Before hiring an outsourced accounting or bookkeeping service, define the work you need, compare written scopes and fees, check qualifications for any tax-preparation work, and confirm that you will retain access to complete business records. In the U.S., outsourcing the work does not transfer your responsibility to keep records that support your tax reporting.
Define the work before you compare providers
“Accounting” and “bookkeeping” can cover different tasks, so describe what your business needs rather than relying on a provider’s general service label. List the work you expect, such as transaction recording, account reconciliations, payroll support, monthly reporting, catch-up or cleanup work, and tax preparation.
Ask each provider to identify what is included and excluded, what information you must supply, what decisions remain yours, and what the provider will deliver and when. AICPA engagement-letter guidance says a clear scope helps identify and avoid scope creep. AICPA engagement-letter guidance
- Which accounts, transactions, entities, or locations are covered?
- How often will reconciliations and reports be completed?
- Are payroll, tax preparation, cleanup, or advisory work included, or billed separately?
- What records must you provide, and by what deadline?
- How will the provider handle missing documents, unusual transactions, or questions requiring your approval?
Check qualifications for the specific work
Credentials matter differently depending on the service. IRS guidance on choosing a tax return preparer recommends checking the provider’s credentials or Annual Filing Season Program completion in the IRS directory, disciplinary history, fees, e-file authorization, and year-round availability. It also advises reviewing the return before signing. You remain responsible for the information on your tax return. These are tax-preparer checks; they do not establish a universal credential requirement for bookkeeping providers. IRS guidance on choosing a tax professional
If a provider will both maintain your books and prepare tax returns, ask who performs each task and what qualifications apply to the person responsible for the tax work. Confirm whether tax preparation is actually part of the engagement rather than assuming it is included because the firm offers it.
Compare written scopes, responsibilities, and fees
Request a written engagement letter or service agreement before work begins. It should identify the services, deliverables, schedule, fees and billing method, client responsibilities, confidentiality terms, and how either party can end the relationship. AICPA guidance recommends signed, regularly updated engagement letters for most engagements and says evergreen engagement letters are not recommended. AICPA engagement-letter guidance

Compare proposals on the same assumptions, not just the headline fee. Ask providers to specify the transaction volume, accounts, reporting frequency, turnaround time, point of contact, escalation process, and charges for out-of-scope work. The available guidance does not establish a reliable current market price range, so a quoted fee is meaningful only alongside the workload and services it covers.
| Compare | What to establish in writing |
|---|---|
| Scope | Included services, exclusions, covered accounts or entities, and assumptions about transaction volume |
| Responsibilities | What you provide or approve, and what the provider prepares or completes |
| Deliverables and timing | Reports, reconciliations, tax work if applicable, delivery dates, and turnaround expectations |
| Fees | Billing method, recurring charges, one-time cleanup fees, and rates or terms for additional work |
| Communication | Primary contact, response expectations, and how urgent or unresolved issues are escalated |
| Exit terms | Notice, termination rights, and how records and accounting data will be returned |
Keep control of your records and system access
The IRS says businesses may choose any recordkeeping system suited to their operations, provided it clearly shows income and expenses. Records should support income, expenses, deductions, and credits; be organized and safe; and remain available for tax administration. IRS Publication 583

For electronic systems, the IRS requires records to preserve, retrieve, and reproduce legible, complete, and accurate information. IRS guidance on electronic recordkeeping systems Ask who owns the accounting-system account, who has administrator access, how you can retrieve records and reports, and what format the provider will use to hand over the books if the relationship ends. Retain your own access rather than depending on the provider as the only route to your business records.
Ask how the provider manages data and third-party risk
Outsourcing may bring efficiency or cost benefits, but it also creates risks that your business should identify, assess, and manage. Ask which people or subcontractors can access financial information, what controls govern access and data handling, and how access is removed when someone no longer needs it.

A report is useful only if it relates to the work and risks you are evaluating. AICPA overview of SOC services
