Maple Billing is an end-to-end billing workflow product that combines the functionalities of Stripe, Baremetrics, and Docusign, offering automation and tools for engineering, product, sales, and revenue teams with minimal coding. The co-founder, Aswinkumar Rajendiran, emphasizes the importance of notifications in their business operations, utilizing webhooks to keep customers informed about various events, such as new subscriptions or changes in subscription plans. Initially, Maple Billing considered building their own webhook implementation but decided to integrate Convoy, an open-source webhook gateway, after migrating their datastore to PostgreSQL, which provided better support and scalability compared to MongoDB. The integration with Convoy has improved their developer experience, allowing them to recommend it to their customers for seamless receipt of webhooks, enhancing overall operational efficiency.
