Ask HN: How could we handle payout to sub-merchants in unsupported country

I've read https://openchannel.io/blog/marketplace-payments-paypal-stripe/

Basically, out of those options we have found Stripe to be the best fit for long run.

Now we also have sub-merchants in countries that are not supported by Stripe as of now, we cannot onboard sub-merchants to Stripe Connect.

We were thinking of paying out to from Stripe to Transferwise (or similiar), and from Transferwise to sub-merchants.

But this would create a problem, we would have to create some kind of accounting system to make sure everything went smooth.

Have any of you tackled this problem in your company?

Thanks
