Custom software agencies in Berlin compared
If you want custom software built, you're not looking for a vendor, you're looking for a team that knows your stack and won't stay indispensable after handover. Here you compare custom software development agencies by technology, minimum budget, contract model, and verified proof, with no paid ranking.

Custom software is not off the shelf
The difference from standard software sounds trivial, but it isn't: custom software isn't adapted, it's designed. Dispatch systems, customer portals, internal tools, interfaces between programs that were never really built for each other. All of it is built from the ground up, shaped around a process that doesn't exist anywhere else in quite the same way. The term "software agency" doesn't help much here, since it covers everything from a two-person studio to a two-hundred-person software house. What matters more than size is whether the stack, industry experience, and collaboration model fit your project.
What matters when choosing an agency
Most people start with the question of stack, and rightly so: an agency that works in TypeScript or Java every day delivers something different from one that has "also worked with it before." On techagenturen.de, profiles separate core expertise from supplementary experience, and both are filterable.
Just as important, but more often overlooked: who owns the code in the end. That sounds like a formality, but it's exactly where many projects get expensive later. If the rights to the code aren't contractually yours and nobody plans for a handover package of repository, deployment documentation, and an operations manual, the agency stays the only one who really understands the system for years to come.
Proof is a third criterion, and skepticism toward logos pays off here. An ISO 27001 certificate or an AWS partner status can be verified, a customer logo on a website cannot. On our site, proof only appears on a profile after we've seen the document. The same applies to references: "cut turnaround time from four days to a day and a half" is a statement, "successfully implemented" is not.
And finally, the contract model. Fixed price suits clearly scoped projects, Time & Material suits iterative development, a Dedicated Team suits long-term collaboration. An agency that explains when it recommends which model, and when it doesn't, has usually been through a few projects where the wrong choice got expensive.
What custom software costs
Agencies in Germany typically charge between €100 and €180 per hour. Owner-run teams staffed with senior developers tend toward the upper end, nearshore models with German project management run €60 to €100. Roughly broken down:
- Internal tools and smaller applications: €15,000 to €40,000
- Customer portals, planning systems, system integrations: €40,000 to €150,000
- Multi-role platforms with compliance requirements: from €150,000, often as ongoing development over twelve to twenty-four months
You'll find the minimum budgets of the agencies on this page listed per service area directly in the profile, not as a blanket figure. For maintenance, updates, and smaller extensions, plan for an additional 15 to 20 percent of the development budget per year.
What custom software is typically used for
Most commonly, it's about replacing a grown Excel or Access system with a web application, building customer portals connected to ERP and CRM, or dispatch and resource planning. Add to that data exchange between inventory management, shop, and logistics providers, modernizing a legacy application nobody wants to maintain anymore, and digitizing paper-based processes with approvals and an audit trail.
How the ranking on this page works
It's based on a score that weighs ratings, verified proof, verification status, profile completeness, and activity. A paid plan doesn't change it, ads are marked as such. In the search tool, you can combine stack filters like TypeScript, Java, or AWS with proof, company size, and budget. Or describe your project in a request and receive quotes from up to three matching agencies.
Frequently asked questions
Custom software agencies: questions and answers
What does custom software cost?
Between €100 and €180 per developer hour is common at German agencies. Small internal tools start around €15,000, customer portals and integrations run €40,000 to €150,000, larger platforms cost more. For maintenance, plan for an additional 15 to 20 percent of the development budget per year.
Is custom software worth it, or is a standard solution enough?
Depends on the process. If it matches the market standard and can be adapted with reasonable effort, a standard solution is usually the cheaper choice. If the process is your actual competitive advantage, or if standard software forces expensive workarounds, custom development quickly becomes more economical, especially once license costs add up over the years. Often a mix makes sense anyway: standard at the core, custom at the interfaces.
How long does a project like this take?
For small applications, a first productive version is realistic after six to twelve weeks, for mid-sized projects after three to six months. Larger platforms are built over twelve to twenty-four months in releases. A one- to two-week discovery phase at the start, where scope and architecture get clarified, usually shortens the project rather than extending it.
Who owns the code afterward?
You do, if the contract says so: including repository, build scripts, and documentation. Many providers on techagenturen.de state in their profile whether code ownership sits with the client and whether handover is documented. Clarify this before signing the contract, not after, when your negotiating position has changed.
How do you recognize a good custom software agency?
By proof that can be verified, by references with a measurable result instead of a bare claim, and by a clear answer to the question of code ownership. Another sign: who actually does the development on the project. Feel free to ask about the team, not just management. They rarely write the code themselves.
