PayXpress is a Value-Added Services (VAS) platform under Xpress Payment Solutions. The platform allows users to:
Purchase airtime, data, and utility bills.
Fund their wallets via cards, bank transfers, or agents.
Access services through mobile apps, the web, and POS.
Before this redesign, the user experience was fragmented, with inconsistent layouts, limited user guidance, and a high rate of incomplete transactions—especially on mobile.
Users often find the PayXpress experience confusing and unintuitive, leading to a high drop-off rate during transactions, low repeat usage, and a heavy reliance on support teams for help.
Our PayXpress platform will let users fund their wallets, pay bills, and manage transactions on both web and mobile, which will affect everyday customers and agents by providing a faster, more intuitive, and secure payment experience. We will measure effectiveness by tracking task success rates, user retention, reduction in support tickets, and Net Promoter Score (NPS).
