headed Set up SyncEcom and has two steps: Shopify connected, which installing the app already did, and Connect Amazon, which is your job.

Open the Amazon step and you will see exactly what connecting asks Amazon to allow — product and listing access, inventory, pricing, orders, and marketplace information. Beside the Connect Amazon button is an Amazon country dropdown, set to your store's country; change it if you sell somewhere else, and check the currency shown next to it. Press Connect Amazon and Amazon's own authorisation page for that country opens; approve it there and you come back to Home with the result.

The card ticks itself off as things finish. When both steps are done a Done button appears. You can also close the card at any time with the X in its corner; anything already running keeps running.

4Home

WhereSidebar›Home

Once setup is finished, Home answers one question: does anything need me right now?

The connection strip

Your Shopify store and your Amazon account side by side, with the time of the last sync. If something is wrong with a connection, it says so here first.

The what-to-do-next card

One tinted card, one sentence, one button, picking the single most useful thing for you to do. You will see things like:

• Connect Amazon when you are ready — nothing is connected yet.
• Sign in to Amazon again — your authorisation expired or was revoked. Nothing syncs until you fix it.
• Set what 1 INR is worth in USD — your store and Amazon use different currencies and no conversion rate is set. No price can be sent until there is.
• Bring your Shopify products in — your catalogue has not been read yet.
• 12 products cannot go live yet — they have problems Amazon would reject.
• Some listings need your decision — Amazon listings that look like products you already have.
• 3 updates did not get through — something failed on the way to Amazon.
• Nothing needs you right now — with a count of what is live and how many orders have come in.

Your store at a glance

Recent activity and Sync status

Two cards at the foot. Recent activity is the last few things the app did. Sync status shows the three scheduled jobs — send price and stock to Amazon, pull Amazon orders into Shopify, and re-check everything — with when each last ran and a plain verdict beside it. Only a row saying something could not be sent needs you.

5Connecting Amazon

Amazon has to authorise SyncEcom before anything can sync. This is that, once.

WhereSidebar›Home›Connect Amazon

Connecting happens on Home, in the Connect Amazon step of the setup card. Every Connect Amazon button elsewhere in the app brings you to that step.

Connecting

1. Choose your country in the Amazon country dropdown beside the button. It starts on your store's country, and the list shows the currency too, so you can check it is the marketplace you actually sell in.
2. Press Connect Amazon. Amazon's consent screen opens in place. Amazon asks for your password again even if you are already signed in — that is Amazon's rule for authorising any app, not a fault.
3. Sign in and approve.
4. You are returned to Home, where a green banner confirms which seller account is connected.

Twenty-one countries are supported: United States, Canada, Mexico, Brazil, India, United Kingdom, Germany, France, Italy, Spain, Netherlands, Sweden, Poland, Belgium, Turkey, United Arab Emirates, Saudi Arabia, Egypt, Japan, Australia and Singapore. Each region needs its own authorisation, though one European approval covers the European marketplaces.

Once connected

Check the connection

Asks Amazon, right now, whether the authorisation still works. Use this first whenever something looks wrong.

Change account

Re-authorises, and is also how you fix an expired authorisation. Your products, category choices and history are all kept.

Disconnect

Stops syncing. Nothing is deleted — reconnect the same country later and you pick up where you left off.

Currency

If your Shopify store and your Amazon marketplace use different currencies, you must set a conversion rate. Until you do, no price is sent to Amazon at all.

This is deliberate. A product priced at 24.99 in your store would otherwise be listed at 24.99 in Amazon's currency, which could be a fraction of what you meant to charge. You set the rate yourself under Settings, Price sync. SyncEcom never fetches or changes a rate on your behalf, because a rate that moves on its own moves your prices on its own.

6Bringing Amazon listings in

For merchants who already sell on Amazon: copy those listings into Shopify without creating duplicates.

WhereSidebar›Amazon›Import from Amazon

Skip this section if you have never sold on Amazon before — go straight to section 8.

