How do I ensure my catch-up bookkeeping with monthly bookkeeping services is GAAP-compliant?

To keep catch-up bookkeeping with a monthly bookkeeping service GAAP-compliant, the key is to make sure the cleanup process is handled like a proper accounting close—not just data entry. Here’s a practical checklist:

1) Reconstruct the books completely

Your bookkeeper should gather and organize:

• Bank and credit card statements
• Loan statements
• Payroll reports
• Sales reports
• Vendor invoices and receipts
• Prior tax returns
• POS/e-commerce reports
• Any missing prior-period documents

If records are incomplete, they should use reasonable, supportable estimates and clearly document them.

2) Reconcile every balance sheet account

GAAP requires accounts to be supportable and accurate. The catch-up process should include reconciliations for:

• Cash
• Accounts receivable
• Accounts payable
• Credit cards
• Loans and debt
• Payroll liabilities
• Sales tax payable
• Deferred revenue
• Fixed assets and accumulated depreciation
• Owner’s equity / retained earnings

If an account can’t be reconciled, it should be flagged and explained—not just forced to balance.

3) Record transactions in the proper period

GAAP uses the accrual basis for financial reporting unless you’re explicitly on a cash basis for a separate purpose. That means:

• Expenses go in the period incurred
• Revenue goes in the period earned
• Unpaid bills and uncollected revenue may need accruals
• Prepaid expenses and deferred revenue may need adjustment

Avoid dumping everything into the month it was discovered.

4) Make proper adjusting journal entries

Common GAAP adjustments in catch-up bookkeeping include:

• Accruing unpaid expenses
• Recording accounts receivable
• Recording accounts payable
• Deferring prepaid expenses
• Deferring unearned revenue
• Depreciating fixed assets
• Writing off uncollectible receivables
• Recording owner distributions or contributions properly

Each adjusting entry should have a clear explanation and backup.

5) Separate bookkeeping cleanup from tax reporting

GAAP and tax rules are not always the same. Make sure your monthly bookkeeping service is:

• Using GAAP for financial statements
• Not forcing tax-only rules into the books
• Coordinating with your CPA on permanent vs. temporary differences

This matters for items like meals, depreciation, charitable contributions, and certain fringe benefits.

6) Review and document assumptions

If the service has to estimate anything, they should document:

• What was estimated
• Why
• How the estimate was calculated
• What support was used
• Whether it will be trued up later

This is important for audit trail and consistency.

7) Use a month-end close process going forward

Once caught up, your monthly service should follow a repeatable close checklist:

• Reconcile bank/credit card accounts
• Review AR/AP aging
• Record accruals and deferrals
• Post depreciation
• Review loan balances
• Check payroll and sales tax liabilities
• Review equity accounts
• Produce financial statements
• Investigate unusual variances

8) Get CPA review if the books will be relied on externally

If the financials will be used for:

• A lender
• Investors
• Audit
• Tax filings
• Valuation
• Legal matters

have a CPA review the cleanup and the final month-end process. Bookkeepers maintain the records; CPAs often determine whether the financial statements are presented appropriately under GAAP.

9) Make sure the bookkeeping software is configured correctly

Your chart of accounts and settings should support GAAP reporting:

• Correct fiscal year
• Proper account types
• Accrual vs. cash basis setup
• Fixed asset tracking
• Sales tax settings
• Classes/locations if needed
• Consistent naming and coding

10) Ask for these deliverables

A GAAP-oriented catch-up service should provide:

• Reconciled balance sheet
• Profit and loss by month
• General ledger detail
• Journal entry log
• Open AR/AP aging reports
• Support for major adjustments
• Notes on unresolved items

Red flags to avoid

Be cautious if your bookkeeping provider:

• Ignores unreconciled balance sheet accounts
• Posts old transactions into the current month without explanation
• Uses “miscellaneous expense” heavily
• Can’t explain adjustments
• Doesn’t separate book and tax treatment
• Claims “GAAP-compliant” without reconciliation or documentation

Best practice

If the cleanup spans multiple prior months or years, treat it as a formal catch-up engagement with:

• A written scope
• Documentation standards
• CPA oversight where needed
• A finalized month-end close process going forward
