At this point, it's a question of time to build in additional systems. Stripe Connect let me (the solo engineer) build a marketplace quickly. However, it doesn't have great international support.
We are looking at other options, such as Payoneer. The main priority right now is on growing the client side of the market. However, after that, we will likely return to the contractor side to work on some projects such as expanding payment options.
Only issue for me is that you only support stripe for payments and is not available in my country, Uruguay.
Why is that? Why not leave the payment chanel free? Or use paypal or something else?