Reading your Amazon listings

Press Import from Amazon. A dialog asks three questions:

1. Matching products — if an Amazon listing has the same SKU as a Shopify product, link them (recommended) or keep them separate.
2. Listings to import — active listings (recommended), all listings, or specific SKUs you type in.
3. Imported prices — shows the currency conversion that will be applied, so you see it before anything moves.

Under Advanced options you can also include drafts, include inactive listings, and include products Amazon stores and ships. That last one is off by default, because Amazon owns the stock number on those. Search depth offers a complete search, which takes about a minute and is the only way to be sure, or a quick search that takes seconds but never returns drafts.

Importing only reads Amazon. Nothing reaches Shopify until you choose it in the next step.

Deciding what belongs in Shopify

The table is headed On Amazon, and the right-hand column tells you where each listing stands:

Tick the rows you want and a bar appears at the foot of the screen. Send to Shopify asks whether to save them as drafts, which is recommended, or publish them straight away. Set aside leaves them on Amazon but stops offering them here. Remove from list clears the rows without changing anything on either side.

Drafts are recommended because a product arriving from Amazon carries Amazon's wording and photographs, and you may want to read it before your customers do.

Possible matches

When SyncEcom is not sure whether an Amazon listing is a product you already have, it does not guess. The row opens to show the Shopify product it suspects, why it suspects it, and two answers: Same product, link them, or Different product, import it. Getting this wrong in the linking direction is hard to undo, which is why you are asked.

7Products

Your whole Shopify catalogue, with what Amazon thinks of each product and one button per row telling you the next move.

WhereSidebar›Products

Four numbers sit at the top — total products, listed, needs attention, and Amazon only — and each is a link that filters the table below.

Finding a product

The search box matches titles and SKUs. Filter products opens a drawer with marketplace status, Shopify status, category, vendor, stock, whether there is an image and whether there is a barcode. Everything you choose goes into the web address, so a view can be bookmarked or sent to someone.

The table

Each row shows the product, where it came from, its Shopify status, price and stock, and then the two columns that matter: Amazon, which carries a status chip and a short reason, and Next step, which is one button that takes you exactly where you need to go — Set up for Amazon, Continue Amazon setup, Review Amazon setup, or Review Amazon listing.

Buttons at the top

Sync Shopify products

Re-reads your Shopify catalogue. Use it if you have just added products and they are not showing.

Refresh from Amazon

Asks Amazon about every listing and updates the rows with what it says.

Taking something off sale

WhereProducts›the row's ⋯ menu›Stop selling

In any row's menu, Stop selling takes the product off Amazon without destroying anything. Stock goes to zero, but the listing, its ASIN, its reviews and its search ranking are all kept. Start selling again puts it back with your current stock.

This is the right way to pause a product. Deleting the listing in Seller Central loses the reviews and the ranking permanently.

8Putting a product on Amazon

The main flow in the app, and the one worth reading once in full.

WhereProducts›any product›Set up for Amazon

Press Set up for Amazon on any product. Everything you type is saved as you go, so you can leave and come back.

Step 1 — Choose path

The first question changes everything else: does this product already have an Amazon page?

• Match an existing Amazon product — somebody already sells this exact product, so the page exists and you are adding your offer to it.
• Create a new Amazon listing — nobody sells it, so Amazon needs a whole new product page built from your information.

The two need completely different information, which is why it is asked first. Nothing is sent to Amazon by either choice.

Step 2 — Identify the product (creating a new page)

Choose the Amazon category. Amazon's category decides which questions it asks you, so it has to come first. SyncEcom suggests up to four based on your Shopify product type. If none fit, search Amazon's categories by name — try “water bottle” rather than “drinkware”.

Then the product identifier. Amazon asks for a UPC, EAN or GTIN to tell your product apart from everything else. There are three answers: yes it has one, which can be the barcode already in Shopify or a number you type here; no because Amazon has already approved a GTIN exemption; or not yet, which is allowed but means Amazon will refuse to publish.

SyncEcom checks the number's shape and its check digit before accepting it, so a mistyped barcode is caught here rather than by Amazon three steps later.

