Hi Herliesha, it really depends on the supplier and how far out the booking is made. Some suppliers offer payment plans, or you (as the travel agent) could set up a payment plan depending how far out the booking is made. For instance, for a trip booked 6 months out, the supplier may only care that a deposit and final payment is made, but the travel agent can determine a monthly payment plan with their client and manually add payments each month to the reservation. The client management tool we offer, myTravelCRM, can help agents manage their clients' payments and is even able to send payment reminders. Please feel free to reach out to our team at 1-888-611-1220 if you have any other questions!
