Does Acuity Scheduling Fit Karate Instructors? Our Read
What karate instructors need from their software, from sources outside Acuity Scheduling and outside Nexa:
Contract terms and cancellation rights are set by state law. Karate schools often fall under state health club or martial arts school statutes, and the business has to follow them. In New York, the Health Club Services Act expressly covers martial arts, including judo, karate and self-defense. Contracts cannot run longer than 36 months. Members must be able to cancel within three days of signing. They can also cancel at any time if the club stops offering the contracted services or if they move 25 or more miles from any club the seller operates. Annual renewals carry a 15-day cancellation window, and monthly renewals carry a cancellation window of the first three days of the renewal period. Clubs must accept cancellation online, by email, phone, mail or in person. Billing and records software has to track contract start dates, terms, renewals and cancellations. (ag.ny.gov)
Some states regulate martial arts schools by name. New Hampshire's RSA 358-S, titled Martial Arts Schools, gives buyers three business days to cancel in writing, and the school must refund all money collected under the contract. The required notice also says a school may have to post a bond to protect customers who pay in advance. If no bond is posted and a buyer pays more than one month's fees in advance, the buyer may lose that money if the school stops operating. Schools need to keep signed contracts and cancellation notices, and to track how much each student has prepaid. (gc.nh.gov)
Sales tax treatment of martial arts classes can differ from other services and has changed in at least one state. Washington's 2016 law made martial arts facilities charge sales tax on everything from lessons to uniforms. A later Senate bill (SB 5205) removed martial arts from the definition of retail sales, except for classes held at an athletic or fitness facility, and put classes under the 1.5 percent B&O service rate. I read this as a Senate bill report on the bill as passed by the Senate, so the final law and current rules need checking with the state revenue department. The need is to track tuition, uniforms and gear as separate revenue lines, because they can be taxed differently. (lawfilesext.leg.wa.gov)
Karate schools commonly bill several kinds of fees on top of monthly tuition. A practitioners' forum thread (posts from 2005-2006, so the figures are dated) mentions adult tuition of $50 to $65 a month and children's tuition of $35 to $50. Posters also mention a $20 setup fee, belt promotion or testing fees of $30 to $50 per student, and a yearly insurance charge of about $50 per student collected at registration. Invoicing needs to handle recurring tuition alongside one-time and annual fees. (forums.uechi-ryu.com)
Acuity Scheduling covers the scheduling side of a karate school well. Its list includes class scheduling, packages, subscriptions, gift certificates, coupons, deposits, intake forms and cancelation policies. Its higher plans add text reminders and an appointment waitlist, which help when parents need a nudge or a class fills up. Payments run through Stripe, Square, PayPal or Venmo. The gap is the legal and records side of the trade. Contract start dates, terms, renewals and cancellations have to follow state law, such as New York's 36-month cap and cancellation windows or New Hampshire's three-business-day written cancellation. Prepaid balances and signed contracts have to be kept on file. Tuition, uniforms and gear may need to be tracked as separate revenue lines for tax. Nothing in Acuity's feature list is aimed at any of that, so those records would live elsewhere.
Nexa covers more of the billing and records work. It has recurring invoices, payment plans, and invoices for one-time items such as setup, testing or insurance fees. Clients can pay by card through your own Stripe account and sign estimates in a pay portal. It also has sales tax tracking, expenses and profit and loss, a CRM with notes linked to each client, and a public booking page with intake forms, group-class capacity, and reschedule and cancel links. It does not have a waitlist or recurring booking series, and it has no text messages or calls. It has no Google Calendar sync, since calendar export is an .ics file. It also has no QuickBooks or Xero sync. Card payments go only through your own Stripe account. Its automated emails, such as reminders and sequences, send only while Nexa is open on one of your devices. It is software you run yourself, with no hosted support desk or vendor-run onboarding.
Over three years Acuity at $34/month comes to $408 a year, or $1,224. Nexa is $279 once, plus $458.64 in total if you add Cloud Sync at $4.99/month, and it runs on one device without Cloud Sync. If your main pain is tuition billing, one-time fees and tax lines, and you can handle contract and cancellation records yourself, Nexa costs far less. If you rely on text reminders to parents, a waitlist for full classes, or a hosted tool that works in a browser without you keeping an app open, stay with Acuity.
Our read for karate instructors: Stay with Acuity Scheduling if you depend on text reminders, waitlists or hosted reliability; consider Nexa only if billing, fees and tax tracking matter more and you can live without those.

