Connect your Amazon channel to every system your business runs on
Fragmented channel data, manual order reconciliation, and disconnected fulfillment systems slow every Amazon brand that has grown past the basics. Amazon integration services replace the manual middle layer with a single connected system, so your Shopify, ERP, third-party logistics provider, and Amazon channel speak the same language automatically.

The operational cost of running Amazon as an isolated channel
- Inventory counts reconciled manually between Amazon, Shopify, and warehouse. Daily operations time spent on data that should move automatically.
- FBA restock decisions made on stale data. Overselling on Amazon while Shopify oversells the same stock keeping unit through a separate stock pool.
- Amazon order data lives in Seller Central while revenue reporting lives in an ERP. No single view of channel profitability or customer lifetime value.
- Catalog updates (prices, descriptions, variants) applied manually per platform. Amazon is always a version behind the source of truth.
- Inventory synchronized in real time across Amazon, Shopify, and warehouse. One stock pool, zero manual reconciliation.
- FBA replenishment triggered automatically from live sell-through data. Amazon never runs out while Shopify stock is sitting in a warehouse.
- Amazon orders, revenue, and returns flow directly into your ERP. One view of channel profitability without manual data transfer.
- Catalog updates pushed from a single source of truth to Amazon listings automatically. Price and content stay synchronized without manual uploads.

Every integration flows through Amazon's Selling Partner Application Programming Interface
The Selling Partner Application Programming Interface is Amazon's official data gateway for third-party systems. Every inventory sync, order import, catalog update, and fulfillment trigger uses authenticated endpoints. We build and maintain the application programming interface layer so you never interact with raw endpoints directly.
Amazon plus Shopify: one inventory pool, two channels
Shopify is the most common direct-to-consumer channel paired with Amazon. The integration syncs inventory in real time, imports Amazon orders into Shopify for unified fulfillment reporting, and pushes catalog updates from Shopify as the source of truth to Amazon listings. Amazon Multi-Channel Fulfillment can route Shopify orders through FBA stock.
Explore Shopify integration details →BigCommerce plus Amazon: catalog, inventory, and order sync
BigCommerce brands selling on Amazon need the same real-time inventory protection and order routing as Shopify brands. The integration syncs your BigCommerce product catalog to Amazon listings, keeps inventory unified, and routes Amazon orders into your fulfillment pipeline.
Explore BigCommerce integration →FBA fulfillment integrated with your inventory system
FBA stock levels are visible inside your other systems in real time. Replenishment alerts trigger automatically from sell-through rates. Amazon Multi-Channel Fulfillment routes direct-to-consumer orders through FBA stock, unified under one inventory pool across all your channels.
Explore FBA integration details →Amazon orders and revenue flowing directly into your ERP
Amazon order data, returns, and reimbursements are pushed directly into your ERP (NetSuite, NAV, Business Central, or custom) without manual data entry. One view of channel profit and loss, inventory cost, and customer data across Amazon and your primary systems.
Explore ERP integration options →Amazon Fulfilled by Merchant orders routed directly to your third-party logistics provider
Fulfilled by Merchant orders arrive in Amazon and route automatically to your third-party logistics or warehouse management system. Shipping confirmation and tracking data flows back to Amazon automatically, meeting service level agreement requirements without manual touch points.
Explore Fulfilled by Merchant integration details →Real-time inventory sync eliminates oversell risk
Inventory counts update across all connected systems within seconds of a sale on any channel. Amazon, Shopify, and your third-party logistics provider see the same stock number at all times. Oversell risk is eliminated without requiring your team to manually reconcile counts.
Amazon orders routed, confirmed, and reported automatically
Fulfilled by Merchant orders are pushed to your fulfillment system with all required data: buyer address, ASIN, quantity, and service level agreement deadline. Shipping confirmation loops back to Amazon automatically. FBA orders appear in your ERP for revenue and margin reporting without manual entry.
Your product catalog pushed to Amazon from a single source
Title, bullets, price, and variant data maintained in your primary system (Shopify, ERP, or product information management) sync to Amazon automatically. Price changes, new stock keeping units, and catalog corrections reach Amazon within minutes of the source update. No manual upload, no version lag.

Multi-channel integration that unified Amazon FBA and direct-to-consumer systems from launch
A funded direct-to-consumer health and wellness startup launched from zero to a multi-channel ecommerce operation with Amazon FBA, Shopify direct-to-consumer, and unified fulfillment as the foundation.
No Amazon presence, no direct-to-consumer storefront, no unified fulfillment strategy, and no lifecycle marketing system existed at launch. The integration challenge was building all systems simultaneously and connecting them from day one, not retrofitting integration into an already-fragmented stack.
Unified fulfillment via Amazon FBA and Multi-Channel Fulfillment for centralized inventory across Amazon and direct-to-consumer. One stock pool, two channels, zero manual reconciliation from launch day.

Amazon integration services questions answered
Connector tools map preset data fields between two platforms and break when either platform changes its application programming interface. Custom Amazon integration services build the data layer to your specific stack: your data model, your business logic, your ERP field names. When Amazon changes a Selling Partner Application Programming Interface endpoint (which happens regularly), we update the integration. You do not have to rebuild or switch tools.
We build integrations for Shopify, BigCommerce, WooCommerce, Magento (Adobe Commerce), NetSuite, Microsoft Dynamics NAV, Business Central, custom ERPs, third-party logistics providers, warehouse management systems, and marketplace expansion from Walmart and TikTok Shop. If your system has an application programming interface or data export capability, it can be integrated with Amazon's Selling Partner Application Programming Interface.
A standard Shopify to Amazon inventory sync and order routing integration takes 3 to 6 weeks from sign-off to go-live, depending on your data complexity and the number of connected systems. An ERP integration with custom field mapping and order routing logic takes 6 to 12 weeks. Your proposal includes a week-by-week delivery schedule with milestones and go-live date so you know exactly what to expect.
Amazon Multi-Channel Fulfillment allows your FBA inventory to fulfill orders from channels other than Amazon, including your Shopify direct-to-consumer store. The integration connects your direct-to-consumer checkout to the Multi-Channel Fulfillment application programming interface, so when a Shopify order is placed, it is automatically routed to Amazon FBA for picking, packing, and shipping. Your customer receives the same FBA delivery speed without you operating a separate warehouse for direct-to-consumer. We build the integration layer that makes Multi-Channel Fulfillment invisible to your team.
Yes. Amazon's Selling Partner Application Programming Interface updates endpoints, deprecates older application programming interface versions, and changes authentication requirements on a schedule. We monitor all connected integrations and push updates before deprecated endpoints cause failures. Ongoing maintenance is scoped as part of the original proposal. You receive notification of any Amazon-side changes and the timeline for the update before it affects your live integration.
Good fit and not a fit
We work best with brands that are operationally ready for a custom integration. Here is an honest read.
- Brands selling on Amazon who also run a Shopify, BigCommerce, or custom storefront and need them sharing one inventory pool.
- Operations teams spending more than 2 hours per day on manual reconciliation between Amazon and another system.
- Brands on ERP systems (NetSuite, NAV, Business Central) that need Amazon channel data flowing into financial reporting automatically.
- New Amazon sellers who want to build the integration correctly from launch rather than retrofit it later.
- You are pre-revenue and not yet selling on Amazon. A custom integration is not the right starting point.
- You only sell on Amazon and have no other system that needs to receive data. A standalone Seller Central account does not require a custom integration layer.
- You need a plug-and-play solution with no technical setup. Our builds are custom-coded, not drag-and-drop.
- You need the integration live within a week. A scoped custom build needs 3 to 6 weeks from sign-off to go-live.
