Short answer
Epinium vs Sellozo: the short answer
Sellozo is a US Amazon PPC automation tool, owned since 2021 by the agency Netrush, for Seller Central brands and agencies. It charges a flat $250 a month for the first marketplace and $50 for each extra one, month to month, with no percentage of ad spend and a 30-day trial that needs a card. Its optimizer bids once a day toward a target ACoS per campaign, with AI dayparting, AutoPilot campaign building, a Buy Box repricer and a True Profit report. For ad automation alone on one or two marketplaces it costs less than Epinium, whose ads plan is Business at €349 plus 3% of managed spend. Pick Sellozo for cheap, hands-off PPC; pick Epinium for Vendor Central, approval before changes, an MCP and API your AI agents can write through, and listings, catalogue, stock and P&L in one European platform.

Choose Sellozo if…
You want ad automation at the lowest cost: $250 a month on one marketplace at any spend, against Epinium Business at €349 plus 3% of managed spend (about €1,100 at $25K). The higher your spend on one marketplace, the bigger the gap.
You want a longer look before paying: its free trial runs 30 days with the optimizer and AI dayparting on, though it needs a card. The Epinium paid-plan trial lasts 7 days.
You want a Buy Box repricer in the same tool, or you are an agency: agencies pay a flat fee per client, with volume discounts for large agencies. Leaving is easy with both: Sellozo is month to month with 24 hours' notice by email, and Epinium cancels from the platform any time before renewal.
Choose Epinium if…
You sell on Vendor Central, or on both: Epinium connects Seller and Vendor Central, and Sellozo documents only seller accounts.
You want to approve changes before they go live, or choose an autonomy mode, and to work from Claude or ChatGPT: Epinium's MCP and API read on every plan and write campaigns, listings and tasks on Business.
You need more than PPC: listings checked against Amazon's rules, catalogue, stock, a P&L to contribution margin and your own store, from a European company with data in the EU and an interface in five languages.
Advertising + listings (every Amazon field, checked against Amazon’s rules) + catalogue + stock + Profitability (P&L) in one platform, with your Shopify or WooCommerce store next to Amazon

We have not used Sellozo ourselves, so nothing below is our opinion: every point names the third party that reported it and links to it. Scores come from each product's own G2 page, read on the date shown — with the review count, because a high score on a handful of reviews is not the claim a slightly lower one on hundreds is.

Epinium
4.8/5
9 reviews on G2
A small sample: judge the score and the review count together.
For ad automation alone Sellozo costs less, and it adds a Buy Box repricer in the same tool. Epinium is a different purchase: Vendor Central, approval before changes, AI agents that can act on your account, and listings, catalogue, stock and P&L next to your ads, from a European company.
Approval First, or Autonomy
You choose: changes wait as tasks for your approval, or an autonomy mode (Maintenance, Growth, Expansion, Custom) applies them. New campaigns start paused, and every change is logged for 12 months with its old and new value, and can be undone. Sellozo's optimizer applies its bid changes itself and explains them in an activity log; to keep a bid you set by hand, you lock it.
Seller and Vendor Central
Epinium connects Seller Central (3P) and Vendor Central (1P), so a brand selling both ways runs them in one place. Sellozo's terms ask you to sign in with your Amazon seller account, and no current Sellozo page documents Vendor Central.
Your AI Agents Can Act
The Epinium MCP is in Claude and in the ChatGPT app directory, next to a public REST API. It reads on every plan and, on Business, writes campaigns, workflows, portfolios, tasks and listings. Sellozo documents no MCP or public API; its OzO chatbot, in beta since June 2025, answers questions about Amazon advertising and the app.
More Than PPC
Listings (every Amazon field, checked against Amazon's rules), catalogue, stock, Profitability and your Shopify or WooCommerce store sit next to your ads. Sellozo covers ads, a True Profit report and a Buy Box repricer, and its own fit page leaves creative and inventory management out.
European Data, GDPR-Native
Epinium is a Spanish company, independent since 2015, with data hosted in the EU (AWS Ireland) under GDPR and a data processing agreement. Sellozo's terms are under Delaware law, and its privacy policy does not mention GDPR or where data is stored.
Built for Amazon EU
Epinium is built in Spain for ES, IT, DE, FR and UK, with an interface in five languages and 23 Amazon ad marketplaces. Sellozo covers 20 marketplaces, eight of them in the EU and UK, from a US company with English content; its interface languages are not documented.
How the difference shows up
Beyond a bid optimizer:one place to run Amazon, under your control.
Sellozo moves your bids toward a target ACoS and leaves the rest of the account to you. Epinium works across ads, listings, catalogue and profit, with the control level you set: a review queue, or an autonomy mode.

