You can select to pay using M-Pesa, you will be charged at the time of creating/scheduling your booking based on the estimate our system provides. If the booking ends up being shorter your account will be credited with SweepCred which you may use against a future booking. If the booking ends up being longer you will be invoiced for the additional time. You also have the option to manage your account using SweepCred - top up your account with SweepCred - schedule your bookings at any point and your SweepCred account will be charged.
