The verdict in three sentences
A law firm moving from spreadsheet time tracking to custom software for time entry and billing recovers on average 11 hours/week on invoice production alone. The real financial gain lies elsewhere: +12% of hours actually billed, because time stops "evaporating" between the work and the invoice. With a USD 63,000 build and USD 1,000/month maintenance, break-even lands around 24 months — and holds afterward as net gain.
Before / after: the real numbers
The firm, 9 lawyers and 3 assistants, billed by time spent but lost hours in the entry → validation → invoice chain. Here is the before/after on key indicators.
| Indicator | Before (spreadsheet) | After (custom software) |
|---|---|---|
| Hours entered/billed | baseline | +12% |
| Invoice production time | ~15 h/week | ~4 h/week |
| Average collection time | 58 days | 41 days |
| Unpaid invoice rate | baseline | -40% |
| Billing errors | frequent | rare (auto checks) |
| Work-in-progress visibility per file | poor | real time |
The client portal — invoice access, payment schedule, online payment — explains most of the drop in unpaid invoices and collection time.
The structure of the investment
The budget splits between build, light history migration and maintenance. In Toronto, at a USD 680/day rate, here is the 2026 order of magnitude.
| Line item | 2026 amount (USD) | Nature |
|---|---|---|
| Custom software build | 63,000 | Time, billing, portal |
| Clients & files migration | 4,900 | Structured import |
| Training (9 + 3 seats) | 4,100 | 2 sessions |
| Maintenance | 1,000 / month | Fixes + enhancements |
| Hosting + backups | 200 / month | Managed cloud |
Over 24 months, total investment (build + maintenance + hosting) is around USD 91,000 — covered by the billed-hours gain alone.

Mini case study
Mr. Fraser, managing partner of the Toronto firm, quantifies the return. The 9 lawyers bill on average 1,500 billable hours/year. A 12% gain equals ≈ 1,620 additional hours/year for the firm. At an average USD 195/hour, that is ≈ USD 315,900/year of potential additional billing — part of which is time previously lost. Even conservatively counting a third as actually collected, the software (USD 63,000 + 24 × USD 1,000 maintenance) pays back well before the theoretical 24 months. The 11 hours/week freed on billing are redeployed to legal work.
FAQ
Where does the +12% billed-hours gain come from? From real-time entry: time is captured at the moment of the work, not reconstructed at month-end. Fewer omissions, less underestimation, more hours actually reaching the invoice.
Does the client portal really cut unpaid invoices? Yes: in this case, -40% unpaid and 17 days gained on collection. Online invoice access and integrated payment remove manual follow-ups.
How long to go live? Budget 12 to 16 weeks for a time + billing + portal scope, training included.
Why custom rather than an off-the-shelf legaltech? When the billing logic (fixed fees, retainers, success fees) falls outside the standard, a vertical forces costly workarounds. A USD 63,000 build is justified as soon as those specifics weigh on margin.
What is the real break-even? 24 months on a conservative build + maintenance calculation. Counting the recovered billed hours, most firms reach it in 12 to 16 months.
