n8n Finance Pack (Claude + Slack) — 5 Workflows

This pack bundles five n8n workflows that automate invoice and payment tracking using OCR, AI, and cloud services. Workflows 1 and 5 ingest invoices as PDFs or images, extract data via OCR and Claude AI, and sync with Notion and Slack for approvals and notifications. Workflow 2 monitors email for new invoices, extracts amounts, and sends Slack and email alerts based on value. Workflow 3 uses OCR and AI to extract, validate, and log invoice data into Google Sheets. Workflow 4 parses invoice data from incoming emails using text processing and machine learning. Together, these workflows connect Notion, Slack, Google Sheets, email, and AI services to create a complete invoice management pipeline—from ingestion and extraction to validation, storage, and team notification. Each workflow is customizable and importable into n8n.

This pack is for finance teams, accounts payable staff, and small business owners who handle a high volume of invoices and need to reduce manual data entry. It suits teams already using Notion, Slack, Google Sheets, or email for invoice management and want to automate extraction, validation, and notification workflows.
