Once a booking has been accepted a renter has 2 weeks to make a payment before it expires. When a booking has expired it cannot be reactivated.
If the renter is still interested to make a payment after the booking has expired, they will have to send the booking request again. 

We always encourage renters to make a payment as soon as possible to secure their booking.

For more information regarding the payment schedule, please refer to the following article:
How do the payments work?
