What free actually gets you, and what it costs
You get a booking link that respects your calendar, which is the single most useful thing on the list. Calendly’s free tier does this properly rather than as a trial.
You do not get payment at booking, a contract, packages, client records or anywhere for the engagement to live. Each of those becomes a manual step.
What the manual steps cost is enquiries. A client who has decided at 10pm and has to wait for an invoice tomorrow is a client who sometimes does not complete. In a consumer niche that share is not small.
So the honest framing is that free costs you conversion rather than money, and whether that trade is right depends entirely on how many enquiries you currently have.

A free stack that actually works
It is worth spelling out, because it is the right answer for a genuinely common situation and most advice skips past it toward a subscription.
Booking: Calendly free tier. Real availability, real confirmations, indefinitely.
Payment: a payment link from your processor. Roughly 3% and no monthly fee.
Contract: a one-page agreement covering scope, cancellation, rescheduling and payment terms, signed by reply. Twenty minutes to write once.
Sessions: Zoom free is capped at forty minutes, which does not work for coaching, so this is the one line where a small cost is unavoidable at $14.99.
That takes a paying client this week. The cost is the joins between the four, and those joins are exactly what a subscription removes.
The verdict
If you have no clients and no revenue, use Calendly’s free tier, a payment link and a one-page agreement. That combination will take your first paying client and it costs nothing.
The point to watch for is when the manual steps start costing more than a subscription would, which for most coaches arrives around the third or fourth client rather than at any particular revenue figure. Until then, free is the correct answer and the money is better spent on outreach.
