Calendly is a scheduling tool that gives you a personal booking link. Share it anywhere, your email signature, your website, a text message, and customers or clients click it to pick a time from your available slots. Your calendar fills up automatically.
What makes it special is how smooth the experience is for the person booking. They see only the times you've made available, they pick one, they fill in their details, and they're confirmed, all in under 2 minutes. No back-and-forth emails. No phone tag.
The free plan includes unlimited 1-on-1 bookings, automatic confirmation emails, and integration with Google Calendar and Outlook. That's enough for most solo business owners to get started.
Acuity (owned by Squarespace) is a step up in complexity from Calendly, and it's worth it if you need features that Calendly's free plan doesn't offer. It's particularly strong for businesses where you need to gather information before the appointment (medical intake forms, style preferences, health history) and for businesses with multiple service types at different prices.
The intake form builder is genuinely excellent. You can ask any question you want, make fields required, and have the answers appear in your appointment notes automatically. A new customer books a color treatment, tells you their hair history, and you see it all before they walk in the door.
Calendly has the best free plan for simple 1-on-1 scheduling, unlimited bookings, automatic confirmations, and calendar syncing at no cost. If you have up to 4 staff and need a free multi-staff calendar, Setmore's free plan is unbeatable. Square Appointments is completely free for solo service businesses who already use Square for payments.
When a customer books an appointment, the system automatically sends them a confirmation email immediately and reminder emails/texts at set intervals, typically 24 hours and 2 hours before the appointment. This happens with zero work from you. The reminders include a link to reschedule, which means fewer last-minute calls. Most businesses see 30–40% fewer no-shows within the first month.
Yes, that's the whole point of online booking. You set your availability once (e.g. Monday–Friday 9am–5pm) and the software shows only those slots to customers. They can book at 11pm on a Sunday and it goes straight into your calendar. No calls, no texts, no friction.
If no-shows are a problem, yes. Requiring even a small deposit (10–20% of the service cost) dramatically reduces no-shows because people have money on the line. Acuity and Square Appointments both support deposits at booking. Calendly requires the paid plan plus a Stripe integration.
All four tools give you a booking link and an embed widget. The link you can share anywhere, your website's "Book Now" button, your Instagram bio, your email signature. The embed widget lets customers book without leaving your website. Our tutorial walks through every step.
