Does Wave Fit Used Electronics Sellers? Our Read
What used electronics sellers need from their software, from sources outside Wave and outside Nexa:
Sellers who buy used electronics from the public for resale may need a state or local secondhand-dealer licence. Rhode Island requires an Attorney General licence before buying tools or electronics from the public to resell. The statute lists video game consoles, MP3 players, computers, and audio and video equipment. The licence cannot be issued without a registered permanent place of business in the state. Software has to track which licence covers which purchases. (webserver.rilegislature.gov)
Per-unit records are a legal matter for secondhand dealers, since stolen-property holds attach to individual items. In Washington state, after a theft report the dealer must tag and safeguard the item and may not release it for 120 days without police consent or a court order. Police can renew a hold in 120-day periods. The dealer must give written notice 20 days before expiry, or the hold continues for another 120 days. The dealer therefore needs to find specific units and keep them from being sold. (lawfilesext.leg.wa.gov)
Accepting items whose manufacturer's serial number has been altered is prohibited. Washington law makes both altering a serial number on pledged property and accepting such property for secondhand purchase gross misdemeanors. Dealers need to record the serial number of each unit at intake. (lawfilesext.leg.wa.gov)
Sellers who take card or online-marketplace payments need to reconcile platform tax forms against their own books. The IRS says a third-party settlement organization files Form 1099-K only when gross payments to a payee exceed $20,000 and transactions exceed 200. That threshold was reinstated by the One, Big, Beautiful Bill. A seller whose own records of cost and sales are complete can match what the platform reports and explain any gap. (irs.gov)
Online sellers of used electronics record serial numbers before shipping, because buyers sometimes return a different, defective unit. An eBay Community poster advises photographing the serial-number tag in the listing. The serial number is usually unique to each unit, so the photo is evidence for a claim with eBay if a buyer swaps in another unit. This links each sale to a specific serial-numbered unit. (community.ebay.com)
Wave covers the money side of this trade reasonably well. Its bookkeeping, receipt capture and bank transaction import (on Pro, $19 a month) let a seller keep complete cost and sales records. That helps when matching a platform's 1099-K figures and explaining any gap. Wave does not cover what makes secondhand electronics different. Nothing in its feature list records a manufacturer's serial number at intake, ties a sale to a specific unit, or flags a unit so it can't be sold during a police hold. It also doesn't track which dealer licence covers which purchases. Those are legal matters for dealers, such as Washington's 120-day holds and the ban on accepting altered serial numbers, and for sellers who photograph a serial tag to defend a return claim.
Nexa has a similar profile. It offers expenses, bank reconciliation, profit and loss, sales tax tracking, 1099 summaries and receipt scanning, so it can support the same tax-matching job. Its only inventory feature is a simple stock count per product, and it says it has no full inventory management. Nothing in its feature list records serial numbers, finds a specific unit or blocks its sale. It also doesn't track licences, and it has no sync or import with QuickBooks or Xero, which would matter if you move records over from another system. Nexa is software you own and run yourself, with no hosted support desk or vendor-run onboarding.
Over three years Wave Pro costs $684 ($228 a year). Nexa is $279 once, or 3 payments of $99, and $458.64 if you add optional Cloud Sync for multi-device use. Nexa is cheaper, but price isn't the deciding factor here. If you already use Wave for books, keep it for that. If you resell used electronics bought from the public, the tool you most need is a per-unit inventory system for secondhand dealers, with serial capture at intake, holds on individual items and licence tracking. Moving between Wave and Nexa won't fill that gap.
Our read for used electronics sellers: Neither Wave nor Nexa records serial numbers per unit or holds a unit from sale, so a secondhand-dealer inventory system with serial-number intake is the tool this trade needs, whichever one handles your books.

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 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 used electronics sellers: Neither Wave nor Nexa is the main system for this work; start with software built for it. Nexa only makes sense beside it, at $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 financial suite and task manager 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?
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 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.
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 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.

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 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

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.
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.
Where the numbers come from

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.

FAQ
Is Nexa really a Wave replacement?
For solo used electronics sellers 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 used electronics sellers, 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.
