B1
Migration guide
SAP Business One → ERPNext
SMB manufacturers running SAP Business One who’ve realized they’re paying enterprise prices for mid-market needs. The system works — but the cost, complexity, and consultant dependency don’t match the value.
Why teams move
Why manufacturers consider the switch
Cost
SAP B1 licensing plus SAP-certified consultants at $200+/hr for every change. For a 20-person manufacturer, the TCO adds up fast.
Complexity
SAP B1 inherits SAP’s DNA — powerful but over-engineered for most SMBs. Simple changes need consultant involvement.
Consultant dependency
Every workflow change, report, or integration needs a certified SAP partner — bottlenecks and cost.
Innovation pace
SAP B1 evolves slowly. The on-premise version (still common) is essentially in maintenance.
