The verdict in three sentences
A custom professional services billing platform costs between 20,000 and 45,000 EUR in Toronto in 2026. It captures time entry, applies hourly rates by profile, tracks work-in-progress and automates billing, lifting the collection rate by 10 to 20 %. The real gain is not printing invoices but visibility into the profitability of every engagement.
What a time-based billing tool costs in 2026
A 12-consultant Toronto firm compares a generic tool against a custom build. Here are the 2026 orders of magnitude.
| Line item | Generic tool (buy) | Custom (build) |
|---|---|---|
| Upfront cost | 0 EUR (2,500 EUR setup) | 20,000 - 45,000 EUR |
| Licence per user/month | 25 - 60 EUR | 0 EUR |
| Annual cost 12 users | 3,600 - 8,640 EUR | 0 EUR |
| Maintenance / hosting yr | included | 3,000 - 6,500 EUR |
| Bespoke billing rules | limited | included |
| 5-year cumulative | 20,500 - 45,700 EUR | 35,000 - 77,500 EUR |
Here custom is justified less by direct savings than by the collection gain and margin-analysis depth that generic tools struggle to deliver.
Collection and engagement profitability

| Lever | Without a dedicated tool | With custom | Impact |
|---|---|---|---|
| Time logged / billed | 75 - 82 % | 90 - 95 % | +12 pts |
| Collection rate | 80 % | 90 - 96 % | +10 to 20 % |
| Invoice issue delay | 15 - 25 days | 2 - 5 days | -20 days |
| Work-in-progress tracked | manual | automatic | real time |
| Engagement margin view | weak | per engagement | fast decisions |

Mini case study
Sarah, partner at a 12-consultant advisory firm in Toronto. Annual revenue is 1,800,000 EUR. Before the tool, 18 % of delivered time went unbilled for lack of reliable entry. She invests 32,000 EUR plus 4,500 EUR/year maintenance. By raising billed time from 80 to 93 %, the firm recovers roughly 230,000 EUR/year of previously lost fees, an ROI reached within the first quarter of use.