Bottom Line
Acuity Scheduling costs karate instructors $408/year at today's list price. Nexa is $279 once for invoicing, scheduling, CRM, time tracking and accounting in one suite — so after 8.2 months it has cost less than Acuity Scheduling, and you own it after that. What it is not: hosted-for-you software with a support desk and a roadmap you can lobby. That is the trade, and the rest of this page is the detail behind it.
Can it pay for itself?
Nexa is $279 once, about $23 a month over its first year. Its Drain Guard reads your expenses (from a linked bank, an imported statement, or ones you type in), finds the charges that repeat, and adds them up by the month. Keep or Cut then walks you through them one at a time. Cancel $23 a month of charges you'd forgotten about and Nexa has paid for itself inside the first year, before you count the Acuity Scheduling bill you'd stop paying.
It depends on what you find and what you cancel, so we don't promise a number. In our demo data, Drain Guard finds 5 subscriptions adding up to $110.13 a month. That is sample data, not a customer's.
The verdict for karate instructors: Stay with Acuity Scheduling if the needs in our read above apply to you. If they don't, Nexa covers the core invoicing, scheduling and books for $279 once against $1,224 for Acuity Scheduling over three years.
Choose Nexa if:
You're done paying monthly forever
You're a solo operator or small team (1-5)
You need scheduler, connect crm and invoicing in one tool
You're tired of price increases
You want to own your tools like you own your equipment
Choose Acuity Scheduling if:
You have a large team (10+) needing enterprise features
You're deeply invested in Acuity Scheduling's specific workflow
You need a feature Nexa doesn't have yet
Sound Familiar?
I open the dojo, bow in, and line up the day. Afternoons and evenings are my bread and butter — kids' classes, where the real business lives. The little ones need structure and energy, so I run them through stances, basic blocks, and a kata, handing out the discipline and the fun in equal measure while parents watch from the chairs. I'm tracking which kids are close to testing for the next belt, who's mastered their kata, and who needs another cycle. Between classes a parent asks about the upcoming belt test and whether her son's ready and what the fee is, and I'm answering from memory because my eligibility list is a marked-up roster. We've got a tournament coming, so I'm collecting registration money and permission slips from a dozen families and trying to coordinate who's competing in what division. The adult evening class is smaller — more sparring, more advanced kata — and I gear them up for controlled sparring, watching for safety. Admin is relentless behind the scenes: tuition that's supposed to autopay but a few cards expired, test fees, the new student whose waiver I never got signed. I notice a couple of green belts haven't been back — that classic drop-off where the family feels they've 'done karate' once the kid has a colored belt. I close the dojo knowing I should call those parents before they're gone for good.
Belt testing happens on a cycle and I'm chasing who's eligible, who paid the test fee, and who's ready on kata
Kids' classes are the bulk of my income, which means parents, waivers, and tuition autopay I manage by hand
Tournaments require travel, registration, and permission slips I coordinate for a whole team at once
Retention drops after kids earn a few belts and parents decide they've 'done karate' and quit
Scheduling, client records and invoicing are the pieces of that day. Some tools rent you each piece separately. A few — Nexa among them — bundle the lot and carry their own booking link, with no per-appointment cut. The sections below price both routes honestly.
None of that is a software problem you can buy your way out of in one click — it is why the tool you pick matters more than what it costs. Acuity Scheduling solves some of it. So does Nexa. The difference is what you are left holding in three years.
What Acuity Scheduling Actually Costs Karate Instructors
Today's list price is $34/month — $408 a year, from Acuity Scheduling's own pricing page. Every figure below is that price, multiplied. Nothing is projected.
Three years at today's price
Year 1$408
Year 2$408
Year 3$408
Three years of Acuity Scheduling$1,224
Nexa: $279 once (or 3 × $99). Over the same three years, that is $945 less.
If Acuity Scheduling raises its price, the three-year cost goes up; if it cuts it, the cost comes down. We don't guess which. Add-ons, extra seats and card-processing fees are not included, on either side.

What "$279 Once" Does And Doesn't Buy
It buys the software, not a service contract. You install Nexa and it runs on your machine. There is no seat count, and nothing stops working if you stop paying, because there is nothing to stop paying.
Acuity Scheduling's monthly fee is not only rent. It pays for their hosting, their support desk, and their engineers shipping changes every week. If those matter to how you work, that is a real thing you would be giving up.
Cross-device sync is the one optional extra — $4.99/month if you want your data mirrored between machines. Skip it and Nexa still works; you just sync manually.
The honest risk of buying once: you are betting on us still being here to improve it. The honest risk of renting: the price is theirs to raise, and the graveyard section below is a record of tools that did exactly that.
What Acuity Scheduling Does Better
Straight from Acuity Scheduling's own feature set. If one of these is the reason you pay them, that reason does not disappear because Nexa is cheaper.
Intake forms
Package and subscription billing
Gift certificates
HIPAA compliance (Powerhouse)
Squarespace integration
A smaller bill up front: plans start at $20/month, against $279 paid once for Nexa.
Acuity Scheduling is the better call if you need intake forms specifically, or if your team is large enough that per-seat pricing still beats buying software outright.

