Web apps & internal tools

Web apps and internal tools built for your workflow

For when the spreadsheet, the email chain or the expensive SaaS subscription is no longer enough. We build a tool that does exactly what your business needs – no more, no less.

Right for you if

  • you have a spreadsheet that five people edit at the same time
  • you pay for a system where you use 10 % of the features
  • you want customers to book, check status or download things themselves
  • you need a register, an order list or a schedule that works on a phone

Examples of what we build

  • Booking systems with email or SMS confirmation
  • Customer portals where clients see their cases, invoices or documents
  • Order handling and stock lists for a smaller operation
  • Internal scheduling: staff, jobs, vehicles, equipment
  • Forms and workflows that replace paper and email

Price

Fixed price after a short call.

We have a meeting, sketch the workflow together and give you a fixed price for a first usable version. Then we build on in stages, each with its own fixed price.

When you should not build anything

If an off-the-shelf tool solves your problem for a few hundred SEK a month, we will say so. A custom web app is right when the workflow is specific to you, when licence costs have grown, or when you need to connect things that ready-made tools cannot.

Common questions

What does a web app cost?
It depends entirely on scope. A simple booking or register is a small project; a customer portal with login and payments is a larger one. After a call we give a fixed price, and we are happy to split the work into stages so you can start small.
What do you build with?
Next.js and TypeScript on Vercel, with a Postgres database. If you need .NET or Python on the server we do that too.
Can you take over something someone else built?
Usually yes. We look at the code first and tell you honestly if a rebuild is the better option.
Who owns the app?
You. The code lives in a Git repository in your name.
