The verdict in three sentences
Custom real-estate development software costs 40,000 to 100,000 EUR in 2026 depending on modules (projects, units, reservations, notaries, accounting). The line that repays the project is absorption-rate steering: spotting a slowing project a week earlier is worth a lot. Add accounting integration and 8-12 %/yr maintenance for a controlled TCO.
Cost per module in 2026
A developer isn't steering a plain CRM: they track projects, units with evolving status, reservations with legal cooling-off, notary deeds and fund calls. Here are 2026 ranges.
| Module | Indicative cost | Lead time |
|---|---|---|
| Project management | 8,000-16,000 EUR | 2-3 wks |
| Unit and status tracking | 7,000-14,000 EUR | 2-3 wks |
| Reservations + legal cooling-off | 6,000-13,000 EUR | 2-3 wks |
| Notary and deed tracking | 5,000-11,000 EUR | 1-2 wks |
| Fund calls | 6,000-12,000 EUR | 2 wks |
| Accounting integration | 6,000-14,000 EUR | 2-3 wks |
| Project dashboard | 5,000-10,000 EUR | 1-2 wks |
| Typical project total | 40,000-100,000 EUR | 12-22 wks |
A developer running 3-6 active projects usually lands around 60,000-75,000 EUR.
Dashboard and steering ROI
The value of a development tool shows in decision speed. Compare spreadsheet steering with real-time steering.
| Metric | Spreadsheet | Custom tool |
|---|---|---|
| Project consolidation lag | 3-5 days | Real time |
| Detecting a slowdown | +2-3 weeks | Immediate |
| Reservation-tracking errors | Frequent | Rare |
| Assistant time/mo | 30-40 hrs | 8-12 hrs |
| Time cost (35 EUR/hr) | 1,050-1,400 EUR | 280-420 EUR |
| Monthly saving | — | ~1,000 EUR |
On top of that sits the hard-to-quantify but real value of a commercial decision taken earlier on a unit that isn't selling.

Mini case study
Sophie runs a development company in Berlin managing 5 active projects, about 180 units. Her team spent 35 hrs/month consolidating spreadsheets, i.e. 1,225 EUR/month at a loaded 35 EUR/hr. A custom tool at 68,000 EUR cuts this to 10 hrs/month (350 EUR), saving 875 EUR/month. Crucially, the dashboard let her reprice a slow-moving unit two weeks earlier, avoiding roughly 3 months of carrying cost on a 280,000 EUR unit (estimated carry ~1,400 EUR/month). Direct payback: about 40 months on time alone, but far faster once commercial-steering gains are included.
FAQ
Isn't a standard real-estate CRM enough? Rarely: CRMs handle contacts, not unit statuses, fund calls or notary tracking. Custom at 40,000-100,000 EUR models the full development cycle.
Can accounting be integrated? Yes, via a connector to your accounting software. Budget 6,000-14,000 EUR for a reliable integration of entries and fund calls in 2026.
What's the lead time? 12 to 22 weeks for full coverage. A first unit-tracking module can ship in 6-8 weeks.
From how many projects is it worth it? From 3-5 active projects, when manual consolidation exceeds 25-30 hrs/month and delays commercial decisions.
What maintenance budget? Count 8-12 %/yr of development, i.e. 3,200-12,000 EUR/yr for a 40,000-100,000 EUR project.
