The verdict in three sentences
For a Dubai developer handing over 1,200 units a year across 6 projects, a custom snagging and handover platform costs between AED 140,000 and 320,000 (about USD 38,000 to 87,000) in 2026. It replaces spreadsheets and WhatsApp photos with snags photographed and pinned on floor plans, assigned directly to subcontractors, plus a buyer portal to track their closure. A realistic target is cutting snag closure time from 90 to 30 days, for a 4 to 6 month project.
What the current mess costs
At a developer this size, every unit handed over carries 8 to 15 snags on average (paint, joinery, MEP, tiling). Across 1,200 units, that is 10,000 to 18,000 snags a year, tracked in project spreadsheets and WhatsApp groups with site engineers. Subcontractors dispute, buyers chase, and retention money stays locked.
| Indicator | Spreadsheets and WhatsApp | Snagging platform |
|---|---|---|
| Snags per year | 10,000 to 18,000 | 10,000 to 18,000 |
| Average closure time | 90 days | 30 days targeted |
| Snags disputed by subcontractors | 15 to 25 % | Under 5 %, dated photo evidence |
| Buyer calls to customer service | 600 to 900 per month | Cut by 3 with the portal |
| Handover preparation per unit | 2 to 3 h | 45 min |
| Management visibility | Monthly project review | Real-time dashboard |
These 2026 orders of magnitude come from comparable projects in the Gulf and North Africa.
Scope and price
| Building block | Content | Indicative budget |
|---|---|---|
| Mobile inspection app | Photo, pin on plan, category, offline on site | AED 32,000 to 72,000 |
| Plans and units | PDF plan import by floor, units, typologies | AED 16,000 to 36,000 |
| Subcontractor assignment | Notifications, contractual deadlines, proof of closure | AED 24,000 to 56,000 |
| Buyer portal | Snag tracking, appointment booking, handover sign-off | AED 28,000 to 64,000 |
| Key handover and inspection report | Checklist, meter readings, e-signature | AED 16,000 to 36,000 |
| Management dashboards | Delays by project, unit and subcontractor | AED 12,000 to 28,000 |
| Hosting, security, training | UAE hosting, backups, site team training | AED 12,000 to 28,000 |
Total: AED 140,000 to 320,000. Annual maintenance around 15 %, so AED 20,000 to 48,000.
Custom vs off-the-shelf app
| Criterion | International SaaS | Custom build |
|---|---|---|
| Annual cost for 40 users | AED 60,000 to 120,000 | AED 20,000 to 48,000 maintenance |
| 5-year cost | AED 300,000 to 600,000 | AED 240,000 to 560,000 |
| Buyer portal in English and Arabic | Rare or add-on | Included |
| Integration with sales CRM and ERP | Limited | Tailored |
| Time to start | 1 to 2 months | 4 to 6 months |
| Ownership of data and code | No | Yes |
SaaS suits a developer handing over fewer than 300 units a year. Above that, the buyer portal and ERP integration tip the balance towards custom.

FAQ
Does the app work without signal on site?
Yes, inspection works offline and syncs as soon as a network is available. A tablet can hold over 500 snags with photos before syncing.
Do subcontractors need a licence?
No, they access their snags through a secure link or a free app. A developer this size works with 40 to 80 subcontractors at no extra cost.
Is the handover report legally robust?
Timestamped e-signature with photos produces an enforceable record aligned with UAE electronic transactions law. The PDF is archived and sent to the buyer within 5 minutes.
Can we start on a single project?
Yes, a 6 to 8 week pilot on a 200-unit project is recommended before rolling out to the other 5.
Is the portal available in Arabic?
The buyer portal ships in English and Arabic with full right-to-left support, for about AED 12,000 extra.
