Receipt Categorization & Expense Policy Enforcement

Cards swipe → receipts get captured → AI categorizes against your chart of accounts and flags policy violations before they hit the close.

The Problem

Employees forget receipts, controllers chase them, and out-of-policy spend gets discovered three weeks after the fact. The modern fix is to push intelligence to the swipe: corporate card platforms (Ramp, Brex, Mercury) categorize transactions at the time of charge, prompt the employee for the receipt by SMS within minutes, and apply policy rules automatically. AI reduces expense processing tasks 50-70% in the first year and eliminates most policy violations before they become reconciliation pain.

Workflow Steps

1

Issue corporate cards through Ramp / Brex / Mercury

Replace personal-card-then-reimburse with corporate cards for every employee who spends. The whole categorization story depends on this — receipts-after-the-fact never work.

2

Write your expense policy in plain English

Per-diem caps, allowed categories per role, vendors that require pre-approval, max receipt-less amounts. Keep it under one page. Upload it to the platform as the source-of-truth.

3

Map policy rules to platform controls

Card-level: vendor category restrictions (no gambling, no crypto), per-transaction cap, per-month cap. User-level: which spend categories they can authorize. The platform enforces in real time at the merchant level.

4

Configure AI auto-categorization

Most platforms ship with default GL mapping. Tune it: which transactions go to 'travel — flights' vs 'travel — meals'. Approve auto-categorization for the top 50 vendors so it goes straight to the GL without human touch.

5

Set receipt capture rules

Auto-prompt employee by SMS within 5 minutes of a swipe over $25. Pull receipt OCR. If no receipt within 24 hours, flag for human review. Force employees to comment on out-of-pattern spend (>2x median for that category).

6

Run a monthly anomaly review

Have the controller spend 30 minutes/month on platform-surfaced anomalies: unusual vendors, off-pattern spend, missing receipts. The AI surfaces 5-15 items in a typical SMB month.

7

Sync to the GL nightly

Categorized transactions flow into QuickBooks / Xero / NetSuite each night. Month-end becomes a review, not a reconstruction.

Copy-Paste Templates

Use these templates as-is or customize for your business.

Expense Policy Template (One Page)
EXPENSE POLICY — [Company]

1. Use corporate cards only. No personal-card-then-reimburse.
2. Per-diem caps: meals $75/day domestic, $100 international. Lodging at posted city max.
3. Pre-approved categories: software, travel, meals with clients, office supplies.
4. Require pre-approval (any amount): consulting, agency fees, hardware >$500.
5. Receipts: required for all transactions $25+. Capture via platform SMS within 24h.
6. Personal expenses: zero tolerance. Will be charged back to employee.
SMS Receipt Capture Template
Hi {{name}}, please add a receipt for your ${{amount}} purchase at {{merchant}}: {{capture_link}}. Reply to this message with the receipt photo or upload via the link. Required within 24h.
Anomaly Review Checklist (Monthly)
[ ] Vendors never seen before (>$200)
[ ] Spend >2x median in category for user
[ ] Missing receipts past 48h
[ ] Weekend personal-looking categories on corporate card
[ ] Multiple round-number transactions same vendor (potential gift card abuse)

When NOT to Use This

Skip if you have fewer than 3 card users or your spend volume is under $5K/month. Skip if you operate on reimbursement-only by policy (regulated industries). Reimbursement-only flows lose most of the AI advantage.