If the product has several variants you are also asked how they should appear on Amazon: a separate page for each variant, each with its own address and reviews, or one page with a selector where buyers pick colour or size. Choose carefully — this cannot be changed after publishing, and grouping pages later is a support request Amazon rarely grants.

Step 2 — Find on Amazon (matching an existing page)

Paste the ASIN if you know it, or search Amazon by ASIN, UPC, EAN, GTIN, your Amazon seller SKU, or plain keywords. Every result shows Amazon's own photo, title, variant label, ASIN, brand and product type.

Check the photo. Within one product family the ASINs differ by two characters and the titles are identical, so the picture is the only reliable way to catch a wrong match. A wrong match is not undone by an error message.

If your product has several variants, each needs its own ASIN — Amazon allows one offer per page. Results that look like a completely different product are marked and cannot be selected.

Step 3 — Complete details

Amazon wants a set of fields for your chosen category, sorted into four groups:

Required

Amazon will not publish without these. Anything SyncEcom could read from Shopify is already filled in.

Conditional

Only asked when they apply. Amazon asks whether the product contains batteries first, and the battery questions appear only if you say yes. Leaving these alone does not block you.

Already filled

What came from Shopify, and where each value came from. You can override any of them for Amazon without changing Shopify.

All Amazon fields

A reference table of everything this category defines.

Safety declarations are never filled in for you. Questions about hazards, batteries, country of origin and choking risks are things you are answerable for, so nothing is suggested. Answer them from the product's own paperwork, not to clear the box.

If your product has no photo, a drop zone appears here. The photo goes to your Shopify product, not into SyncEcom. You can continue with fields still empty — the Still to fill line keeps the list visible, and Publish is what actually holds you back.

Step 4 — Configure offer

Your offer is read-only: SKU, price and quantity, all from Shopify. They are not editable here because there is only ever one answer and it lives in Shopify. They stay in step automatically after publishing.

Offer details are optional extras Amazon accepts: condition and a condition note, who ships it, the number of items in a package, the item package quantity, and your Seller Central shipping template if you use one.

Step 5 — Review

When you arrive, SyncEcom asks Amazon to check the listing without publishing it. This is a practice run: Amazon reads everything and says what it would refuse. Nothing is created.

• Amazon needs these first lists anything blocking, with the fields editable right there. Fix them and press Save and re-check — it re-runs by itself.
• Before you publish lists warnings that will not stop you. Some carry a Fix this button, some say Open in Shopify because the answer lives there, and some have no button because nothing in this app can change them.
• What will be sent is the full summary: catalogue entry, your offer, your images and every listing detail, with where each value came from.

Publish to Amazon is only enabled when the check passed and nothing has changed since. If you edit something after a clean check, the check goes stale and you run it again — which is the app refusing to send something it has not verified.

Step 6 — Publish

This page reads Amazon live and tells you what Amazon actually holds, not what was sent. It shows one of: live on Amazon; ready but the offer has not attached yet, which usually settles within the hour; still processing, which for a new product page is normally minutes but can be up to 48 hours; waiting for Amazon's first answer; action required, with the exact thing to fix; or refused, with Amazon's own words and a Fix this button.

Below that is a list of checks covering the catalogue entry, offer, price, inventory, condition, fulfilment, main image and validation. Anything failing carries a button that lands on the exact field.

Nothing here is guessed. SyncEcom never marks a listing live because a request succeeded — only because Amazon later confirmed it.

9Inventory

What Shopify holds, against what Amazon shows — and why the two differ on purpose.

WhereSidebar›Inventory

How stock actually flows

Shopify is the source of truth. Quantities only ever travel from Shopify to Amazon. Amazon's number is read for comparison and never copied into Shopify. The one exception is a sale: when something sells on Amazon, that sale reduces your Shopify stock, because otherwise you would keep offering units you no longer have.

When stock changes in Shopify, Amazon is told within about ten seconds. If you bulk-edit a hundred products the updates collapse into one, so Amazon is not flooded. On top of that a scheduled catch-up re-sends everything, hourly by default.

