Can I issue an invoice to my corporate clients who want to be billed at the end of the month instead of paying for every trip?

Yes, in most setups you can. Travel agency software normally lets you tag certain customers as account or credit customers, so when a booking is made for them the portal confirms it without asking for a card, records the amount against their account, and lets you send an invoice or a statement later covering everything they booked in that period. You can usually set a credit limit per client so the portal stops accepting new bookings once they reach it, which saves you chasing a company that has quietly run up more than you are comfortable carrying.

It helps to know what happens behind the scenes. Your supplier or the airline still wants paying at the time the ticket is issued or the room is confirmed, so the money for that comes from your own funds or from the credit you hold with that supplier. Billing your client monthly is an arrangement between you and them, and the software is simply keeping the record straight. That is why credit customers suit clients you already trust.

Be aware that how much of this is included depends on your plan, and that invoice layouts, tax fields and the wording you need in your country often take a little setting up before the first one goes out. Some suppliers also insist on immediate payment for certain products, so those bookings may behave differently even for an account customer.

Before you offer monthly billing, write down which clients you want on account, what limit each should have and what your invoice needs to show, then ask us to walk through how that maps onto your portal.
