How much does a custom internal tool cost?

A focused internal tool or dashboard — the kind that replaces a business-critical spreadsheet — typically starts in the low-to-mid five figures, roughly £15k–£40k, depending on what it does and what it connects to. It's often the lowest-risk first build and the entry point to a wider system.

Bands follow general custom-software pricing (2026 market pricing guides).

The bands

What an internal tool costs.

  • Simple tool / dashboard — ~£15k–£25k: one job, done properly, off the spreadsheet.
  • Tool with integrations — ~£25k–£40k+: pulling live data from your systems.
  • What moves it — data sources, users, logic and reporting.
  • Where it leads — a focused tool often grows into a platform.
Why start here

The low-risk first build.

An internal tool is a great place to start: a contained scope, a clear before-and-after, and a fast win that proves the value before a bigger commitment. Replace the spreadsheet that one person 'knows' with a real tool, and you've removed risk and returned hours — and laid the foundation for what connects to it next.

How much does a custom internal tool cost?

What's the cheapest custom software I can build?

A simple internal tool or dashboard is usually the lowest-cost starting point, from around £15k–£25k — a contained scope that replaces a spreadsheet and proves the value quickly.

What drives the price of an internal tool?

The number of data sources it pulls from, how many people use it, the complexity of its logic, and the reporting it produces. A standalone tool is cheaper than one wired into several systems.

Can a custom tool replace our business-critical spreadsheet?

Yes — that's a common reason to build one. It gives you one source of truth, proper permissions, an audit trail, and validation, removing the version chaos and key-person risk of a spreadsheet.

Is an internal tool a good first project?

Often the best one — contained scope, fast win, clear value, low risk. It proves the approach before a larger build and frequently grows into the wider platform.

Will it connect to our other systems?

It can — pulling live data so the tool shows the real, current picture rather than a copy someone has to update. Integration is part of the scope.
