Why accuracy matters more here

On Amazon, a slow sync is a performance problem, not a typo

Overselling on your own site means an apology email. On Amazon, cancelling orders you cannot fill or shipping late is tracked against your seller account.

That is why the integration has to be fast, accurate and built to fail loudly.

  1. 1

    Seller metrics are watched

    Amazon tracks seller performance such as cancellations and late shipments, and poor numbers can put selling privileges at risk.

  2. 2

    Stock must be right across channels

    A unit sold on Shopify has to come off Amazon, quickly, or one of them oversells.

  3. 3

    FBA and merchant stock are different

    Inventory in Amazon's warehouses is not the same pool as stock you ship yourself, and the integration must treat them separately.

  4. 4

    Listing data has to fit Amazon's catalog

    Identifiers, categories and attributes must match what Amazon expects, or listings get suppressed.

Four flows that have to run

Listings out, orders in, tracking back

Shopify catalog

Products and prices

Amazon listings

Matched or created

Amazon order

Into Shopify, ERP or WMS

Fulfillment

Ships from your stock

Tracking confirmed

Back to Amazon

We use Amazon's selling partner APIs, and orders can land in Shopify or go straight to your ERP or warehouse system.

What we handle

The parts that quietly cause problems

Listings and identifiers

Matching your products to existing Amazon listings, and creating new ones with the right attributes.

FBA vs merchant fulfilled

Separate stock pools and separate order paths, so neither one skews the other.

Pricing per channel

Amazon fees mean a different price may make sense there. Rules are set per channel, not copied.

Marketplace tax and fees

Amazon collects tax on many orders, so those orders must be flagged to avoid double tax and mismatched books.

Oversell buffers

A small hold-back on fast movers gives the sync time to catch up during spikes.

Rollout

How we bring Amazon online safely

  1. 1

    Connect and map

    Authorize your seller account and map your products and fulfillment methods.

  2. 2

    Match existing listings

    Attach what is already live instead of creating duplicates.

  3. 3

    Turn on inventory sync first

    Stock accuracy comes before order automation, tested in controlled batches.

  4. 4

    Add orders and tracking

    Then automate order import and shipment confirmation.

  5. 5

    Monitor closely

    Early watch on cancellations, delays and listing errors.

Frequently asked questions

Can you integrate Shopify with Amazon?

Yes. We sync listings, inventory, orders and tracking between Shopify and Amazon, and can route Amazon orders into Shopify, your ERP or your warehouse system.

Is a connector app enough?

For a small catalog with simple rules, a middleware-based connector can be the most cost-effective option. For larger catalogs, FBA and merchant mixes, or unusual pricing, a custom integration is usually more reliable. We recommend whichever fits your volume.

How do you prevent overselling?

We update stock fast, hold back a configurable buffer on fast-moving items, and keep FBA and merchant stock separate.

Does this cover FBA?

Yes. FBA stock is tracked separately from stock you ship yourself, and FBA orders are treated as fulfilled by Amazon, not routed to your warehouse.

Does it work with Shopify Plus?

Yes, standard Shopify and Shopify Plus.
