Frequent user of SystemSpecs payment system here and I must say the Remita infrastructure is solid honestly. Integration was smooth when our school started using it for online fee payments and parents have been able to process transactions without major issues. My only gripe is when we had a technical glitch mid-session, took them almost 3 hours to get back to us even though we flagged it as urgent. For a payment provider handling this kind of traffic, response time like that can cost you small small lost transactions na.