Stock and orders ignore quiet hours. An oversell at three in the morning is worse than a change made at three in the morning.

After each update, SyncEcom checks about a minute later that Amazon really took it. Until that check lands, the row reads Sync pending.

The safety margin

WhereSettings›Inventory sync›How much stock Amazon sees

Out of the box, Amazon is shown two fewer units than you actually have.

This is the oversell guard. A sale on Amazon takes a few minutes to reach Shopify; if you had exactly one unit left, someone could buy it on both sides in that gap. Holding two back closes the window. You can change it under Settings, Inventory sync. The number never goes below zero — one unit in Shopify with a buffer of two sends zero, not minus one.

The table

When Amazon's number differs, a second line says by how much. Sync now on any row re-sends that variant, several rows can be ticked for a bulk send, and Sync inventory now at the top re-sends everything. View details opens the full picture for one variant, including every stock update, when it went, and whether it was sent, skipped, failed or is still queued.

Things that do not sync, and why

Amazon holds stock

An FBA listing. Amazon owns that number, so SyncEcom never sends one — sending one would create a second offer rather than overwriting, which is worse than doing nothing. Price still syncs.

Not listed

The variant has no live Amazon listing.

Sync disabled

Automatic sync is off and Amazon has never confirmed a quantity, so there is nothing to compare.

Never syncs

Set deliberately on one product, on that product's own page. This beats even a manual Sync now.

10Orders

Amazon sales, in the admin you already use.

WhereSidebar›Orders

Every order from every channel, in one list.

Needs you is deliberately narrow. An order is in it only if the import failed, or one of its lines matched no product in Shopify. Everything else is normal business.

Each order carries SyncEcom's own number, like SE-1019, which never changes; the channel's own status; Amazon's order number, which is the one to quote to Amazon support; and the total exactly as Amazon reported it, never recalculated.

What an Amazon order looks like in Shopify

If you have turned on order creation under Settings, Order sync, each Amazon sale becomes a Shopify order that is tagged SyncEcom and Amazon, marked paid because Amazon already took the money, carrying Amazon's tax figures as they were given, deducting stock, and not emailing your customer — Amazon has already done that.

A line whose SKU matches nothing in Shopify still imports, as a custom line. The order is never blocked, but no stock comes off for that line and the app says so clearly.

Fulfilling

WhereShopify admin›the order›Fulfil with a tracking number

Orders you ship yourself. Fulfil them in Shopify as you normally would, with a tracking number. The moment you do, SyncEcom sends the carrier and tracking number to Amazon. Amazon measures how quickly this arrives, so it happens immediately rather than on a schedule.

A long list of carriers is recognised, including BlueDart, Delhivery, DTDC, Ecom Express, XpressBees, Shadowfax, Ekart and India Post alongside the international ones. An unrecognised carrier is sent as “Other” with the real name attached rather than being refused, because a refused confirmation counts against you as a late shipment.

No tracking number means nothing is sent. A fulfilment without one is not something Amazon can use.

Orders Amazon ships. Nothing is needed from you. When Amazon reports it shipped, the Shopify order is closed automatically so it does not sit open for ever. Cancellations and refunds on Amazon flow the same way: the Shopify order is cancelled with stock restored, or a refund is recorded.

The order page

Open any order for the full story: the items and whether each matched a Shopify product, the money, the buyer, the fulfilment, and an activity panel that walks through what happened in order — placed on Amazon, products matched, order created in Shopify, stock deducted, packed and fulfilled by you, tracking sent to Amazon.

There is no payment status on an Amazon order, deliberately. Amazon collects the money and settles with you separately, so there is nothing here to show.

When Amazon withholds the buyer

Amazon shares buyer names and delivery addresses only with apps it has approved for customer data. When it withholds them you will see Delivery address is on Amazon — open the order in Seller Central to see it and post the parcel as usual. Everything else works normally, and once Amazon reports it shipped the order closes here and in Shopify on its own.

11Activity

WhereSidebar›Activity

Everything the app has done to your shop, newest first, and what set it off.

