The verdict in three sentences
A custom program tracking software for a developer costs between 40,000 and 110,000 EUR in 2026 depending on the number of modules (units, reservations, payment calls, buyer portal, accounting). The gain is not cosmetic: you move from scattered-spreadsheet management to a real-time view of every program. Plan for 4 to 6 months of development and maintenance of 500 to 1,200 EUR/month.
The modules of development software in 2026
A developer runs several trades in parallel: unit sales, financial tracking per program, buyer relations, and coordination with the site. The software must reflect that reality, from reservation deposit to handover.
| Module | Role | Indicative budget (EUR) |
|---|---|---|
| Unit management | Price grid, statuses, options | 8,000 - 18,000 |
| Reservations & sales | Contracts, amendments, withdrawals | 7,000 - 16,000 |
| Payment calls | Staged schedule, reminders | 6,000 - 15,000 |
| Buyer portal | Documents, progress, updates | 8,000 - 20,000 |
| Program reporting | Margin, sell-through, cash | 6,000 - 14,000 |
| Accounting integration | Export to ERP/accounting | 5,000 - 12,000 |
The price grid and staged payment tracking are the business core: that is where spreadsheet errors cost the most. The buyer portal, meanwhile, sharply reduces inbound calls to the sales team.
Licensed development ERP or custom build?
Market development ERPs are powerful but rigid and billed annually. Custom costs more upfront but fits your processes and belongs to you.
| Criterion | Development ERP (license) | Owned custom build |
|---|---|---|
| Entry price | 15,000 - 40,000 EUR setup | 40,000 - 110,000 EUR |
| Annual license | 8,000 - 25,000 EUR/year | 0 |
| 3-year cost | 39,000 - 115,000 EUR | 40,000 - 110,000 EUR + maint. |
| Process fit | Limited configuration | Total |
| Buyer portal | Often a paid option | Included, your branding |
| Ownership & evolution | Vendor lock-in | Owned code |
For a developer launching 2 to 5 programs a year with specific financial structures, custom becomes relevant: it avoids configuration contortions and the buyer portal becomes a real sales argument.
Mini case study
Sophie is CEO of a New York development firm delivering 180 units a year. Three assistants each spent 8 h/week updating price grids, reservations and payment calls in Excel, i.e. 24 h/week at 32 EUR/h loaded, about 39,900 EUR/year. Custom software at 75,000 EUR removes 30 % of that entry (~12,000 EUR/year) and cuts the payment-call errors that generated 2 corrections per program. With fewer reminders and the sales gain from the buyer portal, payback lands around 30 months.

FAQ
Do we really need a buyer portal?
Not mandatory, but it is the module that most improves satisfaction: the buyer tracks progress and finds their documents alone. Budget 8,000 to 20,000 EUR and a clear drop in support calls.
How are staged payment calls managed?
The software generates the regulatory schedule per unit, triggers reminders and tracks receipts. It is the module that eliminates the most costly spreadsheet errors.
Can it integrate with our accounting?
Yes, via API or structured export to your ERP/accounting software. Budget 5,000 to 12,000 EUR depending on the target and desired automation.
What is a realistic go-live timeline?
Between 4 and 6 months for a complete platform. We often ship unit and reservation management first, then payment calls and the buyer portal.
What maintenance budget after delivery?
Maintenance of 500 to 1,200 EUR/month in 2026, covering regulatory evolutions, support, security and small team requests.
