11 of 17 tracked booking & scheduling tools publish an entry plan under $20/mo, including 10 with a genuine $0 free tier. The cheapest paid entry is Bookeo at $14.95/mo. Watch the billing model: a per-seat sticker under $20 is per user, so it multiplies by the number of staff who need a calendar.

Frequently asked
- Is there booking software under $20 a month?
- Yes — 11 vendors list an entry plan below $20/mo, the cheapest paid being Bookeo at $14.95/mo, and 10 are free. For per-seat tools that figure is per user, so confirm how many staff calendars you need.
- Are the cheap plans full-featured?
- Entry tiers cap something — staff seats, calendars, booking pages, or monthly appointments — and gate SMS reminders, removed branding and integrations to higher tiers. They suit a solo professional or a small calendar.
- Does a low sticker mean low total cost?
- Not for per-seat pricing. A low per-user rate multiplies by headcount, so a three-person team on a $10/user plan pays $30/mo. Flat plans hold their price as the team grows — compare at your real staff count.
