What this is
A real workflow someone ran with an AI agent. Copy the prompt into your agent, connect the listed tools, and it runs for you.
- Copy the prompt below.
- Paste it into your agent (we recommend Grok Bot) and connect the tools listed: whatever the prompt mentions.
- Run it once, check the result, then put it on a schedule if it repeats.
What you get
Code handles predictable invoice lines, Claude handles tricky negative items, structured parsers output to Sheets, and project names are fuzzy-matched to an internal API.
The prompt
Cleaned version rewritten from the source — not a direct quote.
For each invoice PDF: extract standard positive line items with code; send negative or ambiguous line items to Claude with a strict JSON schema; validate totals; fuzzy-match project names to existing records; write to Google Sheets and update [API].
Recommended
Try it in Grok Bot
- Copy the prompt (button below).
- Open Grok Bot chat and paste it. Replace any [bracketed] placeholders.
- Connect the listed tools (as needed) as connectors when Grok Bot asks.
- If the task repeats, ask: “Make this a daily routine.”
Alternatives: the same prompt works in n8n, Claude, ChatGPT Agent, OpenClaw.
Set it up

Pitfalls & reliability
- Good hybrid pattern (code first, AI where needed).
- Reddit blocks automated access from our network; this post was not independently re-checked. Figures come from search snippets of the post.
Evidence
Good hybrid pattern (code first, AI where needed). Marketing check: PASS: consultant sharing client work, no funnel link. Duplicate check vs agentusecases.ai: POSSIBLE DUPE: extract-vendor-pdfs-and-create-quickbooks-invoices
