# QuickBooks vendor invoice automation

Claude Code upgraded the author's existing QuickBooks Online integration to attach original PDFs, self-update the item list, clean up files, and skip duplicate invoices.

Result: A test run processed 40 PDFs, created the QuickBooks records, attached the PDFs, and cleaned up automatically, cutting hours to minutes.

## How it was set up

Claude Code opened on the existing custom QuickBooks Online integration, using the QuickBooks attachment API alongside the existing invoice-creation logic.

## Worth knowing

The system still asks the author to pick a category when it meets a new, unseen product.

## Prompt

```text
Open my existing [vendor] QuickBooks integration. Add attachment of the original PDF to each created invoice using the QuickBooks attachment API, skip invoices that already exist, and delete the local PDF and temp CSV after success. Leave the invoice-creation logic unchanged.
```

## Evidence note

Author states 40-PDF test run and shows a video walkthrough; no repo
