The verdict in three sentences
Custom PSA (professional services automation) software for a consulting firm ranges from 45 000 to 125 000 EUR in 2026, depending on staffing depth and margin steering. The ROI lever is consultant utilization: every point gained translates directly into margin. Budget 4 to 6 months for an engagements + timesheet + profitability foundation.
PSA module pricing in 2026
A firm of 15 to 80 consultants needs to steer staffing and margin in real time. Here are the 2026 ranges.
| Module | Indicative price 2026 (EUR) | Timeline | Main gain |
|---|---|---|---|
| Engagement & project management | 11 000 - 23 000 | 4-6 wks | Centralized project view |
| Timesheet & time entry | 9 000 - 18 000 | 3-5 wks | Reliable billable time |
| Staffing & capacity planning | 12 000 - 28 000 | 5-8 wks | Optimized utilization |
| Margin & project profitability | 11 000 - 24 000 | 4-7 wks | Live margin visibility |
| Fixed-price / T&M billing | 9 000 - 19 000 | 4-6 wks | Leak-free billing |
| Executive dashboards | 8 000 - 17 000 | 3-5 wks | Data-driven decisions |
A Starter foundation (engagements + timesheet + billing) fits in 45 000 - 62 000 EUR. With advanced staffing and full margin steering, it climbs toward 105 000 - 125 000 EUR.
The crux: utilization rate
In consulting, profitability hinges on the share of billable time. A well-built PSA makes that number visible and actionable.
| Metric | Without PSA | With custom PSA | Effect |
|---|---|---|---|
| Average utilization | 68 % | 76 % | +8 pts |
| Forgotten billable time | 6 % | 1.5 % | Revenue recovery |
| Billing delay | 25 days | 8 days | -17 days |
| Average net margin / project | 18 % | 24 % | +6 pts |
| Reporting hours / month | 40 h | 12 h | -28 h |
Mini case study
Éric, partner at a 40-consultant firm in Lyon, bills an average day rate of 900 EUR over 210 working days per consultant. At 68 % utilization, each consultant bills 143 days, i.e. 128 700 EUR. A custom PSA at 74 000 EUR lifts utilization to 76 %, adding 16 billable days per consultant: 14 400 EUR of additional revenue per head. Across 40 consultants that is 576 000 EUR of extra annual revenue. The investment pays for itself in under two months.

Won't a generic ERP do the job?
An ERP handles accounting, not the granularity of staffing or real-time margin per engagement. Custom PSA fits your model (fixed-price, T&M, mixed) and eliminates parallel spreadsheets.
How do you get reliable time entry?
By making the timesheet simple (mobile, pre-filled from the schedule) and tying it to billing. When entry drives payroll and invoicing, completion exceeds 95 %.
Is staffing really automatable?
The tool doesn't decide for you, but it shows availability, skills and capacity conflicts. Manual staffing drops from several hours to a few minutes per week.
Can we track margin in real time?
Yes: logged time, loaded costs and billing feed a continuously updated per-project margin. You catch a slipping project before it gets expensive.
How long to deploy?
4 to 6 months for a full foundation. An engagements + timesheet module can ship in 8 weeks to quickly make billing reliable.
