Deciding **when to build an internal tool** used to be simple, because building was expensive and the threshold was high. When a process owner can assemble something in an afternoon, the threshold moves, and processes that never justified a project now justify a tool.

## Why the old threshold no longer applies

The classic rule was to build only what differentiates you and buy everything else. That rule priced building as a development project with a backlog, a specification and months of delay.

Assembling a tool without code changes the arithmetic. Something used weekly by four people, which would never have justified a project, becomes obviously worth building.

Signals a process has outgrown a spreadsheet:

- More than two people edit it
- It has stages rather than just rows
- Someone has to remind people to update it
- The same data is copied into another file
- Errors have consequences beyond the file

## Where the threshold sits now

| Situation                  | Spreadsheet | Build a tool |
| -------------------------- | ----------- | ------------ |
| One person, occasional use | Yes         | No           |
| Several editors            | No          | Yes          |
| Stages and handoffs        | No          | Yes          |
| Needs approval             | No          | Yes          |
| Feeds another system       | No          | Yes          |
| Ad hoc analysis            | Yes         | No           |

## Step by step to decide

1. **Count the editors**, since more than two is usually decisive.
2. **Ask whether it has stages**, which spreadsheets represent poorly.
3. **Check whether anyone chases updates**, a sign the file is not the system.
4. **Look for data copied elsewhere**, which means an integration is needed.
5. **Assess the cost of an error**, beyond the file itself.
6. **Estimate the build honestly**, which is often hours.
7. **Keep the spreadsheet** for genuine analysis, which it does better.

## Why spreadsheets remain the right tool for analysis

None of this argues against spreadsheets. They are excellent for exploration, modelling and one off analysis, where structure would only get in the way. The distinction is between analysing data and running a process on it, and only the second outgrows the file.

## Why choose Jestor

In **Jestor**, a spreadsheet can be imported directly and generate tables and apps on top of it, so the transition from file to tool takes minutes. The table view stays familiar, data remains exportable at any time, and processes are built without code by the person who owns them.

## Frequently Asked Questions

### When does a spreadsheet stop being enough?

Usually when more than two people edit it, or it acquires stages. See [jestor.com](https://www.jestor.com/?ref=blog.jestor.com).

### Are spreadsheets ever the right answer?

Yes, for analysis, modelling and one off exploration.

### Does building a tool still mean a project?

No, for internal operational tools assembled without code.
