Does Wave Fit Swimming Instructors? Our Read
What swimming instructors need from their software, from sources outside Wave and outside Nexa:
Track instructor certifications and their expiry dates. Some venues require swim instructors to submit a valid, nationally recognized Water Safety Instructor certification and a Lifeguard/CPR certification. DC Parks and Recreation says the certification must be valid at the time of submission to its Permit Office. (dpr.dc.gov)
Store proof of liability insurance and its limits. DC Parks and Recreation requires commercial general liability of at least $1,000,000 per occurrence and $2,000,000 aggregate. It also requires sexual/physical abuse and molestation coverage of $1,000,000 per occurrence and $2,000,000 aggregate. The coverage must be an affirmative endorsement, because silent coverage is not accepted. Workers' compensation is required only if the Permit Office deems it applicable. (dpr.dc.gov)
Bill by session, and handle make-ups and credits. One university swim program enrolls and charges for a whole session, not pay-as-you-go. Late starters are prorated, and a class change after payment carries a $30 fee. Only one make-up lesson is allowed per session, and it must be used within that session. If no class time is open, the student gets a credit and no refund. Medical credits need a written note from a licensed practitioner and must be used within one session. Software needs to record these credits, expiry rules and proration. The page also contains a conflicting line saying no refunds or credits are offered for missed classes. (sjsu.edu)
Worker classification affects how instructors are paid and reported for tax. After a routine audit, the IRS decided that the City of Dana Point's recreation class instructors had been wrongly classified as independent contractors and should be treated as employees for federal employment tax purposes. The city appealed to the U.S. Tax Court. The article is from 2010 and is about recreation class instructors in general, not swim instructors specifically. The article does not report the outcome of the case. Anyone who hires assistant instructors needs records that show whether each one is an employee or a contractor. (westerncity.com)
Many instructors are self-employed and work irregular hours. The Bureau of Labor Statistics lists self-employed workers among the largest employers of fitness trainers and instructors, with a value of 15, which appears to be a percentage. It also says many work variable or part-time schedules that include nights, weekends or holidays. The BLS page does not mention swimming, so this applies to fitness instruction generally. Scheduling and income tracking need to handle uneven, evening and weekend work. (bls.gov)
Wave is an accounting and invoicing tool, and it covers the money side of swim instruction well. It has unlimited invoices and bookkeeping on its free Starter plan. On Pro it adds bank import, receipt capture, late-payment reminders and user roles. It also offers a payroll add-on and a tax-professional role, which matters if you hire assistant instructors. You would need records showing whether each one is an employee or a contractor. Wave has no class booking, no capacity limits and no intake forms. It also has no place to track instructor certifications and expiry dates, liability-insurance proof and limits, or make-up lessons and credits. You would keep those in a spreadsheet or folder outside Wave.
Nexa covers more of the scheduling and session-billing side. It has a public booking page with intake forms, group-class capacity, and reschedule and cancel links. It also has invoices, recurring invoices, payment plans, and a client pay portal that runs through your own Stripe account. For bookkeeping it has expenses, bank reconciliation, profit and loss, and 1099 summaries. Time tracking and a payroll CSV of hours times rate help with assistants. Nexa does not run payroll: it has no payroll taxes, pay stubs or direct deposit. It has no waitlist and no recurring booking series. It has no field for certification expiry, insurance limits or make-up credits, so those records stay outside the software, as with Wave. Its automated emails and reminders send only while Nexa is open on one of your devices. It has no QuickBooks or Xero sync, and it is software you run yourself, with no hosted support desk or vendor-run onboarding.
Over three years, Wave Pro at $19 a month comes to $684, or $228 a year. Nexa is $279 once, or 3 payments of $99. Adding optional Cloud Sync at $4.99 a month brings it to $458.64 over the same period. If you teach alone, sell sessions or classes, and want booking, payment plans and cheaper long-run costs, Nexa fits better. If you already use Wave and mostly send invoices, or you have assistants and rely on Wave's payroll add-on, stay with Wave. Neither tool replaces a separate record of certifications, insurance and make-up credits.
Our read for swimming instructors: Solo instructors who sell class sessions may prefer Nexa's booking and lower three-year cost, while anyone running payroll for assistants should stay with Wave.

