Send AI sales proposals and Stripe payment links after Calendly calls

Meeting → Proposal → Payment → Follow-up Automation

Categories: Sales Automation, AI Proposals, Revenue Ops

This workflow automatically turns a booked sales call into a customized proposal, a Stripe payment link, and a follow-up email — without manual work.

It’s designed to handle everything after a sales call so momentum doesn’t die.

Booked call → proposal → payment → done.

What This Workflow Does

This automation runs the moment a sales call is booked and executes a complete post-call sales flow:

• Looks up the lead in a lightweight CRM
• Generates a tailored proposal using AI
• Creates a Google Slides proposal deck
• Creates a unique Stripe checkout link
• Sends a personalized follow-up email with proposal + payment

No manual copy-pasting. No delays. No forgotten follow-ups.

Why This Exists

Most deals are lost after the call — not during it.

This system removes:

• Manual proposal writing
• Post-call follow-up delays
• Inconsistent sales ops
• Awkward “just following up” emails

It replaces all of that with a single, reliable close flow.

Human on the outside. Fully automated underneath.

How It Works (High Level)

1. Calendly Trigger (Sales Call Booked)

• Workflow starts immediately after a meeting is scheduled
• Ensures proposals are sent while context is still fresh

2. CRM Lookup (Google Sheets)

• Finds the lead using email or company name
• Works even if the lead is unqualified or incomplete
• Simple, transparent CRM (no heavy tooling required)

3. AI Proposal Generation

• Uses structured inputs (problem, solution, scope, urgency, cost)
• Outputs a complete proposal as strict JSON
• Written in a clear, spartan, professional tone

4. Google Slides Proposal Creation

• Copies a proposal template
• Auto-fills all sections using AI output
• Generates one unique proposal per lead
• Shareable link created automatically

5. Stripe Checkout Session

• Creates a unique payment link per lead
• Attaches metadata (lead, company, package)
• No manual invoicing required

6. Follow-up Email

• Sends proposal + payment link immediately
• Personalized with name and company
• Keeps the close frictionless
