Verdict: SellerSonar vs sellerboard is listing monitoring vs profit analytics: according to its pricing table, sellerboard costs $19 a month ($15 billed yearly) and shows what each product earned after fees, ads and cost of goods, with PPC, inventory, a repricer and daily listing alerts on every plan. SellerSonar starts at $19.98 a month billed yearly and checks any ASIN, yours or a competitor’s, every 1 to 4 hours for new sellers, Buy Box changes and listing edits, with no Seller Central connection.
Best for: sellerboard for profit, PPC and inventory; SellerSonar for hijacker, Buy Box, listing and keyword rank alerts. Look elsewhere if: you want one suite for product research, listings and ads, which is closer to what Helium 10 sells.

We read sellerboard’s pricing table, feature pages, help center and changelog on November 4, 2026, and took the sellerboard screenshots below in its public demo account, which needs no registration.

Who each tool is for
Sellerboard is for sellers who want to know their real profit. It pulls orders, fees, ad spend and refunds from Seller Central and nets them against your cost of goods. It suits private label and wholesale sellers who make decisions product by product.
SellerSonar is for sellers who need to know when a listing changes. It suits brands that share listings with resellers, wholesalers who watch Buy Box rotation, and agencies that track ASINs they do not own, because it reads Amazon’s public pages and needs no account connection.
Where sellerboard wins: profit, PPC, inventory and repricing
Sellerboard is the stronger tool for everything about money after the sale. SellerSonar does none of these jobs.
Profit dashboard
According to sellerboard’s FAQ, its Profit Dashboard “combines fees, ads, refunds, VAT/GST, shipping costs, and COGS into one view”, with drill-down from account level to product and order level.
The tiles, labeled “Today”, “Yesterday”, “Month to date” and a month forecast, put net profit next to ad cost and payout. They answer the question “did this product make money?”, which SellerSonar does not try to answer.
PPC optimization
The sellerboard PPC page describes bid automation toward a target ACOS: sellerboard “calculates Break-even-ACOS and bid for each keyword”, and you approve its recommendations by hand or let it apply them on autopilot. It also harvests converting keywords and moves poor performers to negatives.
The useful part is profit next to ACOS. You see which campaign makes money after fees and cost of goods, not just which one sells.
Inventory planning
Sellerboard’s inventory planner recommends reorder timing and quantities from “historic sales and sales velocity”, seasonal trends and your supplier lead times. Purchase orders, FBA shipments and prep center stock sit in the same module, and the demo menu adds a Cashflow page.
For a seller who pays for stock months ahead, this is the second reason to buy sellerboard. SellerSonar’s stock alerts only report what Amazon shows on the listing, such as out of stock.
Repricer, added in 2026
Sellerboard launched its repricer on September 3, 2026, and its repricer page says it is “Included in every sellerboard plan.” It sets price floors from the cost of goods, fees, VAT and profit targets already in your account.
That changes the math for sellers who pay for a separate repricer. SellerSonar does not reprice: it tells you when a seller’s price or the Buy Box changes, and you decide what to do.
Review requests and money back
According to sellerboard’s pricing table, every plan sends automated review requests or follow-up emails (150 a month on Standard, 6,000 on Professional). Its money back tools find lost and damaged inventory to claim from Amazon. SellerSonar sends nothing to buyers.
💡 Expert Tip: If you pay for a repricer and sellerboard separately, compare the two before your next renewal. According to sellerboard’s repricer page, its repricer is included in every plan, from the $19 Standard plan up.
Where sellerboard stops: listing alerts
Sellerboard does sell listing alerts: its pricing table lists “Listing change alerts” on every plan. What matters is what they cover, how often they run and whose listings they can watch.
What the alerts cover
Sellerboard’s demo account lists 32 alert types across product, performance, financial, inventory and advertising groups. For listing protection, the relevant ones are title, text, main image, brand and category changes, “Listing closed”, “Number of sellers/SKU’s on a listing changed”, “Buy box lost” and “New lowest price offer”.