What people outside Acuity Scheduling and outside Nexa say:
Software Finder shows a 4.5 rating from 25 reviews, with category scores of 9/10 for ease of use, value for money, customer support and functionality. The most-cited strengths are ease of use, integrations, automated email and text reminders that reviewers credit with reducing no-shows, and customizable emails and calendar views. (softwarefinder.com)
Software Finder reviewers also raise drawbacks. Some small businesses find it expensive, and one reported unresolved booking issues and slow support replies. Booking form appearance is limited, and add-ons are checkboxes only, so customers can't choose quantities. Stripe refunds need a separate login to Stripe. One business said it lacked features as its staff and resources grew, and a healthcare reviewer said it isn't suited to HIPAA-regulated practices. (softwarefinder.com)
Secret's page has no user reviews. Its editorial text calls the product user-friendly, customizable and affordable. It also lists as cons that pricing may be expensive for tight budgets, advanced features are limited, and some third-party integrations may be lacking. (joinsecret.com)

Where business tools fit — for a karate instructor
Software doesn't do your clients — it automates the business around it. And that part is the same for every karate instructor: find the work, manage it, bill for it, get paid. Each step has a tool — and the right single tool runs the whole loop, so the handoffs are automatic and you get back to your clients. Tap a step to see what gets automated.

Paid by card or link, the deposit credited, and what's overdue chased — without you doing it by hand.
Card / online payments
Automatic reminders
You can stitch four separate subscriptions across these four steps, or run one tool that does the whole flow so a booking becomes a job becomes an invoice becomes a payment without re-typing. Either way the goal is the same: less time on the business of the business, more on your clients. (Nexa is built to be the one — but the honest options for each step are above and below.)
Watch a job become an invoice
This is the connection that makes the rest worth it. A karate instructor's job already holds the services, the hours, the add-ons, and the materials — so the invoice builds itself from the work instead of you re-typing it at 9pm. Toggle an add-on or nudge the hours and watch it recompute.

What This Means for Karate Instructors
The median Karate Instructor earns $40,000/year. At $408/year, Acuity Scheduling is a recurring slice of that — paid again every year, whether the year was good or not. Owning the same jobs outright is $279 once, and the slice stops.
Nexa is $279 once. Invoicing, scheduling, CRM, time tracking, accounting — all connected, built for karate instructors. You own it like you own your Gi (karate-gi) and belt set.
Is Nexa actually right for a karate instructor?
An honest fit check — because the wrong tool is worse than no tool.
Right for you if
You run solo or a small team — like the 12,000 karate instructors in the US who do, and you wear every hat.
You're tired of paying every month for a monthly subscription stack and a pile of apps that don't talk to each other.
You want invoicing, scheduling, and client tracking in one place — not scattered across five apps.
You'd rather own your software once, the way you own your Gi (karate-gi) and belt set.
Look elsewhere if
You have a large team that needs enterprise seats, granular roles, and dedicated admin staff — Nexa is built for solo and small operators (1–5), and a bigger platform will serve you better.
You need full payroll for a large team or deep, SKU-level inventory — that's not what Nexa is for.
You're genuinely happy paying monthly and don't mind stitching tools together. No tool fixes a workflow you already like.
The honest fit: if you're a solo or small karate instructors business that owns its tools and is sick of renting software, Nexa replaces your whole stack for $279 once. If you're scaling into a large team with dedicated admin staff, a bigger platform may fit better — and we'd rather tell you that now than sell you the wrong thing.
Scheduling, client records and invoicing are the pieces of that day. Some tools rent you each piece separately. A few — Nexa among them — bundle the lot and carry their own booking link, with no per-appointment cut. The sections below price both routes honestly.

How To Read This Page
We make Nexa. It is one of the two options compared here, so read this with that in mind. We have tried to make Acuity Scheduling's case the way we would want ours made — their strengths above are their own published feature list, not our summary of it.
The prices are Acuity Scheduling's published list prices, checked on the date shown in the sources below. Plans change; check theirs before you decide.
No customer quotes appear on this page because we do not have any from karate instructors we can verify. For user testimony, read the independent reviews — Acuity Scheduling on G2 and on Capterra — where the reviewers are not selling you anything.
Check the price yourself:Acuity Scheduling's own pricing page is the source for every figure above, read on the date shown in the sources section below.
We are not neutral about subscriptions, and that is the argument, not a hidden assumption: software you pay for once is cheaper over three years than software you rent, unless you need something only the rented one does.
How we put this guide together
We build a karate instructor's guide the same way every time, and we'd rather you trust it than take it on faith. Nexa is our product, so the test we hold ourselves to is simple: a tool only "wins" a job here when it genuinely does that job better for a karate instructor — and where something free, open-source, or buy-once does it better, we say so and link you to it. Where Nexa falls short (payroll is the honest example), we name the alternative outright.
Where the numbers come from
Vendor pricingAcuity Scheduling $408/yr, Vagaro $600/yr, Square, Calendly $144/yr — taken from each company's published plans, last verified September 2026. Pricing moves; each name above links straight to that vendor’s own pricing page so you can confirm it before you decide.
Income contextThe $40,000 median we cite for the typical karate instructor is occupational median annual pay from the U.S. Bureau of Labor Statistics (Occupational Employment & Wage Statistics), compiled April 2026. We use it only to show software spend as a share of real income — your own numbers will differ.
Three-year mathMulti-year totals are today's list price multiplied by the number of years. No price rise is projected, so the figure can be checked against the vendor's own pricing page; if they raise it, the real cost is higher.
