SAP B1 ↔ Walmart WFS — Inventory + Fee Reconciliation
The SAP Business One ↔ Walmart Fulfillment Services (WFS) connector by ERPPlugs tracks inventory across every WFS warehouse as distinct SAP B1 warehouses, reconciles WFS inbound shipment receipts (with adjustments for damaged / lost / mislabeled units), posts storage + pick-pack + prep fees to distinct GL accounts per fee type, and handles cross-border WFS-to-customer shipments with correct destination-state tax. Adds the fulfillment-side accounting Walmart Marketplace connector alone misses.
Track WFS inventory as distinct SAP B1 warehouses; reconcile inbound receipts, fees, and cross-border shipments with correct destination-state tax.
What this connector does
Walmart Fulfillment Services (WFS) is Walmart's answer to Amazon FBA — sellers ship inventory to WFS warehouses, Walmart handles pick, pack, and delivery. WFS is growing 40%+ YoY and increasingly the fulfillment path for sellers on Walmart Marketplace who want two-day delivery on the Walmart+ badge. But the fulfillment side of WFS has its own accounting complexity: inbound shipments arrive with adjustments (some units damaged in transit, some mislabeled, some lost between sender and WFS receipt), Walmart charges storage fees monthly based on cubic footage, pick-pack fees per unit, and various prep fees (relabel, polybagging). None of this is captured in the standard Walmart Marketplace order feed.
The ERPPlugs SAP B1 ↔ WFS connector wires the Walmart Fulfillment Services API into SAP B1 to add the fulfillment-side layer. Every WFS warehouse (there are 100+ across the US) that holds your inventory becomes a distinct SAP B1 warehouse — so real-time inventory availability by fulfillment centre is directly readable from SAP B1 reports. Inbound shipments create Goods Receipt POs in SAP B1 when you ship to WFS; on WFS-side receipt, the connector reconciles actual received quantity vs expected (Walmart reports discrepancies via the API) and adjusts SAP B1 inventory accordingly with a Journal Entry to Inventory Adjustment GL for the loss.
Fees post cleanly. WFS charges monthly storage fees per cubic foot (calculated from average storage across the month), pick-pack fees per unit shipped, and various prep fees (relabel, polybagging, damaged item disposal). The ERPPlugs connector posts each fee type to a distinct GL account so per-fee-type reporting is directly readable — a common finance question ("what did we spend on WFS storage last quarter?") becomes a single SAP B1 report.
Cross-border shipments — WFS ships from a warehouse in one state to a customer in another — carry destination-state sales tax that WFS collects via its Marketplace Facilitator obligations. The connector integrates with your existing tax engine (Avalara / TaxJar) to record the destination-state tax correctly on each Sales Order, and reconciles Walmart's per-state tax remittance so your books match Walmart's Marketplace Facilitator filings exactly.

Frequently Asked Questions
Walmart Marketplace connectors (sap-b1-walmart) handle the order-side flow — Sales Orders, invoices, settlements. WFS is the fulfillment-side flow — inventory placement, inbound receipts, storage fees, pick-pack fees. Sellers using both Walmart Marketplace + WFS need both connectors; the ERPPlugs WFS connector is the fulfillment layer that sits underneath the Marketplace connector.
When you ship 1,000 units to WFS and they receive 985 (15 damaged in transit), Walmart's API reports the discrepancy. The ERPPlugs connector automatically posts a Journal Entry in SAP B1 reducing inventory by 15 units and debiting an Inventory Adjustment GL (typically tagged Damage-In-Transit). This lets finance track total inbound loss to WFS as a P&L line, which is important for warehouse-selection decisions and for filing insurance claims with the carrier.
Walmart charges monthly storage fees based on the average cubic footage stored across the month. The ERPPlugs connector reads the fee from Walmart's monthly billing report and posts it to a WFS Storage Fees GL account. If you want per-SKU visibility (which SKUs are eating the storage budget), the connector's optional detail-mode allocates the storage fee across SKUs based on their cubic-foot contribution — expensive on a compute basis but useful for slow-mover culling decisions.
Yes. Walmart, as a Marketplace Facilitator in most US states, collects sales tax on your behalf and remits directly to states. The ERPPlugs connector reads Walmart's per-state remittance report and posts it as a debit to Sales Tax Collected + credit to Sales Tax Payable on the SAP B1 side, then clears the payable when Walmart's remittance shows on your bank feed. Your books match Walmart's Marketplace Facilitator filings to the cent.
When a customer returns a WFS-fulfilled order, WFS either restocks the item to the WFS warehouse (if sellable), returns it to your warehouse for inspection (if damaged / questionable), or disposes of it (if unsellable). The ERPPlugs connector handles all three outcomes — restock updates WFS warehouse inventory, return-to-seller creates an inbound transfer to your seller-facing warehouse, disposal posts to Inventory Disposal GL with the loss.
