Custom software for small businesses and sole proprietorships

Most examples come from companies with their own IT departments. What can be transferred to a business with three to fifteen people — and what cannot.

In short

For businesses with three to fifteen people, custom software is often more effective than for large companies, because the same person has multiple roles. But the approach must be different: small scope, few moving parts, maintenance without specialist knowledge — not a solution designed for growth to fifty employees.

01 — Business size

What this means for small businesses

Most examples online come from companies with their own IT departments. In a business with three to fifteen people, different rules apply: there's no one to maintain a system on the side, and every hour spent on implementation is taken directly from day-to-day operations.

This does not mean that custom software is unsuitable for small businesses — on the contrary, the impact is often greater there because the same person has multiple roles. It does mean that the approach must be different: small scope, few moving parts, maintenance without specialist knowledge.

A sole proprietorship doesn't need a solution designed for growth to fifty employees. Anyone who buys something like that pays for complexity that will never be used.

02 — Fit

When it's worth it

  • The process in question occurs at least weekly.
  • It follows rules you can write down — even if there are exceptions.
  • Today it's manual work that no one enjoys doing.
  • There's one person who decides, not three who need to coordinate.
  • You can name what would tell you it worked.

03 — Calculation

How to calculate it

Four numbers are enough: How often does the process occur? How long does it take? What does an hour cost internally? And what does the solution cost — one-time plus operation over three years?

An example: A process that occurs twice a week and takes 40 minutes each time ties up around 69 hours per year. At an internal hourly rate of 45 euros, that's roughly 3,100 euros per year locked in there. If a solution reduces this effort by two-thirds, it often pays for itself — depending on the actual quote — within one to two years. We'll give you the exact figure for your case after the initial meeting.

This calculation is deliberately conservative: it only accounts for the time saved, not the errors avoided or the orders that come through due to faster response. In practice, the benefit is usually higher — but you shouldn't count on it before you've measured it.

04 — Questions

Frequently asked questions

When does custom software pay off compared to standard software?

When your process is a genuine competitive advantage, when standard software only fits seventy percent and the rest ends up as manual work, or when license costs per user exceed the development cost over a few years. If it's only about convenience, standard software is cheaper.

Can we start with a spreadsheet?

Often yes, and that's a good test. If the spreadsheet maps the process and only fails due to multi-user capability, permissions, or data volume, the requirement is clear and the project is calculable.

What happens if we no longer work together?

You have the code, documentation, and access. We deliberately use widespread technologies so that a switch is possible without someone having to rebuild everything.

Does this run on our own servers or in the cloud?

Both are possible. For most businesses, a cloud solution is lower-maintenance; where data must not leave the premises, we set it up on your own infrastructure.

What if we discover new requirements during development?

That's normal and planned for, because we work in small steps. A new requirement is incorporated into the next step, instead of stalling the entire project.

How do we avoid the project going off the rails?

Small steps with usable results, fixed budgets per step, and the option to exit after each step. Large fixed-price projects over twelve months are the most reliable path to disappointment — for both sides.

How many users can a system like this handle?

That depends on the architecture, which we plan according to your expected growth — from a few users in your own business to several hundred across multiple locations.

05 — Decision

How to move forward

The most affordable next step is a conversation, not a quote. Twenty minutes is usually enough to clarify whether a project makes sense, what scope it involves, and whether we're the right fit.

If we're not, we'll say so. An honest no costs less than a project you abandon after three months — for both sides.
