Multi-Channel Ecommerce ERP Integration for Shopify and Amazon
Ecommerce ERP integration connects Shopify, Amazon and your wholesale channels to one system. Orders, stock, shipping and customer data stay in sync automatically, so nobody retypes an order and the books reconcile themselves.

The systems we connect to your ERP
Storefronts, marketplaces, payments, shipping and accounting, reading and writing one order record.
An order taken on any channel lands in stock, accounting and shipping without anyone retyping it. On Odoo, that is Odoo Inventory and Odoo Accounting working from the same order. We build on the ERP you already run, whether that is Odoo, NetSuite, Sage or Dynamics; where a tool has no native connector, we build one.

What Is Ecommerce ERP Integration?
Ecommerce ERP integration connects your storefronts and marketplaces to one operating system, so orders, stock, customers and money move without retyping. An order placed on Shopify or Amazon books its own stock move, invoice and shipment, the delivery is raised for the warehouse, the tracking number travels back to the channel, and the fee the marketplace kept is already an expense line waiting for its payout.
That one shared record is what fixes the two jobs that eat the week. A marketplace payout covering weeks of orders splits itself back into those orders, each fee posted to its own account and matched against the bank line, so reconciliation becomes checking rather than archaeology. And because every channel reads one stock position, the last unit sells once: a spike on Amazon lowers what Shopify can promise inside the sync window, not overnight.
A US security-hardware seller we work with sells its locks on BigCommerce, Amazon and Shopify. One stock figure serves all three channels, the marketplace fees land in their own account, nobody retypes an order, and the setup has since been upgraded from Odoo 16 to Odoo 19 without breaking the sync.
Ecommerce is one of the industries we serve. For connections beyond your sales channels, see our ERP integration services and Odoo integration services, and for Shopify on Odoo, our guide Odoo and Shopify: Accounting and Inventory in Sync.
How we connect each channel
Native connector
Where a maintained connector already exists for your channel and your ERP, we configure it and map products, prices, taxes and customers. It is the fastest route to run and the simplest to support.
Middleware
When several channels and systems need the same data, an integration platform moves it between them on a schedule or in real time. It suits a stack that changes often, at the cost of one more tool to pay for and watch.
Custom API
Where no connector fits, we build one on the channel’s API and webhooks, so the data moves exactly the way your operation needs. It takes longer to build, and on a support plan, fixing a connection we built is included if it ever stops working.
Business Challenges We Solve
One online order, followed from first click to closed books, and the problems it no longer causes.
Morning: The Order Lands Once
Amazon, Shopify and wholesale orders arrive in one queue. Nobody opens five back offices to find them.
Mid-Morning: Nothing Is Retyped
The order books itself: sales order, delivery, invoice, customer record. The hours lost to copy-paste go back into selling.
Noon: The Count Still Holds
Every sale already lowered the shared stock position. When the last unit sells on one channel, the others stop promising it.
Early Afternoon: A New Channel Joins
The next marketplace is a connector and a price list, not a new hire. You scale by adding channels, not headcount.
Late Afternoon: Picked, Packed, Gone
The delivery was raised the moment the order landed, so the picker never waited on an export. Tracking posts back on its own.
End of Day: Live Numbers, No Export
Dashboards show sales, stock and fulfillment as the day actually went, so tomorrow’s decisions use tonight’s numbers.

