Selling on Amazon while running SAP Business One means two views of the same stock and two sources of truth for revenue, unless the marketplace is wired into the ERP. A SAP Business One Amazon Seller Central integration pulls FBA and FBM orders into SAP B1 as sales orders, keeps Amazon listings in step with SAP stock, and brings settlement reports back so finance can reconcile fees and payouts. We build it on the Amazon Selling Partner API and the SAP B1 Service Layer or DI API, with the marketplace-specific edge cases (multi-marketplace accounts, FBA inventory held by Amazon, returns and reimbursements) handled explicitly.
Outcomes
Amazon SP-API is largely pull-based and rate-limited, so orders are typically polled every few minutes and inventory feeds are sent in batches. Settlement reports arrive on Amazon's payout cycle, usually every two weeks, and are processed as they appear. Where SP-API notifications are available we use them to cut latency.
We build a SKU-to-ASIN mapping table that your team can maintain, and unmapped items are flagged rather than guessed. Orders carry the Amazon order ID as a unique reference so a re-poll never creates a duplicate. Feed rejections and Service Layer errors are logged with the reason and retried or escalated.
Yes. We can build an MCP server that exposes both systems with scoped tools, so an assistant can check stock cover for a fast-moving ASIN, explain a settlement variance, or prepare a replenishment shipment plan for a human to approve. Write actions are limited to what you authorise.
Orders, FBM inventory, shipment confirmations and basic settlement posting usually take a few weeks, including SP-API app approval time which Amazon controls. FBA inventory reconciliation, multi-marketplace tax handling and full fee-level settlement mapping extend that and are scoped separately.
