Automated Stripe Payment & Invoicing

2 days 4.8/5.0

Stripe payment and invoicing automation via Zapier — detects existing customers, generates invoices automatically, and integrates with Keygen for software license data. Zero manual billing steps.

!

The Problem

The client was manually creating Stripe invoices for every new customer and software license purchase. Existing customers were being duplicated, payments were delayed, and the team spent hours each week on repetitive billing tasks that should have been automated.

The Solution

Built a Zapier automation that detects whether a customer already exists in Stripe before processing. If found, it generates an invoice directly. If not, it creates the customer first, then processes payment. Integrated with Keygen to pull software license details automatically — ensuring every transaction is accurate without manual data entry.

How It Works

1

New purchase triggers the Zapier workflow via webhook

2

System checks Stripe for existing customer by email

3

If customer exists → generate invoice immediately

4

If new customer → create Stripe customer record first

5

Pull license details from Keygen API automatically

6

Invoice sent to customer — zero manual steps
