Staffing Agency Invoice Template: Bill Rate vs Pay Rate

Quick answer: A staffing agency invoice bills a client for temporary or contract workers. It lists each worker, the week worked, regular and overtime hours from approved timesheets, the bill rate for each, the total per worker and the invoice total, plus the client's PO or cost center and payment terms. The pay rate and markup stay internal.

Staffing runs on thin margins and weekly payroll. If invoices go out late or do not match the client's timesheets, you are paying workers out of your own cash for weeks. This guide explains bill rate vs pay rate, how to calculate markup, overtime and conversion fees, and shows a complete weekly staffing invoice with the math.

What is a staffing agency invoice?

A staffing agency invoice is a weekly (sometimes biweekly) bill from a staffing firm to a client business for the hours worked by temporary, contract or temp-to-hire workers placed with that client. The agency is usually the employer of record: it pays wages, withholds taxes and carries workers' compensation, then recovers all of that through the bill rate.

It differs from a standard independent contractor invoice: the workers are agency employees, not freelancers billing for themselves. It is closer to a time and materials invoice, where hours are multiplied by agreed rates.

Bill rate vs pay rate vs markup

Term	Meaning	Example
Pay rate	Hourly wage paid to the worker	$20.00
Burden	Employer taxes, workers' comp, insurance, benefits	About $3.00 (illustrative)
Bill rate	Hourly price charged to the client	$30.00
Markup	(Bill rate minus pay rate) divided by pay rate	50%
Gross margin	(Bill rate minus pay rate minus burden) divided by bill rate	23.3%

Markup and margin are not the same number; confusing them is one of the costliest mistakes new agency owners make. Our markup vs margin guide explains the difference in detail.

How to calculate a staffing bill rate

Start from the pay rate and build up. The federal pieces of the burden are well defined:

• Employer FICA: 7.65% of wages (6.2% Social Security up to the wage base, plus 1.45% Medicare). See the IRS employment taxes overview.
• FUTA: 6.0% on the first $7,000 per employee, usually reduced to an effective 0.6% after the state unemployment credit (less in credit reduction states).
• SUTA: state unemployment tax, rate set by your state and experience.
• Workers' compensation: varies hugely by job class (office work is cheap, warehouse and construction cost more).
• Other: general liability, required paid sick leave, benefits offered or required by law, payroll processing.

Worked example for a $20 per hour warehouse associate (state and comp rates illustrative):

Cost item	Per hour
Pay rate	$20.00
Employer FICA (7.65%)	$1.53
FUTA (0.6%, early in the year)	$0.12
SUTA (illustrative 2.7%)	$0.54
Workers' comp (illustrative $3.00 per $100 payroll)	$0.60
Liability, sick leave, other (illustrative)	$0.40
Loaded cost	$23.19
Bill rate at 50% markup	$30.00
Gross profit per hour	$6.81

From the $6.81 you still pay recruiters, rent, software and bad debts. If the client negotiates you down to a 35% markup ($27.00), gross profit drops to $3.81 an hour. Do this math before quoting.

Overtime, holidays and shift differentials

The Fair Labor Standards Act requires overtime pay of at least 1.5 times the regular rate for non-exempt employees after 40 hours in a workweek (US Department of Labor overtime page), and some states, like California, add daily overtime. Common billing approaches:

1. Bill overtime at 1.5 x the regular bill rate (simple, most common).
2. Apply the markup to the overtime pay rate (cheaper for the client, since burden on overtime is lower than full markup).
3. Bill holiday and shift differential hours at the rates in the contract.

Example weekly staffing invoice

Invoice SA-26-1043 | Keystone Staffing Partners, Columbus, OH | Week ending: Sunday, October 25, 2026 | Issued: October 27, 2026 | Due: November 10, 2026 (net 14)
Client: Midway Distribution Inc. | PO: MD-7781 | Cost center: Warehouse 2

Worker	Position	Hours	Bill rate	Amount
R. Alvarez	Warehouse associate, regular	40.0	$30.00	$1,200.00
R. Alvarez	Warehouse associate, overtime	6.0	$45.00	$270.00
T. Nguyen	Warehouse associate, regular	38.5	$30.00	$1,155.00
K. Brooks	Forklift operator, regular	40.0	$33.00	$1,320.00
K. Brooks	Forklift operator, overtime	4.5	$49.50	$222.75
D. Price	Shift lead, second shift, regular (incl. $1.00 differential)	40.0	$35.00	$1,400.00
Total due (169.0 hours)				$5,567.75

Notes: Timesheets approved by J. Ortiz (Midway) on October 26, 2026, attached. Temp-to-hire conversion terms per Master Services Agreement section 6. Overtime billed at 1.5 x bill rate.

