When off-the-shelfwon't quite do.

Sometimes the software you have nearly does the job, but not quite. That's where a small custom tool or a direct API connection pays for itself. We build focused tools around Xero and your other systems, designed for one job and done well.

What's included

Internal tools

Simple web tools for quoting, job tracking, approvals or checks, built around how your team works.

Spreadsheet replacements

Fragile spreadsheets turned into proper tools with logins, checks and a record of changes.

Direct API connections

Links between Xero and your other software, built for exactly the data you need.

Hosting and support

Hosted at low cost and kept running, with changes made as you grow.

How we approach it

We build the same way we built our own software, 39 Apps: small, focused and tested against real data. You get a tool that does one job very well, rather than a sprawling system you'll never fully use.

Every build starts with a short specification you can read and agree, so you know exactly what you're getting and what it costs before work begins.

What you get out of it

Built around you

Tools that fit the way you work.

Less fragile

Key processes off risky spreadsheets.

Low running costs

No big software bills.

Custom Tools and APIs questions

What's an API, in plain English?

It's the door a piece of software leaves open so other software can read from it or send information to it, safely and automatically.

Who owns what you build?

We agree that in writing before we start. For tools built for your business, the usual answer is you.

Is a custom tool expensive?

It doesn't have to be. A focused tool is often cheaper over a couple of years than another monthly subscription.
