The verdict in three sentences
A strong specification for an Austin staffing agency runs 15 to 25 pages and states every requirement as something you can test: assignment volume, time to onboard, time to approve a timesheet. It must cover the full cycle from sourcing to onboarding, assignment, timesheet, payroll and invoicing without any re-keying, because that is where gross margin leaks. With a budget of USD 45,000 to 130,000 and a timeline of 3 to 6 months, the precision of this document decides how accurate the quotes you receive will be.
Context to describe first
Developers need to understand your business before they read requirements. Describe your branches (Downtown, North Austin, Round Rock...), your verticals (light industrial, warehouse, events, admin, IT contract), volumes and current tools. US staffing carries specific obligations: Form I-9 must be completed within three business days of the start date, many clients require E-Verify, overtime rules under the FLSA apply above 40 hours a week, and Texas has no state income tax but does have state unemployment tax through the Texas Workforce Commission.
| Context item | Your value | Typical 2026 range |
|---|---|---|
| Branches | ... | 1 to 5 |
| Active temporary workers | ... | 300 to 2,000 |
| Assignments per week | ... | 80 to 400 |
| Client companies | ... | 50 to 500 |
| Internal users | ... | 10 to 50 |
| Current tools | ... | ATS, payroll provider, spreadsheets |
| Budget | ... | USD 45,000 to 130,000 |
| Target go-live | ... | 3 to 6 months |
Measurable functional requirements template
Each requirement should be testable during acceptance. Instead of the system must be fast, write an assignment confirmation is generated in under 2 minutes from a client job order.
| Module | Measurable requirement | Priority |
|---|---|---|
| Sourcing | Search 10,000 candidate records by skill, certification and distance in under 3 seconds | Must have |
| Onboarding | Digital I-9 Section 1 before day one, Section 2 tracked to the 3-business-day deadline, E-Verify case status visible | Must have |
| Assignments | Confirmation generated in under 2 minutes, e-signed, pushed to the worker app | Must have |
| Timesheets | Mobile clock-in or weekly entry, client approval in one click, overtime flagged above 40 hours | Must have |
| Payroll | Export to your payroll provider with zero variance over 3 test cycles, W-2 data complete | Must have |
| Invoicing | Client invoice generated from approved hours with bill rate and markup per client | Must have |
| Client portal | Job orders, assignment tracking, invoice download | Should have |
| Dashboard | Gross margin by client, branch and week | Should have |
Add non-functional requirements: 99.5 % uptime during business hours, US hosting, role-based access to SSNs and I-9 documents, field-level encryption of sensitive identifiers, daily backups with tested restore, and a written incident response plan in line with the Texas data breach notification law.
Timeline and budget split
| Phase | Duration | Share of budget | Deliverable |
|---|---|---|---|
| Discovery and prototypes | 3 to 5 weeks | 10 to 15 % | Approved workflows, clickable prototypes |
| Sourcing, onboarding, assignments | 4 to 6 weeks | 25 to 30 % | Onboarding with I-9 tracking |
| Timesheets and client portal | 3 to 5 weeks | 15 to 20 % | Worker mobile app |
| Payroll export and invoicing | 4 to 6 weeks | 20 to 25 % | Exports validated with your payroll provider |
| Data migration and acceptance | 3 to 4 weeks | 10 to 15 % | Workers and clients migrated, sign-off |
| Go-live and hypercare | 2 weeks | 5 % | Staff training, extended support |
An agency with 400 workers and no client portal sits at the lower end. One with 1,800 workers across 4 branches, a client portal and margin dashboards should plan for USD 100,000 to 130,000 in the US market. A nearshore or offshore studio can bring that down: at Kolonell, a complex web application costs 4,000,000 to 8,000,000 FCFA and up (about EUR 6,100 to 12,200) over 3 to 6 months.

Illustrative example: Marcus owns an independent staffing agency in Austin with 2 branches, 900 active workers and 220 assignments a week. His recruiters re-enter each assignment into the ATS, payroll and invoicing, taking about 10 minutes per assignment. His specification sets a measurable target of 2 minutes. Across 220 assignments that saves about 29 hours a week. At USD 38 per loaded hour, that is roughly USD 1,100 a week, or USD 57,000 a year. A build quoted at USD 95,000 pays back in under two years, before counting billing errors avoided, which he estimates at 0.8 % of revenue.
FAQ
How long should the specification be?
Fifteen to 25 pages for a staffing agency: context, measurable functional requirements, technical requirements and timeline. Beyond 40 pages, vendors skim.
Should we prescribe a technology stack?
No, describe your constraints instead: US hosting, 99.5 % uptime, payroll export format, I-9 retention rules. Let vendors propose the approach and compare at least 3 quotes.
How should I-9 records be handled in the software?
The system must track the 3-business-day deadline, store documents securely and support retention of 3 years after hire or 1 year after termination, whichever is later. Access should be limited to authorised staff and logged.
Can we keep our current payroll provider?
Yes, and that is usually wise: the new tool exports hours and pay codes and the provider runs payroll and tax filings. Plan 3 payroll cycles of parallel running with zero variance before switching off the old process.
How quickly can a first module go live?
Onboarding and assignments can be in production in 8 to 10 weeks. Remaining modules follow in releases, for a total of 3 to 6 months.
