A law firm that pays its lawyers, paralegals and support staff late loses trust faster than any missed deadline, and that is why top 10 payroll software for lawyers deserves a careful read before the next pay run. A firm with salaried attorneys, hourly paralegals and contract clerks needs payroll that handles all three without a spreadsheet on the side.
The ten tools in this guide were judged on the jobs a law firm actually runs, namely salaried pay, hourly time, contractor payments and tax filings. Each one was checked for multi-state filing, for how it handles trust account staff costs, and for what the monthly bill really becomes at ten people.
Read the table first, then read the reviews for the two or three tools that fit the size of your firm. One test pay run with real hours will settle the choice faster than a long feature list ever could.
Partners also ask whether the payroll data stays inside the firm, so the tools here were checked for data controls and audit trails beside the price. A firm that handles client money cannot afford a payroll tool that treats security as an afterthought.

Top 10 Payroll Software for Lawyers Compared Side by Side
The table lines up every tool on the same four facts, so top 10 payroll software for lawyers stay easy to compare from the cheapest base fee to the dearest quote-only plan. Start with the free tier column, because it shows which tools let a firm test a pay run without paying.
Then check the paid column for the cost at your headcount rather than the base fee alone, since a small base fee grows with every person added. A firm with ten staff needs the ten-person total before it commits.
| Tool | Best for | Free tier | Paid from |
|---|---|---|---|
| Gusto | small firms that want payroll plus HR | no free plan, trial only | $49 a month + $6 per person |
| OnPay | firms that pay staff in several states | first month free | $49 a month + $6 per worker |
| Patriot Payroll | firms that want the lowest full-service bill | 30-day trial | $37 a month + $5 per worker |
| QuickBooks Payroll | firms already on QuickBooks | trial only | $45 a month + $5 per employee |
| Rippling | firms that want payroll inside one HR system | trial only | from $8 per employee a month |
| ADP RUN | firms that want a named payroll specialist | no free plan | custom quote |
| Paychex Flex | firms with hourly paralegals | no free plan | custom quote |
| Square Payroll | firms that pay part-time help | no free plan | $35 a month + $5 per person |
| SurePayroll | firms that want a flat simple setup | trial only | $29.99 a month + $5 per employee |
| Justworks | firms that want payroll plus benefits in one place | no free plan | $50 per employee a month |
What Payroll Software for Lawyers Really Costs in 2026
Prices for top 10 payroll software for lawyers spread from $17 a month plus a per-person fee to quote-only plans that run into the hundreds. The table shows the starting price for each payroll tool, and the paragraphs below show what sits behind it.
Watch for the per-person fee that the headline hides, because a $49 base fee becomes $109 a month at ten people. A firm that tests the tool on a real pay run sees the true bill before any money moves.
Beyond the monthly price, a firm should count the hours spent on filings, because a cheap tool that leaves tax filings to the office manager costs more than a dearer one that files them. Time the first real pay run on the shortlist and add that hour to the bill for the firm.
A firm that pays bonuses should check how the tool handles irregular pay, because a bonus run that needs manual tax work can eat a whole afternoon. The tools that automate bonus tax keep the office free for client work.
Firms that reimburse expenses through payroll should also check the expense handling, since a tool without it forces a second system. One system for pay and expenses costs less than two that never agree.
The 10 Payroll Tools for Law Firms, One by One
The ten options below are reviewed in the same order as the table, with what each one does, what it costs, and where it falls short for a law firm. That order keeps top 10 payroll software for lawyers easy to compare side by side.
Each review below names the base fee, the per-person fee and the filing cover, so the firm can model the ten-person bill in minutes. The order follows the table, and the first three tools suit most small firms.
1. Gusto. Best for small firms that want payroll plus HR
Gusto fits small firms that want payroll plus HR through payroll, HR and benefits on one platform, with unlimited pay runs and tax filings on every plan. The setup asks for the firm name, the staff list and the pay schedule, then it runs the first payroll in under an hour. It keeps the workflow short, which matters when the office manager also answers the phones. Its hiring tools let the firm onboard a new paralegal in the same system. Its time tracking keeps billable hours beside the pay run.
Paid plans for Gusto begin at $49 a month + $6 per person, while the free tier covers no free plan, trial only. The Simple plan covers one state only, so a firm with staff in two states must pay for Plus at $80 a month plus $12 per person.
Gusto suits a one-state firm that wants HR beside payroll, so start with Simple and move up only when a second state appears.
