The verdict in three sentences
For a Dubai construction SME, vertical SaaS (50-110 USD/user/mo) quickly covers estimating and invoicing but stays rigid on per-project cost tracking and progress claims. Custom software (55 000 to 120 000 USD) is justified once you run several concurrent projects with subcontractors, timesheets and margins to steer in real time. The real gain is not the software price: it is the project margin recovered by catching overruns before they cost you.
Build vs buy: the numbers
Construction vendors bill per user per month. Custom is a one-off build plus maintenance. 2026 orders of magnitude for an SME of 15 to 25 users.
| Criterion | Vertical SaaS | Custom |
|---|---|---|
| Upfront cost | 0 to 5 000 USD (setup) | 55 000 to 120 000 USD |
| Monthly cost | 50 to 110 USD/user | Maintenance 15 %/yr of build |
| Time to go live | 3 to 8 weeks | 4 to 6 months |
| Per-project cost tracking | standard | fully custom |
| Timesheets and subcontractors | optional module | integrated |
| Code ownership | no | yes |
| Accounting/payroll integration | connectors | custom |
For 20 users, a vertical runs 12 000 to 26 400 USD/yr, or 36 000 to 79 000 USD over 3 years. Custom becomes competitive once scope exceeds standard functions.
The functional scope to price
Useful construction software steers money, not just schedules. 2026 orders of magnitude for custom effort.
| Module | Effort (days) | Indicative cost (USD) |
|---|---|---|
| Estimating and price library | 15 to 22 | 10 500 to 15 400 |
| Per-project cost tracking | 18 to 28 | 12 600 to 19 600 |
| Progress claims | 12 to 18 | 8 400 to 12 600 |
| Timesheets and hours | 10 to 15 | 7 000 to 10 500 |
| Subcontractor management | 10 to 16 | 7 000 to 11 200 |
| Margin dashboard | 8 to 12 | 5 600 to 8 400 |
| Field mobile app | 15 to 22 | 10 500 to 15 400 |
The per-project cost tracking module is the core of ROI: it turns an invisible budget gap into an actionable alert.
Mini case study
Karim, owner of a structural works SME in Dubai (22 staff, 9 active projects), invests 82 000 USD in custom software plus 12 300 USD/yr maintenance. Previously overruns surfaced at closeout, too late. After 6 months: overruns are caught in real time and average project margin rises by 5 points. On 5.1M USD of annual works, that is 255 000 USD of extra margin. Each site manager saves 10 h/mo on data entry and reporting. Payback is reached in 18 months, even including maintenance.

FAQ
Do we have to drop our existing vertical tool for custom?
Not necessarily. Many SMEs keep the vertical for compliant invoicing and layer a custom cost-tracking module on top, via export or API. Budget 7 000 to 14 000 USD for the integration.
How long for a first usable version?
An MVP focused on estimating and cost tracking ships in 3 to 4 months. Full scope (timesheets, subcontractors, mobile) takes 4 to 6 months.
Is the field mobile app essential?
Yes for timesheets and field updates. Without it, entry stays at the office with a lag. Mobile costs 10 500 to 15 400 USD but feeds cost tracking in real time.
How is ROI calculated?
Mainly through recovered project margin (overrun detection) and admin time saved. A gain of 3 to 5 margin points on multi-million volume easily covers the build.
What annual maintenance should we plan?
Maintenance of about 15 %/yr of build cost, or 8 250 to 18 000 USD/yr for a 55 000-120 000 USD project. It covers enhancements, fixes and support.
