SellHelmSteer Your GrowthSee what a product actually earns. Then act on it.
Your campaigns are run by rules, not a black box: every change comes with the reasoning, numbers included. A flat monthly fee, not a percentage of your ad spend.
Free seller tools. Campaign Manager 99 USD/mo.
What you get from day one
The three tools every account gets: Free
Free
Profit
“I see my revenue every day. I find out my profit once a month, in a spreadsheet.”
Net margin, not revenue: your orders and fees next to your own cost of goods and expenses.
Your best-selling product is not necessarily your most profitable one. This is where you find out which is. Costs load in bulk from an XLSX template — no row-by-row typing.

Inventory
“I reorder when it feels low — and I have paid for that feeling in both directions.”
Stock levels and sales velocity in one view, so a restock decision is a reading rather than a guess.
It does not warn you when you run out, but while you still have time to order. A reorder planner turns a cover target into an order list with XLSX export, FBA age shows where money sits in old stock, and variation families group automatically.

Review requests
“I know I should ask every buyer for a review. I never do it consistently.”
Amazon-compliant review requests, sent on your own schedule.
Amazon’s own request goes out on your schedule. Once per order, by the rules.

Everything the Campaign Manager plan runs for you — by the playbook, by the numbers.
The rules come from the playbook. SellHelm runs them by the numbers.
A proven rule set steers the whole ramp-up — all it needs from you is your data. No black box: every change comes with the reasoning, numbers included.
ACoS persistently above its target, on a click sample that is large enough to mean something → bid down
Bid 0.85 → 0.68 (−20%)
Why: this product runs well above its target ACoS — spend is scaling faster than sales. The full numbers behind the decision are visible in your dashboard.
Built to help you get going on Amazon — and the control stays with you: approve every change yourself, or decide what SellHelm may apply on its own.
74 parameters behind every decision
Campaign performance, search-term behaviour, computed metrics, product economics, brand analytics and guard rails — weighed together before a single change is suggested.
Approval-based, semi-automatic or fully automatic — your call
Every suggested change is queued for you with its rule and its numbers — nothing touches your campaigns until you approve it.
You pick which rules SellHelm may apply on its own — those run by themselves, everything else still waits for your approval.
The whole rule set executes on its own within your bounds — and logs every change it made, with the reasoning, numbers included.
Every change logged — the reasoning and the numbers stay visible
Switch between modes at any time, even per rule — from the day Campaign Manager goes live.
How SellHelm grows your sales
Your product
Start from your live listing.
Collect keywords
We gather every relevant search term your customers use.
Add the winners
Promote the keywords that convert; cut the wasters.
Spend concentrates
Budget keeps moving toward the terms that convert, and away from the ones that do not.
Campaign System Builder
Give it the product, the daily budget and the phase — it draws the launch-ready campaign structure the playbook would build: auto, research and winner campaigns wired together, ready to create in one step.
It does not create empty campaigns, it creates a structure: which campaign discovers, which one tests, and which one carries the terms that already proved themselves. The same build you would do by hand, minus the three hours.
Keyword Harvester
Your buyers already tell you which search terms convert. The harvester promotes the winners into their own keywords and negates the wasters, so spend keeps flowing toward what actually sells.
Smart Alerts
A warning when advertising burns low stock, when sales pace breaks, or when a campaign stalls — before the month-end report would show it.
Full campaign control
Everything you would otherwise click through Seller Central, in one place — every change confirm-gated and logged.
Bids, budgets, pause/enable — campaign, ad group and keyword level
Search terms: what buyers actually typed, one-click harvest or negative
Product & category targeting with a searchable category tree
Negative keywords: live list, add and remove
Dayparting: a 24-hour schedule in your marketplace timezone
Keyword database: every keyword with 30-day numbers, XLSX/CSV export
Brands level: brand campaigns and products under each brand
Drill-down analytics: account → product → campaign → keyword
Simple, transparent pricing

Would you rather we ran it for you?
We also manage Amazon accounts hands-on — campaigns, listings and inventory — for a small number of sellers. Scope and price are agreed per account, so there is no plan to pick.
Free plan: up to 500 products, 5 connected Amazon accounts (one per merchant ID) and 1 user — no extra seats. Campaign Manager: up to 2,000 products in total across all your connected accounts (custom pricing above) and any number of connected Amazon accounts, with one extra user included beyond the account owner; every further user seat is 20 USD / month, added right on the surface. A product means a parent product — variations count as one.
Prices are per seller account, billed monthly, cancel anytime. Detailed plans are shown in the app after sign-up.

Frequently asked questions
What does SellHelm see in my account — and what does it not?+
Only what you authorize at the Amazon connect: it reads order, fee, inventory and advertising data. It never sees your login, has no access to your Seller Central account, and you can revoke the authorization at any time.
How do I connect my Amazon account, and is it reversible?+
Through Amazon’s own Login with Amazon flow, a few clicks. The authorization can be revoked any time in your Amazon account settings, and we delete your data on request.
What is included with every account?+
Profit calculation (orders, fees, net margin), inventory management with reorder guidance, cost management and review requests — free, no card required, up to 500 products and 5 connected Amazon accounts (a product means a parent product; variations count as one).
What does the 99 USD Campaign Manager add?+
Campaign analytics across all your marketplaces, keyword-level rule-based campaign management and the PPC Structure Generator, up to 2,000 products (custom pricing above).
I am a Skool member — how do I activate it?+
Your membership includes Campaign Manager while it is active: redeem the one-time code from the community classroom on the Billing page, no card needed.
Can I cancel, and what happens to my data?+
Any time. The Amazon authorization is revocable on Amazon’s side too, and we delete your data on request.
Which marketplaces and languages are supported?+
Amazon EU and North America marketplaces. The interface is complete in English and Hungarian; Slovak, Czech, Polish and Romanian are in progress, with further EU languages planned.
Is there a free trial?+
No. The seller tools are free in every account, permanently and without a card, so you can see your own numbers before you pay anything. For the Campaign Manager we do something different: the annual plan comes with a 14-day money-back guarantee.
How does the money-back guarantee work?+
Annual plans only. Within 14 days of your first annual payment, email [email protected] and we refund the full amount, no questions asked. One refund per customer. Your Campaign Manager access ends with the refund; your free seller tools stay exactly as they are.