One action is one row, however many products it touched. Listing 400 products reads as a single line, not 400. You can search by product, SKU or wording, and filter to problems only or completed successfully.

Open any row for the individual products and a reference code. Quote that code if you contact support — it is the fastest way for someone to find exactly what happened.

How long activity is kept depends on your plan: 7 days on Free, 30 on Growth, 90 on Pro.

12Settings

Five tabs. Everything below says which one a control lives on.

General

WhereSidebar›Settings›General

Schedule — how often the three regular jobs run. Stock changes are sent the moment they happen regardless; these are the catch-up runs on top.

Each can be set to never, every 15 minutes, hourly, every 6 hours, or daily.

Quiet hours — on by default, midnight to 6am in your store's timezone. Scheduled runs wait. Price, stock and orders ignore it, for the reason above.

Email me if syncing breaks — one email, and only when things are genuinely broken: more than one sync in twenty failing, or nothing syncing for six hours. Never a single hiccup, and never more than once every few hours for the same problem. It goes to your Shopify contact email unless you type another address. This is the only email the app sends.

Marketplaces

WhereSidebar›Settings›Marketplaces

Amazon listing setup — answers used for every new listing so you are not asked each time: importer contact information, which is required on Indian listings and shown to buyers; country of origin; condition; who ships it; and your shipping template. Any of them can still be overridden on a single product.

Product details asks one question — who writes the product page? Shopify decides means your wording and photographs go to Amazon. Amazon decides means Amazon keeps its own. A listing this app created owns its Amazon page, so your content reaches it. A listing you joined to an existing page shares that page with other sellers, so Amazon decides whether your content may replace what is there. The Content check link shows what Amazon said for each one.

Automatic product sync brings new Amazon listings into Shopify on a schedule. It is off by default. When on, you choose how often, whether new products arrive as drafts (recommended) or published, and a ceiling per run. Anything that might be a duplicate is never created automatically — it waits for your decision on the Amazon page.

Price sync

WhereSidebar›Settings›Price sync

Keep prices in sync with Amazon is on by default. Price source offers three answers: SyncEcom pricing, which is your Shopify price with your formula applied; sync Shopify price, which sends it exactly as it is; or let Amazon manage the price, where Amazon's price is copied into Shopify and nothing goes the other way.

Price calculation is off by default, meaning your Shopify price goes unchanged. Amazon takes a commission, so the same price earns less there; this is how you charge differently without editing every product.

The formula reads as one sentence: start from your Shopify price, compare-at price or cost, then increase or decrease by an amount, as a percentage or a fixed sum. Then rounding — leave as is, or round to .99, .95, .90, .50, or a whole number — and limits: never below, never above, and a minimum margin percentage. Blank means no limit.

Try a price runs the real engine in your browser, so you can see exactly what would be sent before committing.

Currency conversion appears only when your store and marketplace currencies differ. It is one equation: 1 of your currency equals however many of theirs. Until it is set, no price is sent. The rate is yours, the app never changes it, and it warns you when a rate is more than 30 days old.

Inventory sync

WhereSidebar›Settings›Inventory sync

Automatic sync is on by default. Off means differences are still shown but nothing is corrected.

A separate maximum to send caps it; blank means no cap. A worked example updates as you change things, so you can see what Amazon would be shown.

Order sync

WhereSidebar›Settings›Order sync

Create Amazon orders in Shopify is off by default. Writing orders into a live Shopify account is not something an app should start doing unasked. Turn it on when you want Amazon sales to appear in your Shopify admin for fulfilment and reporting. Even with it off, inventory sync still keeps your Shopify stock correct.

Send the buyer's name and address to Shopify is on by default and only shown when the above is on. Turning it off keeps personal data out of Shopify; the buyer's details still appear on the order's page inside SyncEcom.

13Plans and limits

WhereSidebar›Plan

Every plan has the same features. What a paid plan adds is room.

What happens when you hit a limit

The next operation is refused, and it says exactly why — which limit, how much you have used, and what the next plan allows.

