Temp Staffing Payroll Software: Timesheets, Pay Runs and AI Features

Payroll software for temps should attach every timesheet to an assignment with its own pay rate, bill rate and client approver, then show exceptions before the pay run is released. AI can already chase missing hours, flag odd entries and draft a run for review; it should not approve pay or calculate deductions for you.

Ordinary payroll assumes one person, one job and one rate. A temp may work two assignments for two clients in the same week, each with its own pay rate, its own bill rate and a supervisor who has to sign the hours. That structure, not the payslip, is where small agencies lose money, so it is the first thing to test in any demo.

For this comparison I read the public pages of six products in November 2026: three staffing suites (TempWorks, Avionté and Bullhorn), two shift and time products that hand approved hours to a payroll provider (Deputy and Ubeya) and one general payroll product with time tracking (QuickBooks Workforce). Prices are published list prices before tax. Where a vendor publishes none, I say so instead of guessing.

On AI, the three staffing suites describe recruiting-side features, and none names a timesheet or pay-run feature on its public pages. The clearest pay-run features I found sit in Deputy and QuickBooks. Everything else you can do yourself with a chat assistant and an anonymised export, which the pay-run section below walks through.

Why one worker can break ordinary payroll software

Five things separate temp payroll from a normal run, and each maps to a feature a vendor can show you in ten minutes.

1. Rates belong to the assignment. The same worker can earn one rate at a warehouse client from Monday to Wednesday and another at an office client on Thursday and Friday. Software that keeps a single rate on the worker's record pays and bills one of those stints wrongly.
2. Hours need a second signature. The client's supervisor confirms the hours, not only the worker. Without an approval step inside the product, that confirmation lives in email threads and phone photographs, and someone re-keys it.
3. The same hours create two money flows. Wages go out and an invoice goes to the client. The gap between them, less employer on-costs, is your margin, so the product should show pay and bill side by side for every assignment.
4. Workers start and leave within weeks. Each starter needs bank details, tax declarations and eligibility documents captured once and correctly, and each leaver needs a clean final pay.
5. The cash gap is built in. Temps are paid weekly while clients pay on their own terms, often 30 days or more. That is a funding decision rather than a software feature, though TempWorks lists payroll funding among its services.

Here is the first point in money. A temp works 24 hours for a warehouse client (paid $19.50 an hour, billed at $26.00) and 16 hours for an office client (paid $22.00, billed at $27.50) in one week. Wages are 24 × $19.50 + 16 × $22.00 = $820, and the two invoices total 24 × $26.00 + 16 × $27.50 = $1,064. That is a gross margin of $244 before on-costs, or 22.9% of billings. If the system applied the office rates to all 40 hours, wages would be $880 and the invoice $1,100: $60 overpaid to the worker and $36 over-billed to a client who will query it. All figures are illustrative.

Twelve requirements, each with a demo test

Ask the vendor to run each test live in a trial or demo account rather than describe it. Write down what you saw, because three weeks later the sales calls blur together.

Rows 1, 3 and 6 decide most cases. A product that fails on assignment-level rates or client approval pushes the work back into spreadsheets, and no feature list makes up for that.

Six products and what their public pages say

The table lists what each vendor publishes, not how well the product works. I did not trial any of them.

Quote-only pricing is not a red flag by itself. Staffing suites handle assignment-level billing because that is their job, and even Bullhorn, which publishes Starter and Core prices, asks for a quote on Pro, Max and its Middle Office back-office product. But you cannot compare cost until you ask, so request three numbers in writing: the set-up fee, the monthly minimum and the rate per paid worker.

Read the AI column with one question in mind: does it touch the pay run? Bullhorn's Amplify and TempWorks' AI Hub are aimed at recruiting, and Avionté places its AI & Automation at job creation, candidate discovery, pre-screening and interviews. None of it is described as catching a wrong rate on Friday afternoon. If you are weighing the recruiting side separately, the Manatal, Loxo and Bullhorn Amplify comparison covers it.

What the pay-run AI features do and leave to you

Features that touch the pay run

QuickBooks describes its Payroll AI as collecting time and attendance from employees by text message or in its Workforce app, following a collection plan you set, then spotting inconsistencies and drafting a payroll for your review. The same page says it can run payroll when the admin tells it to by text. For a temp agency I would keep the collecting and the drafting, and put a second approver on the release.

Deputy AI is a conversational agent: you ask in plain English and it proposes an action for you to confirm. One example prompt on its page is a pay-run readiness check that asks whether any pending timesheets do not match the schedule. That only works when your temps' shifts are scheduled in Deputy in the first place. An agency whose temps simply clock in against client orders gives the check nothing to compare with.

Ubeya's AI sits on the scheduling and reporting side. Its AI Reporting covers costs, attendance and profitability, which helps with margin visibility, but its public pages do not describe a pay-run check.

