Big Accountants provides outsourced accounting for CPA firms and accounting practices across the US. We work as an extension of your team: preparing monthly bookkeeping, reconciliations, cleanups and tax workpapers to your standards, so your staff can focus on review, advisory and client relationships.

Most firms are not short of clients. They are short of trained people to do the preparation work, especially between January and April. We give you a reliable, trained team you can scale up and down, working in your software, following your checklists and staying invisible to your clients if you prefer.

  • Monthly bookkeeping and reconciliations
  • Catch up and cleanup projects
  • Payroll journal and accrual entries
  • Trial balances and tax workpapers
  • Accounts payable and receivable support

FAQ

Outsourced Accounting for Firms FAQs

What is outsourced accounting for CPA firms?

Outsourced accounting for CPA firms means an external team prepares bookkeeping, reconciliations, cleanups and tax workpapers for the firm’s clients, following the firm’s procedures, while the firm keeps the client relationship and reviews the work.

Is your service white label?

Yes. We work under your firm’s name, inside your software and systems, and do not contact your clients unless you ask us to.

How do you handle client confidentiality?

We sign a confidentiality agreement before work starts, work only in systems you control, limit access to assigned staff and protect data under a written information security plan.

What about tax return information and consent rules?

Where tax return information is disclosed to preparers outside the United States, Treasury Regulation 301.7216-3 sets consent and safeguard requirements. We work with you to keep the required consents and safeguards in place.

Which software do you work in?

We work in QuickBooks Online, QuickBooks Desktop, Xero and Zoho Books, and follow your firm’s workflow and document management tools.

Can you scale up for tax season?

Yes. Firms often add hours for January to April and reduce them after. We agree capacity in advance so the team is trained before the peak.

How do you make sure work meets our standards?

We learn your checklists and review notes during onboarding, start with a pilot group of clients and track your review feedback so issues are fixed at the source.

How much does outsourced accounting for firms cost?

Cost depends on client files, transaction volume, the work involved and turnaround. We offer a competitive fixed monthly fee, hourly billing or per task pricing, quoted in writing after a free call.
