The real difference between these two isn’t features, both are solid rule-based Amazon repricers with real-time capability, floor price protection, and genuine human support. It’s how they charge. Sellery takes 1% of your gross monthly sales, uncapped in principle, capped at $2,000/month in practice. Repricer Express prices by SKU count and update speed instead, so your bill doesn’t move just because your revenue does. Which one is cheaper depends entirely on your ratio of SKUs to revenue, not on which tool is “better.”
The real difference
Sellery, built by SellerEngine, is a real-time, rule-based Amazon repricer with 20 years of company history behind it. It reacts to competitor price changes as they happen rather than on a batch schedule, calculates a dynamic minimum price from your product cost and fees so you don’t sell at a loss, and includes private-label tools like sales-velocity pricing and Smart Lists for grouping items.
RepricerExpress covers the same core job, real-time monitoring, floor and ceiling protection, competitor filtering, but structures both its plans and its pricing around SKU count and channel count rather than revenue. That structural difference is what actually separates these two tools, more than any single feature does.
Speed comparison
Sellery markets itself as real-time across the board: it reacts as soon as a competitor’s price changes rather than waiting for a scheduled batch update, and this speed isn’t tiered by plan on its pricing page.
RepricerExpress ties speed to plan: hourly updates on the Express tier, 10-minute or instant on Plus, and instant on Expert. If you’re comparing entry-level plans specifically, Sellery’s real-time claim on its lowest tier is faster on paper than RepricerExpress’s hourly Express tier, so sellers who need instant repricing from day one but are still on a small catalog should weigh that directly rather than assuming price tier equals speed tier the same way across both tools.

Pricing: two real scenarios
Sellery’s cost scales with revenue, not catalog size, which cuts both ways depending on your business.
Scenario one: high revenue, few SKUs. A seller doing $200,000 a month across a tight catalog of 300 SKUs pays Sellery roughly $2,000 a month, the fee’s practical ceiling, regardless of how few listings they’re actually repricing. A SKU-based structure like RepricerExpress’s would size that same seller into a lower tier based on catalog count rather than revenue, since 300 SKUs is a small catalog by any plan’s standard.
Scenario two: high SKU count, modest revenue. A seller with 10,000 SKUs doing $20,000 a month pays Sellery about $200, since the fee tracks revenue, not listing count. That’s genuinely cheap for a large catalog, and it’s the scenario where Sellery’s model has a real structural advantage over a SKU-tiered tool: a big catalog with thin per-unit revenue costs less to reprice under a revenue-based fee than under one priced by SKU volume.
The honest takeaway: Sellery tends to win on cost for large catalogs with modest revenue. RepricerExpress tends to win on cost for high-revenue, smaller catalogs, and it’s the only one of the two with eBay coverage regardless of either scenario.
FAQ
Which is cheaper, RepricerExpress or Sellery? It depends on your catalog size relative to revenue. Sellery’s 1% of gross monthly sales tends to be cheaper for large catalogs with modest revenue; a SKU-based structure like RepricerExpress’s tends to be cheaper for smaller catalogs generating higher revenue per listing.
Does Sellery support eBay? No. Sellery’s published marketplace coverage is Amazon only, across eight country marketplaces.
Is Sellery real-time on every plan? Sellery’s site describes real-time repricing without a tiered speed structure by plan. RepricerExpress ties update speed to plan tier, with instant updates starting on the Plus plan.
Does RepricerExpress have a revenue cap like Sellery’s fee ceiling? RepricerExpress’s Express plan carries a monthly revenue cap as part of its plan structure, but pricing itself is based on SKU count and speed, not a percentage of revenue the way Sellery’s is.
Which one is better for private label sellers? Sellery publishes named private-label tools, including sales-velocity pricing and multi-ASIN competitor grouping. RepricerExpress didn’t have an equivalent named private-label feature set published at the time of writing.
Can I switch from Sellery to RepricerExpress without losing my rule history? Rule logic doesn’t transfer automatically between any two repricing platforms; you’ll need to rebuild your min/max and competitor filter rules in the new system, though RepricerExpress’s free managed setup is built to help with exactly that kind of migration.
