# Expense Report Audit: done-for-you AI automation by BufferSol

> A done-for-you expense audit automation is an AI agent that reviews every expense report, not a sample. It reads each receipt, compares it with the card transaction and the claimed amount, applies your travel and expense policy, and looks for duplicates, split charges, weekend spend and blocked merchants. Clean reports move to approval with a one-line summary. Questionable lines go to a finance reviewer with the reason. BufferSol builds it into your expense tool and ERP.

## Every expense report checked against receipts and policy before it is paid

**Who it is for:** Finance teams at companies where dozens or thousands of employees travel or spend on company cards through SAP Concur, Expensify, Ramp, Brex, Navan or Emburse, and auditing today means a spot check.

### Signs you need it
- Finance audits a sample of reports because there is no time to look at them all.
- Managers approve reports on their phone without opening a single receipt.
- The same dinner appears on two people's reports and nobody notices until much later.
- Employees wait a long time for reimbursement and complain to HR.
- The written policy says one thing, and what gets approved says another.

## Business outcomes
- **Every report reviewed.** All lines are checked against receipts, card data and policy, so spend in the reports nobody sampled no longer goes unseen.
- **Faster payback for clean reports.** Reports with no issues reach the manager with a summary and move to payment sooner, which employees notice.
- **Policy applied the same way for everyone.** The same rules run on every report, and findings by team, merchant and rule show leaders where the policy needs changing.

## How it works today
1. Employees photograph receipts, type amounts and pick categories in the expense tool.
2. Managers approve from email or the mobile app, usually without opening attachments.
3. An AP or travel and expense auditor pulls a weekly sample and checks receipts against amounts and policy.
4. They send reports back with questions by email and wait for corrected receipts.
5. Finance exports approved reports to the ERP and fixes GL and department coding by hand.

Hidden costs:
- Out-of-policy and duplicate spend in unsampled reports is paid without anyone seeing it.
- Employees float company costs on personal cards while they wait for repayment, which hurts morale.
- Audit findings arrive months later, when the money is gone and nobody remembers the trip.

## How it works done for you
1. When a report is submitted, the agent reads every receipt image and pulls the matching card or bank transaction.
2. It checks amount, date, merchant, currency and tax against each claimed line, and reads itemized receipts to apply per-person limits for meals and lodging.
3. It applies your policy: per diems by city, pre-approval for flights, alcohol rules, mileage against a route estimate, and blocked merchant categories.
4. It looks across reports and people for duplicate receipts, charges split to stay under approval limits, and the same cost claimed on a card and as out-of-pocket.
5. Clean reports go to the manager with a one-line summary. Flagged lines go to a finance reviewer with the evidence and the policy clause that applies.
6. Approved reports post to the ERP with GL and department coding, and findings feed a monthly view by rule, team and merchant.
7. Every check, flag, override and approval is logged with who decided and why.

## What changes for the team
- **Expense auditor or AP specialist.** Today: Opens receipts one by one for a small sample and emails employees with questions. Done for you: Reviews only flagged lines with the evidence laid out, and tunes rules that flag too much or too little.
- **Approving manager.** Today: Rubber-stamps reports in the app without time to check anything. Done for you: Approves clean reports from a short summary and sees flagged items explained in plain English.
- **Controller.** Today: Finds policy problems in the annual audit or after a complaint. Done for you: Reads a monthly findings report and adjusts policy where the data shows a pattern.

## KPIs we measure
- **Audit coverage:** Expense lines checked by the agent compared with lines submitted, reported monthly.
- **Time to reimburse:** Days from submission to payment for clean reports, baselined from your expense tool for the prior quarter.
- **Flag precision:** Share of flags a reviewer confirms as real issues, used each month to tune the rules.
- **Violations by rule and team:** Count of confirmed findings grouped by policy rule, department and merchant.
- **Spend corrected before payment:** Value of lines rejected, reduced or recoded after a flag, totaled monthly.

## Systems it connects to
SAP Concur, Expensify, Ramp, Brex, Navan, Emburse, NetSuite, QuickBooks Online, Workday, Slack

## Guardrails
- The agent never rejects a report or withholds money on its own; it flags with evidence and a person decides.
- Policy rules are written with finance and HR and change only through an approved update.
- Receipts and personal data stay in your systems with role-based access.
- Patterns that may point to misconduct go only to named finance leaders, not to the employee's manager.
- Every flag, override and approval is logged for audit.

## What teams say about this work
- In a survey of US business travelers, most said they felt like they were floating a loan to their employer, and many had skipped claiming a business expense just to avoid filing the report. ([Travel Market Report (TriNet and Wakefield Research survey)](https://travelmarketreport.com/articles/Worse-than-Death-and-Taxes-Filing-Expense-Reports-Says-Study))
- Reviewers of a widely used expense tool describe a layout that is not always intuitive, extra clicks for simple tasks, and approvals that can be slow. ([Capterra](https://capterra.com/p/380/Concur-Expense/reviews/))
- Users of another popular expense app mention duplicated expenses and say approval workflows could be more flexible. ([Capterra](https://capterra.com/p/97594/Expensify/reviews/))
- Fraud found through passive means can take far longer to surface than fraud caught by active methods such as automated monitoring and internal audit. ([Emburse (summarizing the ACFE 2024 report)](https://www.emburse.com/blog/finance-fraud-and-frustration-key-findings-from-the-acfe-2024-report))

## Frequently asked questions
### How long does it take to go live?
Expense audit automations are usually live in 3 to 6 weeks. We turn your written policy into rules with your finance and HR leads, connect the expense tool, card feeds and ERP, and then run the agent over a few months of past reports. That replay shows you what it would have flagged, so you can tune thresholds before it touches live reports.

### What will this cost us?
We quote after a short scoping call. The quote depends on report volume, the expense and card platforms involved, how many countries and currencies your policy covers, and whether you want ERP posting and coding as well as the audit. You receive a fixed written quote covering design, build, connections, deployment and configuration before work begins.

### Does it replace Concur, Expensify or Ramp?
No. Your employees keep submitting expenses in the tool they already use. The agent sits behind it, reading reports as they are submitted and writing its findings back as comments or flags, or into a review queue. Built-in policy checks in those tools usually test single fields; the agent reads the receipt itself and compares across reports and people.

### Will employees feel watched?
Most notice the opposite: clean reports are approved and paid sooner because nobody has to sample them by hand. When a line is flagged, the employee sees a clear, polite question with the policy clause, not an accusation. Possible misconduct is routed only to named finance leaders. We help you announce the change so expectations are clear from day one.
