Cards swipe → receipts get captured → AI categorizes against your chart of accounts and flags policy violations before they hit the close.
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.
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.
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.
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.
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.
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).
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.
Categorized transactions flow into QuickBooks / Xero / NetSuite each night. Month-end becomes a review, not a reconstruction.

Get a new AI workflow every week. Prompts, tool stacks, and ROI math included.
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.
