The verdict in three sentences
Between unrecorded time, forgotten entries and downward rounding, a firm loses on average 5 to 15 % of billable fees. A time-capture and automated-billing tool, priced EUR 12,000 to 35,000 custom, recovers most of that leakage. ROI is measured in weeks once the capture rate rises.
The real problem: time that is never billed
Deferred entry is the enemy of profitability. A lawyer noting tasks on Friday evening forgets 10 to 20 % of what was done. Automation captures time at source.
| Metric | Before tool | After tool | Effect |
|---|---|---|---|
| Time capture rate | 78 % | 95 % | +17 pts |
| Billed hours / lawyer / month | 118 hrs | 138 hrs | +20 hrs |
| Invoice issue time | 22 days | 5 days | -77 % |
| Retainers tracked | manual | automatic | zero misses |
| Fees recovered / yr / lawyer | baseline | +EUR 9,000 | ballpark |
What the tool does, concretely
The software turns each task into a billable line and applies the right hourly rates by fee-earner and matter.
| Function | Description | Gain |
|---|---|---|
| One-click time entry | per-matter timer, mobile included | +15 pts capture |
| Differentiated hourly rates | partner / associate / trainee | fair billing |
| Automated invoicing | generation, VAT, legal mentions | -80 % admin time |
| Retainer management | automatic calls and allocations | smoothed cash flow |
| Overdue reminders | automated sequences | -30 % late payment |
Mini case study
Aoife runs a 6-lawyer firm in Dublin. Each lawyer bills on average 118 hrs/month at EUR 200/hr. Raising the capture rate from 78 % to 95 % adds 20 billed hours per month per lawyer, i.e. EUR 4,000/month/lawyer and EUR 288,000/yr for the team. The custom tool at EUR 24,000, delivered in 10 weeks, pays back in under four weeks of recovered fees. The admin gain (invoices in 5 days instead of 22) also improves cash flow.

How much in fees does a firm really lose?
As a 2026 ballpark, 5 to 15 % of billable fees escape the firm through incomplete capture. On a lawyer billing EUR 280,000, that is EUR 14,000 to 42,000 per year.
Is time-tracking a burden for lawyers?
A good tool makes entry almost invisible: one-click timer, mobile entry, automatic suggestions. The goal is to add zero friction while capturing time at source.
How long to deploy?
Budget 8 to 12 weeks for a scope covering time entry, hourly rates, billing and retainers. Migration of ongoing matters is included.
Does it handle retainers and success fees?
Yes, retainers are called and allocated automatically, and the tool can model blended fees (fixed + success) with threshold tracking.
What ROI should we expect?
For a 6-lawyer firm, the capture-rate lift alone funds the tool within weeks. Annual ROI runs into tens of thousands of euros in recovered fees.
