The verdict in three sentences
A custom construction project-tracking system starts at 35,000-65,000 EUR for a field-mobile MVP and reaches 90,000-160,000 EUR as a full platform. ROI comes not from the screens but from early detection of site cost overruns, which recovers 3 to 6 margin points. Offline 3G/4G mode and accounting integration make the difference against per-user/month tools.

Mini case study

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Mr Cazorla, head of a Toulouse construction firm (30 sites/year, 6.5 M EUR revenue), sees average overruns of 4 margin points for lack of real-time tracking of hours and purchases. A mobile MVP at 55,000 EUR (logging + progress + photos) flags variances from week 2 of each site. Recovering just 3 margin points on 6.5 M EUR earns ~195,000 EUR/year; the investment and its maintenance (18,000 EUR/year) pay back in under 4 months. Mobile logging also saves 1.5 staff-days/week of admin re-entry.
FAQ
How much does custom construction tracking software cost in 2026? Budget 35,000-65,000 EUR for a field-mobile MVP and 90,000-160,000 EUR for a full platform, excluding maintenance.
Is offline mode essential on site? Yes, 3G/4G coverage is uneven on sites. Offline mode with deferred sync is built in to guarantee time logging and photos in all conditions.
How does the software improve margin per site? By cross-referencing logged hours, purchases and budget in real time, it flags overruns as they appear, letting you recover 3 to 6 margin points over the year.
Does it integrate with my accounting? Yes, via export or API to your accounting software (6,000-15,000 EUR connector), avoiding double entry of progress statements and purchases.
How long to deploy? 14 to 22 weeks depending on scope, starting with a mobile MVP (logging, photos, progress) rolled out on your first sites.
