Accounts Payable

# Every supplier invoice checked before it's recorded.

Our AP Agent reads invoices as they reach your AP inbox, checks each one against the vendor, the purchase order and the ledger, and records it once your team approves. It never pays.

 An illustration of the AP Agent matching an accounts payable invoice against its purchase order and receipt, finding one line the order never covered, and proposing the amendment for approval.

What it does

## The checks your AP team runs by hand, on every invoice.

- ### Invoices from the inbox
Reads PDFs, scans and invoices typed into the email as they arrive. No email is worked twice.
- ### Checked against the ERP
Confirms the vendor exists and isn't blocked, the purchase order is theirs with room left, and the currency matches.
- ### Duplicates and fraud signs
Catches an invoice that's already been entered, and flags lookalike senders and changed bank details.
- ### Arithmetic, to the cent
Re-adds every line and total. A check it couldn't run is reported as not checked, never as a pass.
- ### Recorded once approved
Creates the bill as a draft, reads it back, and posts it only after your team approves each step.
- ### Period-end AP reviews
Reviews AP aging for unrecorded liabilities, vendor credits and prepayments, and employee and card spend.

How it works

## From the inbox to the ledger, on your approval.

Our AP Agent does the checking. Your team decides what gets recorded, and paying stays with you.

1. ### An invoice arrives
It's picked up from the AP mailbox and read, scanned or not.
2. ### The agent checks it
Vendor, duplicates, purchase order, currency and arithmetic, with anything it couldn't check said plainly.
3. ### Your team reads the result
A clean invoice is ready to record. A flagged one leads with what failed and why.
4. ### Approve, and it's recorded
The bill is drafted, checked, then posted, each step on an approval. Payment stays with your team.

Works with your stack

## Reads your inbox and ERP. Records only what you approve.

Invoices come in through Gmail or Outlook, and our AP Agent records the bills you approve in your ERP, from Business Central to NetSuite and SAP S/4HANA, across BILL, Ramp and Brex.

Questions

## The questions we get asked first.

- ### Do you pay invoices?
No. Our AP Agent checks invoices and records them once approved; payment stays with your team. It doesn't reply to vendors or send email either.
- ### Which systems do you work with?
We read invoices from Gmail or Outlook and record approved bills in your ERP: Business Central, NetSuite, SAP S/4HANA, QuickBooks or Odoo. BILL, Ramp and Brex connect too.
- ### What if an invoice can't be read, or a check can't run?
Our AP Agent says so. An unreadable file, or a check it couldn't complete, is reported as not checked and never counted as a pass.
- ### Who approves what gets recorded?
Anyone with approval rights except the person who asked for it. Each approval covers that exact bill and can only be used once.
