The verdict in three sentences
A structural engineering firm with 16 engineers tracking projects on spreadsheets discovers overruns too late, once the job is already loss-making. Custom project tracking software costs EUR 20,000 to 40,000 in 2026 (about GBP 17,000 to 34,000 in London) and ships in 10 to 14 weeks. Recovering about 8% of unbilled hours and seeing margin per project pays back the tool within months.
What the tool must track in a reinforced concrete practice
A structural firm bills work split into stages (in the UK, RIBA stages 2 to 6; in France, the MOP law phases) with fixed or percentage-of-works fees, and frequent variations when the project changes.
| Module | Function | Indicative budget |
|---|---|---|
| Project records | Client, developer, stages, fees per stage | EUR 3,000 to 6,000 |
| Timesheets | Weekly time per project and stage, desktop and mobile | EUR 3,000 to 6,000 |
| Budget and alerts | Planned vs used hours, alerts at 80% and 100% of budget | EUR 3,000 to 6,000 |
| Fees and invoicing | Progress invoices, variations, reminders | EUR 4,000 to 8,000 |
| Margin per project | Loaded hourly cost per engineer, real-time margin | EUR 3,000 to 6,000 |
| Resource planning | Load of 16 engineers over 3 months, scheduling trade-offs | EUR 2,000 to 5,000 |
| Accounting connector | Export to Xero, Sage or your accountant | EUR 2,000 to 3,000 |
2026 estimate, order of magnitude. A first batch (projects, time, alerts) goes live in 6 weeks for about EUR 12,000.
Spreadsheet, practice management software or custom
| Criterion | Spreadsheet | Standard practice management software | Custom tool |
|---|---|---|---|
| Upfront cost | EUR 0 | EUR 2,000 to 6,000 (configuration) | EUR 20,000 to 40,000 |
| Annual cost (16 users) | Admin time | EUR 7,700 to 15,400 (EUR 40 to 80/user/month) | EUR 2,500 to 4,500 |
| 5-year cumulative cost | Unquantified, lost hours | EUR 40,000 to 83,000 | EUR 32,500 to 62,500 |
| Stages and variations | Manual | Generic | Native |
| Overrun alerts | No | Basic | Configurable per project |
| Link to your design tools and DMS | No | Rare | Possible |
| Data ownership | Yes | With the vendor | Yes |
Practice management tools are often designed for architects. Custom makes sense when your fee methods and stages do not match the vendor's model.
Measurable gains over 12 months
| Indicator | Before | After 12 months |
|---|---|---|
| Unbilled hours recovered | 0 | 8% of hours produced |
| Projects found over budget after the fact | 1 in 3 | 1 in 10 |
| Delay between stage completion and invoicing | 35 days | 8 days |
| Timesheet entry time per engineer | 45 min per week | 15 min per week |
| Monthly management close | 2 days | 3 hours |
Mini case study
Nick, managing director of a reinforced concrete engineering firm in London, employs 16 engineers producing about 1,500 billable hours each per year, or 24,000 hours. At an average rate of EUR 85 per hour, recovering 8% of unbilled hours (forgotten variations, unpriced extra work) means 1,920 hours, or EUR 163,200 of revenue. Even billing only half of it, the gain exceeds EUR 80,000 a year. With a tool at EUR 30,000 and EUR 3,500 of annual maintenance, payback comes in under 5 months, not counting the cash gained from faster invoicing.

FAQ
Will engineers actually fill in their timesheets?
Yes, if it takes under 15 minutes a week and works on mobile. An automatic Friday reminder pushes completion above 95%.
Does the tool handle percentage-of-works fees?
Yes, fixed fee, percentage, time and materials, and mixed. Variations automatically recalculate the hour budget of the affected stage.
Can we connect our design software and DMS?
Yes, a link to your DMS or project folder structure costs EUR 2,000 to 5,000. A direct link to analysis software is rarely needed.
How long does it take to start?
Allow 6 weeks for batch 1 and 10 to 14 weeks for the full scope. Migrating ongoing projects takes 2 to 3 days.
Where is the data hosted?
In the UK or the EU, with daily backups and UK GDPR compliance. Hosting costs about EUR 50 to 120 per month.
