Q3 Accounting Checklist: Key Actions to Prepare for a Smooth Year-End Close

As the third quarter unfolds, accounting teams should shift into preparation mode for year-end. Q3 offers a strategic window to review financial performance, clean up data, and fix lingering issues—before the rush of the fourth quarter.

By taking time now to perform a thorough accounting review, firms can improve forecasting accuracy, avoid costly surprises, and set the stage for a stress-free year-end close. Below is a checklist of Q3 accounting functions every firm should prioritize.

1. Reconcile Balance Sheet Accounts

Before year-end, your books need to be airtight. Use Q3 to verify and reconcile all major balance sheet accounts:

• Bank accounts: Ensure monthly reconciliations are current and properly documented.
• Accounts receivable and payable: Tie subledger reports to the general ledger.
  • Do this by running the General Ledger (GL) Reconciliation report, located in Utilities in Deltek Vantagepoint.
• Unbilled revenue and work in progress (WIP): Confirm that earned revenue is recognized accurately.
• Prepaids and accruals: Review for proper allocation and timing.

Don’t wait for year-end to uncover discrepancies—identify and resolve them now while there’s still time to investigate.

2. Review Project Data and Statuses

Project-level accounting has a direct impact on financial reporting and profitability. Q3 is the time to:

• Validate project statuses and close out completed projects. This includes marking them as active, dormant, or inactive in Deltek Vantagepoint.
• Review on-going projects with project staff to ensure budgets and timing is accurate.
• Ensure all job-to-date labor and expense is recorded.

A well-maintained project database reduces billing delays, improves reporting accuracy, and supports better decision-making heading into Q4.

3. Clean Up Vendor and Client Records

Outdated or duplicate vendor/client data can create payment delays, compliance issues, and audit red flags. During Q3 is a great time to:

• Merge duplicate vendors and clients in your accounting system.
• Ensure there is a W-9 on file for all vendors and verify the proper tax classification is selected.
• Review payment terms and outstanding balances

Getting your vendor and client data in order now will simplify 1099 prep and reduce friction during the January crunch.

4. Audit Timesheets and Labor Cost Allocations

Labor is often a professional services firm’s largest cost, and any misallocations or gaps can lead to revenue leakage or compliance risk. Tasks to begin in Q3 include the following.

• Confirm all timesheets are submitted and approved.
• Audit for correct project/task assignments.
• Check for missing or duplicate time entries.
• Ensure labor costs align with billable and overhead expectations.

Regular audits also help with resource planning and team utilization analysis as you forecast Q4 and beyond.

5. Analyze Budget vs. Actuals and Forecast Year-End Performance

Q3 provides a crucial opportunity to assess how your actual performance aligns with your budget—and to adjust expectations accordingly. Recommended tasks are:

• Run YTD financial reports and compare to the annual budget.
• Identify underperforming or overperforming areas. /li>
• Update year-end forecasts based on real data.
• Communicate adjustments to leadership and project managers.

This not only helps course-correct for Q4 but also strengthens next year’s budgeting process.

6. Examine Unbilled Services and Revenue Recognition

Leaving revenue on the table is a common risk, especially for project-based firms. To avoid before year-end do the following:

• Review all open projects for unbilled time and expenses.
• Check for projects where work is complete, but billing hasn’t occurred.
• Ensure revenue recognition aligns with accounting policies and GAAP.

Addressing billing gaps now improves cash flow and ensures revenue is appropriately captured in the current year.

7. Evaluate Internal Controls and Approval Workflows

As your firm evolves, your internal controls should too. This includes:

• Reviewing user roles and system permissions.
• Testing approval workflows for purchases, timesheets, and billing.
• Confirming separation of duties and audit trails are in place.
• Tightening controls around sensitive financial areas.

Proactive control reviews can prevent fraud, errors, and compliance issues before they become audit findings.

8. Begin Preliminary Year-End Planning

While it may feel early, beginning year-end planning in Q3 can prevent bottlenecks later. Consider:

• Scheduling year-end close tasks and assigning responsibilities.
• Communicating deadlines for final billing, AP entries, and expense reports.
• Reviewing your audit prep checklist.
• Updating documentation for policies and procedures.

Firms that start planning in Q3 consistently report smoother closes and fewer surprises in January.

Q3 is Your Prep Season

Think of Q3 as your accounting “halftime.” It’s the perfect time to assess performance, fix gaps, and get your financial house in order—so when Q4 hits, you’re ready to sprint to the finish.

A disciplined mid-year review sets the foundation for a clean close, reliable reporting, and confident decision-making. The work you do now pays dividends in accuracy, efficiency, and peace of mind later.
