SellerApp vs Helium 10: the comparison with the fee included

They are not selling the same thing

Feature grids for these two produce a near-tie, which is a good sign that the grid is measuring the wrong thing. The companies are shaped differently.

Helium 10 is a research suite with advertising attached. Its centre of gravity is keyword and product discovery, and its reverse-ASIN work is the reference standard that other tools benchmark against — we say that as competitors, because it is true. It also carries genuine breadth beyond Amazon into Walmart and TikTok Shop, ships a data connector for AI tools, and bundles substantial education that is otherwise sold separately.

SellerApp is a seller platform with services attached. Its strongest software work is keyword discovery and listing quality scoring, it covers multiple marketplaces, and — the part almost no comparison mentions — it also sells managed advertising and publishes an agency rate. It has a permanent free plan requiring no card, which is rarer than it sounds.

So the honest first question is not which is better. It is whether you are buying research, software, or somebody's time. All three are on offer between these two companies, at very different prices.

The three facts every comparison leaves out

We read what currently ranks for this query. These three points were absent from all of it, and each of them can change the answer.

1. Helium 10's advertising sits on the Diamond plan. Their pricing FAQ states that Helium 10 Ads is available in Diamond plans. Several ranking comparisons imply PPC automation is reachable from the entry tier. It is not, so the real entry cost for running ads on Helium 10 is the Diamond price, not the Platinum one.

2. There is a 2% management fee on managed ad spend. Their pricing FAQ states plainly that Diamond plan customers incur a 2% management fee on PPC spend managed through Helium 10 Ads. It sits in the FAQ rather than on the plan card and is not asterisked against the plan price, so a buyer reading only the pricing table will not encounter it. We searched their page for a spend threshold on that fee and found none published — do not assume one exists.

3. SellerApp's service ladder is invisible in these comparisons. Their managed advertising plan starts at $750 a month, listing work starts at $200 per parent ASIN, and their agency rate is published as a starting $300 plus a band of 0.5% to 2.5% of Amazon ad spend. That is the entire services half of the company, absent from every head-to-head we found.

None of this is a criticism of either vendor. Both publish these facts on their own sites. It is a criticism of how the comparison gets written.

The numbers, with the billing tab named

Read from each vendor's own pricing page on 20 August 2026. The billing basis is stated because that is where most published figures go wrong.

Helium 10. Platinum is $129 a month on the pay-monthly tab and $99 a month on the pay-yearly tab. Diamond is $359 a month on pay-monthly and $279 a month on pay-yearly. Enterprise starts at $1,499 a month billed annually. A free plan exists with limited access. There is no Starter plan and no lower entry tier — any comparison quoting a much cheaper Helium 10 entry price is quoting a plan that is not on the page.

SellerApp. Freemium is $0 with no card. Pro starts with $99 a month. The Smart plan with automation is $250 a month, displayed against $149 with a footnote stating the discount covers the first three months. Custom is quoted. There is no monthly-versus-annual toggle on their page — every figure is monthly — and while their FAQ describes a 50% annual saving, no annual figures are published. The plan names sometimes quoted elsewhere are no longer on the page.

The reusable discipline, which we apply to our own page too: check which billing tab you are reading, name it when you quote a figure, and record the date. Two of the four prices above differ by more than 25% depending on which tab is selected.

Where the answer flips

Now the arithmetic, which is the part worth your attention.

At modest ad spend, the subscriptions dominate the comparison and the 2% is a rounding error. Helium 10 Diamond on the annual tab is the more expensive subscription, and if research is a real part of your week it is comfortably worth the difference.

At serious ad spend, the percentage becomes the price. At $50,000 a month in managed ad spend, 2% is $1,000 a month, which is roughly four times the Diamond subscription itself. The subscription comparison that every article runs is measuring the smaller number.

This is not an argument against percentage pricing — we charge one. It is an argument for two things. Cap it, so that a growing budget does not silently become a growing fee with no ceiling. And print it, so a buyer can model the year without a call. Where competitors are ahead of us on transparency we will say so; on this specific point we think a printed, capped rate is the better practice, and it is what we publish.

The calculator above will find your own crossover. Note that the SellerApp managed row and the Dr. PPC row are the like-for-like pair — both are somebody doing the work — while the subscription rows are the like-for-like pair with Orbit.

The question neither subscription answers

Both platforms give you better instruments. Neither gives you the hours or the judgement to use them, and that is usually the binding constraint.

Across the 47 brands we manage — 3,086,624 search terms that took a click, Amazon search data from 1 May 2026 onward — 48.5% of every dollar of search spend went to terms that produced zero orders: $4,962,963 of $10,243,379, while 0.9% of 891,585 terms drove 80% of all sales.

Both tools on this page can show you a search-term report. Neither will sit down and work through a tail that runs to tens of thousands of entries per account, and neither will tell you that your problem is concentration rather than efficiency. That is a reading job, and whether you buy it as software or as a service is the actual decision on this page.

You can run the test yourself before you buy anything: export your search-term report, filter to spend with zero orders, and see what share of your budget is sitting there.

Where Orbit and Dr. PPC sit

If you are comparing software, compare Orbit, not Dr. PPC. Orbit covers sales and advertising analytics, search-term and campaign profitability, keyword and traffic tracking, inventory, finance, ASIN profitability, and the BSR, buy box, price and fee trackers, and it is included with Dr. PPC at no additional charge. Comparing a managed service to a self-serve subscription on price alone is how buyers end up disappointed with both.

Dr. PPC is the managed tier. Fable 5 reads the whole ad account, writes a strategy per product against that brand's real economics, then proposes each change with the evidence behind it, a measurement plan and a rollback trigger. You pick the autonomy level, from approving every change to fully autonomous inside agreed guardrails, and inventory risk, pricing, launches and creative always come back to a human. It is $300 a month plus 3% of ad spend, capped, month-to-month, with the first 30 days free, from Full Circle — a full-service Amazon management company with more than $500M in managed revenue across 100+ brands.

Where each of the others is the better buy: Helium 10 if discovery is the bottleneck and you want one suite for research, listings and ads. SellerApp if you want a permanent free tier with no card, or a flat managed fee rather than a percentage. And if the thing eating your margin is stockouts, storage and fee leakage rather than bidding, Dr. Stock is the honest redirect — no plan on this page will touch it.