Three gaps stand out: there is no Buy Box won alert, the seller alert is about the number of sellers changing rather than a named new seller, and the price alert watches the lowest offer on your own listing, not a competitor’s product.
The alerts land in one list with a priority and a resolved checkbox. The “Buy box lost” rows say what happened, but not who took the Buy Box or at what price.
How often they run
Sellerboard’s help center answers this directly. Its alert settings guide says “Alerts are evaluated daily using the most recent data available from Amazon.”
A daily check is fine for fee changes, dimension changes and restock warnings. It is slow for a hijacker who undercuts you in the morning and holds the Buy Box until the next run.
Whose listings they watch
The alerts dashboard guide says alerts “are generated automatically based on Seller Central data”. So sellerboard needs your seller account connected, and it alerts on your own listings only.
Its keyword tools are the one place it looks at other sellers’ products. Keyword Research accepts a competitor’s ASIN and shows the keywords driving it, from Amazon Brand Analytics data, and it is “available for brand-registered sellers”.
Where SellerSonar wins: any listing, checked every few hours
SellerSonar does one job: it watches listings on Amazon’s public pages and alerts you when something changes. According to SellerSonar’s plans, it checks every 4 hours on Pro, every 2 hours on Premium and every hour on Business, on 23 Amazon marketplaces.
New sellers and Buy Box changes, by name
SellerSonar’s Buy Box and pricing alerts work by Seller ID. Seller appeared, Seller removed and Seller’s price changed are on every plan; Buy Box Won and Buy Box Lost, which show who took the Buy Box and at what price, start on Premium.
These five alerts are off by default in a new SellerSonar account, so switch them on in Alerts > Delivery Settings before you rely on them. The Buy Box Tracker, also from Premium, adds ownership share by seller over time.
In this feed from SellerSonar’s own account, Amazon cut its price on a Levoit air purifier from $69.97 to $45.48 on November 4, 2026. A seller sharing that listing sees the change on the next check and can decide whether to match it.
Competitor tracking on any marketplace
Sellerboard cannot add a competitor’s ASIN to its alerts. SellerSonar’s competitor monitoring tracks rivals’ prices, category ranks, reviews and listing quality on any marketplace, with or without linking them to your own products.
Per SellerSonar data from October 2026, the TW SHINE set in this view sold at $9.49 against a 7-day average of $9.99, a 5% cut. A profit dashboard never shows you that, because it is not your product.
Keyword tracking: research vs rank tracking
Sellerboard analyzes keywords; it does not track ranks. Its Search Term Performance report shows impressions, clicks and profit per search term from Brand Analytics for brand-registered sellers, and we found no organic rank tracker on its feature pages.
SellerSonar’s keyword tracking records the organic and sponsored position of each ASIN for each keyword once a day, for brand owners and resellers alike.
In this SellerSonar chart, the Duracell 28-pack moved between positions 8 and 11 for “aa batteries” while Amazon Basics held position 1. A Keyword position changed alert follows fixed rules, for example any move inside the top 10.
Share of Voice
Sellerboard’s Search Term Performance includes what it calls “share-of-voice insights”, built from your own Brand Analytics impressions and clicks. SellerSonar’s Share of Voice and Share of Shelf, on the Business plan, show your brand’s visibility across the keywords you track against competitors, with no Brand Registry needed.
Suppressed listings
Sellerboard’s “Listing closed” alert covers a closed listing. SellerSonar’s retail issue alerts also catch a listing that is live but hidden from search, or live with its Buy Box suppressed, and each issue comes with a dated snapshot of the product page.
Per SellerSonar’s event log, this amazon.es listing dropped out of search on October 21, came back on October 23 and was suppressed again less than five hours later. Each event is timestamped, so you know how long the listing was hidden.
