HR consulting firm management software cost in Berlin in 2026

The verdict in three sentences

A custom management platform for an HR consulting firm costs between 40,000 and 85,000 EUR depending on consultant numbers and billing-model complexity. ROI reads in admin hours saved: staffing, capacity planning, timesheets and billing stop being keyed into scattered spreadsheets. Budget 5 to 6 months for a fully operational tool.

What an HR consulting platform must orchestrate

A consulting firm lives on the right allocation of consultants to engagements. That means continuously managing four blocks: staffing and capacity planning (who's available, on what, at what utilization), timesheets (time per engagement), billing (fixed fee or time and materials), and profitability tracking per engagement and per consultant.

Generic tools (market ERP, PSA) exist but often impose their billing logic. Custom makes sense when the firm mixes fixed fee, T&M and retainer, handles subcontracting, or wants a visual capacity plan tailored to its organization.

Custom vs. market PSA: the comparison

For a 25-consultant firm, a PSA at 30 EUR/user/month is 9,000 EUR per year in subscription, i.e. 45,000 EUR over 5 years, with the vendor's customization constraints. Custom becomes relevant once the firm passes 20-25 consultants and its billing models don't fit the standard tool.

Mini case study

Antoine, partner of an HR consulting firm in Berlin (28 consultants, mixed fixed-fee/T&M billing), sees his back-office team spend roughly 3 hours per consultant per month consolidating timesheets and billing in spreadsheets, i.e. 84 hours monthly. He invests 62,000 EUR in custom management software covering staffing, timesheet and billing.

Automation cuts that time by 70 %, roughly 59 hours saved per month, or 708 hours per year. Valued at a loaded cost of 45 EUR/hour, that's about 31,800 EUR of admin time freed per year, before counting fewer billing delays that improve cash flow. The tool pays back in about 2 years, even before utilization gains.

FAQ

Can we handle both fixed fee and T&M? Yes, that's precisely one of the arguments for custom. The billing module handles fixed-fee, time-and-materials or retainer engagements, with different rules per contract.

Does the capacity plan prevent over-allocation? Yes. Visual staffing shows each consultant's utilization and alerts on over-allocation or under-load, improving the firm's average utilization rate.

Can consultants enter time on mobile? Yes, the timesheet is available responsive or as a PWA. Quick end-of-day entry improves data reliability and therefore T&M billing.

What annual maintenance budget should we plan? Budget a ballpark of 9,000 to 15,000 EUR per year for a 60,000-85,000 EUR project, covering hosting, enhancements, fixes and support.

Can we integrate accounting and payroll? Yes, via API or export to your accounting software and payroll tool. This integration is a ballpark of 4,000 to 7,000 EUR depending on the systems.
