Whether you call it payment tracking, a platform for jobs, or a invoicing system — most aquarium designers in Cary mix and match Acuity Scheduling, Square, Vagaro, Wave along with other platforms. That's $636/year on recurring software. Within 5 years at today's prices, those subscriptions total $3,180.

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.
That is the work Nexa is built around: the job, the client, the hours and the invoice live in one place, so the paperwork side of the day doesn't need a second shift.
Every one of those was bought once and earns its keep for years. Nexa is priced the same way: $279 once, and it keeps working whether business is busy or slow.

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.
Found something out of date?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.
