Calendly vs Cal.com vs Acuity 2026: SMB Guide

Calendly vs Cal.com vs Acuity: the short version

This guide is for small and mid-sized businesses choosing a scheduling tool, from a B2B sales team booking demos to a coaching or wellness business selling sessions. The three tools overlap, but each was built for a different shape of business, and the wrong choice usually shows up as extra tools bolted on for payments, forms or routing.

Our default: Calendly for B2B teams that book external meetings, Cal.com for cost-conscious teams that want strong routing and a generous free plan, Acuity for appointment-based service businesses. The main change since spring 2026: Cal.com is no longer open source. Its public code now lives on as a separate community edition called Cal.diy.

Side-by-side comparison

Pricing

Plans and prices have moved since older comparisons were written. Acuity renamed its plans from Emerging, Growing and Powerhouse to Starter, Standard and Premium. Cal.com's Teams and Organizations plans now list at $12 and $28 per user on annual billing, lower than the $15 and $37 in older comparisons. Calendly's Standard and Teams seat prices match what older comparisons show; Enterprise starts at $15,000 a year for 50 or more seats.

What a five-person team pays

On annual billing, five seats cost about $600 a year on Calendly Standard, $960 on Calendly Teams and $720 on Cal.com Teams. Acuity is priced per account, not per user, so a practice with five staff calendars pays $27 a month on Standard, about $324 a year. That flat model is Acuity's biggest advantage for service businesses where clients book a specific practitioner.

Feature analysis

Booking experience

Calendly's booking page is familiar to most invitees, which reduces friction for prospects and clients. Cal.com's booking flow is just as clean and easier to customize, including removing its branding on Teams. Acuity's flow asks more questions by design, because intake matters when the booking is a paid appointment.

Team scheduling and routing

Calendly Teams and Cal.com Teams both support round robin, collective events and routing forms that send a lead to the right person. Calendly can route from HubSpot, Pardot or Marketo forms and send meetings to Salesforce, and Enterprise adds routing with Salesforce lookup. Cal.com Organizations adds routing by custom variables and member attributes, sub-teams and SAML SSO.

Forms, workflows and reminders

Acuity leads on intake: custom client forms on every plan, text reminders and a waitlist from Standard. Calendly Standard adds automations and reminders. Cal.com includes email and SMS notifications on the free plan, with customizable workflows on Teams.

Payments and packages

Acuity is the only one that sells packages, memberships, subscriptions and gift certificates, and it takes payments through Stripe, Square, PayPal or Venmo on every plan. If a client buys ten sessions upfront, Acuity tracks what is left. Calendly and Cal.com take per-booking payments through Stripe or PayPal, which is enough for paid consultations but not for prepaid bundles.

Open source and data ownership

This is the section that changed most. In April 2026 Cal.com announced it was going closed source, citing security. The production platform, including Teams and Enterprise, now runs on private code. The public repository became Cal.diy, an MIT-licensed community fork with Teams, Organizations, Workflows, Insights and SSO removed. Its maintainers recommend it for personal, non-production use only. If self-hosting was your reason to pick Cal.com, revisit that decision. The hosted Cal.com plans are unaffected and remain good value.

Integrations

Calendly connects to HubSpot and Mailchimp on Standard and to Salesforce, Marketo and Pardot on Teams. Cal.com lists 100+ apps and Salesforce and HubSpot sync on its free plan. Acuity integrates with online meeting tools such as Zoom, Google Meet and GoToMeeting, and with its parent company Squarespace's website tools.

Who should use which

Choose Calendly if you are a B2B company, agency or sales team booking external meetings, you want the booking flow invitees already know, and your CRM is HubSpot or Salesforce.

Choose Cal.com if you want strong team routing at a lower per-user price, or a solo founder who needs unlimited event types for free. Do not choose it for self-hosting a business system anymore.

Choose Acuity if you run a coaching, therapy, fitness, beauty, education or consulting practice that sells appointments, packages or memberships and wants payments and intake in one place, at a flat monthly price.

How to choose: five questions

If the table above has not settled it, answer these five questions in order. The first "yes" usually decides.

1. Do clients prepay for sessions, packages or memberships? If yes, choose Acuity. Neither Calendly nor Cal.com tracks prepaid bundles, and building that on top of a scheduler means another tool and manual reconciliation.
2. Do you need to route inbound leads to the right salesperson from a CRM form? If yes, compare Calendly Teams and Cal.com Teams side by side on your own routing rules. Calendly has the deeper Salesforce and marketing-automation connections; Cal.com is cheaper per user.
3. Will more than one person host meetings? If no, Cal.com's free plan or Calendly Standard is enough. A solo operator rarely needs a team plan.
4. Do you have regulated client data? Healthcare and therapy practices should check for a signed BAA. Acuity offers one on Premium, and Cal.com lists HIPAA compliance on Organizations. Confirm with the vendor before you book a single patient.
5. Is self-hosting a hard requirement? After April 2026 the only self-hosted option among the three is Cal.diy, which its maintainers recommend for personal, non-production use. For a business, that usually means choosing a hosted plan after all.

One practical test beats any comparison table: book ten real meetings through a trial account, as a client would, on a phone. Count the clicks, the questions asked and the confirmation emails. The tool your clients find easiest usually wins on show rate.

Our take as fractional CFOs

Scheduling software is a small line in any budget, but it sits at a useful point in the revenue process: the moment a lead becomes a meeting or a client pays for a session. We look at it in three ways.

Per-seat creep. Per-seat tools grow quietly with headcount. A 20-person team on Calendly Teams pays about $3,840 a year on annual billing; on monthly billing it is $4,800. Review seats every quarter and remove anyone who no longer hosts meetings. Our business diagnostics work often finds a tool stack that has outgrown its users.

Tool consolidation. If you pay for a scheduler, a separate intake form tool and a payment link tool, check whether one product can do all three. For a service business, Acuity often replaces two subscriptions. For payment processing more broadly, see our Stripe vs Square comparison.

Conversion data. Booked meetings, show rate and meeting-to-deal conversion are funnel metrics that belong in unit economics and in monthly management reporting. Connect the scheduler to your CRM so meetings are counted once and attributed correctly; our HubSpot vs Pipedrive vs Close comparison covers the CRM side.

For a service business, prepaid packages also change cash flow: you collect cash before you deliver. That is good for working capital, but the unused sessions are a liability on your balance sheet until they are delivered. Track them.
