What it does

This template automates internal equipment and supply purchase requests for operations, HR, and IT teams. Requests are submitted via a built-in n8n form, automatically approved for small amounts, and routed to the manager via Slack for larger ones — with full logging to Google Sheets throughout. Who this is for Operations, HR, and IT teams at Japanese companies who want to eliminate manual back-and-forth for internal purchase requests. No external form tools required. What's included A single workflow that handles the full purchase request lifecycle: 1. Purchase Request Form — Applicants submit item details via n8n's built-in form. No external tools needed. 2. Manager Lookup — The approving manager's Slack ID is automatically retrieved from a Google Sheets mapping table. No Slack IDs in the form. 3. Request Logging — Every request is appended to Google Sheets with a unique request ID and status tracking. 4. Amount Threshold Check — Requests at or below the threshold (default: ¥10,000) are auto-approved. Requests above are routed to the manager. 5. Auto-Approval Route — Status is updated, the purchasing team is notified via Slack, and the applicant receives a confirmation email. 6. Manager Approval via Slack — The manager receives a Slack DM with a custom form: approve/reject selection and a free-text comment field. 7. Approval Route — Status is updated with approver name, purchasing team is notified via Slack, and the applicant receives a confirmation email. 8. Rejection Route — Status is updated with the rejection comment, and the applicant receives a rejection email including the manager's comment.