Bottom Line
Wave costs swimming instructors $228/year at today's list price. Nexa is $279 once for invoicing, scheduling, CRM, time tracking and accounting in one suite — so after 14.7 months it has cost less than Wave, 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 Wave 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 swimming instructors: Either can do the job, for the reasons in our read above. On price alone, that is $279 once against $684 for Wave 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 Wave if:
You have a large team (10+) needing enterprise features
You're deeply invested in Wave's specific workflow
You need a feature Nexa doesn't have yet
Sound Familiar?
You rent pool time 4 hours/day at $35/hour ($140/day). Today: 2 group classes (6 kids each, $30/kid/lesson), 2 private lessons ($60/30 min), and 1 adult swim session ($50/45 min). Revenue: $360 + $120 + $50 = $530. Pool rent: $140. Net: $390 for 4 hours. But a group class had 2 no-shows ($60 in lost revenue) and you couldn't fill those spots. Summer wait list has 40 families. Winter? Maybe 10.
Pool rental costs ($30-50/hour) make scheduling optimization critical
Weather cancellations for outdoor pools
Group class vs. private lesson scheduling
Seasonal demand (summer peak, winter drop)
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. Wave solves some of it. So does Nexa. The difference is what you are left holding in three years.
What Wave Actually Costs Swimming Instructors
Today's list price is $19/month — $228 a year, from Wave's own pricing page. Every figure below is that price, multiplied. Nothing is projected.
Three years at today's price
Year 1$228
Year 2$228
Year 3$228
Three years of Wave$684
Nexa: $279 once (or 3 × $99). Over the same three years, that is $405 less.
If Wave 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.
Wave'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 Wave Does Better
Straight from Wave's own feature set. If one of these is the reason you pay them, that reason does not disappear because Nexa is cheaper.
Free plan covering unlimited invoices and bookkeeping
Bank transaction import on Pro
Receipt capture
Late payment reminders
Simple enough to run without an accountant
A free plan to start on (with limits), so you can use Wave before paying anything.
Wave is the better call if you need free plan covering unlimited invoices and bookkeeping specifically, or if your team is large enough that per-seat pricing still beats buying software outright.
What Wave Is Built For
Wave says it is built for small business owners and solopreneurs at every stage, not accountants. Its page names freelancers, contractors and consultants. (waveapps.com)
The Starter plan costs $0 and includes unlimited estimates, invoices, bills and bookkeeping records. (waveapps.com)
Pro costs $19 USD a month or $190 USD a year. It adds automatic bank transaction import (for banks Plaid supports), automatic merging and categorizing of bank transactions, and automated late-payment reminders at 3, 7 and 14 days after the due date. (waveapps.com)
Pro lets you put your logo and brand colors on invoices, remove Wave branding from footers, and attach files to invoices and estimates. It also adds user roles (admin, editor, viewer), and the payroll manager and Block Advisors tax pro roles are free. (waveapps.com)
Online card payments on Starter cost 2.9% + $0.60 (Amex 3.4% + $0.60). On Pro the first 10 transactions each month are 2.9% + $0, then 2.9% + $0.60. (waveapps.com)
Wave Advisors starts at $149 a month and includes a dedicated bookkeeper and monthly financial statements. Payroll is an add-on starting at $25 a month in one region and $40 in the other; the page does not say which price applies where. (waveapps.com)
Wave lists a mobile app for invoices, expenses and receipts, and 256-bit SSL encryption with PCI-DSS Level 1 certification. Live chat and email support runs Monday to Friday, 9 AM to 4:45 PM Eastern, and is tied to optional add-ons. (waveapps.com)
What people outside Wave and outside Nexa say:
NerdWallet lists a free plan and straightforward invoicing as pros. Its cons are no built-in third-party integrations, no advanced features such as mileage, time tracking or inventory, no live support unless you pay, and no audit trails. (nerdwallet.com)
NerdWallet says "An overwhelming number of Wave reviewers criticize its customer support." It adds that the paid plan "doesn't address Wave users' biggest complaint: customer service." (nerdwallet.com)
Tech.co praises the free tier, affordable add-ons and the way Wave "does the basics well." It concludes "Wave is definitely worth it" for side businesses that don't need specialist accounting features. (tech.co)
Tech.co criticizes Wave for lacking advanced features such as budgeting, cash flow projections, stock handling and project accounting, and for struggling to scale with growing businesses. It also says phone and live chat support come at a premium. (tech.co)

Where business tools fit — for a swimming instructor
Software doesn't do the actual work — it automates the business around it. And that part is the same for every swimming 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 the actual work. Tap a step to see what gets automated.
1
Find the work
Land the client
↓
An inquiry becomes a proposal becomes a signed engagement — the terms and the retainer set.
CRM / contacts
Estimates & proposals
Booking / scheduling
then ↓
2
Manage the work
Do the work
↓
The work you're paid for — with the hours, tasks, and expenses tracked against the engagement instead of reconstructed at month-end.
Job / project tracking
Time tracking
Expenses, materials & add-ons
then ↓
3
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
then ↓
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 the actual work. (Nexa is built to be the one — but the honest options for each step are above and below.)

What This Means for Swimming Instructors
The median swimming instructor earns $32,000/year. At $228/year, Wave 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 swimming instructors. You own it like you own your Swim teaching aids (kickboards, noodles).
Is Nexa actually right for a swimming 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 15,000 swimming instructors in the US who do, and you wear every hat.
You're tired of paying every month for acuity 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 Swim teaching aids (kickboards, noodles).
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 swimming 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.

Revenue: $360 + $120 + $50 = $530. Pool rent: $140. Net: $390 for 4 hours. But a group class had 2 no-shows ($60 in lost revenue) and you couldn't fill those spots. Summer wait list has 40 families.

Why swimming instructors leave the big platforms
acuity: Scheduling only. Can't handle group class enrollment, pool time optimization, or seasonal waitlists.
wave: Free but can't manage class registration, package billing, or per-class profitability.

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 Wave'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 Wave'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 swimming instructors we can verify. For user testimony, read the independent reviews — Wave on G2 and on Capterra — where the reviewers are not selling you anything.
Check the price yourself:Wave'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 swimming 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 swimming 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, Wave $228/yr, Square — 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 $32,000 median we cite for the typical swimming 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.
Found something out of date? Prices change and we don't catch every move the day it happens. This guide is published and maintained by the Nexa team; if a figure here is wrong, tell us and we'll fix it — getting it right matters more to us than the sale.
FAQ
Is Nexa really a Wave replacement?
For solo swimming instructors and small teams, yes. invoicing, scheduling, CRM, time tracking, task management, and full accounting — all for $279 once. Wave may be better if you have a large team (10+) or need enterprise-specific features.
What does Wave do that Nexa doesn't?
Wave has features like Free plan covering unlimited invoices and bookkeeping and Bank transaction import on Pro that some businesses rely on. For most solo swimming instructors, these aren't dealbreakers.
How fast does Nexa pay for itself?
At $19/month, Nexa pays for itself in 14.7 months. After that: $228 saved every year.
Can I pay in installments?
Yes. Nexa is $279 as a one-time payment, or 3 payments of $99 ($297 total). Either way it's a one-time purchase — no subscription, no recurring fees ever.
