The AI agent for accounts payable specialists
Sauna reads incoming invoices, matches them to POs and receipts, drafts the payment batch, and writes the vendor reply so coding and approvals are ready before anything hits the payment run.
What it does
What Sauna does for accounts payable specialists
- 01
Three-way match
Sauna pulls the invoice, purchase order, and receipt from the AP inbox and Google Drive, matches quantities and prices in QuickBooks, and flags every mismatch or duplicate for review.
- 02
Code and route invoices
It assigns GL accounts and cost centers from your coding rules, drafts the approval request to the budget owner in Slack, and holds the invoice until they sign off.
- 03
Build the payment batch
Sauna assembles approved invoices into a payment run in Google Sheets by due date and terms, highlights early-pay discounts about to lapse, and waits for your release.
- 04
Answer vendor inquiries
It reads the vendor's email, looks up the invoice and payment status, and drafts the reply with the check date or the reason for a hold, ready for you to send.

Good to know
Questions, answered.
Will it pay vendors automatically?
No. It matches, codes, and builds the batch, but the payment run is released by you. It never sends money or transmits a file without your approval.
Can it catch duplicate or inflated invoices?
Yes. It compares each invoice to the PO, receipt, and prior payments and flags duplicates, quantity or price mismatches, and missing approvals rather than passing them through.
Is my data safe?
Sauna reads only what you connect, and acts only after you approve. Your workspace and its memory are yours, not training data.
