What is different about expenses in law firms?
Client costs must land on the right matter to be recovered at all, and trust-accounting rules make miscoding a compliance problem, not just an accounting one. That is the test any expense tool has to pass here — not the demo, the month-end.
How does matter-based billing work with company cards?
Vergo reads your clients and matters from your accounting system and codes every expense to the right client and matter the moment a transaction lands. Vergo proposes the coding by inference from your own accounting structure and history — no rule library to build, no keyword lists to maintain, and new vendors are coded on first sight, and every coding shows why it was chosen, so a reviewer confirms in seconds instead of re-coding by hand. Approval workflows are optional and fit how you already control spend: route by GL account, by amount, or by project — or skip approval flows entirely and let policy flags catch only what breaks a rule.
What does the AI read — the receipt, or just the transaction?
Both. The card feed gives the vendor and the amount; the receipt gives what was actually bought. Vergo reads the receipt itself, line by line, and predicts the coding from what was actually bought — the client, the matter and the expense category — not just the vendor name on the header. That is the difference between OCR and AI-native coding: OCR reads the header and hands the cost coding back to a person.
Which systems does it work with?
The systems law firms finance teams actually run: Actionstep, Aderant, Elite 3E, Centerbase, LexisNexis Juris, MyCase Accounting among them — plus the horizontal ledgers (QuickBooks, Sage, NetSuite). Vergo syncs to each in its own structure; see the integration pages for the specifics.
Do we have to change cards?
Vergo's answer is no — it connects to the cards a law firm already holds, fuel cards included, and connecting your existing cards involves no card applications, no re-issuing and no banking change.
One coding model for cards, reimbursements and AP
Card spend, employee reimbursements and supplier invoices are the same coding problem wearing three coats. Vergo runs all three through one model — captured, coded, approved, synced — and payment stays on the rails you already use.
Where should you go next?
What is the best expense management software for law firms?
The one that fits how law firms actually accounts for spend — clients and matters first and works with the cards you already have. Vergo is built as exactly that: AI-native, card-agnostic, with reimbursements and AP in one model.
Can expenses be coded to clients and matters automatically?
Yes — Vergo codes every expense to the right client and matter by inference against the structure it syncs from your accounting system, and shows its reasoning for review.
Does the AI read receipt line items to work out the coding?
Yes. Vergo reads the receipt itself, line by line, and predicts the coding from what was actually bought — the client, the matter and the expense category — not just the vendor name on the header — then every coding shows why it was chosen, so a reviewer confirms in seconds instead of re-coding by hand.
Can a law firm keep its existing corporate cards?
Yes. Vergo is card-agnostic: it connects to existing cards rather than issuing new ones.
Does Vergo handle AP invoices for law firms?
Yes — captured, coded, approved and synced through the same model as card spend. Payment itself stays on your existing rails.
