The basics

What each one actually is

What is Acuity Scheduling?

Acuity Scheduling is a long-standing scheduling tool with deep roots in the wellness and services industries. Acquired by Squarespace in 2019, it grew up serving solo practitioners — therapists, hairstylists, trainers, photographers — and the product still reflects that lineage.

Acuity offers granular intake forms, one-off appointments and recurring services, basic package and gift certificate functionality, and direct payment integration with Stripe, Square, and PayPal. Group classes with a class roster view are included as well.

The product is mature, dependable, and broad. Where it shows its age is in how the modern features feel layered on rather than designed in: packages exist but read as a bolt-on, the client view is partial, and the $20/month entry price reflects an older era of SaaS pricing. There is no free plan beyond a 7-day trial.

What is Calso?

Calso is a session lifecycle platform built for coaches, consultants, and wellness practitioners. Where a traditional scheduler ends at the calendar invite, Calso treats the booking as the start of a relationship.

Clients have profiles. Sessions accumulate into histories. Packages issue and consume credits automatically. Payments flow directly to the practitioner via Stripe Connect. Group events, digital products, intake forms, and configurable payment plans all sit alongside one-to-one bookings — not as upsells, but as first-class parts of the product.

Calso has a Starter plan that's free with no time limit, and paid plans from $9/month. The product is built around one premise: most practitioners aren't trying to book more meetings — they're trying to run a practice, and the platform should understand that.

The core difference

Same booking link. Different product.

Acuity is a solid scheduling tool with strong roots in wellness — intake forms, packages as a bolt-on, client management basics. Calso is built from the premise that packages and client lifecycle aren't add-ons; they're the core product. The result is a platform where session history, package tracking, and payments are first-class — not features stapled onto a calendar.

Pricing, in plain terms

What you actually pay

Acuity starts at $20/month for Starter (one calendar, basic features), rising to $34/month for Standard and $61/month for Premium on monthly billing as of August 2026 — the higher tiers unlocking team scheduling and multiple locations. There is no free tier; you get a 7-day trial.

Calso's free Starter plan is genuinely free with no time limit: 3 event types, single and group sessions (up to 10 attendees), Stripe payments, and client records with no client cap. Packages, installment payment plans, and the client portal arrive at $9/month for Practice — territory where Acuity asks $34 for Standard before packages unlock.

For a solo practitioner who's been on Acuity Starter for years, switching to Calso typically means more functionality for less than half the cost — and a real free tier to test the product before committing.

Where Calso wins

The practice-shaped wins

01
Built for packages

Packages are the foundation

In Acuity, packages work but feel bolted on — the core product is still 'book a time.' In Calso, the platform is designed around selling sessions in packages from the ground up.

02
Free plan

A free plan, no trial clock

Acuity has no free tier — you're on a trial countdown from day one. Calso's Starter plan is free with no time limit.

03
Half the price

More for less

Calso's paid plans start at $9/month vs Acuity's $20/month, with more practice-specific functionality at every tier.

Honest fit

Where Acuity Scheduling might be the better fit

No tool wins on every dimension. These are the cases where we'd point you toward them, not us.

  • You rely heavily on mature intake forms and client questionnaires — Acuity's form builder is deeply integrated across booking flows.

  • You need Square as your payment processor — Calso supports Stripe and PayPal, but not Square.

Who Calso is built for

For practices that have outgrown a basic scheduler

Practitioners who have outgrown a basic scheduler and want a platform that understands packages, tracks clients across sessions, and connects payments directly to them — without paying enterprise prices to get there.
How to choose

Acuity Scheduling or Calso? Pick the right one

If you've built years of muscle memory around Acuity's intake form builder and your workflow depends on the specific way that form data routes through your booking and email flows, the switching cost may not be worth it. Acuity's forms are mature and deeply embedded. Same if you specifically need Square as your payment processor (Calso supports Stripe and PayPal, but not Square).

For everyone else: Calso is meaningfully cheaper at the entry tier, has a genuine free plan, and treats packages and client lifecycle as the core product instead of an add-on.

If you opened Acuity today to set up a multi-session package and found the experience a little clunky, that's because it was built to schedule appointments first and everything else second. Calso is the inverse.
