The verdict in three sentences
A developer selling 1,300 off-plan units across 4 projects in Dubai, at 400 to 900 USD per sq ft, can no longer run inventory, holds, payment plans and escrow reconciliation on spreadsheets shared between sales teams and brokers. Specialised platforms cost 1,500 to 4,000 USD a month and often fit poorly with project-specific payment plans and broker workflows. A custom tool costs 2,500,000 to 15,000,000+ FCFA (3,810 to 22,870+ EUR) at Kolonell depending on complexity, delivered in 12 to 16 weeks, with add-on modules quoted separately.
Why spreadsheets break in off-plan sales
On a 300 to 400 unit tower, in-house agents and dozens of external brokers place holds at the same time, management reprices by floor and view after each sales wave, and finance issues instalment notices tied to construction milestones. With a shared file, errors are inevitable: two buyers on the same unit, an outdated price list, a milestone notice never sent.
| Situation (4 projects, 1,300 units) | Typical frequency, 2026 order of magnitude | Impact |
|---|---|---|
| Double holds on the same unit | 1 to 2 % of reservations | Lost buyer and broker dispute |
| Prices not updated after a repricing | 3 to 5 % of sales | Shortfall of 20 to 60 USD per sq ft |
| Instalment notices sent late | 15 to 25 days average delay | Slower escrow inflows |
| Expired holds not released | 5 to 10 % of stock blocked | Units invisible to brokers |
| Manual management reporting | 1 to 2 days a week | Late pricing decisions |
| Broker commission disputes | 50 to 100 a year | Finance team time |
The costliest issue is cash flow. Under the Dubai escrow framework, buyer payments go into the project escrow account and are released against certified construction progress, so late collections directly delay what the developer can draw.
Market platform or custom tool
Specialised platforms are a solid base, but recurring cost and rigidity weigh on mid-size developers.
| Criterion | Specialised market platform | Custom tool with Kolonell |
|---|---|---|
| Recurring cost | 1,500 to 4,000 USD a month | Maintenance 35,000 to 120,000 FCFA a month (53 to 183 EUR) |
| 5-year cost | 90,000 to 240,000 USD | 3,810 to 22,870+ EUR plus maintenance |
| Dynamic pricing | Often standardised | Rules by floor, view, unit type, phase |
| Payment plans (60/40, post-handover) | Limited configuration | Any plan per project |
| Languages and currencies | Vendor dependent | Set in the quote |
| Data ownership | Vendor | Developer |
The usual scope includes an interactive inventory map showing each unit's status, the pricing engine, the hold, reservation, SPA and Oqood registration cycle, and instalment notices. Inventory and reservations alone sit at the simple level (2,500,000 to 4,000,000 FCFA, or 3,810 to 6,100 EUR). Adding payment plans and a buyer portal brings it to medium (4,000,000 to 7,000,000 FCFA, or 6,100 to 10,670 EUR). The complex level, 7,000,000 to 15,000,000+ FCFA (10,670 to 22,870+ EUR), covers several projects, a broker portal with commission tracking and accounting connectors.
The Dubai framework to build in
Off-plan sales are governed by Law No. 8 of 2007 on escrow accounts and RERA regulations: each project has a dedicated escrow account, units are registered on Oqood with the Dubai Land Department, and broker activity is tied to RERA registration. The tool must mirror these steps, track payments by bank transfer or cheque against the escrow account, flag arrears and keep an audit trail. Buyer data falls under the UAE personal data protection law, so consent, security and retention belong in the specification.
Mini case study
Omar, sales director of a developer with 4 projects in Jumeirah Village Circle and Dubai Creek Harbour, pays a specialised platform 2,500 USD a month, so 30,000 USD a year and 150,000 USD over 5 years. A complex-level custom tool costs at most 22,870 EUR, plus premium maintenance at 183 EUR a month, or 10,980 EUR over 5 years. Total: 33,850 EUR, a saving of well over 100,000 USD over the period.

On cash flow, sending instalment notices 15 days earlier on 32,000,000 USD of outstanding milestone payments, at a 6 % financing cost, is worth about 79,000 USD a year in avoided interest.
FAQ
Can the inventory map be interactive?
Yes, each unit shows its status (available, on hold, reserved, sold) and updates in real time. Across 1,300 units, the view stays fast on mobile for agents at the sales gallery.
How is repricing handled?
The engine applies rules by floor, view, unit type and sales phase. A 30 USD per sq ft increase on a block propagates to every affected unit in seconds.
Are instalment notices automatic?
They are generated as soon as a construction milestone is certified, then sent to buyers. Issuing delays drop from 15 to 25 days to under 2 days.
How long until go-live?
Allow 12 to 16 weeks for the full scope. A first project can switch over from week 10.
Can external brokers place holds?
Yes through a dedicated portal at complex level, which limits their view to released units. Holds expire automatically after the set period, often 48 to 72 hours.
