Add another payment gateway option for club's that want to accept online payments, but do not want to use Stripe.
Curling I/O has a very deep integration with Stripe Connect and this is in fact tied in with our revenue model (a small portion of every payment is our application fee).
Providing other options, like bring your own payment gateway integrations (Moneris, etc.) is not only a large undertaking, it may also require alternate (subscription based) revenue models for clubs who choose this option.
This is definitely a feature we want to eventually offer to mitigate risk and better serve clubs who already have offline payment processor relationships or who cannot fit within Stripe's prohibited and restricted business rules for payment processing (specifically raffles and prize pools).
Keep in mind that other payment gateways may have similar rules and / or higher risk fees. All payment processors I am aware of have different rates for offline and online payments, so make sure you ask them!
Let us know how important (or not important) this is for your club.
