I find it helps to divide the transaction into the sending side and the receiving side.
The origination side is where you accept the sender’s business and arrange the transfer. You need a lawful basis to offer that service in the relevant market, whether through your own authorization, an appropriately structured relationship with a licensed provider, or an applicable exemption.
The payment processor helps collect the sender’s money. That could involve a card payment, a bank debit or another supported payment method. Being able to collect a card payment does not, by itself, mean the processor provides everything needed for the international transfer.
The payout partner handles delivery in the beneficiary’s market. Depending on the corridor and payment method, that could be a bank, mobile-money operator, remittance company or another appropriately authorized provider. An aggregator may connect you to several such partners.
For example, collecting a sender’s payment in the United States and delivering money into a beneficiary’s mobile wallet overseas are different jobs. Your U.S. processing arrangement does not automatically establish the overseas payout arrangement.
One provider can perform several roles, but I would still map them separately. Ask who collects, who converts, who settles and who delivers to the beneficiary. Confirm the actual countries and payout methods supported, along with the permissions and contractual responsibilities for each part. That gives you a much clearer picture of what you have bought and what remains missing.
