Most of the mobile_money payouts are instant, 90% of most of the time. The other lag is based on the speed of the service provider/operator enabling the payout.
However, our system releases them instantly to be processed and paid out.
For some countries like South Africa. Our partner could take 2-4 days for the transaction to complete or reflect as complete in our system. We in return update ZAR payouts after 4-5 working days but the customers receive their funds within 24 hours from the time the transaction was initiated.