The math: 158.5 regular hours plus 10.5 overtime hours equals 169.0 hours. Overtime bill rates are 1.5 x the regular bill rate ($30.00 x 1.5 = $45.00; $33.00 x 1.5 = $49.50). Pay rates do not appear anywhere on the invoice.

How to invoice staffing clients step by step

1. Sign a master services agreement covering bill rates, overtime method, payment terms, conversion fees and timesheet approval.
2. Collect approved timesheets weekly. Use a timesheet template or the client's VMS.
3. Reconcile hours against payroll before invoicing; they must match.
4. Split regular, overtime and differential hours into separate lines per worker.
5. Add client references (PO, cost center, department).
6. Invoice within a day or two of week end using the free invoice generator, numbered with the invoice number generator.
7. Track receivables weekly. Payroll does not wait; see cash flow management and factoring vs invoice discounting if you need to bridge the gap.

Conversion fees and direct hire

When a client hires your temp directly, bill the conversion fee on its own invoice referencing the contract clause. Many agreements waive or reduce the fee after a set number of hours. Direct-hire placements (no temp period) are usually billed as a percentage of the first-year salary, with a guarantee period; invoice those separately, like a commission invoice.

Vendor management systems and MSP programs

Larger clients often buy staffing through a vendor management system (VMS) or a managed service provider (MSP). In those programs:

• Workers enter time in the VMS, and the client approves it there.
• The VMS generates invoices or a consolidated bill from approved time, and your own invoice may only be a supporting document.
• The MSP or VMS operator typically deducts a fee from your bill rate, so the amount you receive is less than the rate shown.
• Rate changes, overtime approvals and extensions must be entered in the system before the work, or they will not be paid.

Reconcile what the VMS paid against your payroll every week. Short payments from unapproved hours or missing overtime approvals are common and easy to lose track of.

Cost-plus vs bill-rate pricing

Most staffing invoices use a single bill rate. Some clients, often in government or large contracts, prefer a cost-plus model, where the invoice shows the worker's pay plus burden plus a fixed fee or percentage.

Model	What the client sees	Pros	Cons
Bill rate	One hourly price per worker	Simple, protects your margin details	Client cannot see cost changes, so rate increases need negotiation
Cost-plus	Pay rate, burden, fee	Transparent, passes tax increases through automatically	Exposes your costs, more reconciliation work
Fixed fee per placement	One fee for a defined project	Easy budgeting for the client	Risk of overruns falls on the agency

Whatever you choose, include a clause allowing rate adjustments when statutory costs change, such as minimum wage increases, new paid leave laws or higher state unemployment rates. Those changes can wipe out a thin margin halfway through a contract.

Common staffing invoice mistakes

• Invoicing unapproved hours, which leads to short payments.
• Mixing up markup and margin when quoting.
• Billing overtime at the regular rate because the contract was silent.
• Showing pay rates on the client invoice when the agreement uses bill rates only.
• Late weekly invoices that stretch your payroll float.
• Missing PO or cost center, so the client's AP team cannot route the bill.

Payment terms, cash flow and funding payroll

The core cash flow problem in staffing is timing: you pay workers every week, but clients pay in 15, 30 or 45 days. A $5,000 weekly invoice on net 30 means you fund four to five weeks of that client's payroll yourself before the first payment arrives.

Ways agencies manage this:

• Shorter terms for small clients, such as net 7 or net 15, written into the MSA.
• Credit checks and credit limits per client before placing workers.
• Payroll funding or factoring, where a funder advances most of each invoice's value for a fee.
• A business line of credit sized to a few weeks of payroll; see how a business line of credit works.
• Fast invoicing: invoices out the day after the workweek closes, not at the end of the month.
• Late fees as allowed by the contract, applied consistently.

Staffing invoice checklist

1. Week ending date and client references (PO, cost center, department) are shown.
2. Every line matches an approved timesheet.
3. Regular, overtime, holiday and differential hours are on separate lines.
4. Bill rates match the current rate sheet for each position.
5. Total hours on the invoice equal total hours in payroll for that client.
6. Conversion or direct-hire fees are on their own invoice.
7. Payment terms and remittance details are printed.
