“What does it cost?” is the most common question in our first customer talk – and at the same time the most difficult.

This article gives you the numbers we have learned after 250+ projects.

The short answer: Custom software costs between €20,000 and €250,000, depending on complexity, interfaces and quality needs. Most midsize projects are between € 40,000 and € 120,000.

Why "What does software cost?" has no easy answer

Short: Unlike house construction, there is no catalogue.

Unlike house construction, there is no catalogue. Each software project is unique – the needs, interfaces, user groups and scaling scenarios differ.

An honest offer requires at least half a day requirement review.

What we can say anyway: there are typical patterns. And we'll show you these.

The most important cost factors

Interfaces with third-party systems

Any connection to an existing system – ERP, CRM, accounting, webshop – costs development time and test effort. A well-recorded REST API is linked in 2–3 days.

A 20-year-old commodity management system without API sometimes costs as much as the actual application.

Every non-triviale interface costs 3,000 to 12,000 € in addition.

User roles and permissions

Short: An app with a single user type is simple.

An app with a single user type is simple. As soon as there are different roles (admin, specialist, external service, customer) with different rights, the complexity increases disproportionately.

Offline capability (especially for apps)

An app that works without internet (e.g. for field services without net coverage) is significantly more expensive than a purely online-based solution.

Data synchronization, conflict detection and offline storage often double the development effort.

Regulatory requirements

GoBD, GDPR, ISO 27001, CE marking or industry-specific standards (medicine, finance, public sector) require extra documentation, auditability and sometimes certified development processes.

fixed price or time & material?

Short: This is not an academic question – it decides about your financial risk. .

This is not an academic question – it decides about your financial risk. .Festpreis is suitable if the needs are clear and a detailed specification exists.

You know the budget in advance, the risk lies with the service provider. Condition: Changes during the project cost extra (Change Requests).

Time & Material is suitable for explorative projects, fast prototypes and projects where needs develop agile.

The budget is more flexible, but you bear the risk of budget overruns.

Our recommendation: Requirement review and concept always as a fixed price package. The actual development according to the specifications also as a fixed price, with defined change-request processes.

Why cheap often gets expensive

An offer that is 30% below the market average is usually one of three things: naive estimate, omitted services or offshore resources with hidden communication costs.

What we see regularly in practice:- Onboarding costs for agency change: €20,000–50.000 to understand a foreign system

• Refunding if 80% are finished, but the product is not yet usable.
• Fehlende Tests lead to expensive bugs in live operation.

An honest offer includes: requirement review, architecture, development, testing, deployment, introductory training and 6 months of initial maintenance contract.

Frequent questions about software development costs

Short: What is the difference between custom software and a SaaS solution?

What is the difference between custom software and a SaaS solution? SaaS software is a monthly rented standard solution.

Custom software belongs to you, is exactly tailored to your processes and does not contain permanent license costs. Amortization typically after 3–5 years.

Can we build a MVP for under €20,000? For very clearly defined applications (1 process, 1 user group, no complex interfaces). Yes.

This should then also be a real MVP – not the "repeated version". Of the full system.

How long does a typical project take? Small projects (up to €30,000): 4–8 weeks. Medium projects (30,000–100,000 €): 3–6 months. Large projects (100.000+ €): 6–18 months.

Do you have fixed price guarantee? Yes, on the basis of a detailed specification.

Changes after approval of the duty booklet are calculated and commissioned separately as change requests.
