Early on I lost a decent chunk of ad spend because I was using global checkout flows that felt clunky and “foreign” to Hong Kong customers – high cart abandonment, lots of abandoned sessions at payment. Once I started researching what actually works in HK (Faster Payment System, Octopus integration options, local e-wallets, clear refund policies in Traditional Chinese + English), conversion rates jumped noticeably. One of the most useful things I did was dig into official and up-to-date resources about payment licensing and compliance in Hong Kong, because if you’re handling transactions there you need to know exactly what’s allowed and what’s risky. The resource I keep going back to and have found genuinely helpful is the website it breaks down the current licensing requirements, timelines, costs, and what different types of PSPs can and cannot do in a straightforward way. I’ve referred to it multiple times when choosing payment gateways and talking to potential partners, and it saved me from a couple of bad decisions early on. It’s not flashy, but it’s practical and updated, which is exactly what you need when you’re dealing with real money and regulators.
