The real cost of esthetician software: add-ons, processing rates, and what's actually included

September 28, 2026 · 5 min read

Every few weeks someone in a facebook group asks what a particular booking app costs, and gets fourteen different answers. All of them are right. That's the problem.

The number on a pricing page is a starting bid. What you actually pay depends on which features you turn on, how you take payment, and how much money goes through the system. Two people on the same plan can pay very different amounts.

So rather than give you numbers that will be out of date by the time you read this, here's how to work out your number. It takes about ten minutes and a look at last month's statement.

Layer one: the plan

Start with the advertised monthly price, then check two things about it.

Does it scale? Some plans are priced per bookable calendar, per staff member, or per location. If you're solo, you're on the cheapest rung and it stays there. Worth knowing anyway, in case you ever take on help.

Is it annual or monthly? Annual is usually cheaper per month and is also a year of commitment to something you've used for a week. There's nothing wrong with paying monthly at first.

Layer two: the add-ons

This is where the gap opens up. A base plan is often booking and payments. The things an esthetician actually needs day to day are frequently priced separately.

Go through the feature list and mark which of these are included and which cost extra:

  • Intake and consent forms
  • Anything described as charting, SOAP notes, or clinical records
  • Photo storage, and whether there's a limit
  • Email or text marketing, and whether messages are metered
  • Automated reminders, and whether texts cost per message
  • A booking website or widget
  • Memberships, packages or gift cards

You don't need all of that. But you do need whichever of them you're currently paying a second app for, and that's the honest comparison: not base plan versus base plan, but everything you actually use versus everything you actually use.

Layer three: processing, which is usually the biggest number

Here's the part that surprises people, and it's just arithmetic.

A subscription is a flat monthly amount. Card processing is a percentage of everything you take. Once your revenue is past a certain point, the processing dwarfs the subscription, and a difference of a few tenths of a percent matters more than the entire plan price.

Work out your own figure:

  1. Take your card revenue for last month.
  2. Multiply it by the rate you're quoted. Rates are usually written as a percentage plus a few cents per transaction, so if yours has both, also multiply your number of transactions by that per-transaction amount.
  3. Add those together. That's your monthly processing cost.

Now do it again with a rate that's half a percentage point different and see what changes. On most treatment-room businesses that swing is larger than the subscription you were agonising over.

Two things to check specifically:

The card-not-present rate. Tapping a card in person and keying a number in over the phone are usually charged at different rates, and the keyed-in one is higher. If you take deposits by phone or keep cards on file for no-shows, ask what that rate is, not the headline one.

Who sets it. If the software has its own processing baked in, the rate comes with the software. If it works with a processor you already have, you keep whatever rate you already negotiated.

Layer four: the fees you meet later

These rarely appear on a pricing page, so ask directly:

  • Is there a fee to get your money the same day, rather than waiting the standard payout?
  • Is there a commission on clients who find you through the company's own marketplace, and does it apply once or to every booking that client ever makes?
  • Is the card reader bought, leased, or rented monthly?
  • What's the chargeback fee?
  • Is there a cancellation or early termination fee on an annual plan?

None of these make a product bad. Being surprised by them six months in is what makes people angry.

The cost nobody puts on an invoice

Switching. Moving your clients, rebuilding your services and hours, relearning your own diary, telling regulars the booking link changed, and the week where you're slower at everything.

That cost is real, it's front-loaded, and it's the single biggest reason people stay somewhere they've outgrown. It's worth counting honestly on both sides of the decision: it argues against switching for a small saving, and it argues for switching properly if the thing genuinely doesn't fit.

It's also why SlickChart connects to your existing Square account rather than replacing it. If booking and payments already work, the thing you're short of is the chart, and you can add that without paying the migration cost at all. If your booking genuinely isn't working, that's a different decision and an all-in-one may be the right answer.

The four questions

Ask these of anything you're considering, including mine:

  1. What does this cost with everything I actually need switched on?
  2. What are both processing rates, in person and keyed in?
  3. What fees exist that aren't on the pricing page?
  4. If I leave, can I export my clients, my notes and my photos?

A company that answers all four plainly is telling you something about how the rest of the relationship will go.

If you want the wider version of how to judge software beyond price, that's here, and if you're working out whether the spend is earning its place at all, the arithmetic of a treatment-room business is here.
