The verdict in three sentences
A construction and property development SME in Dublin invested 95,000 EUR in 2026 in custom construction management software, and gained 220 hours per month of admin and coordination time. Net ROI was reached in 14 months, with an 18 % reduction in site budget overruns. The real gain is not data entry but real-time visibility over costs and timelines.
The before: the cost of chaos
Before the project, the firm ran 6 simultaneous sites with spreadsheets, messaging apps and paper binders. Hidden costs were everywhere. Here is the costed picture.
| Line | Before (monthly) | Estimated cost EUR/month |
|---|---|---|
| Re-keying & reporting | 140 h | 8,400 |
| Searching scattered info | 55 h | 3,300 |
| Material ordering errors | 4 - 6 incidents | 6,500 |
| Invoicing delays | 12 days average | 5,000 (cash flow) |
| Site budget overruns | +14 % average | variable |
With an average loaded hourly cost of 60 EUR, the 195 unproductive monthly hours represented 11,700 EUR/month, i.e. over 140,000 EUR/year, before even counting material errors and cash-flow delays.
The after: quantified gains
The software centralised quotes, scheduling, cost tracking, supplier orders and invoicing. Each site manager enters data from the site on mobile. Here is the impact measured at 12 months.
| Metric | Before | After | Gain |
|---|---|---|---|
| Admin hours/month | 195 h | 40 h | 220 h saved* |
| Invoicing delay | 12 d | 3 d | -75 % |
| Material errors/month | 5 | 1 | -80 % |
| Average budget overrun | +14 % | +5 % | -9 pts |
| Real-time cost visibility | No | Yes | - |
*The 220 h gain includes coordination and information-search time, not only re-keying. At 60 EUR/hour, this represents 13,200 EUR/month saved, i.e. 158,400 EUR/year.
Mini case study
Karim, manager of this 28-employee SME in Dublin, funded the project at 95,000 EUR (development) plus 14,000 EUR/year of maintenance and hosting. The combined annual gain (time + reduced material errors + fewer overruns) is estimated at 185,000 EUR.
ROI: (95,000 + 14,000) / 185,000 = 0.59 year of cumulative gains to cover the first year, i.e. net ROI reached in month 14 accounting for the gradual ramp-up over the first 4 months. From year 2, the firm frees up around 171,000 EUR/year of net value after maintenance, which it reinvests in two additional sites.

FAQ
How much does custom construction management software cost in Dublin in 2026?
For an SME running 5 to 10 sites, budget 70,000 to 130,000 EUR of development depending on modules (quotes, scheduling, cost tracking, orders, invoicing, site mobile). Maintenance adds 12,000 to 20,000 EUR/year.
How fast is the investment recouped?
In this real case, net ROI was reached in 14 months. The usual range for construction sits between 12 and 20 months depending on site volume and initial disorganisation.
Is mobile essential on site?
Yes, it is the key factor. Real-time entry from the site avoids office re-keying and makes cost tracking reliable. The mobile module represents 8,000 to 16,000 EUR but generates most of the gains.
What cash-flow gain to expect?
By moving from a 12-day to a 3-day invoicing delay, the firm unlocked around 9 days of revenue earlier each month, markedly improving its working capital needs.
Can the software connect to accounting?
Yes, an integration with the accounting tool or an ERP costs 6,000 to 14,000 EUR and removes double entry of invoices and payments, a frequent source of errors.