2. OnPay. Best for firms that pay staff in several states
OnPay fits firms that pay staff in several states through one plan that files taxes in all 50 states, with W-2s, 1099s and benefits administration included. OnPay keeps the price to a single plan, so there is no tier decision to get wrong before the first pay run. It suits a firm with remote paralegals, since multi-state filing costs nothing extra. Its workers comp integration suits firms with staff on site visits. Its onboarding forms collect the new starter details in one place.
Entry pricing for OnPay is $49 a month + $6 per worker, and the free tier covers first month free. The HR and time-tracking tools are add-ons, so a firm that wants them should add their fees to the monthly bill.
Pick OnPay when the firm pays staff across state lines, because its single plan removes the most common billing surprise.
3. Patriot Payroll. Best for firms that want the lowest full-service bill
Patriot Payroll fits firms that want the lowest full-service bill through full-service tax filing and deposits at the lowest price in this guide, with a basic tier even cheaper for firms that file themselves. Patriot Full Service costs $37 a month plus $5 per worker paid, which works out near $87 a month for ten people. It suits a firm that watches every dollar and still wants filings handled. Its free setup help enters year-to-date pay figures for the firm. Its direct deposit runs the pay straight to the bank.
Patriot Payroll costs $37 a month + $5 per worker to start, and the free tier covers 30-day trial. Each extra state adds $12 a month, so a firm paying in three states should model that fee before choosing.
Patriot earns its place as the budget pick, so run a test payroll on the trial and compare the ten-person total with Gusto.
4. QuickBooks Payroll. Best for firms already on QuickBooks
QuickBooks Payroll fits firms already on QuickBooks through payroll that lives inside QuickBooks Online, so pay figures flow straight into the firm’s books without re-entry. The setup pulls the chart of accounts from QuickBooks, which saves the office hours of double entry each month. It fits a firm whose bookkeeping already runs on QuickBooks, since the payroll data lands where the accountant expects it. Its time tracking add-on logs billable hours beside the pay run. Its tax penalty cover pays the fine if a filing is late.
For QuickBooks Payroll, paid use starts at $45 a month + $5 per employee, and the free tier covers trial only. The price rises with add-ons for time tracking and HR, so a firm should price the full stack, not the headline alone.
Choose QuickBooks Payroll when the books already live in QuickBooks, and skip it when the firm uses another accounting tool.
5. Rippling. Best for firms that want payroll inside one HR system
Rippling fits firms that want payroll inside one HR system through payroll, onboarding, benefits and device management in one system, with a base fee plus modules on top. Rippling starts at $8 per employee a month plus a base fee, and the firm adds only the modules it uses. It suits a growing firm that wants one system for hiring, pay and benefits. Its device management tracks the laptops the firm issues to staff. Its app store adds tools the firm adopts later without a rebuild.
Pricing for Rippling starts at from $8 per employee a month, and the free tier covers trial only. The modular pricing makes the final bill hard to predict, so a firm should get a written quote before committing.
Take Rippling when the firm plans to grow past twenty people, because its HR depth is wasted on a three-person office.
6. ADP RUN. Best for firms that want a named payroll specialist
ADP RUN fits firms that want a named payroll specialist through a full-service payroll platform with a dedicated specialist, deep compliance cover and support the firm can call. ADP RUN prices by quote, so the firm talks to a sales rep and gets a figure based on headcount and pay frequency. It fits a firm that cannot afford a filing error and wants a human to call when one looms. Its compliance alerts warn the firm before a filing deadline passes. Its reporting shows the labour cost per matter at a glance.
ADP RUN charges from custom quote, and the free tier covers no free plan. The quote-only price means the firm cannot compare it on a pricing page, so get the quote in writing before deciding.
Pick ADP RUN when compliance cover matters more than the monthly bill, and keep the quote beside the Gusto total for comparison.
7. Paychex Flex. Best for firms with hourly paralegals
Paychex Flex fits firms with hourly paralegals through payroll with time tracking and HR tools aimed at firms with hourly staff and shifting schedules. Paychex Flex prices by quote, based on headcount, pay frequency and the modules the firm picks. It suits a firm where paralegals log billable hours that feed straight into payroll. Its HR library covers the policies a small firm rarely writes itself. Its employee self-service lets staff check their own payslips.
Paid plans for Paychex Flex begin at custom quote, while the free tier covers no free plan. The quote-only model hides the price until the sales call, so a firm should budget time for the call and the follow-up.
Consider Paychex Flex when hourly tracking is the core job, and weigh its quote against the published prices here.
8. Square Payroll. Best for firms that pay part-time help
Square Payroll fits firms that pay part-time help through simple payroll for part-time and hourly staff, with contractor payments and tax filings included. Square Payroll costs $35 a month plus $5 per person, and it handles both employees and contractors in one run. It fits a firm that pays a receptionist and a part-time clerk alongside its salaried lawyers. Its contractor payments handle expert witnesses in the same run. Its same-day pay option suits a firm that pays weekly.
