Coupay - Smart Invoicing
& Payment Platform
Streamlining Payments for SMEs & Freelancers with Open Banking
Our client, Coupay, is a growing fintech startup that set out to change how small businesses, freelancers, and self-employed professionals handle payments. Their goal was to make invoicing simpler and speed up bank transfers. By using Open Banking technology, they built a secure, easy-to-use platform.
Coupay wanted to solve the common problems of high costs and inefficiencies in traditional payment methods, giving users a better way to manage their finances with confidence and convenience.
What Was the Challenge?
Before Coupay, small businesses, freelancers, and self-employed professionals faced several challenges with payments:

High Transaction Fees: Traditional payment solutions charged steep fees, cutting into already tight profit margins.
Limited Access to Simple Solutions: Existing tools were often complicated, costly, or lacked features tailored to SMEs and freelancers.
Cash Flow Struggles: Payment delays and disorganized invoicing made it hard for users to maintain steady cash flow, affecting their financial stability.
