When do you outgrow spreadsheets?
A spreadsheet is enough while one person maintains it and the number of records is low. It starts costing you once more than one person edits the same file, once you can no longer tell whether a past record was changed, and once every balance has to be worked out by hand.

Side by side
| Spreadsheet | Pre-accounting software | |
|---|---|---|
| When a past record changes | No trace | Who, when, old and new value recorded |
| Account balance | Calculated by hand | Derived from movements |
| Several people at once | Risk of conflicts | Concurrent use, separated by permissions |
| Unique document numbers | Checked by hand | Enforced at the database level |
| Matching payments to invoices | Tracked manually | Recorded allocations, partial collections |
| Period close | None | Period lock |
| Up-front cost | None | Setup and migration work |
Signs the spreadsheet has stopped paying for itself
If three of these are true at once, it is costing you: month-end numbers do not add up and finding out why takes hours; you cannot answer “how much does this customer owe” without opening the file; two people edit the same document; you track which invoices were paid in a separate list; your accountant asks for missing documents every month.
The real problem is traceability, not speed
Typing over a cell leaves no trace. When the amount on an issued invoice changes, nobody notices, and the discrepancy that shows up at month end cannot be traced to a cause. What software actually changes is not how fast records go in; it is that a finalised record stops changing, and everything that does change leaves a trail.
What a migration involves
You do not need to bring the whole history. Customer and product lists import from CSV, opening balances go in as a single carry-over line, and everything after that date lives in the system. Open invoices are migrated separately so ageing works correctly. Keeping the spreadsheet in parallel for a while is a common and sensible approach.
Migration in this product
- Customer and product lists import from CSV
- We help with opening balances and carry-over records during setup
- An approved invoice cannot change; corrections are made by cancelling with a reason
- Every change is recorded as who–what–when, with the field’s old and new value
Where it does not fit
If you work alone, issue a handful of invoices a month and do not track stock, a spreadsheet is still a reasonable choice. Moving to software may create more work than it removes.
Frequently asked questions
Can I import my existing spreadsheets?
Customer and product lists can be converted to CSV and imported. Full invoice history is not imported directly; the usual approach is to start from opening balances and migrate open invoices separately.
How long does a migration take?
It depends on how much data you have. If the customer and product lists are ready the import is quick; preparing opening balances and open invoices is the part that takes time, and it is done together during setup.
Can I go back to spreadsheets if it does not work out?
Yes. Every list can be exported to CSV, so your data is not locked in. Running the spreadsheet in parallel during the transition is also common.
