SellerActive survived its 2022 acquisition better than most: it operates today as SellerActive by Cart.com (also sold as Cart Multichannel Management), month-to-month, with unlimited orders, listings, and channels at every tier, a genuinely fair structure. The meters moved to revenue instead: $99 monthly covers up to $10k in GMV, $209 to $25k, $349 to $100k, and the algorithmic repricer, a headline capability, costs $50 to $100 extra at every tier. Sellers shop for a SellerActive alternative when the GMV ladder starts climbing or the add-on math stops amusing them.
Quick comparison

|---|---|---|
| Pricing model | GMV tiers: $99 (to $10k), $209 (to $25k), $349 (to $100k), custom above (their pricing, Jul 2026) | $49/mo flat at any revenue |
| Repricing | Paid add-on: +$50/$75/$100 by tier | Rule-based per-channel pricing included on Plus and above |
| Orders/listings/channels | Unlimited - fair | Unlimited - same |
| Sync (their words) | “Real-time inventory visibility”; no numeric interval documented | Under 3 seconds, verifiable |
| Channels | Amazon, Walmart, eBay, Etsy, TikTok Shop + Shopify/BigCommerce/Magento | Amazon, eBay, Etsy + Shopify, WooCommerce, OpenCart |
| Branding/roadmap | Dual identity (SellerActive vs Cart.com console) | One product |
What SellerActive gets right
Unlimited everything at the entry tier is the structure this category should have shipped years ago, and month-to-month with no revenue share keeps the exit door honest. For a seller under $10k monthly GMV who wants Walmart plus TikTok Shop coverage, $99 is a defensible spend, and the Cart.com backing means the product is maintained, not orphaned.
The three frictions
The GMV ladder is a success tax. Crossing $10k in monthly sales, a normal growth moment, doubles the bill; crossing $25k adds two-thirds again, the pricing-shape pattern where the software’s cost tracks your revenue instead of its own. Flat pricing exists because the sync does not get harder when you sell more.
Repricing as an add-on. Per-channel price control is core multichannel operations, the base-plus-markup model, and pricing it separately at every tier reads as unbundling the point. Rule-based channel pricing (markups, floors) ships included with us; algorithmic Buy-Box chasing is a different, narrower product, where automation helps and where it burns.
“Real-time” without a number. The claim is the category default; the absence of a documented interval means nothing to hold it to, ask the three questions, then stopwatch it.
What Unifystock does instead
Pricing that ignores your GMV entirely: plans start at $49/month for two channels with second-level sync, buffers and one order queue, while per-channel rules, forecasting and the audit log sit on the plans above. Whatever the tier, orders and listings are never metered. Honest boundaries: Walmart and TikTok Shop are not in the native launch set; if either is core revenue, SellerActive’s coverage argument is real today.
Common questions
Is GMV pricing unfair?
Not unfair, directional: it bets you will grow into higher tiers. Decide whether you want your tooling betting on that with your money, the twelve-month total settles it per seller.
Which branding do I actually buy - SellerActive or Cart.com?
Functionally the same product family; operationally, dual identities can blur support and roadmap ownership. Ask where tickets land and which console is canonical before committing.
Do I need algorithmic repricing at all?
Rule-based pricing with floors covers most small-seller needs; algorithmic repricing earns its cost in Buy-Box-contested commodity categories specifically, the automation guide draws the line.
What does switching involve?
The standard afternoon: clean SKUs, connect, match, rules, verify.
Flat, with the operations included
No GMV ladder, no add-on meters, seconds of latency, from $49/month with unlimited orders. See pricing.
