Excel or ERP — when it’s time to switch

Excel is a great tool. The problem isn’t Excel — it’s when a whole company runs on spreadsheets only one person understands. Here’s how to tell when it’s time for more.

Five signs you’ve outgrown Excel

1. The same data is entered several times — in a sheet, in the invoicing software and on paper.
2. There are “versions” — final, final2, final-real.
3. Stock doesn’t match reality, and every count brings surprises.
4. One person makes the reports and they take days.
5. Several people must work at once — and the file locks or overwrites someone’s work.

When Excel is perfectly fine

If you’re a small company, one or two people enter data and there’s a single site, Excel is fast and free. Don’t replace something that works just because “everyone has an ERP”.

What an ERP actually changes

• One database — data is entered once and everyone sees the same thing.
• Roles — everyone sees and edits only their part.
• History — you know who changed what and when.
• Real-time reports, without stitching sheets together by hand.

How to switch without chaos

1. Describe processes as they are, not as they “should” be.
2. Clean up the master data: items, customers, prices.
3. Start with one module — usually the warehouse or sales.
4. Run in parallel for a short time, then retire the spreadsheet.

You don’t need an off-the-shelf ERP full of modules you won’t use. A custom system can grow with you. More about custom ERP →
