How much does custom software and web app development cost?

Custom business software with us usually costs between €5,000 and €20,000, depending on complexity. Simpler apps and working prototypes for smaller businesses cost less than €5,000. We agree the exact price as a fixed fee after a free prototype, so you know the cost up front.

How much does a simple app for a small business cost?

An app for one process, such as work orders, bookings, orders or time tracking, usually costs up to €5,000 and is ready in two to four weeks. It is a good fit for smaller businesses that want to replace spreadsheets or paper without a large system. When the business grows, the app can be extended.

How much does a business system covering several processes cost?

A web app covering several processes, with user roles, reports and connections to other systems, usually costs between €5,000 and €20,000 and goes live in four to six weeks. One example is the CRM with billing and a customer portal we built for an internet provider: customers, contracts, monthly invoicing and tax reporting in one place.

What affects the price most?

• Number of separate parts. A client database is one part. If you also need orders, scheduling, invoicing and reports, each part adds work.
• Connections to other systems. Tax and e-invoicing rules, accounting software, card payments or an existing CRM need extra development and testing.
• User roles and permissions. A system used by one person is simpler than one where the owner, managers and field staff see different data.
• AI features. Document reading, request triage or questions about your data add development, but often save the most hours. More in custom AI software.
• Moving existing data. Importing from spreadsheets or an old program is sometimes simple and sometimes needs data clean-up.
• Mobile use. If the app is used in the field, it has to work well on phones and with a weak signal.

How much does maintenance cost?

Beyond the build, plan for a monthly cost for hosting, security updates and small changes. We agree it up front, and it is usually lower than the subscriptions for the several tools your app replaces.

How do you keep the project on budget?

Projects get more expensive when it turns out during the build that the system needs to work differently from what was agreed. That is why it helps to see it before it is built. We handle this with a prototype: in five working days we build a clickable version on your real example, free of charge. Based on it we agree a fixed price for the whole project. After the build, the code is yours.
