The verdict in three sentences
A developer doesn't steer a global turnover, they steer independent schemes, each with its own units, stage-payment schedule and cash flow. Bespoke management software (60,000 to 150,000 EUR, 5 to 8 months) replaces the Excel-plus-email patchwork with a live unit tracker, an automated schedule and a buyer extranet. The return shows up in weeks of sales lead time saved and stage payments issued on time, not late.
What the budget funds: cost per module
A developer doesn't need everything at once. Sequence by risk: first the unit tracker and schedule, then the buyer extranet, finally the notary/bank interfaces.
| Module | 2026 cost (order of magnitude) | Timeline | Priority |
|---|---|---|---|
| Unit tracker + reservations | 20,000-35,000 EUR | 6-8 weeks | Core |
| Stage-payment schedule | 15,000-28,000 EUR | 4-6 weeks | Core |
| Buyer extranet | 12,000-25,000 EUR | 4-6 weeks | High |
| Scheme cash-flow tracking | 18,000-32,000 EUR | 6-8 weeks | High |
| Notary/bank interfaces | 10,000-25,000 EUR | variable | Medium |
| Full platform | 60,000-150,000 EUR | 5-8 months | — |
The table that accelerates: sales lead time and cash flow
The hidden cost of Excel steering is the unit sold twice, the stage payment issued late, and the scheme whose real cash position you only know at day +30.
| Indicator | Excel steering | With software | Impact |
|---|---|---|---|
| Unit tracker update | Manual, day +2 | Real time | Zero double reservation |
| Stage-payment issue | 3-5 days after milestone | Automatic at milestone | Cash sooner |
| Sales lead time | Baseline | -10 to 20 % | Less tied-up cash |
| Scheme cash visibility | Day +30 | Real time | Faster decisions |
| Investor reporting | 2-3 days/month | One-click generated | -2 days/month |
Mini case study
Elise runs a development company in Dublin: 4 active schemes, 180 units, 42 M EUR volume. The stage-payment schedule ran on Excel, with 12 to 18 days average issuing delay. Bespoke software at 98,000 EUR (delivered in 6 months) automates issuing at the progress milestone. Across 180 units, bringing each stage payment forward by 15 days mobilised cash earlier and cut bridging-loan needs: the estimated finance-cost saving exceeds 60,000 EUR/year. Add 2 days/month of reporting saved and the tool pays back in a single sales campaign.

What budget for property development software in 2026?
Expect 60,000 to 150,000 EUR for a full platform, delivered in 5 to 8 months. You can start with the unit tracker alone at around 20,000-35,000 EUR.
Isn't off-the-shelf software enough?
Market solutions cover the basics but often stumble on your specific stage-payment schedule and notary/bank interfaces. Bespoke pays off as soon as those flows carry a cash-flow stake.
What does the buyer extranet add?
It centralises documents, works progress and stage payments for each buyer, significantly cutting emails and calls to the sales team while polishing the customer experience.
How does the software improve cash flow?
By issuing stage payments automatically at the progress milestone, without the 3-5 day manual delay, bringing collection forward and reducing bridging-loan reliance.
Can notaries and banks be connected?
Yes, via interfaces or structured exports. It's often phase 2, once the core (units + schedule) is stable, at a cost of 10,000-25,000 EUR.
