Enterprise Resource Planning
Enterprise resource planning (ERP) is business software that manages core company records such as finance, purchasing, inventory valuation, and sales orders in one system, often acting as the system of record.
Why it matters for ecommerce brands
As brands grow, the ERP usually becomes the source of truth for inventory value and purchase orders, while the WMS and OMS run daily operations. Integration gaps between them cause inventory and accounting mismatches.
Common questions
- Do I need an ERP or an OMS?
- An OMS routes and manages customer orders across channels, while an ERP handles finance, purchasing, and company-wide records. Many smaller brands start with an OMS plus accounting software and add an ERP as complexity grows.
