# Track bills and invoices with one free prompt

This page gives you a free, copy-ready prompt for this job (it captures new bills and invoices, runs duplicate checks and builds a due-item review queue: vendor, invoice, amount, due date, duplicate check, review status), plus the $19 standing-agent version that runs it on repeat without re-pasting rules.

It captures new bills and invoices, runs duplicate checks and builds a due-item review queue: vendor, invoice, amount, due date, duplicate check, review status. The prompt below is the do-it-yourself version.

## The prompt

    Process these new bills: [paste vendor, invoice number, amount, due date]. Check each against my recorded bills for duplicates by vendor, number and amount: [paste sheet]. Output a review queue with a DUPLICATE CHECK column. Flag suspects, do not delete or pay anything.

## What to bring

Bills arrive by email and post, duplicates slip through, and the due-date surprise is a month-end tradition nobody wants.

## What a good run returns

Vendor, invoice, amount, due date, duplicate check and review status, in a Bookkeepers Bills & Invoices Workspace folder.

## Where the free version ends

A prompt runs when you remember to run it, from whatever context you paste, and it forgets the rules between sessions. The [Bills & Invoices Agent](/bookkeepers/bills-invoices-agent/) ($19 one-time) installs this as a standing workflow: fixed evidence rules, a saved output in your own Drive every run, fictional-data testing before real work, and hard stops before anything sends, spends or publishes.
