Moving from Spreadsheets and Accounting Software to Manufacturing ERP

Answer

How do manufacturers move from spreadsheets to manufacturing ERP?

Migrate in thin vertical slices: one product family or one process (for example, sales-to-stock) rather than boiling the ocean. Keep the ledger of record until manufacturing documents post cleanly, then widen scope. FOS implementations follow discovery-to-hypercare stages described on /implementation and the SME ERP page.

Excel-to-ERP migration checklist

Use this as a practical cutover list. It is guidance for preparation — not a guaranteed timeline or customer outcome.

• Data preparation: clean item, customer, vendor masters; decide opening stock cut-off; map bins/stores
• Responsibilities: name BOM owner, inventory owner, finance owner and shift champions
• Validation: sample explode a BOM, issue to a work order, post a challan, invoice from dispatch qty in UAT
• Cutover: freeze the pilot spreadsheet slice on an agreed date; run thin vertical slice first
• Reconciliation: match stock, open WO and AR/AP bridges before widening scope; keep ledger of record until posts are trusted

What to migrate first: items, customers, vendors, open sales orders, on-hand stock and active work orders. Historical noise can wait.

What “done” looks like

Operators stop WhatsApping WIP counts for the pilot family. Purchase raises demand from MRP instead of a planner’s private sheet. Finance can trace an invoice to a dispatch quantity without retyping.

Example: An SME runs CRM and inventory for four weeks, then turns on planning and production for the same items once stock accuracy is trusted.