Nothing you already have is ever removed, unlisted, or un-synced. Products stay live, stock keeps syncing, orders keep arriving. You simply cannot add more. The same is true if you move down a plan.

Billing

All billing is handled by Shopify. App charges appear on your Shopify bill rather than as a separate invoice. See plans opens Shopify's pricing page and brings you back. Moving up is prorated, so you pay the difference for what is left of the month and the new limits apply as soon as you approve.

Cancelling stops the charge and leaves everything in place. Uninstalling is different — that starts a 48-hour clock on deleting your data.

14Status words, explained

Every coloured word the app shows you, and what it is telling you.

On the Products page

Listed

Live on Amazon. Buyers can buy it.

Listed — out of stock

The page is live but your quantity is zero. Add stock in Shopify.

Listed — offer on its way

Amazon is attaching your offer. Nothing to fix.

Publishing

Amazon is still processing it.

Suppressed

Amazon has it and is not showing it to buyers.

Removed from Amazon

The listing no longer exists on Amazon. Your setup here is untouched.

Needs attention

Amazon refused something. The reason is beside it.

Not for sale

You pressed Stop selling. The listing is kept.

Setup in progress

Started but not finished.

Setup required

Not started.

On the Inventory page

In sync

Amazon's number matches what it should be.

Out of sync

Amazon confirmed a different number.

Sync failed

The last update was rejected.

Sync pending

Sent; waiting for Amazon to confirm.

Sync disabled

Automatic sync is off for Amazon.

Amazon holds stock

FBA. Price syncs, quantity never does.

Not listed

No live Amazon listing for this variant.

On the Orders page

Synced

In Shopify, and every line came off your stock.

Stock not deducted

In Shopify, but nothing matched a product there. You are still offering what you sold.

Stock partly deducted

Some lines matched, some did not.

Not in Shopify

The sale happened and your store does not know.

Kept here

Order creation is off, so it stayed in SyncEcom. Stock still came down.

Waiting

Not brought across yet. The next check will take it.

15When something looks wrong

The things that go wrong most, and where each is actually fixed.

A product will not publish

Open it and go to Review. Amazon's own complaints are listed there, in Amazon's words, with the fields editable in place. The most common ones:

Amazon shows less stock than Shopify

Almost always your safety margin. Two units are held back by default. Check Settings, Inventory sync.

A price is not reaching Amazon

Three usual causes: no currency conversion rate is set and your store and Amazon use different currencies, so nothing is sent; price sync is switched off, or the price source is set to let Amazon manage the price; or a minimum margin or price limit is blocking it, and the price sync status card names which. Amazon can also take up to an hour to display a price it has accepted.

I edited the product in Shopify and Amazon has not changed

Stock goes within about ten seconds. Prices and other details go on the schedule, hourly by default. Use Send prices now or Sync inventory now if you do not want to wait.

Nothing is syncing at all

Go to Marketplace accounts and press Check the connection. An expired or revoked authorisation is the most common cause, and Change account fixes it without losing anything.

Amazon says processing — is my product live?

Not yet. Amazon builds a new product page in its own time, usually minutes, sometimes up to 48 hours. The Publish step reads Amazon live, so it tells you the moment that changes.

16Your data

The full notice is on the privacy page. In short:

SyncEcom does not sell, rent or share your data. No advertising, no analytics provider, no tracking.

What is stored

Your products, prices, stock and orders; your Amazon listings and orders; and your own contact details from Shopify so we can reach you.

Buyer details

Name, email and delivery address, where Amazon provides them. Encrypted, never written to logs, and erased automatically 30 days after the order was placed. The order and its financial record are kept.

Credentials

The tokens that let the app reach Shopify and Amazon are encrypted, never displayed, and deleted when you disconnect.

Servers

Mumbai, India.

The 30-day erasure has a practical consequence: after that, an order's customer panel is blank. If you need the address to ship, ship inside the window or read it from Seller Central.

Uninstalling the app starts deletion automatically. Write to support@kayease.com if you would rather not wait, or want a copy of what is held.
