Staffing agency software: run placements, timesheets and pay and bill in one flow

Why do staffing firms need their own kind of software?

Staffing runs at a scale most businesses never see. The American Staffing Association says nearly 2.2 million temporary and contract employees worked for US staffing companies in an average week in 2024. Over the whole of 2023, staffing companies hired 12.7 million temporary and contract employees.

Each worker on assignment creates weekly work for the firm. Someone has to track the hours, run pay and bill the client. A recruitment CRM stops at the hire, so staffing software has to keep going until the assignment ends.

What should staffing agency software do?

Most staffing platforms split into three parts. Firms call them the front office, middle office and back office.

Front office: filling the order

• Job orders: Each client request records the role, rates, shift times, site and start date.
• Candidate pool: You search workers by skill, location, availability and past assignments.
• Fast matching: The system suggests who fits an order, so a recruiter can fill a shift in minutes.

Middle office: from shift to timesheet

• Placement records: Each placement holds the worker, client, pay rate, bill rate and end date.
• Onboarding: Workers complete tax forms and compliance documents on their phones before the first shift.
• Timesheets: Workers clock in on a phone or submit hours, and the client supervisor approves them online.
• Time rules: The system applies overtime, shift differentials and break rules to raw hours.

Back office: pay and bill

• Payroll handoff: Approved hours flow to payroll with the right pay rate, deductions and tax details.
• Client invoices: The same hours become invoices at the bill rate, grouped the way each client wants.
• Margin reports: You see the spread between pay and bill on every placement, client and recruiter.

Which staffing agency software do firms use, and what does it cost?

These details come from each vendor's own pricing page in October 2026. Many staffing tools only quote, so plan time for demos.

Bullhorn

Bullhorn sells to firms of every size. For small agencies, Starter costs $99 per user a month and covers applicant tracking, resume parsing, client records and job posting. Core costs $165 per user a month and adds custom workflows, LinkedIn tools and Bullhorn's app marketplace. Pro and Max add AI search, matching and outreach, and they price by quote. For pay and bill, Bullhorn sells a Middle Office product with timesheets, time rules, invoicing and pay and bill automation. Its Bullhorn One package joins the front office with those tools. Both price by quote. Bullhorn also lists VMS automation that imports jobs from more than 110 vendor management systems, the portals large clients use to send orders.

Crelate

Crelate combines an ATS and a recruiting CRM. Essentials costs $85 per user a month paid yearly, for up to 2 users. Business costs $119 per user a month, billed yearly or monthly, and adds an AI assistant, client portals and reports. Business Plus and Platform are custom priced. For back office links, Crelate sells a data sync service priced on volume and frequency. Its Crelate Hire onboarding tool is priced per hire and adds state and local tax forms.

Avionté

Avionté covers the front office and the back office in one staffing platform. Its site says it handles payroll and billing for complex staffing work, with reporting, a mobile app and an API. Pricing is by demo and quote.

TempWorks

TempWorks pairs an ATS and CRM with back office tools for payroll, invoicing and time management. It also lists W-2 management, tax processing and payroll funding services. Pricing is by demo and quote.

How should timesheets and payroll handoff work?

Errors at the payroll handoff cost staffing firms real money. A wrong pay rate or a missed overtime hour means a worker gets paid wrong or a client gets billed wrong. Fixing either one takes hours. The wider topic of onboarding, time off and payroll handoffs is covered in HR automation.

A clean flow looks like this.

1. The placement sets the rates. The pay rate, bill rate and overtime rules live on the placement record. Nobody retypes them later.
2. Workers submit time on a phone. The app records clock-in and clock-out times or daily hours.
3. The client approves online. The supervisor gets a link, checks the hours and approves them before your cutoff.
4. The system applies the rules. Overtime and shift premiums are worked out from the approved hours.
5. Payroll gets one clean file. Approved hours, rates and deductions go to your payroll system or payroll service.
6. Invoices go out the same day. The same approved hours create the client invoice at the bill rate.

The records also matter for the law. Under the Fair Labor Standards Act, the US Department of Labor says employers must keep payroll records for at least three years. Time cards and other records used to work out wages must be kept for two years. Those records include the hours worked each day, the regular rate and overtime pay. Your software should store each approved timesheet in a form you can pull up quickly.

How long must a staffing agency actually keep timesheets and payroll records?

This splits into two different federal minimums under the Fair Labor Standards Act, and the two get confused often. The underlying time card, the record of when someone actually clocked in and out, only needs two years of retention. The payroll record computed from it, what you actually paid and how, needs three years. Some states set longer periods on top of the federal floor, so check your own state's rules before you rely on the federal minimum alone.

In practice, most staffing firms keep everything, time cards, schedules, payroll registers and pay stubs, for at least three years, and some round up to four so one retention policy also satisfies the IRS's employment tax record requirement. Whatever your software's default retention setting is, do not assume it matches your actual legal obligation, confirm it explicitly rather than finding out during a wage claim or an audit.

What should a staffing firm check before buying?

Ask every vendor to run one of your real placements during the demo, from job order to invoice.

• Your pay rules: Give them a tricky case, such as weekend premiums and overtime across two clients in one week. Watch how the system handles it.
• Your payroll path: Decide if you want payroll inside the platform or a handoff to an outside payroll service. Ask to see the exact export or link.
• Client approval: Approve a timesheet as a client supervisor would. It should take under a minute on a phone.
• VMS orders: If big clients send orders through a vendor management system, ask which ones the platform links to.
• Worker app: Install the worker app yourself. Hard clock-ins lead to late timesheets.
• Total cost: Ask for the yearly price with your recruiter seats, back office users and per-worker fees.

Which AI features help staffing agencies?

AI helps staffing firms most where speed and accuracy pay. These uses are worth testing.

Filling shifts faster

When a client calls for five workers tomorrow, AI ranks available workers by skills, distance and past reliability. It texts the top matches and books the first to confirm. The recruiter checks the list before it goes out. Bullhorn's Max plan lists multi-step AI outreach.

Checking timesheets before payroll

AI scans each week's timesheets before the cutoff. It flags missing punches, hours that look too high and shifts with no client approval. A payroll clerk fixes those few problems and skips checking the rest by hand.

If you use AI to screen or rank candidates, hiring laws apply. My recruitment CRM guide covers NYC Local Law 144 and other AI hiring rules.

When does custom staffing software make sense?

Most staffing firms should buy. Bullhorn, Crelate, Avionté and TempWorks are built for this work. A new or small agency should start with one of them.

A custom build, or a custom layer on top of your platform, is worth a look in these cases.

• Unusual pay rules: You staff healthcare, events or industrial work with rules your platform cannot model.
• Client portals: Large clients want their own view of orders, workers, timesheets and spend. My client portal guide explains the options.
• Payroll gaps: Your ATS and payroll service do not link, so staff rebuild a payroll file by hand each week.
• Worker apps: You want a branded app for shift booking, clock-in and pay stubs.
• Seat fees: Per-user fees across many recruiters cost more each year than the tools you use.

How would Blur Studio approach a staffing firm's software?

I start with one week of payroll. I trace ten placements from job order to timesheet, paycheck and invoice. I mark every step where someone retypes data or chases an approval. If your current platform can fix those steps with better setup, I tell you how. If it cannot, I build the missing piece. That might be a timesheet approval app, an AI agent that checks hours before payroll, or a link between your ATS and your payroll service. The code, the worker records and the accounts belong to you, and I keep the system running after launch.
