Invoice + Receipt Extractor

A Gmail label or Drive folder triggers the run. LlamaParse extracts text from the PDF (handles tables, multi-column, bad scans). Claude Sonnet returns a strict schema: vendor, invoice number, date, subtotal, tax, total, currency, line items. A QuickBooks bill is created against the vendor record (or the vendor is auto-created); line items map to the right expense accounts via a lookup table you own. An audit row lands in Notion with the original PDF attached. Month-end reconciliation drops from 6 hours to 20 minutes.

Every layer is swappable · the architecture is not

What it does

Every receipt or invoice hits a Gmail label (#receipts) or a Drive folder. LlamaParse extracts the raw text · it handles tables, multi-column layouts, and genuinely bad scans where lesser parsers give up. Claude Sonnet turns the raw text into a strict JSON schema: vendor, invoice_number, date, subtotal, tax, total, currency, line_items.

A QuickBooks bill is created against the vendor record (or the vendor is auto-created if it is new). Line items map to the right expense accounts via a lookup table you own and control. A Notion audit row lands with the original PDF attached so the trail back to the source is always one click away.

Month-end reconciliation drops from six hours to twenty minutes. Your accountant stops chasing you for missing line items at quarter close.

Real-world use cases

Who actually uses this, and what changes for them.

Agency owner reconciling 80+ vendor invoices a month

Every month-end you spend two full days in QuickBooks typing invoice details from PDFs someone forwarded three weeks ago.

Before

Receipts live in six different places: the shared Drive, personal Gmails, WhatsApp forwards, Dropbox. You hunt for them at close and manually type line items. Some always get missed.

After

Every receipt hits the Gmail #receipts label or the Drive folder. The workflow parses, classifies the expense account, posts to QuickBooks, and drops an audit row in Notion with the PDF attached. Close compresses from 2 days to 90 minutes.

Solo founder allergic to accounting

You avoid QuickBooks for three months at a time, then pay a bookkeeper $800 to sort the pile at year-end.

Before

Your shoebox of receipts is a Gmail label with 180 PDFs you never open.

After

The shoebox auto-files itself. Year-end bookkeeping drops from 8 hours of catch-up to 20 minutes of review.

Operations lead at a 20-person services firm

Contractor invoices come in from 12 different freelancers with 12 different formats. Approving and paying them is a weekly 3-hour ritual.

Before

Someone manually opens each PDF, checks the amount against the contract, types the data into QuickBooks, and slacks the approver.

After

LlamaParse + Claude extracts every field including line items and hours. Anything above $500 or outside the contract rate gets a human-review flag. Everything else posts straight through.

What changes for your team

  • Nobody on your team types invoice data anymore.
  • The expense-account mapping lives in a lookup table your team owns, so if accounting says "code this to marketing software" you change one row.
  • The audit trail always leads back to the original PDF, one click away.
  • The accountant stops asking clarifying questions at close.

Gmail AI Triage + Draft Reply

Gmail push-notifies on every new message. Claude Haiku classifies in 400ms into one of 7 labels (client, sales-inbound, sales-outbound-reply, vendor, admin, newsletter, noise). Haiku applies the label, then drafts a reply in your voice (fine-tuned on your last 200 sent emails) as a Gmail draft inside the thread. If urgent, a Slack DM fires. Inbox-zero becomes a 15-minute review job, not a 2-hour typing job.

Brief Generator

A client completes your 12-question Typeform. n8n catches the submit, validates required fields (if missing, the client gets a clarifier email, not a broken brief). Claude Sonnet transforms raw answers into your house brief structure: objectives, audience, deliverables, timeline, success metrics, constraints. Output writes to Google Docs via the Docs API using your master template. A Slack thread opens in #briefs with three sign-off checkboxes. On approval the doc moves to the client folder and a ClickUp project is created. Lead-to-kickoff compresses from 4 days to same-day.

Prospect Research + Send

A webhook takes a LinkedIn URL or email. Perplexity pulls 90 days of company news, funding, and headcount shifts. Claude Sonnet scores against your ICP JSON and writes a 3-sentence opener referencing one specific signal. Smartlead queues the email at 9:45am local; Expandi fires the LinkedIn touch 36 hours later. End-to-end: under 3 minutes per prospect.
