An AI Receipt Logger for n8n and Zapier

By: Miimu Staff Last updated on October 25, 2026

Receipts arrive by email all week, and someone has to copy the vendor, date and amount into a spreadsheet before the bookkeeping makes sense. It's the kind of job an automation tool and an AI model can share: the tool watches the inbox, the AI reads each receipt, and a row appears in the sheet.

Claude was asked to build that automation for n8n, and again for Zapier. Everything it made is saved in one bundle, next to template galleries and guides for common jobs: inbox, leads, social media and personal admin.

The Prompt That Started It

One request that states the payoff, an hour a week, and lists the four pieces needed to make it run. The test emails, each with its expected row, make the result easy to check.

Build me an automation that saves me an hour a week: when a receipt email lands in my Gmail, pull out the vendor, date, amount and category with AI and add a row to a Google Sheet, then send me a Friday summary. Make each of these as its own separate artifact, and build every one as an HTML web page artifact (not a document) so anyone with the link can open it: 1) the importable n8n workflow JSON on a page with a copy button; 2) a step-by-step setup guide for n8n, including the Gmail and Sheets connections; 3) the same automation as a Zapier zap, step by step, for people who would rather not use n8n; 4) the AI prompt the workflow uses to read receipts, with three test emails and the rows they should produce. Make reasonable assumptions instead of asking me questions.

The first miimu in the bundle links to the full chat, shared from Claude, so anyone can read what went in.

What Came Back

Each of the four pages saves into the bundle as its own miimu.

The n8n workflowNine steps already wired, from new email to Friday summary. Copy the JSON, paste it onto an empty n8n canvas and fill in four settings.

The n8n setup guideEach step from an empty Google Sheet to a running workflow, about 25 minutes, including the Gmail, Sheets and Claude connections and one test email.

The Zapier versionThe same job as two Zaps, for anyone on a paid Zapier plan. It uses Zapier's own AI step, so no separate API key is needed.

The prompt and testsThe exact instructions sent with each email, the answer format, and three test receipts with the rows they should produce.
