Stripe and PayPal require a US or EU bank account in order to do withdrawals directly to your account. A verified Stripe account will give you payouts 1-2 times per week. PayPal is dependent on your withdrawal requests.
PayPal only supports XOOM locally - no direct bank support.
Some of the local banks offer payment gateways but I've never done setup of those. I believe they're only card processing on your website. Check with Sagicor for more details as I recall seeing something in their banking hall about supporting online payment. The other banks probably do as well, so if you bank with BNS/NCB then speak with a rep directly for more details. If you find anything then please share.
Knowing the solution doesn't mean knowing the method. Yet answering correctly and regurgitation are considered "learning" and "knowledge".
