Expense coding and policy review agent

An agent codes each card transaction and invoice line to your GL, checks it against policy, approves low-risk items and escalates anything ambiguous, and answers employees' "can I expense this?" by text.

Building block of the Finance ops agent.

1Is this my problem?

Coding and policy checks are high-volume and rule-heavy, a good fit for an agent that knows when to ask.

You'll recognise this if…

Month-end coding marathon.
Missing receipts.
Out-of-policy spend caught late.

Companies affectedCompanies with 30+ card holders. Typical fit: 10 staff to 50 staff.

Cost of doing nothing (estimate)Roughly 5–15 hours a week of manual work stays on the team, and the work is done inconsistently.

2Is this solution worth it?

Reported results

Ramp reports 90% of transactions auto-coded and a 75% reduction in card reconciliation time for customers (source)

Limits and when not to build it

Skip it if: Few transactions.

No money should move without human confirmation (Ramp states this explicitly).

3How does it work?

One small internal tool does this for you. The same job, before and after:

Before · by hand

Card transaction / invoice: someone notices
Extract receipt + line items
Code to GL from past patterns (by hand)
Policy check
Auto-approve low risk
Escalate risky ones

Maturity ladder

What each level adds. Most teams start at level 1 or 2 and climb. Highlighted: where this build sits.

Level 1Basic automation
Trigger: card transaction / invoice. Fixed rules then extract receipt + line items, policy check, auto-approve low risk. No AI involved.
Level 2AI-assisted
An LLM handles the judgement step (code to gl from past patterns) and a person reviews every output before it is used.
Level 3Autonomous agent
The agent runs end to end on its own and only stops for exceptions. Humans approve payments and risky spend.
Level 4Self-learning system
Becomes part of the finance ops agent: Reviewer corrections to coding become examples for the next run, so auto-coding accuracy rises over time.

Level 4 lives in the Finance ops agent: 6 stages with a learning loop.
