Client Billing Collection & Invoice Generation with Gmail + QuickBooks

This workflow streamlines the invoicing process for freelancers and small businesses by automating the collection of missing client billing information. It starts with a manual trigger where you input the client's email, invoice amount, description, and product. A customized email is sent via Gmail requesting billing details, directing the client to a hosted form. Once submitted, the workflow checks QuickBooks for the client: creating a new record if needed or using an existing one. It then generates a professional invoice with the provided details and product, and automatically emails it to the client using QuickBooks' native system.

Key benefits include eliminating manual data entry, reducing email back-and-forth, and minimizing errors in billing. It saves hours per invoice by integrating Gmail for communication and QuickBooks for accounting, ensuring compliance and professionalism without app-switching.

Ideal use cases: Freelancers invoicing new clients, small businesses onboarding customers, sales teams handling service requests, or ops automating follow-ups. Perfect for anyone tired of chasing billing info manually.

Setup is straightforward: Connect Gmail and QuickBooks OAuth2 credentials, customize the product dropdown in the trigger node, and ensure product names match QuickBooks exactly.
