Implementing the right technical solution to enable a bitcoin payment gateway comes with challenges depending on what the current solution the business is using. Most of the ecommerce today offers a bitcoin or lighting integration for easy setup, both custodial or noncustodial.

For the compliance side, it's easy. Bitcoin, with lightning, is just as extra digital cash flow, so in the books you treat it as such. Who wouldn't want and extra cashflow?
