Wave vs Nexa The Real Comparison for Used Electronics Sellers
Wave
$19/mo ($228/yr)
VS
Nexa
$279 once — own forever
or 3 payments of $99
Break even: 14.7 months at Wave's current price.
Bottom Line
Wave costs used electronics sellers $228/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 14.7 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 used electronics sellers: Wave is solid software, but at $19/month it costs $684 over 3 years. Nexa does most of what Wave does for $279 once. For solo used electronics sellers 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 financial-suite, task-manager in one purchase 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
What Wave Actually Costs Used Electronics Sellers
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.
Where business tools fit — for a used electronics seller
Software doesn't do the actual work — it automates the business around it. And that part is the same for every used electronics seller: 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.

A lead, a call, a referral — and a quote or estimate that turns it into a booked job.

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 the actual work. (Nexa is built to be the one — but the honest options for each step are above and below.)

Sound Familiar?
Her bench is a graveyard and a hospital at once: a bin of devices bought as lots, some dead, some 'untested,' all needing the truth pulled out of them. She works through them with a multimeter and diagnostic software, checking every port, every button, the camera, the speakers, the battery's true health and not just whether it powers on, because the fastest way to a return is a tablet that charges but whose USB port is flaky. Data is the first ritual on anything that held someone's life: a full wipe, account sign-out, activation lock cleared, because reselling a device still tied to a stranger's account is both a dead sale and a privacy hazard. Refurbishing is parts and patience, a swollen battery replaced, a cracked glass swapped, contacts cleaned with isopropyl, the right cable and adapter matched so it ships complete. The clock is always running on value: the moment a new generation is announced, the model on her bench loses worth, so a phone that sits a week unsold can quietly depreciate past its margin. She prices against that decay, photographs the actual unit with its actual scuffs disclosed, and packs it anti-static and rigid, because an electronic that rattles in the box arrives DOA and disputed.
Fully testing every function so a 'working' device doesn't come back with a dead port or failing battery
Wiping personal data and accounts off used devices to avoid privacy liability and activation locks
Fast depreciation where a model's resale value drops the week a new generation launches
Sourcing replacement parts and stocking the right cables, batteries, and adapters to refurbish profitably
The books and job tracking are the pieces of that day. Some tools rent you each piece separately. A few — Nexa among them — bundle the lot into something you buy once. 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 This Means for Used Electronics Sellers
The median used electronics seller 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 used electronics sellers. You own it like you own your a multimeter and a set of precision and security-bit drivers.
Is Nexa actually right for a used electronics seller?
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 40,000 used electronics sellers 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 a multimeter and a set of precision and security-bit drivers.
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 used electronics sellers 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.
Used Electronics Sellers by the numbers — by place

A day in the life of a used electronics seller
Her bench is a graveyard and a hospital at once: a bin of devices bought as lots, some dead, some 'untested,' all needing the truth pulled out of them. She works through them with a multimeter and diagnostic software, checking every port, every button, the camera, the speakers, the battery's true health and not just whether it powers on, because the fastest way to a return is a tablet that charges but whose USB port is flaky.

Refurbishing is parts and patience, a swollen battery replaced, a cracked glass swapped, contacts cleaned with isopropyl, the right cable and adapter matched so it ships complete.

The tools a working used electronics seller actually owns
a multimeter and a set of precision and security-bit drivers
diagnostic and battery-health software for testing devices
anti-static mat, wrist strap, and a soldering/hot-air rework station
isopropyl alcohol, cleaning brushes, and replacement parts stock
anti-static bags and rigid padded packaging for shipping electronics
The tools of the trade — each a one-time buy that earns its keep for years.

You paid for these once because good tools last. That's the bar your software should clear too — priced like a tool you own, $279 once, not a subscription that costs more than your kit every year.
Where Nexa wins for a used electronics seller — and where it doesn't
The honest version. Nexa was built to beat the rented stack on the jobs that matter most to a used electronics seller — 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 jobThe usual rentalThe verdict
The whole connected stack3 subscriptions · ~$1,044/yrNexa wins big One tool, $279 once — Nexa follows each device from the bought-as-lot bin through testing, data wipe, and grading into the sale and your books as one record, so a working claim is backed by the test you ran and your margin against depreciation stays visible. without re-typing. That handoff is the part separate tools can't buy at any price.
Books & accountingQuickBooks →Nexa wins Because a model's resale value drops the week a new generation launches, Nexa keeps each device's purchase cost from the lot tied to its sale and your real margin, so you see profit before the depreciation clock runs out instead of reconciling later.
Job & project trackingJobber →Nexa wins Every port, button, and camera you check with the multimeter and diagnostic software becomes a record in Nexa, so a device you mark working can't ship with a dead port the buyer finds on their desk, because the full test result travels with the unit.
InvoicingFreshBooks →Nexa wins The function-test results and data-wipe confirmation you logged on the bench flow straight into the invoice, so the buyer gets an honest working description and you avoid a privacy-liability return without re-entering anything.

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 used electronics sellers we can verify. For user testimony, read the independent reviews — Wave 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 Wave itself. We list a tool when it is the honest pick for the job, not because of the payout.
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 used electronics seller'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 used electronics seller — 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.

Income contextThe $32,000 median we cite for the typical used electronics seller 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.
