The verdict in three sentences
For a 4-branch staffing agency in New York or London with 450 temps on assignment each week, a custom platform costs $60,000 to $135,000 (£45,000 to £100,000) against $1,000 to $3,200 a month for ATS and back-office licences. The return rests on 1.5 admin FTE saved (about $70,000 or £48,000 a year) through e-signed assignment contracts, automated compliance checks and online timesheets that feed payroll and billing directly. Plan 5 to 6 months and a payback of roughly 16 months.
Licences or custom: 2026 comparison
ATS and VMS products are strong on candidate search, but regional networks lose hours on everything in between: chasing timesheets, client approvals, bill rates negotiated client by client, and a dated candidate app.
| Criterion | ATS and back-office licences | Custom platform |
|---|---|---|
| Upfront cost | $6,000 to $18,000 (setup, migration) | $60,000 to $135,000 |
| Recurring cost | $1,000 to $3,200/month by branch and seat | $1,100 to $2,000/month (hosting, support) |
| Assignment contracts | PDF generation, e-signature as add-on | Native e-signature, issue time tracked |
| Timesheets | Keyed by the agency | Entered by the temp, approved by the client in one click |
| Client billing | Standard markups | Markups per client and job category, e-invoicing |
| Candidate app | Generic or missing | Availability, assignments, documents, pay advances |
| VMS integrations | Paid connectors | Beeline or SAP Fieldglass sync built in |
Budget module by module
| Module | Scope | Indicative budget |
|---|---|---|
| Recruiting and talent pool | Resume database, skill and distance matching, candidate app | $12,000 to $27,000 |
| Assignments and onboarding | E-signature, right-to-work or I-9 checks, compliance deadlines | $10,000 to $22,000 |
| Online timesheets | Mobile entry, client approval, overtime and shift premiums | $10,000 to $20,000 |
| Temp payroll | Holiday pay accrual, advances, export to payroll provider | $12,000 to $27,000 |
| Client billing | Negotiated markups, e-invoicing, VMS invoicing | $7,000 to $17,000 |
| Client portal | Job orders, tracking, hours reporting | $5,000 to $12,000 |
| Migration and integrations | Temp and client import, banking, accounting | $4,000 to $10,000 |
Compliance to lock in: in the UK, the Conduct of Employment Agencies Regulations 2003, right-to-work checks, Agency Workers Regulations parity after 12 weeks and holiday pay accrual at 12.07%; in New York, I-9 and E-Verify, the Wage Theft Prevention Act notices and accurate overtime. Data protection runs under UK GDPR or state privacy law.
Where the admin hours go
| Weekly task (450 assignments) | Before | After (2026 estimate) |
|---|---|---|
| Drafting and sending contracts | 12 min each, i.e. 90 h | 3 min, i.e. 22 h |
| Collecting and keying timesheets | 6 min each, i.e. 45 h | Client approval, i.e. 6 h |
| Client billing | 16 h | 3 h |
| Payroll corrections | 8 h | 2 h |
| Chasing client approvals | 6 h | Automatic |
Across 4 branches, about 130 weekly hours are recovered: part moves to sales and temp retention, the rest means 1.5 admin roles do not need replacing.
Mini case study
Rachel, COO of a 4-branch staffing agency in London, pays £1,600 a month in licences, or £19,200 a year. She invests £72,000 in a custom platform, with maintenance at £950 a month (£11,400 a year).
- Licence savings: 19,200 minus 11,400 = £7,800 a year.
- Admin roles not replaced: 1.5 FTE, or £48,000 a year fully loaded.
- Net annual gain: £55,800. Payback: 72,000 / 55,800 = about 16 months.

FAQ
How much does custom staffing agency software cost in 2026?
Budget $60,000 to $135,000 (£45,000 to £100,000) depending on modules and branches, plus $1,100 to $2,000 a month for maintenance. A contracts, timesheets and billing core starts around $60,000.
Are e-signed assignment contracts valid?
Yes, under the US ESIGN Act and UK law an electronic signature is as valid as a handwritten one. It makes issuing terms before the assignment starts simple and auditable.
Do we need to replace our payroll provider?
Not necessarily: the platform can produce pay variables (hours, premiums, holiday pay, advances) and export them to your payroll provider. That cuts $12,000 to $18,000 from the budget.
Can it connect to client VMS platforms?
Yes, integrations with Beeline or SAP Fieldglass sync job orders, timesheets and invoices, removing double entry for enterprise accounts.
How long does the project take?
Plan 5 to 6 months, with a 3 to 4 week pilot in one branch before rolling out to all 4.
