InvoiceBot

Overview

InvoiceBot automates the entire invoicing workflow for freelancers, agencies, and B2B service businesses by instantly generating and sending professional Stripe invoices the moment a deal closes in HubSpot. This AI-powered invoice automation agent eliminates manual data entry, reduces billing delays, and ensures every closed deal converts to a payment-ready invoice within seconds—no more time wasted on administrative tasks between deal closure and client billing.

How It Works

1. Trigger on Deal Close (HubSpot) — Detects when a deal reaches "Closed Won" stage and retrieves deal details including amount, line items, client company, and primary contact information
2. Fetch Contact Details (HubSpot) — Retrieves the primary contact's name and email address to ensure accurate invoicing
3. Search Stripe Customers (Stripe) — Queries your Stripe account to check if a customer profile already exists for this client, preventing duplicate records
4. Create or Reuse Customer (Stripe) — If the customer doesn't exist, automatically creates a new Stripe customer profile with the contact's name and email
5. Add Line Items (Stripe) — Converts each deal line item into professional invoice line items with descriptions and amounts
6. Generate Invoice (Stripe) — Creates the actual Stripe invoice with customizable payment terms (default 14-day net) in draft status
7. Compose Professional Email (Claude Sonnet) — Uses advanced AI reasoning to draft a personalized invoice cover email that references the project details and payment terms
8. Create Email Draft (Gmail) — Saves the invoice email as a Gmail draft with the Stripe invoice link embedded, ready for human review and sending
9. Log Activity (HubSpot) — Records the invoice creation as a deal activity for complete audit trail and CRM integration
