Can the system send my customers a reminder before their trip so my staff are not chasing everyone by hand?

Yes, in most cases you can set this up so reminders go out on their own. The system already knows the departure date and any balance due date on a booking, so you can decide how far ahead a message should go and it will be sent without anyone in your office having to remember. Most agencies use one reminder to confirm the travel details and another to ask for money still owed on a package.

You normally control the wording, and the message carries your own company name and logo rather than anyone else's, so it reads as coming from your agency. You can usually turn individual reminders on or off, and switch them off for certain kinds of bookings if they do not suit. It is worth keeping the number of automatic messages small, because customers who have just booked do not want several emails in a row.

Be aware of a few honest limits. Email reminders are the normal starting point and are generally included, while text messages and chat messages depend on your plan and usually need an account with a messaging provider who will charge you separately for what you send. Emails only arrive reliably if your sending domain is set up correctly, so that is worth sorting out before you depend on it. Reminders also only reflect what is recorded on the booking, so a change made directly with a supplier will not be picked up unless the booking is updated.

The next step is to ask which reminders your plan includes, then send a test to an address of your own and read it as a customer would before you switch it on for everyone.
