Custom tools: from scattered lists to software that fits

Plenty of businesses run on a spreadsheet that was handy once. Now five people work in it, things regularly go wrong and only the person who made it still understands how it works. I build a tool that does exactly what you need, and nothing more.

From €3,000 fixed price after the Quickscan

Sound familiar?

  • 01 · Locked out

    Someone has the file open, so nobody else can get in.

  • 02 · One formula

    One wrong formula and the schedule no longer adds up.

  • 03 · Workarounds

    Your software does 80% of what you want, and the rest takes workarounds.

It doesn't have to be that way. I build a tool that works the way your business works, for the whole team at once.

Custom tools · 4 kinds

  • Planning and scheduling tools

    Everyone sees the same schedule, and changes are right straight away.

  • Quoting and costing tools

    Prices and margins in one place, and a quote in a few minutes.

    Every number you need on one screen.

  • Customer portals and online checks on your website that bring in leads

    Customers sort out what they can themselves, and requests arrive complete.

How it works, step by step

Two ways in, one way out. Know what the tool has to do? Start with a call. Not sure yet? Start with the Quickscan.

  1. Step 1 of 4 · Intro call

    You tell me where it hurts

    You tell me how the work goes now and where the list gets in the way. If it's clear enough, we go straight to a proposal.

    What it costs
    Free
    How long
    30 minutes
    What you do
    List your software and time sinks beforehand
  2. Step 2 of 4 · Quickscan

    We work out what could be better

    I look at your lists, how the work flows and what a tool of your own would change. Within 5 working days you get a report with solutions and prices.

    What it costs
    €250 incl. VAT
    How long
    Report in 5 working days
    What you do
    One conversation of 45 minutes
  3. Step 3 of 4 · Build

    I build, you follow along

    Along the way you click through working versions yourself, not status reports. A custom tool is often done within 4 to 8 weeks.

    What it costs
    From €3,000 fixed price after the Quickscan
    How long
    Set out in the proposal

  4. Step 4 of 4 · Handover

    It’s yours

    Your software runs and you don’t depend on me. Want me to look after it? That’s possible for a fixed monthly fee.

    What it costs
    Included
    How long
    At handover
    What you do
    Nothing — it’s yours

Frequently asked questions

Short answers, all on the table.

Question not listed? Just ask me.
Your data

What happens to the data in our current spreadsheets?

It moves along. I import your existing lists into the new tool, so you start with everything you already have instead of an empty screen.

Team

Does my whole team need to learn something new?

The tool is built around the way you already work, so there’s little to learn. At handover I walk your team through it, and the documentation stays with you.

Growing

What if we need more later?

Then we extend it. The code is yours and documented, so I can build on it, and so can another developer if you’d rather.

Which list can go?

In a free intro call you tell me how the work goes now. In the Quickscan I work out what a tool of your own would bring.
