Notes on custom software for SMEs

The true cost of manual processes, the true cost of custom software in 2026, and how AI has changed the economy.

Three figures: diagnosis €1,900, project €6,900–€14,900 and license €390/month.

How much does custom software cost in Spain (2026)

In Spain, as of September 2026, Wallion publishes three figures: Diagnostics €1,900 (discounted if you continue), development €6,900–€14,900 for an internal workflow/internal tool only, and licensing from…

When to build an MVP — and when it's not worth it.

When does an MVP make sense?

An MVP makes sense when there's a stranger, an action, and a cue that you can write down before building. If any of those three are missing, you're not asking for an MVP: you're asking for something else—or you don't know what yet.

MVP or internal tool

An MVP and an internal tool are similar in size. Both can be completed in weeks. Both involve cutting costs. They're not the same work—not the same price range, not the same "done" criteria.

A fixed price in writing versus an open hour meter.

Fixed price or per hour

Hourly rates sound flexible. Fixed price sounds expensive. Neither is "better" until you specify who pays when the scope changes.

The smallest piece that a stranger can truly end up with.

What is a studio MVP?

A studio MVP isn't "the cheap version of the product." It's the smallest piece that an outsider can actually finish—built by a studio with a written scope, fixed price, date, and someone on board…

A trigger, an action, and a location where the failure is seen — AI automation in an SME.

What is AI automation for SMEs

AI automation for SMEs isn't a passing fad. It's about eliminating a step you already know how to do, a repetitive one, and one that's noticeable when it fails—and, when it adds value, using AI to classify, draft, or route information…

Repo, admin and contract — not an agency black box.

Who gets the code?

“The code is yours” appears in almost all the proposals. It doesn't mean the same thing twice.

A steady step in a line, versus a flow full of exceptions.

When to automate a process (and when not to)

Automation isn't about "putting intelligence" on top of the chaos. It's about removing a step you already know how to do, a step that's repeated, and whose failure is obvious.

The sheet that no longer closes the month — a flow, an owner, an official number.

Leave the spreadsheet

The spreadsheet starts off well. One process, one person, one month ending. The problem isn't Excel. The problem is when the month no longer fits in a single cell.

Integrate what you already have or build

You have three tools you already pay for. You manually cross-reference them each month. The temptation is to "make an app." Sometimes the missing piece is a cable. Sometimes the cable doesn't exist because the process doesn't fit within any of the…

An open backlog list, versus a closed scope with a date.

Reinforcement or closed project

Sometimes you need a couple of extra hands on a backlog you've already sent. Sometimes there's a piece missing that no one in-house is going to finish. They're similar in that someone from outside gets involved. They're not similar in who decides what's finished.

A catalog tool that covers part of the month, versus one tailored to the process.

2026-08-31

Custom or standard software

The catalog tool does 60% and charges 100%. The custom-made tool promises 100% and, if the scope isn't written, charges twice. The decision isn't "modern or old-fashioned." It's what part of your month you don't pay for…
