Warehouse Management System (WMS)

An open-source WMS platform optimized for cross-border e-commerce, handling inventory, fulfillment, returns, billing, and 3PL operations. Targets small-to-medium online sellers and fulfillment centers who need affordable inventory management.

Cross-border e-commerce volume has grown sharply since 2020 and shows no sign of contracting, but the software serving it — especially at the SMB and 3PL tier — remains fragmented, expensive, or both. ShipBob and Extensiv (formerly 3PL Central) dominate the mid-market, but neither is open-source or priced for a founder running one or two warehouse locations. The $5k–$30k/mo revenue band is plausible only if the monetization model leans on hosted/managed tiers, support contracts, or per-shipment fees rather than expecting SMBs to pay large SaaS seats — open-source alone won't get you there. The single most likely failure mode is the sheer operational surface area: WMS software touches physical workflows, carrier integrations, customs logic, billing reconciliation, and real-time inventory state simultaneously, meaning the support burden alone can kill a two-person team before they reach meaningful MRR.
