Title: Zapier + Airtable + QuickBooks Online Automation (Multi-Line Invoice Fix) Description: I need help fixing an automation between Airtable, Zapier, and QuickBooks Online. We are generating invoices from Airtable records via Zapier. The goal is to create invoices in QuickBooks with multiple line items, specifically: Line 1: Hauling / material (dynamic qty + rate) Line 2: Fuel surcharge (fixed or dynamic amount) Right now: Zapier is incorrectly sending line items as a single string (e.g. “24 1” instead of separate line items) QuickBooks throws errors like: “Amount is not equal to UnitPrice * Qty” “You must provide line items – amount” 🎯 Goal Build a working Zap that: Creates a QuickBooks invoice from Airtable Includes 2 separate line items Uses: Quantity (tons) Rate (price per ton) Fuel surcharge as a second line Displays rate correctly on invoice (not amount-only) ⚙️ Current Stack Airtable (data source) Zapier (automation) QuickBooks Online (invoicing) 📌 What I need you to do Fix or rebuild the Zap so QuickBooks receives proper line item arrays Ensure: No manual “Amount” field conflicts Rate × Quantity calculates correctly Use best-practice approach (Formatter, line items, or alternative) Test and confirm: Invoice is created successfully Both line items appear correctly Document briefly how it works so we can maintain it ⚠️ Important Notes Current issue is NOT Airtable Issue is with how Zapier sends line items to QuickBooks The UI “+ add value” approach is NOT working We need proper structured line items 💡 Bonus (nice to have) Make fuel surcharge optional (based on Airtable field) Keep system scalable for future line items
