The verdict
For a small B2B team, pick Cal.com. It has a free plan, the routing forms cover most simple qualification, and you can embed it and shape it to look like part of your product.
Pick Chili Piper when inbound demand is a real revenue source, several reps share the leads and your CRM is the system of record. The routing is the point, and the faster booking follows from it.
If one booking link would do, Chili Piper is overkill. If you are comparing them because leads wait for hours before anyone assigns them, test Chili Piper in a demo with your own form tool first.
