What spreadsheets do well
Be honest about the strengths first. Spreadsheets are unbeatable for one person analyzing data, for prototypes, for one-off calculations and for small lists that change rarely. If one or two people use the file and mistakes are cheap, keep the spreadsheet. Building software to replace it would be waste.
Eight signs you have outgrown spreadsheets
- Version conflicts. “Final_v3_JM.xlsx” exists, or people overwrite each other in a shared sheet.
- No permissions. You cannot let staff see orders without also seeing margins or salaries.
- No history. When a number is wrong, nobody can tell who changed it or when.
- Fragile formulas. One person understands the formulas, and everyone is afraid to touch them.
- Duplicates. The same customer appears three times with different spellings.
- Copy-paste between tools. Data is retyped into QuickBooks, the CRM or email every day.
- Size and speed. Files take minutes to open or hit row limits.
- Field access. People on site need the data on a phone, and the spreadsheet is unusable there.
Three or more of these, with more than a handful of people depending on the data, usually means the spreadsheet costs more in errors and hours than it saves.
The options in between
| Option | Good for | Limits |
|---|---|---|
| Shared Google Sheets / Excel online | Small teams, simple lists | Weak permissions, no relational integrity |
| Airtable, Smartsheet and similar | Light relational data, quick setup | Per-seat pricing, record limits, logic gets complex, vendor lock-in |
| Microsoft Access / FileMaker | Single-office desktop databases | Poor fit for remote teams, browsers and integrations; shrinking talent pool |
| Low-code platforms | Internal forms and simple workflows | Per-user cost, platform limits on complex logic |
| Off-the-shelf software | Standard processes (CRM, accounting, inventory) | You adapt to the product |
| Custom database + web app | Specific data, rules and integrations | Upfront build; needs an owner on your side |
Try the cheapest option that fits. Many businesses should move from spreadsheets to an off-the-shelf product, not to custom software. Custom is the right call when your data model is specific to your business, when several systems must share one source of truth, or when per-seat tools become expensive as the team grows.
What a custom database project looks like
- Collect every spreadsheet and report; list the real entities behind them.
- Design the data model in PostgreSQL and review it in plain language.
- Build a web interface with role-based permissions and an audit log.
- Migrate and clean the data, reconciling totals with the original files.
- Add reports, exports and integrations with accounting and other tools.
A focused database for one department typically takes 4–6 weeks; larger systems with several roles and integrations 8–10 weeks or more. See custom database development and business automation.
A quick self-test
Answer yes or no: more than five people edit the data; you need different access for different roles; mistakes cost money or customers; the data is re-entered into another system; people need it on a phone in the field; you need to know who changed what. Four or more “yes” answers mean a proper database will pay for itself in fewer errors and fewer hours. Two or fewer — keep the spreadsheet and revisit in a year.
Keep spreadsheets where they belong
Moving to a database does not mean banning spreadsheets. The best setups export clean data from the database into a spreadsheet for analysis — the database becomes the source of truth, and the spreadsheet goes back to doing what it does best.

Questions we are asked most
When should a small business switch from Excel to a database?
When several people depend on the same data and you see version conflicts, missing permissions, no change history, duplicates or daily retyping between tools. One or two users with low-stakes data can stay on spreadsheets.
Is Airtable a database?
It is a hosted relational tool with a spreadsheet-like interface. It is a good middle step for light data; teams usually outgrow it when logic gets complex, records grow or per-seat costs rise.
Is Microsoft Access still a good choice?
For a single office on Windows it still works, but it fits poorly with remote teams, browsers, phones and integrations. Most Access replacements move to a web app on PostgreSQL or SQL Server.
Can we still use Excel after moving to a database?
Yes. Exports and live connections let you analyze data in Excel or Google Sheets while the database stays the single source of truth.
