Possefy Pay is a multi-provider payment orchestration system connecting a front-end layer (OOW) through a centralized middle layer to five distinct payment processors and lending partners. Data flows bidirectionally from the OOW front end through Mars back end to warehouse and invoice systems, while payment requests route through POSSEFY PAY to 2C2P credit cards, SG Capital loans, Shopee e-pay, UFund loans, and Krungsri Finance options. This architecture decouples payment provider integrations from core business logic, enabling flexible payment method selection and reducing vendor lock-in risk.

The system addresses fee and refund issues in legacy Paysolution by introducing a dedicated middle layer that standardizes payment processing across multiple regional and product-specific partners.
