"content": "## Automate inventory reordering and vendor bill approval with Odoo, Gmail, and Slack\n\n### How it works\n\nThis workflow automates two purchasing operations: a scheduled daily inventory reorder check and an email-driven vendor bill approval process. It checks Odoo for low-stock products, creates draft purchase orders, emails vendors, and notifies procurement in Slack. Separately, it watches Gmail for vendor bills, extracts bill details, creates draft bills in Odoo, requests finance approval in Slack, and either posts the bill or asks the submitter for changes.\n\n### Setup steps\n\n- Configure Odoo credentials and verify access to products, vendors, purchase orders, vendor partners, and vendor bills.\n- Configure Gmail credentials for both the vendor bill trigger mailbox and outbound notification emails.\n- Configure Slack credentials and set the procurement, finance approval, and automation error channels or users.\n- Set the daily schedule trigger to the desired timezone and confirm the reorder threshold logic in the low-stock Odoo query.\n- Define the Gmail trigger filters for vendor bill emails and verify the extraction fields for vendor name, bill amount, reference, and submitter email.\n\n### Customization\n\nAdjust reorder thresholds, preferred vendor selection rules, Slack approval recipients, email templates, and Odoo draft/confirmation fields to match internal purchasing and finance policies."
