The verdict in three sentences
For a 6-branch staffing network placing 450 temporary workers a week, a specialised SaaS (80 to 200 EUR per user per month, about 90 to 220 USD) remains the rational choice as long as you have fewer than 20 users and standard processes. Beyond that, custom software at 70,000 to 160,000 EUR (about 77,000 to 175,000 USD) becomes competitive over 5 years and removes vendor lock-in on pricing, data and roadmap. Either way, profitability depends on the assignment contract, timesheet, payroll, invoicing chain: every re-keying step removed is worth more than the licence gap.
The 5-year cost
2026 assumption: 6 branches, 24 users (recruiters, coordinators, payroll, management), 450 temps a week, about 23,000 timesheets a year.
| Item | Vendor staffing SaaS | Custom build |
|---|---|---|
| Subscription or development | 80 to 200 EUR per user per month, i.e. 23,000 to 57,600 EUR a year | 70,000 to 160,000 EUR one-off |
| Setup and worker profile migration | 8,000 to 20,000 EUR | included |
| E-signature of contracts | 0.50 to 1.50 EUR per contract, i.e. 11,000 to 35,000 EUR a year | 0.30 to 0.80 EUR per contract via API |
| Hosting, maintenance, regulatory updates | included | 12,000 to 25,000 EUR a year |
| Cumulative 5-year cost | 180,000 to 480,000 EUR | 190,000 to 420,000 EUR |
| Code and data ownership | data exportable, code not | full |
| Annual price increase | 3 to 8% common | under your control |
Custom software is not automatically cheaper: it becomes attractive when the network grows, when contract volumes surge, or when the vendor cannot handle your specifics (multiple entities, construction, night-shift logistics).
Vendor lock-in: the underestimated risk
| Risk | SaaS | Custom build |
|---|---|---|
| Imposed price increase | high, annual contract | low |
| Vendor acquisition, product change | medium | none |
| Access to raw data | CSV export often limited | your own database |
| Time to deliver a requested feature | 6 to 18 months, if accepted | 2 to 6 weeks |
| Integration with your careers site and CRM | built-in connectors or nothing | tailored |
| Regulatory updates (hiring filings, payroll rates) | handled | must be covered in the maintenance contract |
The last row is the honest trade-off of custom software: legal changes in temporary work (hiring declarations, payroll filings, end-of-assignment and holiday pay rules, ROE and CRA remittances in Canada, DPAE and DSN in France) must be covered by a maintenance contract with committed lead times, or by integrating with a payroll system that handles them.
Typical functional scope
A realistic custom project splits into four blocks. Talent pool and matching: worker profiles, certifications (forklift, driving licence), availability, search by skill and distance. Digital assignment contracts: generated from the client order, e-signed within 2 business days, hiring declaration sent automatically. Timesheets: mobile entry by the worker, client approval, overtime and premium checks. Payroll and invoicing: export to the payroll system and client invoice generated the same day hours are approved. This last block is what frees up cash.
Mini case study
Jason, owner of a 6-branch staffing network across Toronto and the GTA, issues client invoices on average 9 days after week end because approved timesheets arrive late. His weekly revenue is about 230,000 EUR (roughly 250,000 USD). With a tool that cuts this delay to 2 days, he pulls 7 days of revenue into cash, about 230,000 EUR released permanently. His payroll coordinator, who spends 15 hours a week re-keying, recovers 12 hours, about 18,000 EUR a year in loaded cost. Custom software at 120,000 EUR pays back in just over 3 years on time savings alone, and immediately once the released cash is valued at a 6% financing rate.

FAQ
How much does staffing agency software cost in 2026?
A specialised SaaS costs 80 to 200 EUR per user per month, plus 8,000 to 20,000 EUR setup. Custom software ranges from 70,000 to 160,000 EUR, plus 12,000 to 25,000 EUR annual maintenance.
Can custom software file hiring declarations?
Yes, through the official government services for hiring and payroll filings, provided the flow is planned at scoping. Budget 5,000 to 10,000 EUR for this connector.
How long does a custom deployment take?
Between 5 and 8 months for a 6-branch network, with a 4 to 6 week pilot in 1 branch. Contracts and timesheets can ship first, within 3 months.
Can we keep our current payroll software?
Yes, and it is often recommended: the custom tool manages assignments and hours, then exports pay variables to the existing payroll. This cuts the budget by 15 to 25% and reduces regulatory risk.
At what size does custom make sense?
As a 2026 estimate, from 20 users or 300 temps a week, or as soon as you have business needs the vendor refuses to build.
Let's scope your project. Send us your number of branches, users and weekly temps: we will price a scope between 70,000 and 160,000 EUR with a pilot delivered in 3 months. Detailed quote within 48 h. WhatsApp +221 77 596 93 33.
