Can the software remind me when a customer still owes me a balance so I don't forget to chase it?

Yes, in most setups the travel agency software can keep track of what a customer still owes and remind you before that balance is due. When you take a deposit, you record what was received against the booking and the system holds the remaining amount along with the date you want it collected by. The booking then shows as part paid rather than settled, so you can pull up a list of everything with money outstanding instead of going through your own notes one file at a time.

The reminders themselves can usually go to you or to the member of staff who owns the booking, and in many cases a polite reminder can go to the customer as well. How many days before the due date they go out, and whether the customer gets one automatically or you choose to send it, are things we set up with you rather than fixed rules. Whether automated customer emails are part of what you have depends on your plan, so it is worth asking before you rely on it.

The one honest limit is the due date. For some bookings the supplier payment deadline comes through with the booking itself, but for others, especially trips you arranged offline or under your own direct contracts, you enter the date yourself. The software can only chase what it has been told, so a reminder is a help to your own memory, not a promise that a supplier will keep holding the booking if payment is late.

When you are getting set up, decide who in your team should receive these reminders and how far ahead you want them, and make a habit of entering the balance due date at the moment you take the deposit.
