The verdict in three sentences
For a New York staffing agency placing 150 to 800 temporary workers per week, custom software costs 40,000 to 100,000 USD in 2026, delivered in 12 to 18 weeks. The main gain is the end of paper and photo timesheets: mobile approval by the client supervisor, automatic overtime rules and direct payroll export. An agency with 300 temps saves about 12 hours of data entry per week and cuts payroll errors by two thirds, errors that are expensive in off-cycle checks and client disputes.
The paper circuit, the first source of cost
Across New York City and the tri-state area, many independent and regional agencies still receive timesheets as text-message photos, emails or paper drop-offs on Friday. A coordinator re-keys everything on Monday, checks overtime, night differentials and spread-of-hours pay, then discovers errors when payroll runs. Each miss means an off-cycle check, an unhappy worker and sometimes a billing dispute with the client.
| Step | Paper circuit | With custom software |
|---|---|---|
| Collecting hours | Photo, email, office drop-off | Mobile entry by worker, one-click client approval |
| Overtime and premiums | Manual, per client rules | Rules per client and NY labor law applied automatically |
| Onboarding (I-9, W-4, NY forms) | Paper packets | Digital onboarding with e-signature |
| Assignment confirmation | Word template, paper signature | Generated, sent and e-signed within hours |
| Payroll export | Re-keyed into payroll | Direct export to ADP, Paychex or Gusto |
| Client invoicing | Spreadsheet then invoicing | Invoices generated from approved hours |
| Processing time (300 temps) | 14 to 16 h per week | 2 to 4 h per week |
Budget, timeline and compliance
The software must support staffing obligations: New York minimum wage (17.00 USD per hour in NYC in 2026), overtime beyond 40 hours, spread-of-hours rules, the NY Wage Theft Prevention Act notices and Paid Sick Leave accrual.
| Module | Indicative 2026 cost (USD) |
|---|---|
| Worker database, skills, certifications | 7,000 - 15,000 |
| Assignments, onboarding and e-signature | 8,000 - 20,000 |
| Mobile timesheets and client approval | 9,000 - 21,000 |
| Rules engine (overtime, sick leave, premiums) | 7,000 - 18,000 |
| Payroll export and invoicing | 5,000 - 15,000 |
| Client portal and dashboard | 4,000 - 11,000 |
| Phase | Duration |
| Scoping, analysis of pay rules and key clients | 2 weeks |
| Worker database and assignments | 3-4 weeks |
| Mobile timesheets and rules engine | 4-6 weeks |
| Payroll export, invoicing, client portal | 2-4 weeks |
| Pilot with 3 clients then rollout | 1-2 weeks |
For recurring costs, plan 15% to 20% of the project per year for maintenance, 250 to 700 USD per month for hosting and about 1 to 2 USD per e-signature depending on the provider.
Mini case study
Thomas runs an agency placing 320 temps per week in Queens, mainly in warehousing and food production. Two coordinators spend 15 hours a week on timesheets and paperwork. He invests 68,000 USD in custom software and 12,000 USD per year in maintenance and hosting. Time drops to 3 hours: 12 hours saved x 48 weeks x 38 USD loaded hourly cost = 21,888 USD per year. Add about 40 off-cycle corrections avoided per month and invoices issued two days earlier, which improves cash flow. Estimated payback is two to three years, faster if the agency opens a second branch without hiring.
FAQ
Need a professional website?

Do workers need to install an app?
No, a web app opened from an SMS link is enough, with no download. Over 90% of workers enter hours on their phone within the first month when approval triggers their pay.
Does the software replace our payroll provider?
No, it prepares clean payroll data and exports it to ADP, Paychex or Gusto. Payroll stays in your current tool, which limits project risk and cost.
How do we handle clients with their own time clocks?
The software imports badge or client portal files in CSV. Each specific connector usually costs 2,000 to 5,000 USD.
Can onboarding forms really be fully digital?
Yes, W-4 and NY state forms are signed electronically, and I-9 uses remote document review where allowed, with each step archived. This reduces audit exposure and speeds up first-day starts.
Wouldn't an off-the-shelf staffing platform be enough?
Standard staffing platforms cost about 6 to 18 USD per active worker per month. For 320 temps, that is 23,000 to 69,000 USD per year, which is why custom software makes sense above 200 weekly placements.
