Priced per month, eBay listing tools run from $0 to $184.99. Priced the way it actually hits you — per listing — the same tools run from about three cents to a dollar fifty, and which end you land on depends almost entirely on how many things you list, not on which logo you picked. Below are the real numbers, read off five vendors’ own pricing pages on 29 July 2026, plus the arithmetic that turns a monthly price into a per-listing one. It is the calculation nobody selling AI eBay listing software puts on their pricing page, including us.
Four tags, four sizes, one box. The spread in this category is not about what the software does — it is about how the vendor decided to meter it.
The five pricing models, and what each one really charges for
Every tool in this market picks one of five ways to bill you, and which one you are looking at tells you more than the headline number does.
Flat subscription, unlimited listings. SixBit — a Windows desktop eBay lister shipping far longer than we have — runs $29.99, $49.99, $99.99, $139.99 and $184.99 across five editions with no per-item cap. Vendoo is $14.99 / $29.99 / $59.99 monthly ($12.49 / $24.99 / $49.99 billed yearly). List Perfectly is $29 / $49 / $69 / $99+. Easiest model to reason about; its only trap is charging the same in the month you list four things as in the month you list four hundred.
Metered by listing count. Crosslist: Bronze $29.99 for 200 new listings a month, Silver $34.99 for 500, Gold $39.99 for 1,000, Diamond $44.99 unlimited. Fifteen dollars separates cheapest from dearest and buys a five-fold cap increase — the tiers are packaging, not economics.
Metered by AI credits, separately from listings. The newest model, and where the money quietly moves. List Perfectly is unlimited on listings but capped on AI: 25 assistant uses a month on Simple, 50 on Business, 200 on Pro, 1,000+ on Pro Plus. Crosslist is franker — AI is a +$4.99/month add-on carrying 200 to 2,000 credits by tier. Do that division and you learn what the marketing does not say: a credit costs a quarter of a cent, and no frontier vision model writes a full, category-aware listing for that. Fine for a catalogued sneaker; not fine for an uncatalogued FANUC teach pendant.
Research subscriptions are a different budget line. ZIK Analytics is $39.90/month for Pro and $59.90 for Pro+ with a $1 trial, and it lists nothing for you — it competes with Terapeak, not with a lister. Sellers bolt it on and then call their “listing software cost” $70 a month. Keep the lines apart, or read our honest comparison of Terapeak alternatives.
Bring your own API key. The software is free; the AI is not, and you pay for it directly rather than through a vendor’s margin. That is what ING Listing Engine does, and it behaves least like the other four — which is the point of the two sections below.
The 2026 price table
Every figure below was read off the vendor’s own pricing page on 29 July 2026. Prices in this category move; check the date before you trust the number.
| Tool | Entry plan | Top plan | Listing cap | Free option |
|---|---|---|---|---|
| Vendoo | $14.99/mo | $59.99/mo | Unlimited on all paid tiers | Permanent free tier, 5 items/month; 14-day trial |
| List Perfectly | $29/mo | $99+/mo | Unlimited listings; AI capped at 25–1,000+/mo | 100-listing money-back guarantee |
| Crosslist | $29.99/mo | $44.99/mo | 200 → unlimited by tier | 3-day money-back, under 20 listings |
| SixBit | $29.99/mo | $184.99/mo | Unlimited on all editions | None advertised |
| ZIK Analytics (research) | $39.90/mo | $59.90/mo | Query caps by tier | $1 trial |
| ING Listing Engine | $0 (open beta) | $0 (open beta) | None | Free beta; you supply and pay for your own Claude API key |
Divide by listings, not by months
A monthly price is not a cost. The cost is what one finished listing takes out of your margin, and that number moves by a factor of fifty depending on your volume. Same subscriptions, three volumes:
| Plan | Per month | 20 listings | 100 listings | 500 listings |
|---|---|---|---|---|
| Vendoo Starter | $14.99 | $0.75 | $0.15 | $0.03 |
| List Perfectly Simple | $29.00 | $1.45 | $0.29 | $0.06 |
| Crosslist Bronze | $29.99 | $1.50 | $0.30 | capped at 200 |
| SixBit Home & Hobby | $29.99 | $1.50 | $0.30 | $0.06 |
| ING Listing Engine (API only) | $0 + usage | ≤ $0.25 | ≤ $0.25 | ≤ $0.25 |
Read the bottom row against the rest and you have the honest summary of this entire page. A subscription gets cheaper per listing the more you list. An API bill does not. Ours is flat, so it wins at the bottom of the table and loses at the top. Somewhere around 60 listings a month Vendoo’s $14.99 Starter plan costs less per listing than our ceiling does; against List Perfectly Simple and SixBit the crossover is nearer 120.
Where the ≤ $0.25 comes from
That number is a ceiling, not an average, and every input is checkable.
- The app generates listings with Claude Opus 4.8 (
claude-opus-4-8), and it caps each listing call at 8,192 output tokens. - Anthropic’s published rate for that model on 29 July 2026 is $5 per million input tokens and $25 per million output tokens.
- 8,192 × $25 ÷ 1,000,000 = $0.2048. That is the hard ceiling on the output half of one listing. The cap is in the code, so the model cannot run past it however long-winded it gets.