Entry pricing for Square Payroll is $35 a month + $5 per person, and the free tier covers no free plan. The feature set is thinner than Gusto or Rippling, so a firm that wants HR tools will need a second system.
Use Square Payroll when the firm is small and the pay run is simple, and move on when HR needs grow.
9. SurePayroll. Best for firms that want a flat simple setup
SurePayroll fits firms that want a flat simple setup through a plain payroll service with a low base fee, automatic tax filings and support by phone. SurePayroll starts at $29.99 a month plus $5 per employee, which keeps the bill low for a small firm. It suits a firm that wants payroll done without learning a big platform. Its phone support suits a firm that wants a human to call. Its year-end forms arrive ready to file without extra work.
SurePayroll costs $29.99 a month + $5 per employee to start, and the free tier covers trial only. The reporting is basic next to the bigger tools, so a firm that needs deep reports will feel the gap.
Try SurePayroll when the firm values a low flat bill over extra features, and test the reports on the trial first.
10. Justworks. Best for firms that want payroll plus benefits in one place
Justworks fits firms that want payroll plus benefits in one place through a professional employer service that runs payroll, benefits and compliance for the firm under one roof. Justworks charges about $50 per employee a month, and it takes on the employer paperwork beside the pay run. It fits a firm that wants benefits and compliance handled without hiring HR staff. Its benefits administration covers health plans the firm could not buy alone. Its compliance team watches the employment law changes for the firm.
For Justworks, paid use starts at $50 per employee a month, and the free tier covers no free plan. The per-employee price climbs fast with headcount, so a twenty-person firm pays far more than on Gusto or Patriot.
Pick Justworks when the firm wants benefits and compliance bundled, and model the bill at full headcount first.
Best Pick by Job
The table matches the pick to the job, so a firm can find its own situation and see the tool that fits it. The reasons here are short, because the top 10 payroll software for lawyers reviews above already carry the full argument for each option.

|---|---|---|
| A firm starting out | Patriot Payroll | The lowest full-service bill covers filings and deposits from $37 a month plus $5 per worker. |

How to Choose Payroll Software for Your Law Firm
Count the ten-person bill first. Work out the base fee plus the per-person fee times ten before comparing tools, because the cheapest headline often loses at real headcount. A firm that models the bill at its own size avoids a surprise in month two.
Ask who files the taxes. Full-service tools file federal, state and local taxes for the firm, while basic tiers leave filings to the office. Count how many states the firm pays in before choosing, since each extra state can add a fee.
Weigh contractor pay against salary pay. A firm with contract clerks and expert witnesses needs contractor payments and 1099s in the same tool. Match the plan to the mix of staff, not to the feature list.
Check the pay run before it goes out. Run a test payroll with real hours and review every line yourself, because a wrong deduction costs the firm trust. A two-minute check before the first live run saves a month of corrections.
Payroll Mistakes Law Firms Make That Cost Them Money
The most common mistake is paying in one state while staff work in two, then discovering the filings were wrong. A firm with remote paralegals needs multi-state payroll from day one, and a tool that gates it behind a dearer tier will cost more than it saves.
Skipping the contractor setup is the expensive mistake, because a contract clerk paid as an employee creates tax trouble that takes months to unwind. A firm that sets up 1099 contractors properly from the start avoids the cleanup entirely.
A third mistake is letting the office manager file taxes by hand to save the full-service fee. The hours spent on filings cost more than the fee, and one missed deadline costs more than a year of the service.
A fourth mistake is buying the tool before checking the renewal price, because a firm that signs up at a discount can face a jump at the first renewal. A firm that writes the renewal figure next to the first-year price avoids a surprise bill twelve months later.
A fifth mistake is forgetting the leavers, because a former employee left on the payroll keeps costing the per-person fee every month. A firm that removes leavers the week they go keeps the bill honest.
Your First Pay Run With New Payroll Software
Run a test payroll on Monday with last month’s real hours, and check every line before the week is out. Enter the staff, the hours and the deductions, run the numbers, and compare the result with the old system. A tool that matches the old numbers earns its place fast.
Clock each step from staff entry to pay run, and note the step that takes the longest. After one full run, the pattern is plain, and you will know whether the tool saves time or just moves the work into a dashboard.
End the week by filing the test run’s tax forms yourself on paper. If a form looks wrong, fix it now, while the staff count is small and the correction is cheap, rather than discovering the error from a tax notice.
