Chapter 01 · The Brief

Three marketplaces,
no single source of truth.

The business sold across Amazon, Kaufland and OnBuy, in several countries and currencies. Each marketplace had its own dashboard. Stock lived in one place, shipping in another, and supplier payments, payroll and settlement reports in yet more tools. Nothing reconciled without someone stitching exports together.

The brief: replace the patchwork with one control plane. Every order, every SKU, every payout and every employee in a single platform, with consistent data, shared workflows and a full audit trail.

Stock and dispatch,
in one place.

Stock is tracked per SKU across warehouses, FBA inbound shipments are followed all the way to Amazon, and SKUs map to listings on every marketplace. Merchant-fulfilled orders are batched into dispatch jobs with carrier labels through Evri.

Money in,
money out.

Settlement reports are reconciled against expected payouts and rolled into one P&L covering revenue, marketplace fees, shipping and net profit. Supplier payments and approved salaries go out through WISE, in batches and in any currency.
