How AI Saved 25 Hours of CPA Work
AI is already changing the way accountants, CPAs, and business owners work with financial information.
In this episode of the Financially Fit Business podcast, I talk with Peyton Witt, CPA, about a real example of how he used Claude AI to clean up vendor invoices for one of his clients.
The client knew their financial data was not accurate. Their accounts payable balance was overstated, their expenses were overstated, and vendor payments were not reducing the AP balance the way they should have.
That’s a problem because inaccurate accounts payable data can make your financial statements misleading. If you can’t trust the numbers, it’s much harder to make good business decisions.
Using AI as an Internal Control
Peyton explained that one of his internal controls is checking vendor balances and invoice amounts for the larger vendors.
For this client, he exported data from QuickBooks, removed client-identifying information, and used Claude to help flag possible duplicate invoices.
He prompted Claude to look for duplicate invoice numbers, matching dates, matching amounts, and other patterns that could point to duplicate entries. Claude helped identify which items needed a closer look.
The AI didn’t replace professional judgment. Peyton still verified the results and manually cleaned up the records in QuickBooks. But Claude helped him find the issues much faster.
Why This Matters for Business Owners
For many businesses, especially contractors and service companies, accounts payable can get messy fast.
Vendors may offer Net 30 terms. Field employees may buy supplies, materials, and parts. Invoices can be entered more than once. OCR tools can miss information or duplicate records.
When that happens, your financial statements may show expenses and liabilities that aren’t accurate.
Peyton estimated that manually reviewing the duplicated transactions could have taken 25 hours or more. Using Claude helped him identify the issues in about an hour, plus the time needed to verify everything and make the corrections.
That saved time for his staff and money for his client.
AI Can Help, But It Still Needs Oversight
One of the most important points Peyton made is that you shouldn’t blindly trust AI.
AI can be a powerful tool for reviewing large amounts of data, spotting patterns, and identifying possible problems. But it still needs human review, accurate prompting, and good data controls.
Peyton also emphasized the importance of protecting client information. Before using AI tools with financial data, remove sensitive information and understand the privacy and compliance issues involved.
The Bigger Lesson
Clean financial data matters.
If your accounts payable, accounts receivable, or vendor balances are wrong, your financial statements may not reflect what’s really happening in your business. That can lead to poor decisions, cash flow surprises, and unnecessary stress.
AI can help make the cleanup process faster. But the real value comes from using it with good controls, financial knowledge, and careful review.

Common Questions About AI and Accounting Accuracy
How can AI help CPAs clean up vendor invoices?
AI can help review invoice data, flag possible duplicates, compare invoice numbers, and identify matching dates or amounts that may need a closer look.
Can AI replace manual accounting review?
No. AI can help speed up the review process, but an accounting professional still needs to verify the results and make the final corrections.
Why are duplicate vendor invoices a problem?
Duplicate vendor invoices can overstate accounts payable and expenses. That means your financial statements may not show what’s really happening in the business.
Is Claude useful for accounting work?
Claude can be useful for reviewing data, finding patterns, and flagging possible errors. But it needs good prompting, careful review, and proper privacy controls.
What should business owners learn from this episode?
Business owners should make sure their accounts payable and accounts receivable numbers are accurate. Clean financial data helps you make better decisions.
