tilkbook vs Acuity Scheduling — free booking comparison

tilkbook vs Acuity Scheduling: the quick answer

Acuity Scheduling and tilkbook both serve service businesses booking client appointments, but they differ in two structural ways: cost and appointment-specific safeguards. Acuity requires a paid subscription after a short trial — there is no permanent free tier. tilkbook’s booking product is genuinely free with no time limit, no credit card required, and no seat or booking cap. On top of that, tilkbook adds no-show and late-cancellation fees, an automatic waitlist that fills empty slots, and a slot-hold during checkout — three workflows Acuity does not offer. Acuity’s real advantages are its native Squarespace integration and pre-built package bundles and gift certificates, which are legitimate reasons to stay if those fit your business. This page covers all the differences in enough detail to make an informed call.

How does the pricing compare?

The core pricing difference is categorical: tilkbook’s booking product has no subscription tiers. Unlimited bookings, unlimited staff, full admin features, a REST API, and outbound webhooks are all free. The only paid option is the Stripe payments add-on, which enables deposits, full payment at booking, tips, no-show fees, refunds, and discount codes. Precise add-on pricing is still being finalised — but the baseline booking product costs nothing, ever.

Acuity Scheduling starts with a 7-day free trial and then requires a paid plan starting around $16/month (last verified 2026-06-26 — always check acuityscheduling.com/pricing before quoting). Plans are tiered with progressively more features: package bundles and gift certificates are on a higher-tier plan, and the REST API is unlocked only on the top-tier plan.

For a solo massage therapist, personal trainer, tutor, or small studio weighing their first booking tool, the free-forever baseline versus a required monthly subscription is often the deciding factor.

Which has a better free tier?

tilkbook, clearly. Acuity has no permanent free tier — the free trial is seven days, after which you must subscribe or lose access to your booking page. tilkbook’s free tier is permanent, unlimited, and includes every admin feature: calendar, staff management, customer records, waitlist, recurring appointments, embed widget, email reminders, and the REST API. The only gate to going live is a setup-completeness check (at least one active service, business hours set, at least one active staff member), which is a sanity check, not a paywall.

For a business owner who wants to try the product on real bookings before deciding whether to connect payments, tilkbook’s free tier provides an unlimited runway. Acuity’s seven-day window is too short for most service businesses to evaluate real-world booking flow.

Which handles no-shows better?

This is one of tilkbook’s clearest advantages over Acuity. Acuity Scheduling has no native no-show fee mechanism — if a client does not show, the appointment revenue is simply lost through the platform. For a salon chair, a massage table, or a personal training slot, an empty appointment is a direct cost.

tilkbook treats no-shows as a first-class problem. With the payments add-on, you can charge a no-show or late-cancellation fee off-session against the card the client used at booking — automatically, with Stripe 3-D Secure re-authentication when required. You can also excuse a no-show when a client had a genuine reason (so you are not punishing a loyal client for one bad day), and retry a failed no-show charge. Pair this with deposits collected at booking time and the financial exposure of empty slots drops significantly.

Which handles payments and deposits better?

Both tools collect payment at booking, but their payment models are structured differently. tilkbook’s Stripe payments add-on covers the full transaction lifecycle for a service business: collect a deposit or full payment at booking, add tip collection, apply discount codes, and charge a no-show or late-cancellation fee after the fact if the client does not show. Refunds and dispute management with evidence submission are built into the admin. When the payments add-on is off, the booking page degrades gracefully to pay-on-site — the booking itself always works.

Acuity supports Stripe, Square, and PayPal on all paid plans, and packages payments cleanly into the booking flow. What Acuity does not offer is the no-show fee charged after an appointment — its payment model is forward-looking (collect now), while tilkbook covers the full lifecycle including the missed-appointment scenario.

Which has a better waitlist?

