What does the AI invoice processing agent do?

It watches your Gmail inbox for invoice PDFs, extracts the vendor, invoice number, dates, line items, and totals from each one, validates the numbers, appends a row to your Google Sheet, and posts a summary to Slack. It handles the whole flow from inbox to ledger without manual data entry.

Can it fully automate invoice processing?

Yes. With a Gmail trigger connected, it runs automated invoice processing end to end: it detects each new invoice email, extracts the data, validates the numbers, logs the invoice to your Google Sheet, and posts a summary to Slack, with no manual step in between.

Can it read scanned or photographed invoices?

Yes. It uses Reducto for extraction, which handles both digital PDFs and image-based ones with OCR, so a scanned bill or a phone photo of a paper invoice is processed the same way as a clean export from accounting software.

How does it validate an invoice?

It confirms the required fields are present, checks that the line items sum to the subtotal and that subtotal plus tax equals the total, and flags an invoice as overdue if the due date has already passed. Each invoice is marked passed or flagged, with the reason recorded when something is off.

Where does the data get logged?

Every invoice is appended to a Google Sheet you choose, with columns for vendor, invoice number, date, due date, currency, subtotal, tax, total, line items, status, and issues. If the sheet has no header row yet, the agent writes one first.

Does it handle invoices in different currencies?

Yes. It extracts and preserves the currency on every invoice, logs the currency code in the sheet, and shows the matching symbol when it reports an amount, so dollar, euro, and pound invoices stay distinct in your ledger.

Can it process invoices automatically as they arrive?

Yes. You can set up a Gmail trigger that watches for invoice emails and processes each one as it lands, so the ledger stays current and the team gets a Slack summary without anyone checking the inbox.

Instructions it follows

Show the data before loggingDisplay the extracted vendor, amounts, and dates so the user can catch an issue on screen before anything is written to the ledger.
Validate before you recordCheck the required fields, confirm the line items and tax add up to the total, and flag anything overdue instead of logging it silently.
Default to actionWhen the user says to process their invoices, start searching the inbox right away instead of asking for confirmation first.

Try asking

Set up invoice processing: watch my Gmail for invoice PDFs, extract the data, validate it, log it to Google Sheets, and notify me on Slack.
Check my Gmail inbox for any new invoice PDFs and process them.
Create a Gmail trigger that watches for invoice emails and processes them automatically when they arrive.
Pull all processed invoices from my Google Sheet and show me a summary of total spend by vendor this month.

Stop typing invoices into a spreadsheet by hand

The agent reads every invoice, checks the math, logs it to one sheet, and tells the team, so bills get recorded right and on time.

Without Gumloop

With Gumloop

Without vs. With Gumloop

Someone opens each invoice PDF and retypes the vendor, totals, and dates into a spreadsheet by hand.

The agent reads every PDF and pulls the vendor, invoice number, dates, line items, and totals into structured fields automatically.

A subtotal that does not match the line items, or a tax line that is off, slips through and gets paid anyway.

It checks the math on every invoice, confirms the line items sum to the subtotal and the total, and flags anything that does not add up.

An invoice lands in an inbox, gets buried under other email, and nobody notices until it is past due.

A Gmail trigger catches invoice emails as they arrive, processes them, and posts a Slack summary with the due date so nothing sits unseen.

There is no single record of what was billed, so reconciling spend at month end means digging through threads.

Every processed invoice is appended to one Google Sheet with its vendor, amount, currency, and status, ready to filter and total.

What is the Invoice Processor?

The Gumloop AI invoice processing agent turns a folder of invoice PDFs into clean, checked, logged data. It watches your Gmail inbox for invoice attachments, reads each one, pulls out the vendor, invoice number, dates, line items, and totals, then writes a row to your Google Sheet and posts a summary to Slack. You do not retype anything, and nothing has to leave your inbox to get processed.

It reads both kinds of invoice. Digital PDFs and scanned or photographed ones are both handled, with OCR for image-based files, so a supplier emailing a phone photo of a paper bill is processed the same way as a clean export from accounting software. It captures multiple currencies, preserves the currency on every row, and shows the right symbol when it reports an amount, so a euro invoice and a dollar invoice never get confused.

Every invoice is checked before it is recorded. The agent confirms the line items add up to the subtotal, that subtotal plus tax equals the total, that the required fields are present, and that the due date has not already passed. It marks each invoice as passed or flagged, records the reason when something is off, and can reply to the sender asking for a corrected copy, so a wrong number does not quietly get paid.

What you can do with the Invoice Processor

Workflows the agent handles out of the box.

Reads digital and scanned PDFs

Extracts vendor, invoice number, dates, line items, and totals from clean exports and from scanned or photographed bills, using OCR for image-based files.

Validates the numbers

Checks that line items sum to the subtotal, that subtotal plus tax equals the total, that required fields are present, and flags any invoice that does not add up.

Logs to one ledger

Appends every invoice to a Google Sheet with vendor, invoice number, dates, currency, amounts, status, and issues, writing the header row first if the sheet is empty.

Notifies and follows up

Posts a summary to your finance channel with the vendor, amount, due date, and validation result, and can reply to the sender when an invoice needs to be resubmitted.

Runs on a trigger

Set up a Gmail trigger that watches for invoice emails and processes each one as it arrives, so the ledger stays current without anyone checking the inbox.

Invoice Processor use cases

Real workflows teams run with this agent.

Accounts payable inboxes

Watch a shared billing inbox, process every invoice that arrives, and keep one ledger of vendor, amount, due date, and status the whole team can reconcile against.

Scanned and emailed bills

Turn a supplier photographing a paper invoice or forwarding a PDF into the same clean, validated row as an invoice exported from accounting software.

Multi-currency vendors

Process invoices in dollars, euros, pounds, and yen in one ledger, preserving the currency on every row so totals by vendor and region stay accurate.

Month-end spend reviews

Pull every processed invoice from the sheet and total spend by vendor for the month, with flagged invoices already marked so disputes are easy to find.

Why use Gumloop for the Invoice Processor

Checks before it records

The math, the required fields, and the due date are all validated on every invoice, so a wrong subtotal or a missing number is caught instead of paid.

It shows the data first

Extracted fields are displayed before anything is logged, so you can catch an issue on screen rather than finding it later in the ledger.

One ledger for everything

Every invoice lands in a single Google Sheet with a row per bill, so reconciling and totaling spend is a filter, not a hunt through email threads.

It lives in your workspace

The agent runs inside Gumloop with your inbox and sheet connected, so reading, checking, and logging an invoice is one flow instead of three separate tools.
