The verdict in three sentences
A property developer's software requirements in New York rest on three critical modules: price grid, reservations and progress draws. A custom build costs USD 85,000-145,000 over 20-28 weeks, with accounting and closing-agent integration essential. Well specified, it cuts up to 25% off the sales cycle by smoothing the path from reservation to closing.
The modules to price in the spec
A developer's spec is structured module by module, each with its business rules. Here is the 2026 order of magnitude for the New York market.
| Module | 2026 budget (USD) | Timeline | Key business rule |
|---|---|---|---|
| Per-program price grid | 14,000 - 24,000 | 3-4 wks | Units, tax, options, changes |
| Reservations and pipeline | 18,000 - 30,000 | 4-5 wks | Statuses, holds, legal delays |
| Progress draws | 17,000 - 29,000 | 4-6 wks | Schedule by construction stage |
| Delivery/punch-list tracking | 12,000 - 22,000 | 3-4 wks | Reserves, sign-offs, reports |
| Accounting + closing integration | 14,000 - 26,000 | 4-5 wks | Ledger export, closings |
| Project total | 85,000 - 145,000 | 20-28 wks | Excludes hosting |
At the USD 950/day rate for a senior profile in New York, a median USD 115,000 build represents roughly 165 person-days over 20-28 weeks, including a functional scoping phase essential to lock the draw rules.
Progress draws: the most sensitive module
The draws module is the legal and financial heart of development. Each draw is triggered by a construction stage (foundations, weathertight, completion). The software must automatically compute the schedule percentages and generate the notices.
| Construction stage | Cumulative cap | Trigger | Automation |
|---|---|---|---|
| Foundations | 35% | Foundation sign-off | Auto-generated draw |
| Weathertight | 70% | Weathertight sign-off | Draw + reminder |
| Completion | 95% | Completion report | Draw + balance |
| Delivery | 100% | Key handover | Balance + reserves |
| Warranty | Optional holdback | Reserve release | Holdback release |
Automating these draws removes manual calculation errors and speeds collection. Plan maintenance of USD 1,200-2,100/month covering rule changes, new programs and closing-agent integrations.

Mini case study
Mark runs a mid-sized property developer in New York, with 4 active programs and 180 units per year. Before the software, reservations and draws were handled on spreadsheets and manual letters, with an average 12-day delay between reservation and signed reservation contract. The build at USD 115,000, plus USD 1,700/month maintenance, automates the grid, reservations and draws. By cutting the sales cycle by 25% (from 12 to 9 days), Mark accelerates collection on 180 units per year and legally secures each draw: on a multi-million-dollar program revenue, one year's cash-flow gain covers the investment.
FAQ
Which modules are essential in developer software? The price grid, the reservations pipeline and the progress draws. Delivery tracking and accounting/closing integration come next but are strongly recommended from the first program.
What does the draws module cost? Between USD 17,000 and 29,000 depending on schedule complexity and program count. It is the most sensitive module because it touches legal compliance and cash flow.
What is the timeline for a well-specified project? Plan 20 to 28 weeks of development, preceded by 3-4 weeks of functional scoping to lock the business rules before any code.
Should we integrate accounting and closing agents? Yes, it avoids double entry of ledger and closing data. Budget USD 14,000-26,000 for these integrations, which secure financial and legal reconciliation.
What maintenance budget should we plan? USD 1,200-2,100/month depending on program count and regulatory pace. Maintenance also covers new program setup and tax updates.
