The verdict in three sentences
A construction or property-development firm in Dublin has three options: vendor licence, subscription vertical SaaS, or custom development. For fewer than 3 concurrent sites, vertical SaaS (from EUR 5,300/yr) is the most rational; above 5 sites, with a need for fine budget tracking, custom (EUR 21,000 to 33,000) becomes cheaper from year 3. What truly makes the difference is the 3-year total cost of ownership and the ability to track site costs in real time.
The modules that matter in site management
Useful construction software covers estimating/quoting, per-site budget tracking (direct cost, margin), procurement and equipment management, crew time tracking, and progress-billing of works. For property development, you add commercial tracking of units and the drawdown schedule.
| Module | Construction value | Complexity | Custom budget EUR |
|---|---|---|---|
| Quantitative estimating / quoting | Critical | High | 5,300 - 7,600 |
| Per-site budget tracking | Critical | High | 6,100 - 9,100 |
| Procurement + equipment | High | Medium | 3,800 - 6,100 |
| Crew / subcontractor time tracking | High | Medium | 3,000 - 5,300 |
| Progress-billing of works | Critical | Medium | 3,800 - 6,100 |
| Unit sales tracking (development) | Optional | Medium | 3,000 - 5,300 |
| Full-scope total | — | — | 25,000 - 39,500 |
Comparison of the three options and 3-year TCO
The figures are a 2026 order of magnitude in EUR for a 25-employee firm managing 4-6 sites in Dublin.
| Item | Vendor licence | Vertical SaaS | Custom |
|---|---|---|---|
| Acquisition / initial dev | EUR 12,200 | 0 | EUR 27,400 |
| Subscription yr 1 | EUR 2,300 (maintenance) | EUR 6,400 | 0 |
| Setup / training | EUR 3,800 | EUR 2,700 | included |
| Subscription yr 2 | EUR 2,300 | EUR 6,400 | 0 |
| Subscription yr 3 | EUR 2,300 | EUR 6,400 | 0 |
| Maintenance / evolutions yr 2-3 | included | included | EUR 8,200 (15 %/yr) |
| Hosting 3 years | EUR 1,400 | included | EUR 2,700 |
| 3-year TCO | EUR 24,900 | EUR 28,300 | EUR 38,300 |
Over 3 years, the vendor licence looks cheapest, but it often caps out on features and user count. Custom costs more upfront but, from year 4, its recurring costs (~EUR 3,700/yr) stay well below SaaS (EUR 6,400/yr and rising as sites grow). Over 5 years, custom drops back below SaaS.

Karim, director of a 30-employee construction firm in Dublin, 6 active sites. He pays EUR 7,300/yr for SaaS and loses margin for lack of fine budget tracking: on his last site, an undetected cost overrun cost EUR 10,700. He invests EUR 29,000 in a custom build with real-time budget tracking and overrun alerts.
Maths: he saves EUR 7,300/yr in SaaS and, above all, real-time tracking prevents at least one overrun a year in the EUR 7,600 to 12,200 range. Prudent annual gain: ~EUR 15,000. The custom build repays in 24 months, then generates over EUR 14,000/yr net gain. Over 5 years: +EUR 40,000.
FAQ
How much does construction site management software cost in Dublin in 2026? From EUR 5,300/yr in vertical SaaS to EUR 25,000 - 39,500 in full custom. The price depends on the number of concurrent sites and the budget-tracking modules.
SaaS or custom? Below 3 concurrent sites, SaaS is enough. Above 5 sites, with a fine-margin need, custom becomes cheaper from year 3-4.
Which module pays back fastest? Per-site budget tracking: catching a single cost overrun (often EUR 7,600 and up) repays a large part of the project.
What implementation timelines? A targeted scope (estimating + budget tracking) ships in 10 to 14 weeks; a full scope in 18 to 24 weeks, site-manager training included.
Does field time tracking work without good connectivity? Yes, we build an offline mode with deferred sync, essential on poorly covered sites. Budget EUR 2,300 to 3,800 for that module.