Acuity Scheduling does not have a built-in waitlist. tilkbook’s waitlist is a fully automated FIFO queue. When a booking is cancelled, rescheduled, or marked as a no-show, the system automatically emails the next matching waitlisted client an offer to claim the freed slot, with a time-limited claim link. The claim is atomic — if two waitlisted clients try to take the same slot simultaneously, only the first click succeeds and the second sees a “slot already taken” message. No manual admin step is needed.

For a business with popular time slots that fill quickly — a senior stylist on a Saturday, a popular class time, a specialist practitioner — the waitlist turns cancellations from lost revenue into filled appointments automatically.

Which prevents double-booking better?

tilkbook adds a slot-hold during multi-step checkout: when a client selects a time, that slot is held for a short window while they complete the booking form. A second client browsing simultaneously will not see the held slot as available. Acuity does not offer a slot-hold mechanism, so two clients could theoretically select the same time during concurrent sessions, resulting in a double-booking conflict.

For a low-volume business, this rarely matters. For a busy salon, clinic, or popular solo practitioner where multiple clients may be browsing simultaneously during peak hours, the slot-hold prevents a frustrating double-book and the client-service effort that follows.

Which is better for per-staff scheduling?

Both tools give each staff member their own service menu and availability — a core shared strength. tilkbook builds out further with per-staff time-off and holidays, a per-staff Google Calendar sync toggle, and role-based team management. When a staff member leaves, you can bulk-reassign all of their upcoming bookings to a replacement with substitute-staff suggestions and a conflict-preview before committing.

Acuity manages multiple calendars per account and per-calendar service menus. The team management model is similar at the core; tilkbook adds the bulk-reassignment and departure-workflow layer.

Which has better calendar sync?

Acuity offers two-way sync with Google Calendar, iCloud, Office 365, and Outlook on all paid plans. tilkbook offers two-way Google Calendar sync — it reads a staff member’s Google Calendar to block busy slots and writes confirmed bookings back, with push webhooks for near-real-time updates and automatic Google Meet links on virtual services. For Outlook and Apple Calendar, tilkbook uses read-only ICS feeds: paste the calendar’s public ICS URL and its busy events block your tilkbook availability. That covers the most common need (preventing double-booking with an existing personal calendar) without a two-way write, but for teams who actively schedule meetings in Outlook and need that back in tilkbook — it is one-way.

See the Google Calendar integration and the Outlook Calendar integration for details on each mechanism.

Which is better for developers?

tilkbook’s REST API with API keys and outbound webhooks are available on the free tier — no paid plan required. Acuity restricts API access to its top-tier plan. For a developer who wants to integrate booking data into a CRM, analytics pipeline, or custom workflow without a monthly subscription gate, tilkbook’s position is meaningfully better. See the API and webhooks integration page for the full developer surface description.

Where Acuity Scheduling wins

It is worth being clear about Acuity’s genuine advantages:

• Native Squarespace integration is Acuity’s most decisive advantage for businesses on Squarespace. Because Acuity is owned by Squarespace, the booking embed is a native block rather than a third-party script. For a studio or practitioner whose website is already built on Squarespace, this friction-free embed is a real reason to stay.
• Package bundles and gift certificates are available on Acuity’s higher-tier plans. If your business sells multi-session prepaid blocks (five training sessions for one price) or gift certificates, Acuity handles these natively. tilkbook does not support either today.
• Established user community — Acuity has been in market for many years and has a large review base on G2, Capterra, and Trustpilot, as well as a community of users sharing templates and tips. For buyers who weight peer validation heavily, this track record matters.
• Broader native calendar sync — Acuity’s two-way iCloud and Office 365 sync is native; tilkbook handles these via read-only ICS feeds.

Which should you choose?

Choose tilkbook if you want a permanent free tier with no time limit, no credit card, and no booking cap — and if no-show fee protection, an automatic waitlist, and slot-holds during checkout are important to your business. These three workflows, all absent from Acuity, protect the appointment-based revenue that service businesses depend on.

Choose Acuity Scheduling if your website is on Squarespace and you want the native booking block, if package bundles or gift certificates are active parts of your revenue model, or if Acuity’s long track record and established peer reviews matter to your buying decision.
