Clear. Core to Kern.

Custom software for a fixed price.

We build and automate software for companies worldwide. We agree what you're getting and when it goes live before we start. You own the code.

Fixed price. Core to Kern.

The risk shouldn't sit with you.

With hourly billing, you pay when the work takes longer. At Kern, we agree a price for the work before we start. That price holds.

Others vs Kern
PriceOthersHourly rate, open-endedKernOne fixed price, agreed up front
PlanningOthers“Let's see how far we get”KernPhases and a delivery date before the first line of code

Scope changes along the way? We talk about it openly, before we build any further.

Predictable. Core to Kern.

Here's how your project runs.

Four phases, with the work and costs agreed at each stage. You always know what comes next.

  1. Intro & mapping

    We map your goal, your process and the bottlenecks worth solving. If custom software isn't the answer, we say so.

    No obligation
  2. Blueprint & quote

    You get it on paper: what we build, in which steps, and why. With one price that holds.

    Fixed price
  3. Build, test & deliver

    We build in short rounds. You can try the software while we're working on it.

    Short rounds
  4. Live & keep improving

    Code, documentation and access transfer to you. Hosting and maintenance are available, never required.

    100% your code

Here's what that looks like in practice.Read the full process