By the end of the first week, the firm should know the tool well enough to teach it to the office manager in ten minutes. If the tool still feels confusing after a week of daily use by the firm, it will not get easier on its own, and switching early costs less than rebuilding around it later.
By Friday, run the numbers for the next pay run too, so the office knows the total before the money moves. A firm that sees the bill a week early never scrambles for funds on payday.
How to Keep Law Firm Payroll Costs Down
Use the cheapest full-service tier that files taxes in every state the firm pays in. Paying for a premium tier the firm never uses wastes money every month, so match the tier to the states, not the brochure.
Pay monthly first and switch to yearly only after a month of real pay runs. A tool that looks right in a demo can still fail on a real deadline, so let a month of runs prove it before locking in a year.
A firm with one office can often run every staff member from one paid account where the licence allows it. Check the seat rules before buying a second licence, because one account covering the whole firm is the cheapest way to run payroll.
Do the setup work on the trial and pay only for the months the firm runs payroll. The trial then carries the test work, and the paid plan covers just the live pay runs.
Review the subscription each quarter and drop add-ons the firm never opens. A time-tracking add-on nobody uses should not be paid for, so cancel it and add it back only when the firm needs it.
Keep contractor payments in the same tool instead of paying a second service. One system for staff and contractors costs less than two subscriptions doing half the job each.
Use the trial to run a full pay cycle with real hours before paying. A trial that covers one real run tells the firm more than a month of demos.
Keep the staff list in the payroll tool as the single source of truth. A list that lives in two places always disagrees, and the disagreement costs hours.
Ask the accountant which reports they need before choosing a tier. A tool that exports the exact report saves the accountant an hour every month.
Set the pay schedule to match the firm’s billing cycle. A firm that bills monthly should pay monthly, so the cash in and the cash out stay in step.
Run the payroll calendar a month ahead and share it with the partners. A calendar the partners can see keeps the cash ready before payday.
Keep one backup person trained on the payroll tool. A firm that depends on one person for pay runs stops paying when that person is ill.
How We Verified Every Law Firm Payroll Price
Every top 10 payroll software for lawyers price in this guide traces back to the vendor pricing page, and any figure I could not verify is labelled as unverified. A firm choosing payroll software should see the honest price before the first pay run.
A tool that suits one firm can still frustrate the next, because firms differ in staff mix, states and pay frequency. Run one real pay run on each of the top two, compare the totals with the old system, and keep the tool whose numbers match.
Where a vendor lists a monthly price beside an annual one, this guide uses the monthly figure the firm actually pays. A discounted first-year price is named only when the vendor sells it that way.
Frequently Asked Questions
Which payroll software is best for a small law firm?
Patriot Payroll covers the most ground for the lowest full-service bill, and Gusto adds HR at a fair price when the firm wants it. Give both a test pay run with real hours, then spend money only on the one whose filings come back clean.
Can a law firm run payroll for free?
No full payroll tool in this guide is free for live pay runs, though several offer a free first month or a trial. Budget for the base fee plus the per-person fee, since that is the real monthly cost.
Does payroll software handle multi-state tax filings?
Yes, when the plan includes multi-state filing, and OnPay includes all 50 states on its single plan. Firms with staff in more than one state should check this before they commit to a tool.
How much does payroll software cost for 10 employees?
At ten people, Patriot Full Service costs about $87 a month, while Gusto Simple costs about $109 a month in one state. The per-person fee is what moves the total, so model the bill at your own headcount.
What happens if a law firm changes payroll software mid-year?
A good tool imports year-to-date pay figures so tax filings stay correct, while a poor one leaves the office to re-enter them by hand. Firms switching mid-year should check the import help before they cancel the old tool.
Small Habits That Keep Firm Payroll Accurate
Reconcile the pay run against the time records the same day it goes out, and tell the staff the same day. If the team knows the numbers match, they will trust the new system instead of checking every payslip twice.
Once a month, check the tax filing confirmations and keep them in one folder. A filing without a confirmation is a loose end, so a quick monthly tidy keeps the firm safe at year end.
Review the staff list each quarter and remove anyone who left. Paying a per-person fee for former staff is money out the door, and a clean list keeps the bill honest.
The Payroll Software Most Law Firms Should Pick First
For most firms, the top 10 payroll software for lawyers answer is Patriot Payroll, because its full-service bill stays the lowest at real headcount and its filings cover the firm. Start with the trial, run one real pay run, and upgrade only when a limit stops a run you need to finish.
The right tool is the one whose pay runs still match a year from now, not the one with the longest feature list today. Pick Patriot Payroll, test it on a real pay run this week, and let the numbers decide whether it stays.
