Outsourced bookkeeping for a CPA firm means handing routine reconciliation and transaction categorization work to an outside provider, while the firm keeps client relationships, final review, and advisory work in-house. It’s the standard fix for the same wall small firms run into every busy season: more write-up bookkeeping work than staff hours to do it in.
What actually gets handed off?
The scope is narrower than firm owners sometimes expect. A typical outsourced bookkeeping arrangement covers:
- Monthly bank and credit card reconciliation
- Transaction categorization inside the firm’s existing chart of accounts
- Cleanup of miscategorized or unreconciled prior-period entries
- Delivery of review-ready books in the software the firm already uses
What stays with the firm: client relationships, final review and sign-off, tax strategy, and anything that requires the firm’s own judgment about a client’s specific situation.
How does access work without handing over the keys to the business?
This is usually the first question a firm owner asks, and it’s a fair one. The answer is a client-controlled access model: the firm grants accountant-level or staff-level access inside its own accounting software rather than sharing full account credentials. That matches the IRS’s own guidance for tax professionals in Publication 4557, Safeguarding Taxpayer Data. Access is scoped to what’s needed for the engagement and can be revoked at any time. See how RazaPro handles this in detail.
Does outsourcing bookkeeping actually save money?
It changes the cost from fixed to variable. The median annual wage for US bookkeeping, accounting and auditing clerks was $50,670 in May 2025, according to the U.S. Bureau of Labor Statistics. Employer Social Security, Medicare and federal unemployment tax bring one hire to about $54,588 a year, before state unemployment tax, benefits and software. For the same client work, RazaPro’s standard package costs about 30% to 45% of what that hire costs per client. Your numbers will differ with your client mix and the review time your own team spends, so the white-label margin calculator lets you model it with your own figures. The comparison isn’t just headcount cost — it’s also the ramp-up time of hiring and training a seasonal employee versus starting a trial engagement with a provider that already does this work daily.
What does onboarding actually look like?
Most engagements start with a trial period on a defined, limited scope — a handful of clients or a single month of catch-up work — rather than an immediate full handoff. This lets a firm evaluate turnaround time and quality directly before deciding whether to expand the arrangement across more of its write-up client base. RazaPro’s pilot is free for 30 days on up to 3 standard clients, and wholesale prices are published.
Is this only useful during tax season?
No, though tax season is when the pain is most visible. Firms that keep an outsourced bookkeeping relationship running year-round avoid the spike-and-crash cycle of hiring temporary staff every January and losing that capacity every May. A steady arrangement also means client books stay current throughout the year instead of arriving at tax season already behind.
What rules apply when the partner is offshore?
Client notice under AICPA ET 1.150.040, a confidentiality agreement or client consent under ET 1.700.040, Section 7216 consent if tax return information goes to a preparer outside the US, and service-provider oversight under the FTC Safeguards Rule. The details, with a controls checklist and the real cost of an in-house hire, are in offshore bookkeeping for US CPA firms.
