Prompt objective
Build an end-to-end accounts payable automation that eliminates manual data entry for vendor invoices.
Real use case
A mid-size company processes 500+ vendor invoices monthly. Each takes 15 minutes to manually enter into QuickBooks, costing 125 hours/month in AP team time.
Customize these fields first
Replace the placeholders with your own context before you run the prompt. That usually improves the first output more than adding more instructions later.
Prompt
Act as a finance automation specialist. Design an n8n workflow for [COMPANY NAME] that automates the entire invoice processing pipeline.\n\n**Context:**\n- Monthly invoice volume: [NUMBER]\n- Primary vendor count: [NUMBER]\n- Accounting system: [QUICKBOOKS/XERO/OTHER]\n- OCR service: [GOOGLE VISION/AWS TEXTRACT/OTHER]\n- Average invoice value: [AMOUNT]\n\n**Deliverables (numbered):**\n1. Email trigger setup: IMAP node configuration, attachment filtering (PDF only), deduplication by filename hash\n2. OCR extraction pipeline: image preprocessing, field extraction (vendor name, invoice number, date, line items, total, tax), confidence threshold handling\n3. Purchase order matching: fuzzy match vendor name, exact match PO number, tolerance rules for amount variance (+/- [PERCENTAGE]%)\n4. Approval routing: if amount > [THRESHOLD], route to [APPROVER ROLE] via email with approve/reject links\n5. Accounting entry creation: line-item mapping to [ACCOUNTING SYSTEM] chart of accounts, tax code assignment\n6. Exception handling: low-confidence OCR results, unmatched POs, duplicate invoice detection\n7. Dashboard metrics: processing time per invoice, exception rate, total value processed monthly\n\n**Constraints:**\n- Must handle multi-currency invoices\n- Must store original PDF in [CLOUD STORAGE] with metadata\n- Must comply with [TAX JURISDICTION] retention requirements
