THE SHORT ANSWER
If you are a freelancer, consultant, or solo coach with simple needs → TidyCal ($29 once)
If you are a service business taking payments at booking → Acuity
If you are a sales team or B2B company needing CRM sync → Calendly
Not sure which you are? The full breakdown is below.
One costs $29 once, one costs $10/month per seat, one costs $16–49/month flat. The right answer is decided by your business type, not the feature list.

TidyCal — for solo professionals
If your scheduling needs are simple and stable, TidyCal wins. It costs $29 one-time for lifetime access — no monthly fee, ever. Unlimited bookings, unlimited event types, Google/Apple/Outlook calendar sync, group bookings, Stripe and PayPal payments, Zoom/Meet/Teams links. What it does not have: routing forms, meeting polls, round-robin scheduling, Salesforce/Gong native sync, HIPAA compliance. If your needs are stable and simple, this gap will never matter.
Acuity — for service businesses
If you take payments at the time of booking and run a service business, Acuity is the answer. Acuity Growing costs $27/month flat per account — not per seat. Emerging at $16/month covers solo service providers. Growing at $27/month adds automation and multiple calendars. Powerhouse at $49/month adds advanced reporting and API access. A team of six on Growing pays $27/month total. Six Calendly Standard seats cost $60/month. For service businesses with staff, Acuity's per-account pricing wins on cost. No free plan. HIPAA compliance on all paid plans — essential for healthcare, therapy, and wellness businesses.
Calendly — for sales teams
If you are a B2B company with a sales team needing routing and CRM sync, Calendly is the answer. Calendly Standard costs $10/seat/month for unlimited event types, payments, workflows, and most integrations. The free plan allows one event type and one calendar integration. A freelance consultant booking three call types — discovery, strategy, follow-up — cannot use the free plan. This is a meaningful limitation the free plan marketing undersells. Teams at $16/seat/month adds round-robin, collective meetings, admin management, and SSO. A five-person sales team on Standard runs $50/month; on Teams, $80/month.
When it actually pays off
| User type | TidyCal | Calendly Standard | Acuity Growing |
|---|---|---|---|
| Solo, simple needs | $29 total | $360/yr ($1,080 over 3yr) | $324/yr ($972 over 3yr) |
| 3-person service team | $29 total | $1,080/yr ($3,240/3yr) | $324/yr ($972 over 3yr) |
| 5-person sales team (CRM needed) | no CRM | $1,800/yr — routing/CRM | lacks CRM depth |
TidyCal's lifetime economics are difficult to argue with for the right user. Three years of Calendly Standard for one seat costs $1,080. TidyCal costs $29 once. That $1,051 gap over three years needs to buy you something real. For a solo consultant: it does not. For a service business taking payments: Acuity's flat team pricing beats both. For a B2B sales team: Calendly's routing and CRM sync justify the per-seat cost.
What nobody else mentions
Calendly's free plan is more limited than marketed. One event type is genuinely restrictive for most professionals running multiple call formats. Most people need Standard on day one.
Acuity's per-account pricing is its biggest advantage. Most comparisons show per-seat pricing as the norm. Acuity charges per account. A six-person therapy practice on Powerhouse pays $49/month for the whole team. Six Calendly Teams seats cost $96/month.
TidyCal's update cadence is slower. AppSumo lifetime deals are built to a specific product version. If you need new integrations as your stack grows over several years, this is a real consideration.
Acuity is now owned by Squarespace. If you are building on Squarespace, Acuity integrates natively and the combined cost makes sense.
Cal.com is the open-source alternative. Free tier, self-hostable, GitHub-backed. Worth knowing if none of the three above fit your situation.