- The input side is one photo plus the prompt. Even allowing a generous 10,000 input tokens, 10,000 × $5 ÷ 1,000,000 = $0.05.
Add them and one listing cannot cost more than about $0.25 in tokens. In practice it will be a good deal less, because a finished eBay listing is nowhere near 8,192 tokens of output. We have not published a measured average, and we are not going to invent one — what we can stand behind is the ceiling and the arithmetic that produces it. If your real cost lands at $0.10, every crossover in the section above roughly doubles: 150 listings a month against Vendoo Starter, 290 against List Perfectly.
The closest like-for-like: List Perfectly Pro is $69/month with 200 AI listing-assistant uses. Ignore everything else that $69 buys and it is $0.345 per AI listing, above our ceiling. The fair reading is not “we’re cheaper” — it is that a metered-AI plan charges you a margin on the model and a bring-your-own-key tool charges you the model’s cost. Predictable bill, or smaller one.
What “free” means here, in four incompatible senses
Four vendors above advertise something free. Only one is software you can use indefinitely without paying.
- A permanent free tier with a hard cap. Vendoo’s free plan is genuinely free forever — at five items a month. If that is your volume, it is a complete answer and you can stop reading.
- A money-back window. Crosslist’s 3-day guarantee applies only under 20 listings, and an annual refund deducts $9.99. List Perfectly’s is a 100-listing guarantee. Refunds, not free tiers — you pay first.
- A paid trial. ZIK’s $1 trial is a dollar. Fine, but the word “free” is doing work in the marketing that it does not do in your bank account.
- Free software, paid AI. Ours. Nothing to pay us, no card taken, and a real bill from Anthropic that scales with your listing count. Calling that “free eBay listing software” without the second half of the sentence would be dishonest, which is why the second half is on this page.
What happens when the beta ends
No price has been announced, and we are not going to pretend otherwise. The app ships licence-activation plumbing, so it is fair to assume it will not be free forever — anyone telling you a free beta is a permanent commitment is guessing. Two things are firm: the beta takes no card, so nothing converts to a charge behind your back, and your API key is yours — your account, your billing, portable to any other tool that accepts one. That is the part of the spend a vendor cannot lock up.
When paying a subscription is the right call
Genuinely, and often. Four cases where the money is better spent elsewhere:
- You sell on more than one marketplace. Vendoo, List Perfectly and Crosslist post to eight to eleven of them. We are eBay-only — our cross-listing exporter writes files and posts nothing. If that is your bottleneck, $14.99 solves it and we do not; the feature-by-feature comparison with Vendoo scores the rows we lose.
- You list from a phone. Every tool above runs in a browser or an app. Ours is a Windows desktop application.
- You do not want to hold an API key. A real barrier, and worse UX than a checkout page. If pasting a key into a settings box is a hard no, buy a metered plan.
- You list at volume and only need listings created. Past a hundred-odd a month, a $14.99 flat plan beats a per-listing API bill. SixBit at $29.99 is the closest structural twin to what we build — Windows desktop, unlimited listings — and it has been doing that job for years longer. It is also the closest surviving thing to Turbo Lister, which is how most people meet it.
What none of them do is tell you what to charge. Every tool in the table creates listings; not one prices your item against real sold comps, which moves more money than listing speed does. That is the argument for the free beta, and the same argument behind the repricer that refuses to price below your cost. Download the Windows beta and the only bill you will see is the one from Anthropic.
Common questions
How much does AI eBay listing software cost in 2026?
$14.99 to $99 a month for the mainstream cross-listing tools, up to $184.99 for SixBit’s top desktop edition — all read from vendor pricing pages on 29 July 2026. Divided by volume that is roughly $0.03 to $1.50 a listing. A bring-your-own-key tool costs nothing monthly and prices per listing instead; for ING Listing Engine the ceiling is about $0.25 of Claude API usage.
Is there genuinely free eBay listing software?
Only with a cap or a catch. Vendoo’s free plan is permanent at five items a month. Crosslist and List Perfectly offer money-back windows, which means you pay first. ING Listing Engine is free during its open beta with no card, but you supply your own Claude API key and pay Anthropic for usage. eBay’s own listing tools are the other genuinely free option, and worth trying before you buy anything.
Why do some tools charge extra for AI?
Because every AI listing costs the vendor real money, so they cap it or bill it. List Perfectly caps AI uses at 25 to 1,000+ a month by tier; Crosslist sells AI as a +$4.99/month add-on with 200 to 2,000 credits. At $4.99 for 2,000 credits a credit is a quarter of a cent — a useful signal about how large the model behind it can be.
Is bring-your-own-API-key cheaper than a subscription?
Below roughly 60 listings a month, yes, often by a lot, because you pay only for what you generate. Above it a flat $14.99 plan wins and keeps winning as volume rises. The API bill is flat per listing; a subscription is not.
What will ING Listing Engine cost after the beta?
Unannounced. The app carries licence-activation code, so expect a paid tier eventually. The beta takes no payment details, and the Claude API key you set up stays yours and portable whatever happens to the software’s price.
