Enter account number, amount, PIN, Confirm
Read the recipient name before tapping send. It must read GWASCO or a close variant. If it shows any other name, cancel; you are about to pay a scam paybill.

Keep the M-PESA SMS
The 10-character transaction code (e.g. TFB2NXY7P9) is your receipt. Keep it for at least 90 days in case the payment does not reflect or you need to escalate.
Bank app alternatives
Most major bank apps include a Pay Utility Bill flow that handles GWASCO. The flow is usually faster than M-PESA paybill (bank-to-bank settlement) and avoids the M-PESA paybill tariff.
