The verdict in three sentences
A 6-branch staffing agency placing 450 temps a week in Miami loses more than 2,000 hours a year re-keying paper timesheets, and just as many chances to get payroll wrong. Off-the-shelf staffing software, at 300 to 1,500 USD per branch per month, remains essential for onboarding, compliance and payroll; what is missing is a custom timesheet module and client portal, for 20,000 to 50,000 USD. The decision comes down to three numbers: re-keying hours, the cost of payroll errors and days of invoicing saved.
What staffing software covers, and where it breaks down
US staffing platforms handle the compliance chain well: onboarding, I-9 and E-Verify, W-4, payroll, workers' compensation codes and invoicing. The weak link is almost always the same: capturing the hours actually worked. In construction, logistics, hospitality and events around Miami, timesheets still arrive on paper or as WhatsApp photos, with missing supervisor signatures and badly recorded overtime.
| Step | Market staffing software | Custom module |
|---|---|---|
| Onboarding and e-signature | Covered | Do not rebuild |
| I-9, E-Verify, W-4 | Covered | Do not rebuild |
| Time entry by the temp | Often missing or basic | Mobile app, geofenced clock-in |
| Client approval of hours | Email or paper | Client portal, one-click approval |
| Overtime over 40 hours, night, holiday rates | Calculated at manual entry | Rules per client and per job |
| Transfer to payroll | Re-keyed | Automatic import |
| Client invoicing | After re-keying, day 7 to 10 | On approval, day 1 to 3 |
Federal FLSA rules require overtime at 1.5 times the regular rate beyond 40 hours a week, and wage-and-hour claims are frequent in Florida: every badly recorded hour is legal exposure for the agency.
2026 costs: market tool, custom module or full replacement
The figures below are 2026 market estimates in USD for a 6-branch group. They are not Kolonell prices.
| Item | Staffing software alone | Software + custom module | Full custom staffing platform |
|---|---|---|---|
| Licences (6 branches, 300-1,500 USD per month) | 21,600-108,000 USD a year | 21,600-108,000 USD a year | None |
| Development | 0 | 20,000-50,000 USD | 200,000-400,000 USD |
| Vendor timesheet add-on | 2 to 5 USD per temp per month | Not needed | Included |
| Timeline | Immediate | 3 to 4 months | 12 to 24 months |
| Maintenance | Included | 400-900 USD per month | 3,000-6,000 USD per month |
| Payroll and tax compliance risk | Vendor | Vendor | You |
Rebuilding payroll and tax filings in custom software is a bad idea at this size. The timesheet module, on the other hand, plugs into the existing software's API or imports. On Kolonell's side, this scope falls within the custom application grid: 4,000,000-7,000,000 FCFA (6,100-10,670 EUR) for a simple module, 7,000,000-15,000,000+ FCFA (10,670-22,870+ EUR) with a client portal and multiple rate rules.
What to put in the specification
- Temp app: SMS login, shift start and end, breaks, timesheet photo if the client requires it, offline mode on job sites, English and Spanish.
- Client portal: hours to approve per site, bulk approval, comments, export for the client's cost control.
- Pay rules: overtime, shift differentials, holiday rates, per diem and mileage, by client agreement.
- Integration: import into the staffing software, change log for audits, US hosting and access control.
Mini case study
Daniel, owner of a 6-branch staffing agency in Miami, processes 450 timesheets a week. Re-keying takes about 6 minutes each: 450 x 6 min = 45 hours a week, or 2,115 hours over 47 weeks, at a 35 USD loaded cost: 74,025 USD a year. With 3% of timesheets wrong, he handles 13.5 payroll errors a week, each costing around 40 USD (correction, off-cycle check, admin time): 25,380 USD a year.

On cash, his branches bill about 409,500 USD a week (450 temps x 35 h x 26 USD). Invoicing at day 2 instead of day 8 frees about 351,000 USD of working capital, or 17,550 USD a year of interest saved at 5%.
With a 40,000 USD module and 6,000 USD of annual maintenance, counting only 70% of re-keying and errors removed, the gain net of maintenance reaches about 81,000 USD a year (69,584 USD of re-keying and errors, plus 17,550 USD of cash, minus 6,000 USD). Payback in under 7 months.
FAQ
Will temps really use an app?
Yes, if it fits on two screens and runs on an entry-level smartphone. Adoption usually exceeds 85% after 4 weeks when weekly pay depends on submitting hours.
Does the client portal replace a signed timesheet?
Time-stamped electronic approval by an identified client supervisor is as strong as a paper signature, provided it is logged. It cuts invoice disputes by around 50%.
How long to roll out across 6 branches?
Allow 3 to 4 months: 3 weeks of scoping, 8 to 10 weeks of development, then a one-month pilot with 1 branch and 50 temps before full rollout.
What if we change staffing software later?
The module talks through an isolated connector: switching vendors means rewriting only that connector, 2 to 4 weeks of work.
Is temp workers' data protected?
It is hosted in the US, encrypted and accessed by role. Geolocation is limited to clock-in and clock-out, with retention of 12 months at most.
