How do AI Employees process invoices the moment they land?

An accounts payable AI Employee that pulls new invoices from the inbox, extracts vendor, amount, and line items, matches them against POs and the ledger, and routes each one to a named human for approval. It never schedules or marks a payment itself.

Problem

Vendor invoices arrive by email all day, on no schedule anyone controls, and each one needs the same handling: open the attachment, read off the vendor, amount, and line items, check it against the purchase order, check it isn't a duplicate of something already in the ledger, and check the price is what was agreed. By hand that's five careful minutes per invoice, and those five minutes are where duplicates and overcharges slip through, not from carelessness but because checking against every prior invoice and every open PO doesn't scale to an afternoon. The usual shortcuts don't fix it. Paying on receipt catches nothing. A monthly batch review catches duplicates and overcharges after the fact, sometimes after the payment has already gone out. Neither checks every invoice against every PO and every prior invoice at the moment it arrives.

What it does

Every 15 minutes the accounts payable AI Employee checks the inbox for new invoice emails, extracts the vendor, amount, and line items from each attachment, matches it against the known POs and prior invoices in the ledger, flags anything that's a duplicate, an overcharge, or missing a PO, and records every invoice. It then posts the batch for a named human to approve. It never schedules a payment or marks anything paid.

How it works

See exactly how the work gets done.

Runs every 15 minutes against the ledger

A scheduled run fires every 15 minutes. Each run starts clean. The ledger is the record, not the AI Employee's memory, so duplicate and overcharge checks are judged against the same book of truth every time.

Carries your AP rules

What counts as a duplicate, the tolerance before a line item is an overcharge, and what to do when no PO matches at all travel with it as a skill, so it works to your standard instead of improvising invoice by invoice.

Connects to what AP needs, with permissions you set

It reads new invoice emails and attachments, reads and appends to the POs and AP ledger it matches against, and posts the processed batch, flagged or clean, for approval. Credentials stay in memory, never exposed to the model.

No payment rail, ever

Its only write is an appended ledger row and the approval post. It has no access to a payment rail, and nothing in its instructions lets it schedule or mark an invoice as paid. That belongs to a person, every time, with no exception for a clean match.

Routes the batch for a signature

By the time a person looks, every new invoice is already extracted, matched, and recorded, each marked clean, duplicate, overcharge, or missing PO, with the PO and prior invoice references attached. A named human reviews and approves it for payment through your normal AP process.

Guardrails

Runs in your environment

Every run is isolated inside your own infrastructure, reaching only the inbox, the ledger, and the approval channel.

Permissions you set

Email, ledger, and chat credentials stay in memory, injected at run time, never exposed to the model or written to logs.

No payment action, ever

It has no integration, tool, or instruction that schedules a payment or marks an invoice paid. Every invoice, clean or flagged, goes to a named human for that decision.

Flag, don't discard

Duplicates, overcharges, and missing PO invoices are recorded and flagged, never silently dropped or automatically approved.

You own the rules

The matching rules, tolerances, and permissions are yours, versioned and changed on your terms, not in a vendor dashboard.

The outcome

The five careful minutes an invoice used to wait for now happen automatically, every 15 minutes, against the full history in the ledger rather than whatever a person remembers. What used to reach the payment step unchecked now arrives flagged, with the conflicting PO or prior invoice already attached, and the decision to pay stays exactly where it belongs: with a person.