FROM THIS INDUSTRY
A security-hardware seller runs BigCommerce, Amazon and Shopify from one Odoo system.
Orders, stock and tax unified across channels, then upgraded from Odoo 16 to Odoo 19 without breaking the sync.
Read the case study →Five Tools Today. One System After.
This is the swap multi-channel sellers actually make: not another app in the stack, but replacing the pile that grew one channel at a time.
What the operation runs today
- Stock counted in a spreadsheet that is wrong by Friday
- Orders retyped from the marketplace into accounting
- A shipping app that never tells the store what shipped
- QuickBooks that has never heard of the Amazon fees
- Price changes made five times, in five back offices
What it becomes on one system
- One stock position, updated by every channel in real time
- Orders that book their own invoice, stock move and shipment
- Tracking that flows back to the channel and the customer
- Marketplace fees reconciled into the books automatically
- One price list, pushed everywhere it applies
Sellers rarely switch everything at once, and they should not. We move one channel at a time, prove it, then move the next. Read how our phased ERP migration works.
The Stack, Wired Into One Order Book
Multi-channel only works when every channel writes to the same record: storefronts, marketplaces, carriers, and the ledger. These are the connections we build most.
Storefronts
SalesShopify, BigCommerce and WooCommerce in real-time two-way sync: products, pricing and stock flow out, orders and customers flow back, and deliveries are raised the moment an order lands.
Every storefront sells from the same stock truth, and orders arrive ready to pick.
Amazon and Marketplaces
MarketplacesAmazon runs full order-to-cash in Odoo: orders, deliveries, invoices, payments, bank statements, credit notes, refunds, taxes and price lists, with salesperson and sales-team mapping, and every marketplace fee posted with its tax treatment attached.
Marketplace fees and tax are booked with each order, not left for month end.
Payments and Gateways
BillingGateway payouts reconcile back to the orders inside them, with fees split out to their own account instead of buried in revenue.
Payouts reconcile to orders, fees and all, with nothing matched by hand.
ShipStation and Carriers
FulfillmentShipStation labels, carrier rates and tracking numbers come off the order and post straight back, and partial shipments post honestly so a split order never reads as an unshipped one.
Labels, tracking and partials post themselves back to the order.
Accounting
FinanceRun the books in the same system, or keep QuickBooks connected while you decide. Either way sales, refunds and payouts land once, in the right period.
One set of books that agrees with what actually shipped.
Ad Platforms and Attribution
AttributionAd clicks carry through to the CRM record, so revenue ties to the campaign.
You see which ad made which order, in the same system that shipped it.
Got questions? We’ve got answers.
What is an ERP in ecommerce?
An ERP in ecommerce is the system behind the storefront that holds the products, stock, orders, customers and accounts for every channel you sell on. The storefront takes the order; the ERP books the stock move, the shipment, the invoice and the payout against it. Connected properly, every channel reads one record, so nothing is retyped and the books agree with what shipped.
Which sales channels can you connect to Odoo or your ERP?
Amazon, Shopify, WooCommerce and BigCommerce for selling, plus ShipStation for fulfillment, and most other marketplaces and storefronts on request. Where a maintained connector exists we configure it, and where none fits we build one on the channel’s API. Tell us your stack and we will say which route each channel takes.
Will my inventory stay in sync across every channel?
Yes. Stock updates in real time across all connected channels, so you avoid overselling and keep every storefront accurate. Every channel reserves against one stock position, so when the last unit sells on one channel, the others stop offering it. Stock can also be shown per warehouse, so each location sells from its own count.
Can you automate Amazon invoicing, taxes, and refunds in Odoo?
Yes. Amazon runs end-to-end: orders, invoices, payments, bank statements, credit notes, refunds, taxes, and price lists, all booked in Odoo. Each marketplace fee posts to its own account, and the payout splits back into the orders it covers. Reconciliation becomes checking, not re-entry.
Do you handle shipping labels and tracking?
Yes. Our ShipStation integration brings shipping labels and tracking numbers into Odoo, so every order is traceable from warehouse to doorstep. Tracking posts back to the channel and the customer, and partial shipments show as partial, not unshipped.
We sell on a platform that isn’t listed. Can you still help?
Very likely. Where a tool has no maintained connector, we build one on its API or webhooks, for marketplaces, storefronts, payment gateways and shipping managers alike. Tell us your stack and we’ll scope it.
How long does a multi-channel integration take?
It depends on how many channels you connect, the size of the catalog, how much order history moves across and how complex the finance side is. The scope, milestones and price are agreed in writing after a free demo, and we move one channel at a time. If we don’t deliver the scope and milestones we agreed in writing, you get your money back.
Why integrate ecommerce and ERP?
Because the gap between them is where money leaks: oversells, retyped orders, fees nobody reconciled, stock nobody trusts. Integration makes the storefront and the back office read one record, so orders, inventory and accounting agree without anyone copying data. The usual result is fewer errors and a team freed from keystrokes.
How do you connect an ecommerce platform with NetSuite ERP?
Through NetSuite’s connectors or middleware, and we build those when staying on NetSuite is right. The honest second question is cost: if NetSuite pricing is the reason you are asking, compare a migration before buying more integration. Our Odoo vs NetSuite comparison and our NetSuite to Odoo migration page cover both paths.
When to implement an ecommerce ERP solution?
When channel two arrives, or when the spreadsheet starts lying: oversells, unreconciled marketplace payouts, a stock count nobody believes. Implementing before peak season beats implementing during it. If you are already firefighting daily, a phased integration can start with the channel that leaks most.
How to choose an ecommerce ERP for Shopify, WooCommerce or Magento?
Choose on fit, not feature count: native connectors for your exact channels, one stock position across them, accounting that books fees and payouts, and pricing that survives your growth. Most of our work is on Odoo, and we also implement NetSuite, Sage and Microsoft Dynamics, so the recommendation follows your channels and your finance team rather than one product. We map your channels first, and when the system you already run is the right answer, we say so.
What does ecommerce ERP integration cost?
It depends on how many channels you connect, whether a maintained connector exists or one has to be built, and how much product and order history moves across. The scope and price are agreed in writing after a free demo. If you run Odoo, our support plans start at $250 a month once you are live; fixing a connection we built or support is included if it stops working, and adding a new connection is a separate project with its own quote.
Can B2B and wholesale orders run through the same system?
Yes. Wholesale orders land in the same order queue as Shopify and Amazon orders, with their own price lists, and draw on the same stock position. Where a retail buyer requires EDI, it is one of the connections we build. Our wholesaler case study shows a business that stopped retyping orders this way.