🎯 Pro Insight: The two tools read different data. Sellerboard reads Seller Central, so it knows your fees, payouts and ad spend; SellerSonar reads the public listing, so it sees what shoppers see, including other sellers’ offers.
Pricing compared
The two tools price on different units: sellerboard by monthly orders, SellerSonar by tracked ASINs and keywords. These are the plans on sellerboard’s pricing table and SellerSonar’s plans page on November 4, 2026.
| Plan | Billed monthly | Billed yearly, per month | What the plan sets |
|---|---|---|---|
| sellerboard Standard | $19 | $15 ($179 a year) | 3,000 orders a month |
| sellerboard Professional | $29 | $23 ($279 a year) | 6,000 orders a month |
| sellerboard Business | $39 | $31 ($369 a year) | 15,000 orders a month |
| sellerboard Enterprise | $79 | $63 ($759 a year) | 50,000 orders a month |
| SellerSonar Pro | $23.98 | $19.98 | 150 ASINs, 500 keywords, every 4 hours |
| SellerSonar Premium | $47.98 | $39.98 | 300 ASINs, 2,000 keywords, every 2 hours |
| SellerSonar Business | $89.98 | $74.98 | 500 ASINs, 3,000 keywords, every hour |
Every sellerboard plan includes the same features, now including the repricer, so you choose by order volume. SellerSonar plans also differ in features: per SellerSonar’s plans page, Buy Box Won and Lost alerts start on Premium, and Share of Voice and webhooks on Business.
Both offer a free trial with no card: one month for sellerboard, and 14 days on SellerSonar with 5 ASINs and 10 keywords. Our sellerboard pricing guide covers its order limits, review-request caps and annual billing in detail.
Running both at entry level costs $34.98 a month billed yearly, sellerboard Standard at $15 plus SellerSonar Pro at $19.98, according to the two pricing pages. Billed month to month, it is $42.98.
Is SellerSonar a sellerboard alternative?
Only for the alerts. SellerSonar does no profit accounting, PPC management, inventory planning or repricing, so if you use sellerboard for any of those, SellerSonar replaces none of it.
If you bought sellerboard mainly for its listing alerts, SellerSonar is the closer fit: more frequent checks, Buy Box Won and Lost, named sellers, competitors and keyword ranks. Many sellers keep sellerboard for the numbers and add SellerSonar for the listings.
Which one should you choose?
Pick by the problem that costs you more: not knowing your margin, or not knowing what happened to a listing.
| You are | Choose | Why |
|---|---|---|
| New private label seller with a few products | sellerboard | Profit per product matters more than alerts until a listing is worth protecting |
| Brand that shares listings with resellers | Both | sellerboard for margin; SellerSonar’s Seller appeared and Buy Box alerts for who is on the listing |
| Wholesaler or reseller | Both | sellerboard’s Reseller Workflow and profit per batch; SellerSonar for Buy Box rotation during the day |
| Agency watching client or competitor ASINs | SellerSonar | No Seller Central connection per client, and competitors on any marketplace |
| Seller paying for a separate repricer | sellerboard | Its repricer is included in every plan |
| Brand tracking keyword ranks | SellerSonar | Daily organic and sponsored positions; sellerboard has no rank tracker |
📌 From Our Experience: When a hijacker joins a listing, a profit dashboard shows it later, as lost sales in the next day’s numbers. A seller alert shows it as a named seller and a price a few hours after it happens, while there is still time to match the price, report the seller or wait.
Final Expert Recommendations:
Keep or buy sellerboard if you need true profit per product, PPC automation, inventory planning or its included repricer, and size the plan by your peak monthly orders. Add SellerSonar when the risk sits on the listing itself: a new seller, a lost Buy Box, edited content, suppressed search or a slipping keyword rank, on your ASINs or a competitor’s. Start SellerSonar’s listing monitoring on your best sellers and switch on the Buy Box and pricing alerts first.
