Acuity Scheduling vs Nexa The Real Comparison for Scuba Instructors
Acuity Scheduling
$34/mo ($408/yr)
VS
Nexa
$279 once — own forever
or 3 payments of $99
Break even: 8.2 months at Acuity Scheduling's current price.
Bottom Line
Acuity Scheduling costs scuba instructors $408/year at today's list price. Nexa is $279 once for invoicing, scheduling, CRM, time tracking and accounting in one suite — so it pays for itself in 8.2 months 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.
The verdict for scuba instructors: Acuity Scheduling is solid software, but at $34/month it costs $1,224 over 3 years. Nexa does most of what Acuity Scheduling does for $279 once. For solo scuba instructors and small teams, Nexa is the better deal.
Choose Nexa if:
You're done paying monthly forever
You're a solo operator or small team (1-5)
You need scheduler, Connect CRM, Invoicing in one purchase 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
What Acuity Scheduling Actually Costs Scuba 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.
Where business tools fit — for a scuba instructor
Software doesn't do your clients — it automates the business around it. And that part is the same for every scuba 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.
1
Find the work
Get booked
↓
A new client finds you and books a time — no phone tag, no double-booking.
CRM / contacts
Estimates & proposals
Booking / scheduling

2
Manage the work
Deliver the service
↓
The session itself — with the client history, notes, packages, and add-ons right there instead of in three different places.
Job / project tracking
Time tracking
Expenses, materials & add-ons

Bill for it
Send the bill
↓
The work becomes the invoice — the hours, the add-ons, the materials, the deposit credited — totaled and sent, instead of re-typed at 9pm.
Invoicing
Deposits & credits

4
Get paid
Collect payment
↓
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 scuba 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.

Sound Familiar?
Mornings start at the dive shop loading tanks and checking that every regulator breathes clean before it goes on a student's back. The confined-water session is in the pool: you brief the skills on a slate, then descend with two or three students and run them through mask clearing, regulator recovery, and the air-share drill, watching their eyes for the panic that comes when water hits their face for the first time. One student bolts for the surface on the mask skill and you're right there, slowing the ascent, getting them calm, then patiently rebuilding the skill in the shallow end before moving on. After lunch you load the boat for an open-water checkout dive, going over the dive plan, hand signals, and turn-pressure on the ride out. Underwater you demonstrate each skill kneeling on the sand, then have each student repeat it while you hover close enough to intervene. You're constantly checking everyone's air and depth, herding the group, and deploying the surface marker before the ascent. Back on the boat you debrief, log each diver's completed skills, and high-five the new certified divers. The gear gets rinsed, the tanks go back for fills, and you update who still needs a second checkout dive before the season's clear days run out.
A student panics on a mask-clearing skill at depth and you have to manage their air, their fear, and the rest of the group at once
Air fills and tank rentals have to be coordinated with the dive shop, and a short fill can cut a training dive short
Weather and visibility can kill a checkout dive that's been booked for weeks, and the window to certify is tight
Tracking which of the five open-water skills each student has actually completed before you sign their card
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 This Means for Scuba Instructors
The median scuba 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 scuba instructors. You own it like you own your PADI or SSI open-water instructor certification.
Is Nexa actually right for a scuba 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 scuba 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 PADI or SSI open-water instructor certification.
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 scuba 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.

What Nexa does for a scuba instructor — and what it doesn't
The honest version. Nexa was built to beat the rented stack on the jobs that matter most to a scuba instructor — here's where it wins, where the integration wins it anyway, and the things it genuinely doesn't do, with who to use instead. (No tool is best at everything; a guide that pretends otherwise is just an ad.)
Compare the essential business tools for scuba instructors
The usual subscriptions vs. Nexa, side by side. Drag the time slider — every year you keep renting, the gap widens. Nexa is $279, one time.
The reason it wins the set: Your booked confined-water and checkout dives, each student's cleared skills, and the fees-plus-fills live in one record, so a weather-killed window never scatters your schedule, your skill log, and your billing. in one record — $279 once vs 3 subscriptions · ~$900/yr.
What Nexa takes off your plate
Scheduling & bookingvs Calendly →Because a checkout dive booked weeks out can die on weather and visibility with a tight window to certify, rebooking it in one record beats juggling the dive shop's calendar against your own.
CRM & clientsvs HubSpot →Tracking which skills each student has cleared on the same record you booked means you know who still needs mask-clearing before the next descent, instead of checking a separate slate after the session.
Invoicingvs FreshBooks →Since air fills and tank rentals coordinated with the shop attach to the dive you ran, billing flows from that record instead of re-entering students into a separate invoicing app.
When you run big email campaigns & automations→ ConvertKit →

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 scuba 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.
Some links on this page earn us money. Tool links may be affiliate links paying us a commission at no extra cost to you, including links to Acuity Scheduling itself. We list a tool when it is the honest pick for the job, not because of the payout.
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 scuba 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 scuba 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 scuba 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.
