The verdict
For a small B2B team, pick Calendly. It works on day one, prospects already know it, it has a free plan, and it connects to nearly everything.
Pick Chili Piper when inbound demo requests are a real revenue source, several reps share the leads and the CRM decides who owns what. Then the routing rules and the handoff from SDR to AE earn their cost.
If your booking need is a link, Chili Piper is overkill. If leads sit for hours while someone assigns them, test Chili Piper with your own form tool before you sign.
