Most plugin features are conveniences. These two are not. Text reminders and deposits are the only settings in a booking system that produce a number you can put against the licence fee, and for most appointment businesses that number clears the fee within a month.

The arithmetic is simple enough to do on the back of a receipt. If a missed appointment costs you the full value of the slot, and text reminders cut your no-show rate by even a few percentage points, recovering one appointment a month pays for almost any plugin here. This article works through those numbers, maps which tier each product puts text messaging in, and covers the messaging costs that sit on top of the licence.

Verified August 2026. Plugin prices are vendor list prices; messaging gateway rates vary by country and change frequently, so price your own volume.

What a no-show actually costs

The instinct is to count the lost fee. The real figure is higher, because the cost has three parts and most businesses only notice the first.

The slot value. A three-hour colour appointment, a therapy session, a dental hygiene visit. The practitioner is present and paid regardless, so the entire fee is gone rather than just the margin.

The turned-away booking. The slot was unavailable to everybody else, so a client who wanted it went elsewhere. On a busy Saturday this frequently doubles the cost of the miss.

The follow-up. Somebody calls, rebooks, updates the calendar. Fifteen minutes of paid time, plus the awkwardness.

Put rough numbers on it. A salon losing four appointments a month at an average of 60 in local currency is losing 240 in fees alone, and closer to 400 counting turned-away slots. A clinic charging 120 an hour and missing six appointments a month is well past 700. Against that, a plugin licence between $63 and $399 a year is not a meaningful expense; it is a rounding error against a problem you can partly fix.

Text versus email, and what each costs

Email reminders are free and largely ignored. Text messages cost a few pence each and are read within minutes. That difference is the entire argument, and the economics favour text overwhelmingly.

• Price your own volume before deciding. A hundred appointments a month at one reminder each, at typical gateway rates, is a small monthly figure that most businesses find trivially affordable once they compare it to one recovered appointment.
• Send one text, not three. Confirmation by email, reminder by text at twenty-four hours. Additional messages annoy people and multiply the cost without improving attendance.
• Keep messages short. Gateways charge per segment, and a long message becomes two. Date, time, business name and a cancellation link fits comfortably in one.
• Check international rates if you have overseas clients. Per-message pricing varies enormously by destination country, and an unexpected bill is usually an international one.
• Get consent for messaging. A tick box at booking, and honour opt-outs. Marketing rules apply differently to transactional reminders in most jurisdictions, but consent is cheap insurance.
• Include a cancellation link in the text. This is the single highest-value element, because it converts a would-be no-show into a slot you can refill.

Two ways of paying exist. Most plugins connect to a messaging gateway where you hold the account and pay per message, which is cheapest and gives you control. A few resell credits, which is simpler to set up and more expensive per message. At low volume the difference is negligible; above a few hundred messages a month, hold your own gateway account.

Configuring deposits so they work

A deposit is a commitment device, not a revenue stream. Configure it to change behaviour rather than to collect money, and it does both.

Charge on long services only. Twenty to thirty per cent of a high-value appointment is meaningful enough to change behaviour without deterring the booking. A deposit on a short, cheap appointment is friction with no return.

Set the cancellation window to match your refill speed. Forty-eight hours if the slot is hard to fill, twenty-four otherwise. Refund fully inside the window, keep the deposit outside it, and say so plainly.

Show the terms before payment, in plain language. A policy discovered after the fact will not survive a dispute, and disputes cost you the payment plus a fee plus the relationship. One clear sentence at the point of payment prevents nearly all of them.

Enforce it consistently or lower it. A rule waived whenever somebody objects trains clients to object. Decide what you will actually do, write that down, and apply it the same way each time. A modest deposit you always enforce protects more revenue than a large one you never do.

Frequently asked questions

Do text reminders really reduce no-shows?

Substantially more than email, because texts are read within minutes and email frequently is not read at all. Recovering one appointment a month typically covers the plugin and the messaging cost together.

How much does text messaging cost on top?

You pay the gateway per message, at rates that vary by country. Price your own monthly volume, keep messages to one segment, and check international rates separately.

How large should a deposit be?

Twenty to thirty per cent of a high-value service is enough to change behaviour. On short or inexpensive appointments a deposit costs you bookings for very little protection.

When should the reminder be sent?

Twenty-four hours ahead, so there is a working day to refill the slot. Include a one-tap cancellation link, which converts a no-show into a fillable gap.

Which plugin is cheapest for deposits?

FluentBooking at $63 a year includes payments at its entry tier, which is the cheapest route to the single most effective no-show control available.

Do I need consent to send reminder texts?

Transactional reminders are treated differently from marketing in most jurisdictions, but a tick box at booking and an honoured opt-out is cheap insurance and good practice.

The verdict

For both features configured properly: Amelia from $149, with built-in text notifications, editable templates and per-service partial payments so deposits apply where they matter.

For the cheapest deposit protection: FluentBooking at $63, since payments at the entry tier make the highest-value no-show control available for less than any alternative here.

For a non-technical operator: Simply Schedule Appointments at $199, where the clarity of the reminder configuration is worth the premium because a system nobody understands eventually stops working.

Then set it up the way that actually works. One text at twenty-four hours with a cancellation link, a deposit on long services only, terms shown before payment, and consistent enforcement. Do that and one recovered appointment a month pays for everything on this page.
