Excel is not the enemy. It is flexible, everyone knows it, and it costs nothing extra. Plenty of profitable businesses run on it for years, and moving off it too early wastes money. The question is not whether spreadsheets are good — it is whether yours have quietly become the thing holding you back.
What Excel is genuinely good at
- Working something out for the first time, before you know the shape of it
- One-off analysis that will not be repeated
- A process only one person touches
- Anything you need to change faster than software can be changed
If that describes your use, stay where you are.
The six signs you have outgrown it
1. More than one person edits the same file
The moment two people need the same sheet, you get "final_v3_updated.xlsx" on WhatsApp and no certainty about which version is true. Shared cloud sheets help, but they do not stop two people overwriting each other’s logic.
2. The same data is entered twice
If a sale gets typed into a billing sheet and again into a stock sheet, the two will disagree — not if, when. Every manual re-entry is a place errors enter, and reconciling them is unpaid work.
3. Nobody can explain the formulas
When the person who built the workbook is the only one who understands it, that workbook is a risk. Businesses have lost months of reporting because one person left and took the logic with them.
4. Month-end takes days
If closing the month means collecting files from three people and reconciling them by hand, you are paying for that every single month. A system where the data was captured correctly the first time produces the report instantly.
5. You cannot answer simple questions quickly
"What did we sell last Tuesday?" "Which customers have not bought in six months?" "What is our margin on this product?" If these take an hour of digging, the data exists but is not usable.
6. There is no record of who changed what
Spreadsheets do not tell you who edited a number or when. Once staff are entering financial data, that becomes a control problem rather than an inconvenience.
What actually changes with an ERP
- Data is entered once and every part of the system uses the same copy
- Stock moves automatically when you bill, so it stays accurate
- Each person sees only what their role needs
- Reports come from live records, not from someone compiling files
- There is a log of who did what, and when
- Two people can work at the same time without conflict
The realistic downsides
It is worth being honest about the trade-off. A system is less flexible than a spreadsheet — a change that took two minutes in Excel may take a developer. There is a setup cost and a learning period where the team is slower before it is faster. And a badly chosen off-the-shelf ERP can be worse than the spreadsheets it replaced, because you end up bending your process to fit software written for someone else.
How to decide
Add up the hours your team spends each month on re-entry, reconciliation and report-building. Add what a stock error or a missed follow-up costs when it happens. If that total is meaningful against the cost of a system, the decision makes itself. If it is not, keep the spreadsheets and revisit in six months.
