A spreadsheet is the right tool for tracking expenses — right up until it isn’t. The honest answer to “should I use Excel or an app” is it depends on your volume and whether anyone else needs access.
When a spreadsheet is genuinely fine
If you have fewer than about ten transactions a month and you’re the only person who touches the numbers, a spreadsheet is free, flexible, and good enough. Don’t let anyone upsell you off it. You can sort, total, and chart everything you need.
The four signs you’ve outgrown it
- Manual entry is eating hours. Past ~10 transactions a month, typing each line (and cleaning bank exports by hand) starts costing 2–3 hours monthly.
- You’re missing deductions. Spreadsheets don’t remind you. The $240 course in March gets forgotten by tax time because nothing flagged it.
- You need a budget that warns you. A spreadsheet shows what you spent. It won’t alert you at 80% of a category limit before you overspend.
- Someone else needs in. The moment a partner, accountant, or teammate needs access, a shared spreadsheet becomes a permissions-and-version nightmare with no audit trail.
What you gain — and what you give up
Moving to Money OS gets you CSV import (no manual typing), category budgets with alerts, multi-client tagging, role-based team access, and an audit trail of every change.
What you give up is total formula flexibility. A spreadsheet can model anything; an app makes deliberate choices about structure. If your tracking depends on custom formulas no tool would anticipate, a spreadsheet may still win.
The honest recommendation
- Stay on a spreadsheet if you’re solo, low-volume, and value total flexibility over automation.
- Move to Money OS when manual entry is costing real time, you want budget alerts, or more than one person needs access — and you’d rather not pay for it.
Either way, your data is portable: export the spreadsheet as CSV and it imports in minutes if you decide to switch.
