The right restaurant, a private room, dietary needs collected. Comtev sources, negotiates and holds it, and nothing books until you approve.
Comtev reaches the venues, gets real availability and a rate, and holds the room while you confirm.
It asks each guest for what they need and chases the ones who don't reply.
See the price first; a send-back goes straight back out to renegotiate.
One brief in, real quotes back, one live budget you can take to finance.
