Excel is bursting at the seams: when it’s time for a small ERP
Signs your spreadsheet has outgrown the business — and why a small ERP solves stock, invoices and VAT without SAP-level complexity.
Excel is great until the company grows. Then the problems start: two versions of the same sheet, stock that doesn’t match the warehouse, the invoice in one file and VAT in another. If this sounds familiar, your spreadsheet has burst.
Signs you’ve outgrown the spreadsheet
- Stock in Excel doesn’t match the real count
- You make the invoice in one program, stock in another, then retype
- You can’t reliably tell which item carries the margin
- Several people edit the same sheet and nobody knows which one is correct
Five scattered tools — or one NarBiz.
What a small ERP changes
A small ERP ties stock, invoicing, ledgers and VAT into one flow. When you confirm a document, stock and money post themselves — Excel and the warehouse stop drifting apart. And no, it doesn’t have to be as complex as SAP: Magaza is built so an ordinary person understands it.
Key takeaways
- Double entry and stock mismatches are a sign it’s time for an ERP
- Confirming a document = automatic posting of goods and money
- A small ERP ≠ SAP — it can be simple
