Importing Amazon orders into SAP Business One: your options

August 18, 20265 min read

Amazon orders reach SAP Business One by one of four routes: exporting order reports from Seller Central and importing them into the ERP, a ready-made SP-API connector for SAP B1, an iPaaS platform, or an integration that pulls orders through the Amazon Selling Partner API (SP-API) and creates Sales Orders via the Service Layer or DI API, standalone or inside an integrated commerce platform. Which fits depends on order volume, fulfillment model (FBA or FBM), and how cleanly items, sales tax, and fees must land in the ERP.

01Starting point

Why do Amazon orders belong in the ERP?

A distributor selling through a B2B store and on Amazon has two order sources but one system of record. Inventory, accounting, and fulfillment meet in SAP Business One; until Amazon orders arrive there, someone re-keys them: slow, error-prone, unworkable at volume.

Then there is inventory. If the same SKU sells in your store and on the marketplace, B1 has to see both channels or one sells stock the other has committed. Automated import is the precondition for running Amazon cleanly beside your direct business, just as the store needs the platform’s ERP integration.

02The four options

How do Amazon orders get into SAP Business One?

All four have their place. They differ in effort, timeliness, and how much Amazon-specific logic (fees, sales tax, FBA inventory) they handle cleanly.

Approach Strengths Limits Typical use
Seller Central reports (CSV) Available today, no project; order reports load into B1 through the Data Transfer Workbench (DTW) Delayed and error-prone; SKU and tax mapping must be right every run; no status feedback to Amazon A few orders per week, marketplace trial
Ready-made SP-API connector for SAP B1 Proven standard from several vendors; order pull, Sales Order creation, and ship confirmation prebuilt License and maintenance fees; edge cases in tax, fees, or multi-warehouse logic need customization Standard Amazon operations with meaningful volume
iPaaS / middleware Amazon, store, and other channels on one platform; mapping maintained centrally Another system to run and pay for; one more link that can fail Multichannel landscapes: Amazon plus store, PIM, or 3PL
SP-API integration, custom or platform-integrated Full control over mapping, tax logic, and error handling; official interfaces on both sides (SP-API, Service Layer/DI API) Development project with ramp-up; operations and monitoring to plan High volume, own processes, requirements standard connectors do not cover

The same routes apply to your own store, compared in Connecting SAP Business One to an online store.

03The flow

How the order import actually runs

01

Pull orders

The integration polls the SP-API Orders API on a schedule. Import only once an order is Unshipped (payment confirmed); Pending orders lack reliable amounts.

02

Map SKUs

Every Amazon SKU maps to a B1 Item Code, most robustly via a maintained table (SKU/ASIN ↔ Item). Unmapped lines go to an exception queue, never silently dropped.

03

Decide on the Business Partner

Common practice: one collective Business Partner per marketplace (say, “Amazon.com”) with the ship-to per order. One BP per end customer bloats master data and pays off only for Amazon Business orders needing company invoices.

04

Create the Sales Order in SAP Business One

The Sales Order is posted via Service Layer or DI API with the Amazon order ID as customer reference (which also blocks duplicates), prices as sold including shipping, and the right tax treatment: in most states Amazon collects and remits sales tax as marketplace facilitator, and the tax code must mirror that.

05

Confirm shipment and status

For FBM orders, ship confirmation and tracking go back to Amazon once the Delivery is posted; late confirmations hurt seller metrics. For FBA, Amazon ships and the import serves accounting and inventory.

06

Reconcile settlements and fees separately

Amazon pays out in batches and deducts referral, FBA, and other fees first. Treat this as its own process: settlement reports are matched to the payout period’s orders and posted against fee accounts, or ERP revenue and bank deposits never reconcile.

04In practice

Where Amazon–B1 projects get stuck

Pulling orders is rarely the problem; the edges are. Four points to settle early:

FBA VS. FBM

Keep inventory in separate warehouses

Stock in Amazon fulfillment centers belongs in its own B1 warehouse, or your store sells units that sit with Amazon. Inbound FBA shipments are ordinary inventory transfers; FBM orders ship from your own warehouse.

SALES TAX

Mirror marketplace facilitator tax

Tax Amazon collects and remits must not appear as your liability, while direct-store orders still run through your own tax setup (Avalara, TaxJar, or B1 tax codes). After-the-fact corrections are the most expensive part of these projects.

ONE B1 COMPANY, TWO CHANNELS

Separate marketplace and B2B store orders

Amazon orders arrive with prices as sold; B2B store orders carry contract pricing from B1 Price Lists. Distinct Business Partners, a channel field or numbering series, and separate warehouses keep reporting and pricing from mixing.

RETURNS & OPERATIONS

Plan refunds, throttling, and monitoring

Amazon refunds generously, sometimes without a return; credit memos need the same automated path as orders. The SP-API throttles requests: the integration must retry, log, and alert before orders pile up.

05Where we fit

And what does this have to do with the CS Order Suite?

The CS Order Suite, our B2B e-commerce platform, connects your own store to SAP Business One through a native adapter: items, inventory, customer-specific prices, and orders move with no intermediate system. The building blocks an Amazon import needs (item mapping, Sales Order creation via Service Layer or DI API, status feedback) run in production there.

Honest fit check

We do not sell an off-the-shelf Amazon connector. If Amazon is your only channel into B1, a standard connector is the pragmatic choice. We fit when a B2B store and the marketplace are served from one B1 company and the import becomes part of an integration project.

06Frequently asked

Amazon and SAP Business One: short answers

Do FBA orders need to be imported into SAP Business One at all?

Yes, for revenue, inventory, and accounting: Amazon ships them, but the sale and the stock movement out of your FBA warehouse still have to be recorded. Only ship confirmation is skipped.

How do Amazon fees end up in SAP Business One?

Not through the order import. Fees are deducted before payout, so they are booked from the settlement reports as a separate step, matched to the orders of a payout period.

Can Amazon Business orders be treated like B2B customers?

They can be flagged and, if company invoicing matters, posted to their own Business Partners. Most sellers route them through the marketplace account and keep contract pricing for the direct B2B channel.
