How Much a Custom Business Application Costs (2026)

A custom business application costs from €800 for a single module to €3,000 for a platform with user accounts and integrations. It is paid once, per project, rather than monthly per seat like an off-the-shelf SaaS.

What raises the priceSix things that move the quote up

raises

Number of roles

An application where everyone sees everything is simple. The moment a manager, a staff member and a client see different things, every screen has three versions.

raises

Integrations

Accounting, e-invoicing, payments, shipping. Every connection to someone else's system is work to wire up and test at the edges.

raises

Migrating old data

Years of history in the old system don't move themselves. Transferring it and verifying nothing fell out is a separate piece of work.

raises

Reports

Listing data is easy. A report that answers a business question requires first agreeing exactly what is being measured.

raises

Field use

If the application is used away from the office it has to keep working when the connection drops, which means reconciling data afterwards.

raises

Regulatory requirements

Fiscalisation, e-invoicing, personal data handling. Not hard, but real work, and it has to be right.

What isn't an extraThree things that come with the job

You own the code

The application is yours. No per-seat licence growing with the team, and no system you can't walk out of with your data.

Works on a phone

If it is used in the field or in a warehouse, it works on a phone. That isn't a separate product, it's part of the same job.

Data export

The data is yours and has to come out to Excel or PDF whenever you need it, without asking us.

Custom or off-the-shelfWhen custom beats a subscription

Off-the-shelf SaaS is faster and cheaper at the start, and for most standard work it is the right call. Custom pays off when the business doesn't fit someone else's mould, when the subscription grows with headcount, or when you pay for ten modules to use two. The arithmetic is simple: subscription × people × 36 months, then compare.

Off-the-shelf SaaSCustom application

Cost over three yearsA per-seat subscription every month, growing with the team.Paid once. The tenth user costs the same as the first, which is nothing.
