Can my website handle a booking for a large group on one flight or do I have to split it up?

Mostly no, not as a single flight booking, and the reason sits with the airlines rather than with us. Most flight content, whether it comes through a global distribution system or straight from an airline, limits the number of passengers allowed in one search and one booking. Once your group goes past that limit, it has to be split into several smaller bookings, or handled as a group request with the airline's group desk, where the fare and the rules are different.

What your portal can do is make the splitting manageable. Your staff can run the search, then create the bookings one after another under the same customer record, so the group stays together in your reports and your paperwork even though the airline sees separate tickets. Whether everyone ends up on the same flight depends on how many seats are still for sale at that fare when you book, and that can change while you work.

The limits are worth knowing honestly. Split bookings can sit on different fares, and if the airline changes the flight it may not treat them as one party. Real group fares, with their own deposit and name change rules, usually still need a conversation with the airline or a consolidator, and the booking is then loaded into the system rather than searched in it.

Tell us which flight sources you expect to use most for group travel, and we can confirm the passenger limit each one enforces and how your staff should set groups up around it.
