The verdict in three sentences
An internal web application is judged not by its price but by its ROI: it replaces a time-consuming manual process with a tool that saves hours every day. In Berlin in 2026, budget EUR 20,000 to 55,000 and 2 to 4 months, training included. As soon as a tool saves 2 to 5 FTE-hours per day, it typically pays for itself in under 12 months: the annual gain calculation must precede the budget discussion.
What an internal app covers in 2026
An internal application targets a specific process: expense report approval, production tracking, scheduling, document management. Scope is deliberately kept tight to ship fast and prove value.
| Element | Included | 2026 cost (EUR) |
|---|---|---|
| Framing + mockups | yes | 3,000 - 7,000 |
| Core process development | yes | 12,000 - 32,000 |
| Internal roles + rights | yes | 3,000 - 8,000 |
| Exports / reporting | yes | 2,000 - 6,000 |
| Training + documentation | yes | 1,500 - 4,000 |
| Private hosting | recurring | EUR 100 - 400/mo |
Unlike a product aimed at external clients, an internal app can accept a sober design and private hosting: the budget concentrates on process reliability and adoption by your teams.
The ROI calculation: cost vs annual gain
The only figure that matters to a CFO is the net annual gain. Here is how a 2026 investment reads based on hours saved.
| App cost (EUR) | FTE-h saved/day | Annual gain (at EUR 35/h loaded) | Payback |
|---|---|---|---|
| 20,000 | 2 | ~16,000 | ~15 mo |
| 30,000 | 3 | ~24,000 | ~15 mo |
| 40,000 | 4 | ~32,000 | ~15 mo |
| 55,000 | 5 | ~40,000 | ~17 mo |
| 30,000 | 5 | ~40,000 | ~9 mo |
Basis: 1 FTE-hour/day ≈ 220 h/year ≈ EUR 7,700/year at a loaded cost of EUR 35/h. The more time-consuming the digitized process, the faster the payback.

Mini case study
Celine is CFO of a 120-person food-processing SMB in Berlin. Expense report approval ties up 3 people, with re-keying and follow-ups: about 4 combined hours/day. She orders an internal app: framing 5,000, development 22,000, roles 6,000, accounting exports 4,000, training 3,000, i.e. EUR 40,000 delivered in 3 months, plus EUR 250/month hosting. By eliminating 4 FTE-hours/day (about 880 h/year at EUR 35), she saves EUR 30,800/year, not counting fewer errors. The tool pays for itself in about 16 months, then generates a net gain each year after.
FAQ
What budget for a simple internal app? A tool targeting a single process (expenses, scheduling, tracking) sits between EUR 20,000 and 55,000 in Berlin in 2026. Below EUR 20,000, scope is usually too narrow for a real gain.
How to calculate ROI before ordering? Estimate hours lost per day on the process, multiply by 220 days and by your loaded hourly cost (~EUR 35). A tool that saves 3 FTE-h/day returns about EUR 24,000/year.
How long to deliver? 2 to 4 months for a single-process internal app. The tight scope is precisely what enables fast delivery and payback in under a year.
Is training included? Yes, budget EUR 1,500 to 4,000 for training and documentation. It is a profitable item: without team adoption, even the best tool generates no gain.
Can it be hosted internally or privately? Yes, an internal app lends itself well to private hosting (EUR 100 to 400/month). This eases compliance and control of sensitive HR or financial data.
