The verdict in three sentences
Unbilled-hour leakage is the number-one profitability hole in a law firm. Custom legal billing software at FCFA 5,000,000-12,000,000 (3-6 month lead time) makes time tracking, retainer (trust) monitoring and reminders reliable, with an observed gain of +15% in billed fees. The trade-off turns on the hour leakage that manual billing lets slip every month.
Manual billing vs software
Spreadsheet or paper billing seems cheap, but it lets hours slip and delays collection. 2026 comparison in FCFA.
| Criterion | Manual billing | Custom software |
|---|---|---|
| Entry cost | low | FCFA 5,000,000-12,000,000 |
| Time capture | forgotten, late | continuous, reliable |
| Unbilled hours | 10-15% | 2-4% |
| Retainer / trust tracking | manual | automated |
| Overdue reminders | irregular | scheduled |
| Collection delay | long | reduced |
| Statements and reporting | absent | real time |
The apparent cost of manual billing is low, but the 10-15% fee leakage quickly exceeds the software price.
The unbilled-hour leakage
What this leakage means for a 6-attorney firm. Assumption: hourly rate FCFA 40,000, 120 billable hrs/attorney/month.
| Leakage rate | Lost hours/month (6 attorneys) | Shortfall/month | Per year |
|---|---|---|---|
| 4% | 29 h | FCFA 1,152,000 | FCFA 13,824,000 |
| 8% | 58 h | FCFA 2,304,000 | FCFA 27,648,000 |
| 12% | 86 h | FCFA 3,456,000 | FCFA 41,472,000 |
| 15% | 108 h | FCFA 4,320,000 | FCFA 51,840,000 |
Cutting leakage from 12% to 3% recovers about 9% of fees, i.e. over FCFA 30,000,000/year: software at FCFA 10,000,000 pays off in a few months.
Mini case study
Me Adjovi, partner at a Montreal firm (6 attorneys, commercial litigation), estimates his hour leakage at 12%. He invests FCFA 9,000,000 in custom billing software (time tracking, trust retainers, reminders), plus FCFA 200,000/month maintenance. By cutting leakage to 3%, he recovers about 9% of 120 h x 6 x FCFA 40,000, i.e. FCFA 3,110,000/month. The investment pays off by the third month.