Questions for any AI feature

• Does it act on its own, or only suggest and wait for a person to confirm?
• Who must approve before money moves, and is that enforced by user role?
• Which data can it read, and does any of it leave the vendor's platform?
• Is it in the plan price or an add-on? Deputy's pricing page marks its AI with a note that price and availability may change.
• Is every AI action logged with a user and a time, the way a manual change would be?

The longer version of this list, including how to tell machine learning from plain automation rules, is in which payroll features are real AI and what to ask.

A 45-temp agency choosing a route

Take a recruitment agency with an owner, two coordinators and a part-time finance person. About 45 temps are on weekly pay at any time across six client sites. Hours arrive as emailed photographs and text messages, and invoices go out on Fridays. Every figure from here on is an illustration built on the published list prices above.

What each route costs at 45 workers

Deputy counts every user, administrators and supervisors included, in the total, which is why the office staff are in the sum. QuickBooks advertises half-price base fees for the first three months, so the first quarter costs a little less than the table shows. Its pricing page currently lists Workforce only as a bundle with QuickBooks Online accounting and says a payroll-only plan exists without printing its price; if your books live elsewhere, ask for that figure in writing.

What the saved time is worth

The second table assumes the route you choose lets workers submit hours from a phone and gives clients an approval link. Worker hour capture is described on the Deputy and Ubeya pages, and QuickBooks says its Payroll AI collects hours by text or app. I could not confirm a client approval link on the public page of any of the six, which is why client approval is the demo test that decides.

That saves about 5.5 hours a week. Over 50 weeks at an internal cost of $24 an hour it is worth roughly $6,600 a year (5.5 × 50 × $24). Add the rate slips from the earlier example: two a month at $60 overpaid each is $1,440 a year. The total, about $8,000, beats Deputy Core ($3,744 a year) and the two Workforce Payroll bundles ($4,566 and $5,010), and roughly matches Premium + Plus ($7,836).

The comparison is not like for like. The QuickBooks bundles replace your payroll provider and your accounting software, while Deputy replaces neither, so subtract what you pay for both today before reading those totals. In this illustration the time saved alone ($6,600) does not pay for the Premium bundle; avoided overpayments and faster invoicing carry the case. The sum also cuts the other way: with 15 temps, re-keying costs under an hour a week (15 × 3.5 minutes), and a spreadsheet with a few checks may be enough.

Eight checks before any pay run is released

Whatever you buy, run the same checks before you release a run. Vendors automate some of them; the rest take twenty minutes with a spreadsheet export and a chat assistant. The thresholds are starting points, so set your own after a month of real runs.

1. Timesheets without client approval, counting a blank as not approved.
2. Workers whose combined hours across assignments pass 48 in a week, or move more than 40% from last week.
3. A pay rate on the timesheet line that differs from the assignment record.
4. Hourly margin (bill rate minus pay rate) below $3.00 or above $12.00.
5. Bank details created or changed in the last seven days.
6. The same worker with two sheets covering the same day.
7. Active assignments with no timesheet at all this week.
8. Workers paid for hours after their assignment end date.

A prompt for the checks an export can answer

Delete the name, address, bank and tax-number columns from the pre-run export and keep only worker codes. Use an assistant on a business plan whose data terms your firm has accepted, never a personal free account. If your policy keeps pay data out of chat tools altogether, ask the assistant to write the checks as spreadsheet formulas and run them locally, the approach in safe payroll prompts that never include pay data.

You are checking a weekly temp payroll export before release.
The data below is anonymised: worker codes only, no names or bank details.
Columns: row, worker_code, assignment_id, client_code, hours_normal,
hours_overtime, pay_rate, bill_rate, approved_by_client, last_week_hours.

Run these checks and give one short table per check, quoting the row
number for every flag:
1. Rows where approved_by_client is anything other than "Y" (blank counts as not approved).
2. Workers whose total hours across assignments exceed 48, or differ from last_week_hours by more than 40%.
3. Assignments where bill_rate minus pay_rate is below 3.00 or above 12.00.
4. Any worker with two rows on the same date, if a date column exists.

Rules: do not calculate pay, tax or deductions. Do not guess missing
values. If a column is missing, say which check you could not run.
Start by stating how many rows you read. Finish with three questions
I should answer before releasing the run.

Sample output and what to fix in it

An illustrative result for a 45-row export:

Three habits keep this honest. Make the assistant state how many rows it read and compare that with the export's own count, because a silently truncated paste is the commonest failure. Say "anything other than Y" in the prompt, since lower-case "y" and blanks otherwise slip through. And recompute any total in the spreadsheet instead of trusting the assistant's arithmetic: the 100.5 hours above is 38.0 + 40.0 + 22.5, and it takes ten seconds to confirm.

