Billfinterface is a software architecture pattern designed to provide a standardized mechanism for the integration of billing and payment processing systems with external applications and services. The concept emerged in the early 2010s as enterprises required greater flexibility to expose billing capabilities to partner ecosystems, mobile platforms, and cloud-based services without duplicating low‑level payment logic.

Key features of a Billfinterface implementation typically include a RESTful or gRPC API layer, an event‑driven
Adoption of Billfinterface has become common in fintech startups that need rapid scalability, in e‑commerce platforms
The architecture promotes modularity, ensuring that changes to a payment processor or tax calculation policy can
