SAP Business One + Amazon Integration
Connect Amazon Seller Central to SAP Business One so orders, inventory, and settlements move automatically between your marketplace and your ERP — no manual downloads, no spreadsheet reconciliation, no overselling.
What Does This Integration Do?
An Amazon seller account and SAP Business One naturally drift apart: Amazon holds the order and buyer data, B1 holds stock, cost, and financials. Without a sync, someone is downloading order reports and re-typing them into B1, or updating Amazon stock counts by hand every morning. That gap is where oversells, missed refunds, and late fulfillment come from.
This integration pulls new Amazon orders into B1 as sales orders or A/R invoices, pushes B1 stock levels back to Amazon so listings never oversell, and reconciles Amazon settlement reports — fees, refunds, reimbursements — against B1 incoming payments, so finance closes the books without a spreadsheet.
What Syncs, and Which Way
Most Amazon + B1 projects sync the same core objects. We adjust field mappings and frequency to match your fulfillment model and marketplace mix.
Orders
Amazon → SAP B1
New orders, buyer details, shipping address, order status
Inventory & Pricing
SAP B1 → Amazon
Stock levels, per-marketplace buffers, price updates
Fulfillment
SAP B1 → Amazon
Ship confirmation, carrier & tracking number, FBM shipments
Settlements
Amazon → SAP B1
Payouts, referral fees, FBA fees, refunds, reimbursements
Returns
Amazon → SAP B1
Return authorizations, credit memos, restock quantities
Multi-Marketplace
Amazon US / UK / AU / more
One B1 stock figure allocated across regional listings
How We Build It
Amazon's Selling Partner API (SP-API) is the modern, OAuth-based interface that replaced the older MWS API. We pair it with the same SAP B1 APIs used across our other integrations.
| Approach | What it is | Best for | Watch out for |
|---|---|---|---|
| Amazon SP-API | REST API for orders, inventory feeds, pricing, reports | Real-time order pull, scheduled inventory push | Rate limits per endpoint; report-based data has processing delay |
| SAP B1 Service Layer | REST/OData API for B1 business objects | Creating orders, invoices, and stock updates in B1 | Requires development skill; HANA-first |
| Settlement report parsing | Scheduled ingestion of Amazon financial reports | Fee & payout reconciliation against B1 payments | Report formats vary by marketplace and change periodically |
| iPaaS connectors | Pre-built templates (Celigo, CedCommerce, Codisto) | Standard order & inventory sync, going live fast | Subscription cost forever; settlement logic often needs custom work anyway |
Where a template usually falls short: most iPaaS connectors handle orders and inventory well but treat settlement reconciliation as an afterthought. If matching fees and payouts to the cent matters to your finance team, budget for a custom piece here even if the rest runs on a connector.
How Much Does It Cost?
A SAP Business One + Amazon integration typically costs between $3,000 and $18,000 to implement, depending on marketplace count and whether settlement reconciliation is included.
| Approach | Implementation | Ongoing |
|---|---|---|
| Templated connector (orders & inventory only) | $3,000 – $7,000 | $99 – $400/month platform subscription |
| Connector + custom settlement reconciliation | $6,000 – $12,000 | $100 – $400/month + support retainer |
| Fully custom SP-API build, multi-marketplace | $10,000 – $18,000+ | Support retainer only, no platform fee |
The number moves most on marketplace count, whether you fulfill FBA, FBM, or both, and whether settlement reconciliation is in scope. We quote a fixed price after a scoping call, so you know the cost before we write a line of configuration.
How Long Does It Take?
Amazon marketplace and category approvals sometimes run in parallel with development — we flag any of those early so they don't push your go-live date.
Templated integrations
Orders and inventory sync on a pre-built connector, single marketplace.
Custom builds
Multi-marketplace SP-API work with settlement reconciliation and FBA/FBM logic.
What Does Our Integration Process Look Like?
Every engagement follows the same five stages — you get a fixed-price scope and a mapping sheet you sign off before we build.
Discover
We map your marketplaces, fulfillment model, and the business outcome you need.
Map
We document every field, direction, transformation, and error rule before building.
Build
We implement against a B1 test company and Amazon's sandbox environment.
Test
We run real order and settlement scenarios end to end, including refunds and reimbursements.
Support
We monitor after go-live, with alerting, logging, and a named contact.
Frequently Asked Questions
We build against the Amazon Selling Partner API (SP-API), which replaced the older MWS API. It covers orders, inventory feeds, pricing, and settlement reports across Amazon marketplaces.
Yes. Fulfilled-by-Amazon and fulfilled-by-merchant orders carry different fulfillment and inventory logic, and we map each to the correct SAP B1 warehouse and document flow.
Yes. Settlement data — fees, refunds, reimbursements, and payouts — can be reconciled against SAP B1 incoming payments so finance isn't matching it manually.
Yes. A single SAP B1 stock level can push to several Amazon marketplaces (e.g. US, UK, AU) with per-marketplace buffers so you don't oversell.
Most projects run $3,000 to $18,000 depending on marketplace count, order volume, and whether settlement reconciliation is included. See the cost table above for a full breakdown.
Yes. A large share of our work is rescuing integrations that hit SP-API rate limits, drop orders, or fall out of sync after an Amazon API migration.

Every day without a sync is another manual stock update and another spreadsheet reconciling Amazon fees. A scoped integration removes that work permanently — and you'll know the exact cost before we start.