Chasing client approvals: before and after

Before: on Monday at 9:00 a coordinator emails nine clients. On Tuesday at 11:00 she phones the six who have not replied. On Wednesday morning the run is waiting on three supervisors, and two sheets are paid on a guess from the worker's photograph. After: a reminder goes out automatically on Tuesday at 10:00, a second at 15:00 to a backup approver named on the client record, and the coordinator phones only the clients still pending at 9:00 on Wednesday, three hours before a 12:00 cut-off.

Wording that gets answered is short, names the consequence and asks for one action. An illustrative first reminder:

Hi [first name], 7 timesheets for [client site] are waiting for your approval (link below). Hours approved by 12:00 on Wednesday are paid on Friday; anything later rolls into next week's run. It takes about a minute. Thanks, [your name]

An assistant can draft variations in three tones (friendly, firm, final) for a template library, but the schedule and the cut-off rule belong to you. Decide in advance what happens to hours nobody approves by the cut-off. Some agencies pay the worker's submitted hours and dispute them with the client later; others hold them to the next run. The right choice depends on your worker contracts, your client terms and the pay rules where you operate, so settle it with a payroll adviser before the first dispute rather than after.

The rate change that missed open timesheets

Here is a realistic slip. A client agrees a $0.75 an hour increase effective Monday. The coordinator edits the assignment on Wednesday, but the 14 timesheets already created that week keep the old rate. Those 14 workers at 38 hours each are billed 14 × 38 × $0.75 = $399 too little. Nobody notices for two weeks because the margin report shows a similar percentage for that client; the only clue is that the bill rate on the invoice lines no longer matches the assignment record.

The check that catches it is number 3 in the list above, run on invoice lines as well as pay lines. In a product that stamps the rate onto each timesheet when it is created, ask the vendor what happens to open timesheets when an assignment rate changes: updated automatically, flagged for review, or left alone. "Left alone" is acceptable if you know it and have a step for it, and expensive if you find out in week three.

Where AI should stay out of the pay run

• Releasing payment. A named person approves the run and a second person releases it. If a feature can run payroll by text message, restrict it by role or switch that part off.
• Bank-detail changes. A forged email asking to change where wages go is an easy way to divert pay. Changes need a call-back to a known number and dual control, whatever the assistant says about the email's tone.
• Statutory calculation. Deductions and filings come from the payroll provider's engine, not from a chat answer. Use the assistant to explain a line to a worker after the engine has produced it.
• Judging disputes. Whether a worker is owed hours that a client refused to approve is a contract and pay-rule question for you and your adviser.

What a small employer can safely hand over to AI in payroll sets out the same boundary for ordinary payroll, which is the safer starting point if you are new to this.

Contract points to settle before you sign

• How a worker is counted. Temps churn. Ask whether you pay for every person on the system, every person paid in the month or every person in a pay run, and whether archived workers still count.
• Minimums and promotions. Deputy applies a $30 monthly minimum on its monthly plans, and QuickBooks advertises half-price base fees for the first three months. Work out the cost of month four, not month one.
• Set-up and training. Ask whether implementation is charged separately, and get it as a line item.
• AI add-ons. Ask whether named AI features are included, whether you can switch them off and whether the price can change mid-term.
• Exit. Get the export format in writing: workers, rates, assignments and hours history as CSV.
• Two tools or one. Where payroll and invoicing sit in different products, read one platform or two tools before you decide.

Questions small agencies ask about temp payroll tools

Can ordinary payroll software run payroll for temps?

It can calculate the wages if it handles several pay rates per person and weekly runs. What it often lacks is the assignment, bill rate and client approval layer, so billing and sign-off move into spreadsheets. That is manageable for a handful of temps. Once re-keying hours takes a few hours each week, price a staffing suite or a time app with approvals.

Should clients approve timesheets in the software or by email?

Inside the software, if the product offers an approval link, because it records who approved which hours and when, and it can chase for you. Email approval only works if you save each message against the timesheet. Either way, set a cut-off and write into your client terms what happens to hours that nobody approves.

Is it safe to paste a pay-run export into a chat assistant?

Only after removing names, addresses, bank details and tax numbers, leaving worker codes, and only on a plan whose data terms your business has accepted. A safer pattern is asking the assistant to write each check as a spreadsheet formula, then running it on your own file so pay data never leaves your machine.

Why do staffing suites rarely publish prices?

Bullhorn's pricing page shows per-user prices for its Starter and Core editions only and asks for a quote on Pro, Max and add-ons such as Middle Office, which is typical of suites sold per business. Treat missing prices as a prompt to ask, not a reason to rule a vendor out. Request the set-up fee, monthly minimum, rate per paid worker, contract length and any AI add-on cost in writing.

How many people should approve a temp pay run?

Two: the person who prepared it and a different person who releases it. In a four-person agency that can be a coordinator and the owner. Give bank-detail changes the same dual control, because a forged request to change where wages go is an easy way to divert pay.
