While the payment facilitator model has grown in popularity as a way to board merchants quickly and with minimal friction, the marketplace model can be more suitable to aggregators wanting to globalize their seller organization without being incorporated in all the countries of interest or have an acquirer for each country.  If you manage your sellers refunds and chargebacks on their behalf or are willing to take on these responsibilities, as well as being considered as a money transmitter, RPY can help.  We will assist your business in considering all the aspects of being a marketplace model from developing the proper policies and procedures to developing an operations workflow that complies with all the regulations.
