Acuity Scheduling costs aquarium designers $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 aquarium designers: 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 aquarium designers and small teams, Nexa is the better deal.
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.
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.

✓ and ✗ for Acuity Scheduling come from its own published feature list. — means the feature isn't in that list, which is not the same as Acuity Scheduling lacking it: check with them. Three years is at today's price.
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.
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.
Software doesn't do your clients — it automates the business around it. And that part is the same for every aquarium designer: 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.
A new client finds you and books a time — no phone tag, no double-booking.
The session itself — with the client history, notes, packages, and add-ons right there instead of in three different places.
The work becomes the invoice — the hours, the add-ons, the materials, the deposit credited — totaled and sent, instead of re-typed at 9pm.
Paid by card or link, the deposit credited, and what's overdue chased — without you doing it by hand.
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.)
This is the connection that makes the rest worth it. A aquarium designer'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.
You didn't write this invoice — the job did.

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.
The median Aquarium Designer earns $32,000/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 aquarium designers. You own it like you own your Acrylic and glass fabrication tools for building and bonding custom tanks.
An honest fit check — because the wrong tool is worse than no tool.
The honest fit: if you're a solo or small aquarium designers 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.

Half the job is build and half is keeping things alive. A design day starts at a client's home or lobby, measuring the wall, checking whether the floor can carry a 300-gallon tank full of water and rock, and sketching how the sump and plumbing will hide in the cabinet below. Back at the shop you fabricate or fit the tank, rig the filtration, the skimmer, the return pumps, and the controller that'll text you if a parameter drifts. Install day is heavy and precise: leveling a tank that can't ever be moved once it's full, running RO water, aquascaping live rock and substrate into something that looks natural. Then comes the part clients hate, the wait, because a new system has to cycle for weeks before fish can survive in it, and you're the one explaining that no, we can't stock it tomorrow. The rest of the week is service routes: testing water, scraping algae, dosing, swapping filter media, and quietly catching the small failures before they become a tank crash. A dead pump overnight can kill a reef worth more than a used car, so the unglamorous maintenance is really the whole business.

The tools of the trade — each a one-time buy that earns its keep for years.
Here's the bar that matters: you spent $990–$4,220 on tools that last for years, and never thought twice. So why should the software cost more than your whole kit — every single year? Hold it to the same standard as a good tool: $279, once.
The honest version. Nexa was built to beat the rented stack on the jobs that matter most to an aquarium designer — 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.)
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.
On the work an aquarium designer actually lives in — scheduling & booking, crm & clients and invoicing — Nexa holds its own against the usual rentals (Calendly →, HubSpot →, FreshBooks →). Head-to-head on any single one it's competitive; what tips it is the thing none of them can copy: From the wall-and-floor measure through the build and the weeks of cycling to stocking and maintenance, each tank stays on one record so the system you design becomes the invoice without re-keying the scope between separate tools. in one record, no re-typing between four apps. One tool, $279 once, against 3 subscriptions · ~$900/yr. Concretely: on scheduling & booking, The on-site wall-measure and floor-load check, the weeks of cycling before a single fish goes in, and the stocking date sit on one calendar tied to the build, so a 300-gallon living-room job is scheduled as the record it bills from rather than split across tools.
Where it's not the answer: if you run real payroll for a team (use Gusto →), or run big email campaigns & automations (use ConvertKit →). Those tools are better at their one thing, and we'd rather point you to them than pretend.

We build an aquarium designer'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 an aquarium designer — 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.
