For NZ based, if you want multi currency support DPS is really the only way to go. Quite expensive at the onset but other ones like Paystation are designed more for local trading. Last I checked Paystation had some limitations that made it unfeasible to work in the US. Paypal (the non hosted one) is quite easy to setup and you don't need a merchant account for it. Otherwise for DPS/Paystation you'll also need a Merchant account through a bank.

I found early on, the best thing to do was to talk to your business banker about options for merchant accounts, they often deal with DPS or Paystation and can explain what the process you need to do is.

Hi Willr,

Sorry to bother you again, I'm new to this. I'm just wondering how do I implement payment gateways to the Ecommerce site in Silverstripe? Do you have any good tutorials that I can follow?

Thank you very muchm Willr. By the way I'm thinking of using DPS as the gateway.

Thanks,
Sam:)
