SellerApex is free up to 25 SKUs with no credit card and $49/month flat for unlimited SKUs, all 13 Amazon marketplaces, the AI Listing Optimizer, the AI PPC generator and the AI Amazon COO — so most small and mid-size sellers pay less and get the automation ChannelEngine leaves to you.
What are the biggest complaints about ChannelEngine?
It optimises product feeds, not Amazon listing compliance. Rejected SKUs, GTIN problems, wrong product types and missing required attributes are handed back to your team, and onboarding is a multi-week implementation project with enterprise pricing. SellerApex was built specifically to remove that friction: Setup in under 60 seconds with 1-click Shopify and Amazon OAuth instead of an implementation project.
Why are my Amazon listings still Inactive after using ChannelEngine?
Because tools like ChannelEngine move data; Amazon still rejects SKUs for missing UPC/EAN/GTIN, wrong product type, missing mandatory attributes, image policy violations, duplicate ASINs or missing compliance documents. SellerApex validates every SKU against Amazon's live product-type schema before submission, auto-fixes what it can, requests GTIN exemption where eligible, matches existing ASINs instead of creating duplicates, retries failures and reports per SKU in plain English why anything remains Inactive.

How do I migrate from ChannelEngine to SellerApex?
Sign up free, connect Shopify (or WooCommerce, Wix, BigCommerce, Etsy, eBay, Walmart) with 1-click OAuth, connect Amazon with 1-click OAuth, then press Sync All. Setup takes under 60 seconds, there is no CSV export from ChannelEngine, and existing Amazon listings are matched by SKU/ASIN rather than duplicated. You can keep ChannelEngine running in parallel while you compare results.
Does ChannelEngine have AI listing optimization or an AI agent?
No. ChannelEngine does not rewrite titles, bullets and backend keywords to Amazon's A9 rules, and it does not run an agent over your account. SellerApex includes an AI Listing Optimizer, an AI PPC campaign generator, and an AI Amazon COO that reads the connected account daily, finds Buy Box losses, rank drops, pricing and inventory issues, prices the damage in USD and returns one-click fixes.
Which marketplaces and store platforms does SellerApex support compared to ChannelEngine?
SellerApex supports 13 Amazon marketplaces (US, CA, MX, UK, DE, FR, IT, ES, NL, SE, PL, JP, AU) and source catalogs from Shopify, WooCommerce, Wix, BigCommerce, Etsy, eBay and Walmart, with two-way inventory and price sync, repricing rules, promotions and fulfilment routing. Coverage with ChannelEngine: true.
Can I list Shopify products on Amazon without a UPC or GTIN?
Yes with SellerApex: it detects GTIN-less SKUs, prepares the Amazon GTIN exemption path for brand-registered sellers and submits with the correct product-type schema. This is the single most common reason bulk transfers made with ChannelEngine and similar tools leave listings Inactive.
Is SellerApex an official Amazon app?
Yes — SellerApex is approved and listed in the Amazon Appstore as a public Amazon Selling Partner API (SP-API) application, so the Amazon connection is 1-click OAuth with no developer keys or token pasting.
