Stripe is awesome at making payments easy.  You can integrate with their API in a matter of minutes and start collecting money instantly.  The best part is that you don’t have any monthly fees to worry about.  You only pay when you get paid.  One downside to Stripe is that it is hard to send customized notifications to your customer about their payment.  Unless you’re the developer behind the Stripe integration, your options are limited. With WebMerge integration you can automatically send payment receipts, thank you letters, and more by using Stripe payment information.  Simply setup templates in WebMerge and then you can integrate Stripe using Zapier to create your documents when you receive a new customer or a new payment.
