⭐ The 90‑Day Audit Prep Timeline
(What To Do and When)
By Pennies Count
Audit season rarely feels overwhelming because of the audit itself — it’s the timing.
Most nonprofits wait until the auditor requests documents, and by then, it’s already too late to fix the issues that matter. A smooth audit doesn’t start with the auditor. It starts with your internal timeline.
Here’s a clear, practical 90‑day audit prep roadmap to help you stay ahead of the process and avoid unnecessary stress.
📌 90 Days Before the Audit
Close the Books Cleanly
This is your foundation. Your goal is to ensure the year is fully and accurately closed.
Focus on:
• Completing all reconciliations (bank, credit card, payroll, loans)
• Reviewing the trial balance for unusual or negative balances
• Posting all year‑end adjustments
• Ensuring all accounts tie out to supporting documentation
• Cleaning up suspense or “ask my accountant” accounts
A clean close eliminates 80% of audit issues before they ever appear.
📌 60 Days Before the Audit
Organize Your Documentation
Auditors love structure — and this is when you gather the documents they’ll request first.
Prepare:
• Bank reconciliations
• General ledger
• Trial balance
• Grant schedules
• AP and AR aging reports
• Fixed asset schedules
• Payroll summaries
• Board minutes
Create a single Audit Folder with subfolders for each category.
This alone can cut days off your audit timeline.
📌 30 Days Before the Audit
Review Prior Findings and Adjustments
This is where most nonprofits fall behind.
Look at:
• Last year’s audit report
• Management letter
• Proposed and posted adjusting journal entries
• Any repeat findings
• Any internal control recommendations
Your goal is to confirm whether issues were resolved — or if they’re still present.
If the same adjustments or findings appear year after year, auditors will expand testing.
📌 2 Weeks Before the Audit
Do a Final Pre‑Audit Check
This is your last chance to catch issues before the auditor does.
Review:
• Reconciliations (are they current?)
• Documentation (is anything missing?)
• Grant schedules (do they tie to the GL?)
• Manual journal entries (are they properly supported?)
• Large or unusual transactions
If something looks off, fix it now — not during fieldwork.
⭐ Why This Timeline Works
This 90‑day structure gives you:
• Clarity
• Control
• Predictability
• Fewer surprises
• A smoother audit
• Lower audit fees
• Less stress for your team
Most importantly, it helps you avoid the last‑minute scramble that makes audit season feel chaotic.
