How a Payroll Partnership Works for CPA Firms (and What to Vet)
A payroll partnership lets a CPA firm offer payroll while a payroll team, working under the firm’s name, runs the processing, filings and support.
A team of payroll and HR professionals.
Payroll looks like a simple add-on for a CPA firm, until you try to run it in-house. Between deadlines, corrections, compliance details and the “someone quit yesterday” emergencies, payroll can drain a CPA firm’s capacity fast.
Why clients ask CPA firms for payroll
Clients already trust their CPA with the numbers, so payroll feels like a natural next request. It is ongoing, tied to long-term client relationships and hard to step away from once it is running.
That is why many firms work with a payroll partner instead of building an internal payroll department.
How the partnership works
The payroll partner does the payroll work, and your firm keeps the client relationship.
Your firm offers payroll as part of its client service. The partner runs processing, tax filings, corrections and day-to-day support, so your staff stay on accounting and advisory work.
A simple payroll handoff workflow
Use one repeatable workflow for every client, not a custom process for each.
Intake
Confirm employee counts, pay frequency and complexity, and set expectations early.
Handoff
The payroll partner takes over setup, system access and processing.
Ongoing support
The partner handles processing and issues. Your firm keeps the advisory relationship.

Partner vetting checklist
Use this checklist before you bring a payroll partner to your clients.
Systems: A strong payroll partner works inside existing payroll systems rather than forcing migrations.
Emergency coverage: Someone should step in when internal payroll contacts resign or systems fail.
Compliance: Experience across federal, state and local jurisdictions, especially for multi-state clients.
Responsiveness: Clear escalation paths and defined response times.
How to position payroll inside CAS
Payroll fits inside Client Accounting Services (CAS) as a managed service delivered through a payroll partner, with defined responsibilities, so your firm stays focused on advisory work.
How a partnership with PayAdvisors works
We provide managed payroll and emergency payroll support inside the systems your clients already use. Each pay run, the client’s approver signs off before anything is submitted, and your firm receives the payroll reports it needs for the books, such as general ledger files.
“Nothing but praise for the team at Pay Advisors.”
“Couldn’t recommend them enough for a company growing into its shoes and not quite needing in house staff, but trying to minimize the number of outside companies that it needs from a back office perspective.”

Frequently asked questions
What is a payroll partnership for a CPA firm?
A payroll partnership is an arrangement where the CPA firm keeps the client relationship and a payroll partner runs processing, filings, corrections and support.
How do responsibilities split in a payroll partnership?
Your firm keeps the client relationship and expectation setting. The payroll partner owns processing, tax filings, corrections and day-to-day support.
Do our clients have to switch payroll systems?
No. We work inside the systems your clients already use, whatever major payroll system that is.
Who handles a client’s payroll emergency?
The payroll partner does. Emergency payroll coverage is part of the partner’s scope, and our team can step in with the client’s next pay run after confirming the pay date, system access and records.
