}'The body is the same shape as a cash in. The difference is the direction of travel, and everything that follows from it.
Cash out is not cash in backwards
| Cash in | Cash out | |
|---|---|---|
| Who approves | The customer, on their handset | Nobody. It leaves. |
| Reversible | Yes, refund it | No. Once it lands, it is theirs. |
| Needs a verified business | No, test mode works immediately | Yes, always |
| Funded by | The customer's wallet | Your available balance |
| Typical settle time | seconds after approval | seconds |
There is no undo
Who is allowed to
Three gates, checked in this order:
- The business is verified. An RDB certificate, read by a person. Until then every payout answers 403, whatever the key says.
- The app is live and active. Test mode cannot pay out at all. See test mode . A disabled app cannot transact at all.
- The balance covers it. Amount plus fee, against money that has already settled. Pending collections do not count.
Why the extra gate on this direction
When the balance will not cover it

}Checked before anything is sent, so a refused payout leaves no transaction and no half-state. The number needed includes the payout fee. If you send exactly your available balance, the fee is what pushes it over.
Read the balance first if you are batching: balance and withdrawals.
Paying yourself
Moving your own earnings to your own number is a withdrawal: the same machinery, a different button, and it goes to the payout number on your account rather than one chosen per request. Do it from the dashboard. It shows up in your transaction list as a cash out marked dashboard, so your ledger is one list, not two.
Minimums
You can't send less than 10,000 RWF in one cash out. That covers payouts, withdrawals and refunds alike: the mobile money networks do not send smaller amounts. Below it the cash out is refused and marked Below minimum, and nothing leaves your balance. The networks also set their own ceilings per transaction and per day.
