Custom software

Spreadsheets and copy-paste work only go so far. We build small, reliable web apps that fit how you already work, and we price them before we start.

Starts with a $450 scoping sprint, credited to the build.

Who it is for

  • Founders who need a working first version in front of real customers.
  • Small professional firms, such as engineering, surveying and design practices, that run projects on spreadsheets.
  • Teams whose tools do not talk to each other.
  • Anyone who wants to run a job board or niche marketplace, since we run two of our own.

Problems we solve

  • Your team retypes the same project, quote or timesheet data into three different places.
  • Off-the-shelf software almost fits, but not quite, and you pay for features you never use.
  • Agencies quote big numbers with no clear scope or end date.
  • A previous build has no tests, no documentation, and nobody who understands it.

What is included

  • Scoping sprint

    A paid sprint that turns your idea into a written spec, a screen list and a fixed quote. The fee is credited to the build.

  • Web apps and portals

    Project trackers, quote and proposal tools, timesheets, client portals and dashboards, built with Nuxt and Vue.

  • Integrations

    Payments with Stripe, email, and connections to the tools you already pay for.

  • Security built in

    Secure headers, input validation, secrets kept out of code, and dependency updates from day one.

What you get

  • Source code in a repository you own, with a README and setup instructions.
  • Automated checks and deploys from day one.
  • A short handover covering how it works and how to make common changes.
  • Optional care plan or monthly development after launch.

FAQ

Frequently asked questions

Why a paid scoping sprint?

A fixed price is only honest when the scope is clear. The sprint gives you a written spec you own, and the fee is credited to the build if you go ahead.

What stack do you use?

Usually Nuxt and Vue for apps, and Astro for content sites, hosted on Cloudflare. They are fast, secure and inexpensive to run. We explain the choice before we start.

Do we own the code?

Yes. Code, repositories and accounts are yours.

What does "from" cover?

The entry price covers one user role, sign-in, up to 5 screens and one integration. Bigger apps with payments, admin dashboards or several user types get a fixed quote after the sprint.
