What would your software cost to build?

Tell us what you are building, what it needs to do and what it has to talk to. You get a costed estimate, a timeline and a list of what is included, in about three minutes. It is a guide to work from rather than a quote, and a real price needs a proper scoping conversation.

Step 1 of 6

No sign-up needed

What kind of business are you?

It sets the language, the suggestions and the systems we expect you to be running.

Who is going to use it?

This changes what we ask next, and whether we can work out a return for you.

Where does it need to run?

Pick everything that applies.

What does it need to do?

Pick everything that applies. You can be generous; we phase the build so the first release is useful on its own.

What does it need to talk to?

Integrations are one of the biggest things that move a price, and most estimates leave them out. Pick the ones you use. If it is not listed, tell us and we will price the discovery work in.

A few last things

These change the effort more than most people expect.

How many people will use it?

Does it hold personal or payment data?

Is it replacing something you already use?

What does this work cost you today?

Only so we can work out what the system pays back. Best guesses are fine, and you can skip it.

Payback

This is a guide, not a quote.

The figures come from your answers and our engineering day rate. A real price needs someone to look at your systems, your data and how you actually work, and it can come out higher than this. Undocumented systems, awkward integrations, regulatory requirements and data that needs cleaning before anyone can use it all add days. Treat this as the starting point for a conversation, and the number we put in writing after scoping as the one that counts.

What it costs, and what the time is worth

Value of freed time Everything you pay

Where blue crosses grey, the system has paid for itself.

What that includes

Everything below is inside the figure. Nothing here is an extra.

Worth having, and not counted above

The payback figure only counts hours. These are the things our clients tell us mattered just as much, and we have deliberately left them out of the numbers.

Free, 30 minutes, no obligation

Talk this through with the engineer who would build it

Thirty minutes on a call, looking at what you actually need, turns this illustration into something you can budget against. We will have read your answers before we ring.

A guide, not a quotation. Estimates are built from the answers you give and can come out higher once the work is scoped properly. For the day rate and the bands behind these numbers, read what custom software costs in the UK. For how we scope and build, see custom software.
