One operator screen for orders, weighbridge tokens, tanks and trucks. The website is the only place data is entered — n8n keeps Google Sheets as the operational record.
Every form posts to your n8n webhook, which validates the transaction before any sheet is touched.
Order balance, truck capacity, tank stock, product match and WB token uniqueness are all checked first.
Dashboard, orders, tanks and trucks are read live — no hardcoded or sample records anywhere.
