Pricing

The prototype first. Then a fixed price.

For companies that want to know what their software costs before anyone builds it. In 21 days you click through a prototype, then the fixed price for the build stands. Prototype from €5,490, development from €15,000.

Louis Nell, Managing Director of KNGURU

Three prices you know up front.

We charge for the prototype, the build and the running separately. After each step you decide whether to go on.

What every price includes.

It is in the contract, however big the project.

  1. 01

    The agreed price is the final price

    After the prototype the price is fixed. Change requests get a number before we start them, never after.

  2. 02

    Code, design and accounts are yours

    Repository, Figma files and hosting accounts run in your name. If you carry on without us, nothing is missing.

  3. 03

    We also tell you what you don't need

    If the software makes no sense after the prototype, you hear it from us. The prototype is yours, you don't have to go on.

  4. 04

    An answer within one working day

    Management reads your request in person. You get an answer within one working day, no ticket, no queue.

Common questions about pricing

What companies want to know before the first call.

Why is the prototype paid separately?

Because afterwards you know whether the build is worth it and what it costs. If you go ahead, the prototype is fully credited to the build. It costs from €5,490.

What exactly does development cost?

That depends on what the software has to do. It starts from €15,000, and you get the exact fixed price after the prototype. For apps, our page on app costs shows our prices and what drives them.

What is in support and further development?

We keep your software secure and up to date, fix bugs and add new features, from €1,990 a month.

What does it cost to win users?

We help from €3,990 a month. That is how our own app DeepDays reached 60,000 users.

Do I have to book everything with you?

No. After the prototype you decide whether to go on. The prototype is yours, you don't have to continue.

Does the call cost anything?

No, the call is free. We look at your plans and tell you which step fits.

Book your free call.

We look at your plans with you as if they were our own. If the build isn't worth it, we'll tell you, even if that means no project.
