Calendly is excellent at solving a specific problem: getting someone to pick a time without the back-and-forth of scheduling by email. For that use case, it works well. For service businesses that need customers to commit financially at the moment of booking, it doesn't work at all. Calendly does not collect deposits.
If your problem is no-shows and last-minute cancellations, a plumber who drives 40 minutes to a house that's locked, a personal trainer whose client texts to cancel at 6 AM, a mobile groomer whose van was loaded and the pet owner isn't home, you need something that goes beyond scheduling logistics. You need a tool that collects a deposit when the customer books. Here's what that looks like across your main options.
Why Calendly doesn't solve the no-show problem
Calendly makes booking frictionless for customers, which is part of the problem. A frictionless booking with no financial commitment is a weak commitment. The customer fully intends to show when they click "Book." But intention fades, other things come up, and the cost of cancelling is zero. They don't call. They don't text. They just don't show.
A deposit changes this because it activates loss aversion. Once a customer has paid $50 to hold a slot, not showing costs them $50. That is a real, immediate loss that most people work to avoid. Calendly's paid meeting feature isn't a deposit, it's a fee for the meeting itself, not a refundable hold that gets applied to the service. The distinction matters behaviorally.
The alternatives compared
| Tool | Monthly cost | Deposits | Calendar sync | Best for |
|---|---|---|---|---|
| GrabMySlot | No monthly fee (3% per deposit) | Yes, core feature | Google + Outlook | Service businesses needing deposit-first booking |
| Acuity Scheduling | $20 to $61/mo | Yes | Google, Outlook, iCal | Wellness and beauty with complex scheduling needs |
| Square Appointments | Free to $29/mo | Yes | Google only | Businesses already using Square for payment |
| Setmore | Free to $9/user/mo | Pro plan only | Google + iCal (Pro) | Very basic scheduling, minimal deposit needs |
| SimplyBook.me | $9.90 to $59.90/mo | Yes | Google + iCal | Businesses needing multi-location or staff management |
| Calendly | Free to $16/user/mo | No | Google, Outlook (iCal | Meeting scheduling only) not for service businesses |
GrabMySlot
GrabMySlot was built specifically for service businesses that need deposit-first booking. There is no monthly fee, you pay 3% only when you collect a deposit, which typically works out to $15 to $45 per month at typical service business volumes, and zero in slow months. Setup takes under five minutes. The booking page displays your cancellation policy before payment so there's no ambiguity about what the customer agreed to. Calendar sync covers Google Calendar and Outlook.
It doesn't have CRM, invoicing, or multi-location management. It does one thing well: takes a deposit when someone books, sends automated reminders, and syncs to your calendar. For providers whose main problem is no-shows rather than back-office management, that's the right scope.
Acuity Scheduling
Acuity handles deposits and has a solid feature set for businesses with complex scheduling needs, multiple staff, intake forms, packages, and subscriptions. The Emerging plan at $20/month doesn't include deposits; you need at least the Growing plan at $34/month. For a solo service provider who needs basic deposit collection, that's more than necessary. For a wellness studio managing five practitioners with varying availability, Acuity is worth the cost.
Square Appointments
Square Appointments includes deposit collection and is free for solo providers. The catch: it only syncs with Google Calendar, not Outlook, and it works best if you're already in the Square payment ecosystem. For a contractor who takes Square card payments in the field, adding Square Appointments for online booking is a natural extension. For someone not already on Square, the payment processing setup adds friction.
Setmore
Setmore has a free tier but deposit collection requires the Pro plan at $9 per user per month. The feature set is basic. It works for very simple scheduling needs but isn't built for the specific requirements of field service or trades businesses where no-show prevention is the primary goal.
Which one to choose
If your main problem is no-shows and you want to minimize monthly overhead: GrabMySlot. The 3% model means you're only paying when you're actively collecting deposits, and the tool is built around that specific use case.
If you need complex scheduling across multiple staff with intake forms and package management: Acuity at $34/month or SimplyBook.me. Both are more capable and more expensive than the problem typically requires for a solo or small-team operator.
If you're already in the Square ecosystem and your customers are comfortable with Square: Square Appointments is the path of least friction.
If you just need scheduling links and genuinely don't have a no-show problem: Calendly's free tier is fine. But if no-shows are costing you money, Calendly is solving the wrong problem.
