Automatically extract, categorise and organise receipts using a fully AI driven bookkeeping workflow.
A fully automated bookkeeping system that extracts receipt data, assigns accurate categories, and syncs every transaction into both Notion and Xero with no manual entry. Users gain a clean AI enriched ledger, automatically attached receipt files, consistent categorisation, and weekly financial summaries, resulting in faster bookkeeping, fewer errors, and a complete audit ready workflow that runs on its own.
Create a Notion database called Bookkeeping Ledger with properties such as date, merchant, amount, currency, category, payment method, notes, receipt image link, Xero status and any custom tags you need.
Set up your preferred receipt intake method, such as saving images to a cloud folder or uploading via a form or email, and configure n8n to trigger a workflow whenever a new receipt file is added.
In n8n, add a node that grabs the new receipt file, stores its URL or attachment reference and passes it to Relevance AI for OCR and structured data extraction.
Configure Relevance AI to read the receipt image or PDF and extract fields such as date, total amount, tax, merchant name, line items and detected currency into a structured JSON object.
In n8n, clean and map the Relevance AI JSON into standard fields like merchant, amount, date, tax, currency and raw description so that each value is clearly defined.
Add an n8n node that sends this structured data along with your Xero chart of accounts or custom category rules to Claude and ask it to assign an expense category, validate the totals and flag any potential issues.
In the same Claude prompt, request a short natural language summary of the receipt that explains what was purchased, why and whether it appears to be a business or personal expense.
Map Claude's response back into fields such as category, subcategory, summary, business or personal flag and any warnings, then combine those with the extracted numeric fields from Relevance AI.
Use an n8n Notion node to create a new row in your Bookkeeping Ledger database with all extracted and generated fields and attach or link the original receipt image for reference.
Add an n8n Xero node that takes the same structured data and creates a new spend money transaction or bill in Xero with the correct date, amount, merchant, account code and attached receipt file.
After Xero confirms creation, update the matching Notion ledger row via n8n with the Xero transaction ID and set the Xero status field to Synced so you always know which entries are in your accounting system.
Configure a scheduled n8n workflow that once a week queries Notion or Xero for new entries and sends a batch summary into Claude to generate a short financial overview, then store that overview back in Notion so you can refine your category rules and prompts over time.

This blueprint builds a complete AI bookkeeping system that reads your receipts, extracts the important details and organises everything into a structured financial record. The system uses Relevance AI to extract data, Claude to validate and categorise it, Notion to store a human friendly ledger and n8n to automate the entire workflow. The blueprint also supports Xero integration, which allows all processed receipts to appear directly inside your accounting software with categories, totals and attachments already filled in.
The workflow begins with a Notion database that acts as your finance dashboard. This database includes fields for receipt date, amount, tax, merchant, category, notes and the original receipt file. It gives you a clear, organised view of all processed transactions. Businesses that use Xero can keep Notion as the AI enrichment layer while Xero remains the official accounting source of truth.
When you upload a receipt into your intake method, such as a cloud folder or a simple form, n8n immediately detects the new file. n8n retrieves the receipt, stores its reference and sends the file to Relevance AI for extraction. This creates a smooth, hands free workflow that removes the need for manual data entry or sorting.
Relevance AI reads the receipt and extracts structured fields such as merchant name, transaction date, total amount, tax amounts, currency and line items. It outputs a clean JSON object that transforms a raw document into accurate financial data. n8n then maps this extracted information into standard fields that Claude can work with.
Next, n8n sends the structured fields and your chart of accounts or category rules to Claude. Claude reviews the extracted data and assigns an appropriate category based on real financial reasoning. Claude checks if the numbers make sense, identifies tax patterns and creates a short summary of the purchase that explains what was bought and whether the expense appears personal or business related. This improves accuracy, especially with messy or unclear receipts.
After Claude finishes processing, n8n combines the extracted fields with the categorised output and creates a new entry in Notion. Each entry includes the raw numbers, the assigned category, the summary and a link to the receipt image. This turns Notion into a clear, readable ledger that can be filtered by month, category or merchant. If you prefer, you can also configure n8n to skip Notion and send everything straight to Xero.
For businesses using Xero, n8n can create new spend money transactions, attach the receipt image and assign the correct account code based on Claude’s decision. Xero’s API allows you to upload the receipt file and attach it to the transaction so every expense is audit ready. n8n can also fetch your Chart of Accounts from Xero and confirm that Claude selects a valid category every time. This creates a fully automated loop where receipts flow from upload to Xero with no manual input.
You can also set up optional workflows. n8n can detect similar receipts over time and suggest marking them as recurring. You can schedule a weekly or monthly process that gathers all entries and sends them to Claude to generate a financial summary that highlights spending patterns, anomalies or category breakdowns. These summaries can be stored inside Notion for review or pushed into Xero notes for accountants.
Over time, you can refine the Claude prompts and category rules inside n8n to improve precision. As more receipts flow through the system, the workflow becomes stronger at categorising merchants, understanding context and identifying patterns.
The final result is a complete AI powered bookkeeping engine that eliminates manual entry, keeps your receipts organised and ensures that both Notion and Xero remain accurate and up to date. It is a fast and reliable way to automate bookkeeping without complexity or traditional data entry work.
