AP automation that works with Unit4

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 Unit4, 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 Unit4?

Vergo works with Unit4 in both directions: it reads your job structure out, and coded card spend, reimbursements and AP invoices go back in. However Unit4 is run — on your own servers or hosted — connecting it is our job, not a project for your team. Vergo reads your projects and phases from Unit4, codes against it, and posts back coded entries — so what lands in Unit4 is already costed to the right work rather than a lump for someone to break up at month end. The Unit4 API exposes Imported Expense, Travel expenses, Financial Transactions, Incoming Invoices, Supplier and Supplier Transactions — object names from Unit4's developer documentation, not inference. New projects and phases appear as they are created, so the field is never choosing from a stale list. The same connection carries all three products — see everything Vergo does with Unit4 — and the full spec sheet lives on the Unit4 integration page.

What does this actually look like day to day?

Someone in the field buys materials and sends a photo of the receipt. Vergo reads the lines — not just the total — and proposes the projects and phases they belong to, along with the cost type. If one receipt covers two jobs, it splits. The reviewer sees the proposal and the reason for it, confirms, and the entry is in Unit4 the same day. Nobody types a code, and nothing waits for a weekly expense report.

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 Unit4 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 Unit4 and reimbursements and expense reports for Unit4.

Who runs Unit4?

Unit4 is run by mid-market companies across industries. The former Agresso; services and public sector. 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.
