Best Payroll Software for Accountants
For accountants and bookkeepers running payroll for clients, Gusto is the best overall platform: full-service filings, published pricing you can quote to a client without a sales call, and a client experience that doesn't generate support calls back to you. OnPay is the better pick when your client base is multi-state, since its flat $49/month plus $6 per person includes multi-state payroll.
The variables that matter in a practice are different from the ones that matter to a single business. You care about how fast a new client can be onboarded, whether you can see every client without logging in and out, whether prices are predictable enough to build into your fee, and whether filings are handled so payroll doesn't become an unbillable emergency in the last week of a quarter.
Ranking below reflects those practice-level concerns. Where a provider's accountant or partner program terms aren't documented on its review page on this site, we've flagged it to confirm rather than describing a program we haven't verified.

- 1Best overall for accountants
Gusto
Practices that want one predictable platform across most clients
Gusto is the easiest platform to standardize a book of clients on. Pricing is published — $49/month plus $6 per person on Simple, $80/month plus $12 per person on Plus — so you can build payroll into a client's monthly fee without waiting on a quote. Filings are full-service at federal, state, and local level, and employees onboard themselves, which removes the data-entry work that usually lands on the bookkeeper.
It also covers the requests that otherwise force a client onto a second vendor: health benefits in supported states, 401(k) integrations, contractor payments, and time tracking on Plus.
Where it falls short- Simple is single-state only, so multi-state clients cost more on Plus.
- Premium is quote-based, breaking pricing predictability at the top tier.
- Support is software-first, with no dedicated rep attached to your practice by default.
- being verified: confirm the current terms of Gusto's accountant/partner program before relying on partner pricing or a multi-client dashboard.

- 2Best for multi-state client bases
OnPay
Practices with clients paying employees across state lines
OnPay's single plan at $49/month plus $6 per person includes multi-state payroll, unlimited pay runs, federal, state, and local filings, and W-2 and 1099 filings. For a practice, one plan means one price to quote and no tier-mapping exercise per client.
It also removes a recurring conversation. When a client hires in a second state, nothing about their plan or bill structure has to change.
Where it falls short- Less polished than Gusto, which can mean more hand-holding for less technical clients.
- No cheaper contractor-only tier for clients who pay 1099s exclusively.
- Smaller integration ecosystem.
- being verified: confirm OnPay's current accountant partner program terms and multi-client access.

- 3Best for QuickBooks Online practices
QuickBooks Payroll
Firms whose clients are already standardized on QuickBooks Online
If your clients' books are already in QuickBooks Online, running payroll in the same ledger removes an entire reconciliation step every month, and it removes the sync failures that a third-party integration eventually produces. Core, Premium, and Elite are full-service.
We earn nothing from QuickBooks. It's ranked here purely because ledger-level integration is worth real time to a practice that's already standardized on QBO.
Where it falls short- Little advantage for clients not on QuickBooks Online.
- Feature parity with Gusto often requires a higher, more expensive tier.
- The $88/month plus $6.50 per employee price includes QuickBooks accounting, so it is not a like-for-like comparison against payroll-only providers (pricing verified August 2026).
- being verified: confirm current QuickBooks ProAdvisor payroll program terms.
- 4Best low-cost option for filing-only clients
Patriot Payroll
Clients where your firm already handles the tax filings
Patriot is the one platform on this page where the self-service plan is a legitimate professional choice. Basic Payroll runs the calculations and produces pay stubs while leaving the filings and deposits to whoever is responsible — and in a practice, that's often you.
If you'd rather not own the filings for a given client, Patriot's Full Service plan handles federal, state, and local filings with a tax filing accuracy guarantee, at one of the lowest base prices available.
Where it falls short- Basic Payroll transfers filing responsibility to you or the client — only choose it deliberately.
- Thin benefits and HR functionality if a client's needs grow.
- Basic Payroll is $17/month plus $4 per worker paid, but you handle the tax filings and deposits yourself; Full Service Payroll is $37/month plus $5 per worker paid (pricing verified August 2026).
- being verified: confirm Patriot's current accountant program and multi-client management features.

- 5Best for complex and larger clients
ADP RUN
Practices serving clients that outgrow small business payroll
ADP RUN scales from Essential Payroll through HR Pro, adding SUI management, HR help desk, and HR advisory, with a path further up ADP's product line as a client grows. For clients whose complexity exceeds what a published-price platform is designed for, this is the safe recommendation.
Every accountant already knows how to read ADP reports, which is not a trivial advantage when you're reconciling a new client's year-to-date figures.
Where it falls short- Quote-based pricing makes it hard to standardize a client fee.
- Dated interface, and add-on charges accumulate.
- Usually more expensive than the published-price options for small clients.

Prices shown come from each provider's review page on this site. Confirm current pricing with the provider before signing up — payroll pricing changes often.
Not a like-for-like price: QuickBooks Payroll is sold bundled with QuickBooks accounting, so its $88/month plus $6.50 per employee price is not a like-for-like payroll price against payroll-only providers like Gusto, OnPay, Patriot, or Square. Part of that figure buys accounting software.

How we picked
For accountants we weight practice-level workflow first: how quickly a client can be onboarded, how much data entry falls on your team versus the client's employees, and whether pricing is published clearly enough to build into a fixed monthly fee.
Then we weight filing coverage and multi-state handling, because those are the two places where a payroll problem turns into unbillable hours at quarter-end. We also value a platform's ability to cover benefits, contractors, and time tracking without adding a second vendor to a client's stack.
Partner-program specifics — revenue share, wholesale billing, multi-client dashboards — change frequently and aren't documented on the review pages we source from, so they're marked as items to confirm rather than described here.
Every provider is scored against the same criteria. Read our payroll software review methodology.
Frequently asked questions
What is the best payroll software for accountants?
For most practices, Gusto: full-service federal, state, and local filings, published pricing at $49/month plus $6 per person on Simple that you can build into a client fee, and employee self-onboarding that keeps data entry off your team. OnPay is the better fit if many of your clients pay employees in more than one state.
Should accountants use one payroll platform for every client?
Standardizing is usually worth it, because your team gets faster and support conversations get simpler. The common exception is clients already on QuickBooks Online, where running payroll in the same ledger saves a reconciliation step every month.
Can I keep filing payroll taxes myself for a client?
Yes, and Patriot's Basic Payroll plan is built for exactly that: it calculates payroll and produces pay stubs while leaving the filings and deposits to you or the client. Only choose it when your firm has explicitly accepted that responsibility in writing.
Which payroll platform handles multi-state clients best?
Among the published-price providers, OnPay, because multi-state payroll is included in its flat $49/month plus $6 per person. Gusto requires the Plus plan at $80/month plus $12 per person for multi-state, and ADP and Paychex handle multi-state routinely but price by quote.
Do payroll providers offer accountant partner programs?
Several do, typically involving partner pricing, wholesale billing, or a multi-client dashboard. Terms change often enough that we won't restate them here — confirm the current program details directly with the provider before you build them into your pricing.
The bottom line
Standardize on Gusto for most of your book, use OnPay where multi-state clients cluster, and keep QuickBooks Payroll available for clients already committed to QuickBooks Online.
Before you commit a practice-wide standard, get the provider's current partner program terms in writing. The platform decision is easy to reverse for one client and painful to reverse across fifty.
