ADP runs payroll for a very large share of the market and does the hard parts — multi-state tax, filings, compliance — properly. The complaints that lead people here are rarely about accuracy.

Why teams look
Interface and support friction. Long-running complaints about the admin experience and getting a person on the phone.
Contract and pricing opacity. Quoted per-payroll and per-employee pricing that is hard to compare and harder to exit mid-term.
Scope. ADP is payroll and adjacent HR. The questions companies struggle with — headcount against budget, capacity against pipeline, cost per project — need payroll data joined to delivery and finance data, which no payroll bureau does.
What you must not give up
Payroll accuracy and filings. This is the one place where "good enough" is not. Tax rules are jurisdictional, they change, and errors are visible to every employee and to the authorities.
If you move payroll, move it to another specialist, not to a general platform.
The realistic configuration
For most companies: keep a payroll specialist, and put the operations layer around it. Employee records, time off, performance, hiring and project economics belong in a connected system; filings belong with a provider whose job is filings.
That is what Brainis is for in this picture. People OS holds the employee record, time off, documents, onboarding, performance, learning and rewards, and shows pay runs and pay stubs — but it is not a payroll bureau and does not file your taxes.
Migration cautions
If you do change payroll providers:
Warning: Payroll is the single riskiest system to migrate and the one most often better left alone. Sequence it last, and be willing to conclude it should not move.
FAQ
Can HR data and payroll live in different systems?
Yes, and it is the common configuration. Decide which system is authoritative for the employee record and sync one direction.
What about multi-state or multi-country?
Specialist territory. Verify coverage for every jurisdiction you employ in rather than assuming.
