The Problem We Were Actually Solving
On the surface, the issue seemed simple: we just needed to find a way to process payments for users in Nigeria. But the reality was more complicated. Every payment processor I approached told me the same thing: their systems were optimized for high-volume, low-latency transactions in developed markets, and they didn't have the resources to support the nuances of emerging markets. It wasn't that they were unwilling to help - it's just that their systems were fundamentally designed with the needs of Western customers in mind.
What We Tried First (And Why It Failed)
Our first approach was to try to use existing payment gateways like Payhip and Gumroad. These services promised to handle international transactions seamlessly, but they were ultimately just wrappers around the existing payment processors. When they encountered a Nigerian customer, they would fail to process the payment, and the customer would be left with an error message that said "Payment failed" with no clear explanation of why.
We also tried to use a Nigerian bank's payment gateway, but it turned out to be a mess. The bank's system was designed to support domestic transactions, and it didn't have the necessary APIs or infrastructure to handle international payments. We spent weeks trying to integrate with their system, only to realize that it was just not designed for our use case.
The Architecture Decision
After months of experimentation, we finally decided to go with a custom solution. We built our own payment processor using the Nigerian Interbank Settlement System (NIBSS) API, which allowed us to route payments directly to the bank accounts of our users. This approach required a significant investment of time and resources, but it ultimately paid off. We were able to process payments for our Nigerian customers with a high degree of reliability and low latency.
What The Numbers Said After
The results were dramatic. After we switched to our custom payment processor, our transaction success rate for Nigerian customers jumped from 20% to over 95%. This wasn't just a matter of getting payments to go through - it was also a matter of customer satisfaction. When customers can make payments easily, they're more likely to do business with you in the first place. We saw a significant increase in sales and user acquisition after we made this change.
What I Would Do Differently
In retrospect, I would have started with a more nuanced understanding of the payment processing landscape in Nigeria. I would have spent more time researching the different payment processors and gateways available, and I would have spoken with more customers to understand their pain points. I would have also started building our custom payment processor earlier, rather than trying to integrate with existing systems that weren't designed for our use case.
Looking back, I'm struck by the limitations of traditional payment platforms in emerging markets. They're designed with the needs of developed markets in mind, and they often fail to account for the complexities of emerging markets. As engineers, we need to be willing to think outside the box and build solutions that are tailored to the specific needs of our customers. In this case, that meant building a custom payment processor from scratch - and it was worth it.
