I created an automated payment reminder and collection workflow that helps businesses stay on top of overdue invoices with zero manual effort. 
The system automatically generates a Stripe payment link, then shortens it for easy sharing.
After 3 days, customers get a friendly email reminder.
After 7 days, they receive an SMS reminder(Twilio).
After 14 days, a Slack message alerts the collection team to follow up.
And here’s the best part — once a payment is made, the Stripe signature is verified for authenticity to ensure every transaction is genuine before updating records. 
Automation + security = peace of mind.
