AP automation that works with Karmak Fusion

What makes AP automation AI-native?

AI-native AP automation reads the invoice as a document rather than as a template. It infers the coding from the line items and from the structure and history of your own accounting system, so an invoice from a supplier nobody has set up, in a layout nobody has mapped, is coded on first sight — instead of falling into an exception queue for a person to key. What it reads is the invoice document, line by line, including its line items and their descriptions. The difference shows up on the first transaction from a supplier nobody has set up. A rules engine has no pattern for it, so it queues the item and waits for a person. Vergo reads what was actually bought and proposes the coding from the structure already in Karmak Fusion, then shows why it chose it — so the review is a confirmation, not a re-coding. More on the category in AP automation.

How does it work with Karmak Fusion?

Vergo reads your chart of accounts from Karmak Fusion, codes against it, and posts back coded entries — so what lands in Karmak Fusion is already coded to the right account rather than a lump for someone to break up at month end. The Karmak Fusion API exposes Create Journal Entry API and AP Invoice create API — object names from Karmak Fusion's developer documentation, not inference. New accounts appear as they are created, so nobody codes against a stale chart. The same connection carries all three products — see everything Vergo does with Karmak Fusion — and the full spec sheet lives on the Karmak Fusion integration page.

What does this actually look like day to day?

Someone buys something and sends a photo of the receipt. Vergo reads the lines — not just the total — and proposes the account, department and class from your own history with that vendor. The reviewer sees the proposal and why it was chosen, confirms, and the entry is in Karmak Fusion the same day. Nobody types a code, and nothing waits for a month-end scramble.

Does Vergo pay the invoice too?

Vergo captures, codes, approves and syncs invoices; it does not pay them. Payment stays on the rails the business already uses — its bank, its card, its existing payment provider. A team looking for AP automation that also moves the money is better served by a platform built to do both.

What changes at month end?

The work moves from the end of the month to the moment of spend. Because coding happens at capture and syncs to Karmak Fusion as it goes, close is a review of exceptions rather than a backlog of uncoded transactions. Every coding shows why it was chosen, so a reviewer confirms in seconds instead of re-coding by hand, which is what makes a reviewer able to move quickly through it. Card spend, employee reimbursements and AP invoices run through one coding model — same coding, same review, one reconciliation — and payment stays on the rails you already use.

Is this the same as reimbursements?

The difference is whose money was spent. Expense management handles the company card; reimbursement handles an employee's own card or cash. The same coding model runs both, which is why one reconciliation covers them — but a business shopping for one is rarely shopping for the other. If you are looking at the other side of that line, see expense management for Karmak Fusion and reimbursements and expense reports for Karmak Fusion.

Who runs Karmak Fusion?

Karmak Fusion is run by mid-market companies in auto dealers. If your finance team lives in it, the expense layer should adapt to it — not the other way round. Vergo integrates with every ERP and accounting system, so the answer does not change if you move.
