The verdict in three sentences
An off-the-shelf construction management software starts at 30-80 EUR per user per month, which is enough for a company that only wants to centralise time tracking and reports. As soon as you need to connect purchasing, budget tracking and payroll, or run several sites at once with your own rules, custom software (45,000 to 100,000 EUR) becomes profitable. The return doesn't come from the licence saved but from reducing cost overruns, which often represent 5 to 15 % of a project's value.
Off-the-shelf vs custom: what you really pay
A SaaS solution is billed per user: fast to deploy, but the cost climbs with field headcount and you stay locked into its data model. Custom is an upfront investment amortised over 4 to 6 years that fits your processes (contracts, progress billing, retention guarantees).
| Item | Off-the-shelf (SaaS) | Custom software |
|---|---|---|
| Entry cost | 0 to 3,000 EUR (setup) | 45,000 to 100,000 EUR |
| Recurring cost | 30 to 80 EUR/user/month | Hosting 150 to 500 EUR/month |
| Deployment | 2 to 6 weeks | 3 to 6 months |
| Field mobile module | Standard, not editable | Tailored to your forms |
| Budget tracking | Generic | Your cost codes |
| Code ownership | No | Yes |
| Cost at 30 users / 4 years | ~115,000 to 150,000 EUR | ~70,000 to 120,000 EUR |
The modules that drive ROI
Not all modules carry the same weight. Real-time budget tracking and mobile time entry are the ones that directly cut overruns and end-of-project disputes.
| Module | Main benefit | Estimated 2026 impact |
|---|---|---|
| Mobile field time tracking | No more hours lost on paper | +3 to 5 % labour margin |
| Live budget tracking | Overrun alert before billing | -10 to 20 % overruns |
| Purchasing management | Order / delivery matching | -5 to 8 % on materials |
| Reports & photo snags | Enforceable proof, fewer disputes | 2 to 4 h/week saved |
| Progress billing | Faster invoicing | -15 days collection delay |
| Multi-site planning | Better crew allocation | +1 site managed per supervisor |
Mini case study
Thomas runs a 45-employee structural works firm near Bordeaux, with 6 concurrent sites and 7.2M EUR revenue. His average overruns hover around 9 % of the works budget, roughly 300,000 EUR of margin lost per year. He invests 78,000 EUR in custom software (time tracking, purchasing, budget monitoring). By bringing overruns from 9 % to 6 %, he recovers nearly 100,000 EUR in the first year: the tool pays for itself in under 10 months, excluding administrative time savings estimated at 6 h/week per site supervisor.

How much does construction management software really cost in 2026?
From 30 to 80 EUR/user/month in SaaS, or 45,000 to 100,000 EUR for custom. Above 25-30 field users, custom is often cheaper over 4 years.
SaaS or custom: which should I choose?
SaaS if your processes are standard and headcount stable. Custom if you handle public contracts, retention guarantees or specific cost accounting that generic tools don't cover.
How long does deployment take?
Expect 2 to 6 weeks for an off-the-shelf solution and 3 to 6 months for custom development, including data migration and team training.
Does the mobile module work without a network on site?
Yes: a good tool includes an offline mode that syncs once the network returns. It's essential on rural or underground sites.
What ROI can I realistically expect?
Cutting overruns by 10 to 20 % is the main lever. On a 500,000 EUR project, saving 3 points means 15,000 EUR recovered per site.
