The verdict in three sentences
For a developer handing over 400 units a year, managing off-plan buyers through email and spreadsheets costs more than dedicated software from year two onwards. A custom tool covering unit inventory, stage-based payment calls, options and buyer modifications, and snagging costs between EUR 50,000 and 110,000 (about USD 54,000 to 120,000) in 2026, with a 5-month delivery. The realistic target is 40% fewer inbound calls to customer relations, thanks to a buyer portal fed with construction photos.
What the software must cover, module by module
An off-plan buyer journey lasts 18 to 30 months, from reservation to snag clearance. Every stage triggers repetitive questions: "how far along is construction?", "when is the next instalment due?", "has my kitchen upgrade been approved?". The software answers them before they become a phone call. In Dubai, payment plans are tied to construction milestones and escrow rules, which makes automated, milestone-based calls especially valuable.
| Module | Function | Indicative 2026 cost | Expected impact |
|---|---|---|---|
| Unit inventory and reservations | Real-time availability, holds, reservation contracts | EUR 10,000 - 20,000 | No more double bookings |
| Stage-based payment calls | Milestone schedule (e.g. 35% foundations, 70% structure, 95% completion), automatic reminders | EUR 8,000 - 18,000 | Cash collected 10 to 15 days earlier |
| Options and buyer modifications | Upgrade catalogue, modification quotes, site manager approval | EUR 8,000 - 20,000 | Fewer ordering errors with contractors |
| Buyer portal | Personal space, monthly site photos, signed documents, messaging | EUR 12,000 - 25,000 | -40% inbound calls |
| Handover and snagging | Tablet inspection, photos, assignment to trades, deadline tracking | EUR 7,000 - 15,000 | Snags cleared in 60 days instead of 120 |
| Connectors (ERP, legal, e-signature) | Accounting sync, document filing, Docusign or similar | EUR 5,000 - 12,000 | Zero re-keying |
A core scope (inventory, payment calls, simple portal) fits within EUR 50,000 to 65,000. The top of the range, around EUR 110,000, is a complete tool with advanced modification management, a tablet handover app and integration with the developer's ERP.
Custom build, developer software package or generic CRM?
Three options exist in 2026. The choice mostly depends on unit volume and how specific your processes are.
| Criterion | Adapted generic CRM | Developer software (SaaS) | Custom software |
|---|---|---|---|
| Setup cost | EUR 10,000 - 25,000 | EUR 15,000 - 40,000 | EUR 50,000 - 110,000 |
| Annual subscription | EUR 8,000 - 20,000 | EUR 25,000 - 60,000 (often per unit delivered) | Hosting and maintenance: estimate EUR 8,000 - 15,000 |
| Native stage-based payment calls | No, custom development | Yes | Yes, following your rules |
| Branded buyer portal | Limited | Standard, hard to change | Your brand, site photos |
| Deployment time | 2 - 3 months | 3 - 4 months | 5 months |
| 5-year cumulative cost (order of magnitude) | EUR 60,000 - 125,000 | EUR 140,000 - 340,000 | EUR 90,000 - 185,000 |
| Code ownership | No | No | Yes |
Above 300 units delivered per year, custom software becomes competitive against per-unit SaaS pricing. Below 100 units, an off-the-shelf package is often the rational choice.
Typical 5-month plan
- Month 1: workshops with sales, sales administration and the technical department, buyer journey mapping, portal mock-ups.
- Months 2 and 3: development of unit inventory, payment calls and the portal, migration of live projects.
- Month 4: options and modifications module, snagging app, connectors.
- Month 5: acceptance testing on a pilot project, team training, portal opening to buyers.
The main risk is data migration: contracts, schedules and options already approved on live projects must be imported without errors, otherwise the portal displays wrong amounts and triggers the opposite of the intended effect.

Layla, sales director at a property developer in Dubai, runs 12 active projects and 400 handovers a year. Her 4-person customer relations team receives around 1,200 calls a month, averaging 8 minutes, which adds up to 160 hours a month.
- With a buyer portal and automatic notifications, the -40% target brings volume down to 720 calls, freeing 64 hours a month.
- At a fully loaded cost of EUR 45 per hour, that is about EUR 34,500 a year.
- Automatically sent and chased payment calls speed up collection by 12 days on average. On EUR 8 million called per year at a 5% financing cost, the gain is about EUR 13,000.
- For an EUR 85,000 project, payback lands around 20 months, excluding the reputational gain with buyers and brokers.