Tasks to approve, or an autonomy modeEpinium manages Sponsored Products, Sponsored Brands and Display campaigns. Its changes wait as tasks for your approval, or an autonomy mode you switch on applies them. Sellozo has no approval step: its optimizer adjusts bids once a day toward the target ACoS of each campaign.
Your structure stays yoursEpinium works inside your campaign structure instead of rebuilding it, and when you leave, your campaigns stay in your account as they are. Sellozo also optimizes existing campaigns as they are, while AutoPilot and Campaign Studio add their own, named with a '(Sellozo AutoPilot)' prefix.
Every change on recordEvery change is logged for 12 months with its old and new value, and can be undone. Sellozo keeps a per-campaign activity log that shows each optimization and why it happened.

It is impossible to calculate the hours Epinium has saved me managing customer catalogs. I've modified catalogs of up to 3,500 SKUs and run SEO audits comfortably from the same panel.

Epinium's ability to analyze and adjust ads in real-time based on performance has enabled us to maximize ROI and achieve our business goals more effectively. Without a doubt, I recommend Epinium to any seller.

Try the Sellozo alternative that runs more than your bids.
For ad automation alone, yes. Sellozo charges $250 a month for the first marketplace and $50 for each extra one, with no percentage of ad spend. In Epinium, ads are run on Business, at €349 a month plus 3% of the ad spend its AI manages: about €1,100 a month at $25K. Guru (€159) gives you the platform but does not run ads. On one or two marketplaces Sellozo is cheaper at any spend, and the gap grows as spend grows. Epinium costs more because it also covers Vendor Central, listings, catalogue, stock, P&L and an MCP that writes.
Does Epinium do dayparting or hourly bids like Sellozo?
Yes. Epinium moves bids daily or by the hour, with Amazon Marketing Stream hourly data. Sellozo's optimizer runs once a day, and its AI dayparting works by the hour: when a campaign reaches 90% of its budget, it pauses it in its highest-ACoS hour, using 30 days of hourly data and Amazon Marketing Stream.
Does Sellozo work with Vendor Central?
Not documented. Sellozo's terms ask you to sign in with your Amazon seller account, and no current page describes Vendor Central. Netrush's 2021 release on the acquisition mentioned sellers and vendors, but nothing on Sellozo's site today confirms it. Epinium connects both Seller Central and Vendor Central.
How recently has Sellozo been updated?
Read on 7 November 2026: Sellozo's public release notes end in July 2025, after adding the OzO chatbot beta and editable Retail Ad Service campaigns in June 2025. The newest dated item on its site is a blog post of 30 September 2026. Its help-centre article on the free trial, from 2019, still says 14 days, while the site now offers 30. Trustpilot shows no new reviews in the last 12 months. Epinium's latest release is from 28 October 2026.
What does each contract ask of me?
Sellozo is month to month: you cancel by email to its support at least 24 hours before the new term, and payments are not refunded except at its discretion. Its 30-day trial requires a valid card. Epinium is monthly or annual and you cancel from the platform any time before renewal, effective at the end of the period; its 7-day trial of the paid plans needs no card and then leaves you on the free Brain plan.
What happens to my campaigns if I leave?
With Epinium your campaigns stay in your Amazon account as they are. Sellozo's terms say it makes changes until you cancel, and its campaigns also live in your Amazon account; what happens to a campaign that dayparting has paused at that moment is not documented, so it is worth checking that none is left paused when you cancel.
How much does Sellozo cost compared with Epinium?
Sellozo: $250/mo for the first marketplace, all features; +$50 per extra marketplace. Epinium publishes its pricing: Guru from €159/mo, Business €349 and Master €799 — published, not quoted on request. Business and Master also carry an advertising commission of 3% for new customers, charged only on the ad spend Epinium manages. You can start free with no credit card. Full detail on Epinium pricing. Competitor data verified on 7 November 2026 from public sources.
Is there a European alternative to Sellozo?
Yes: Epinium. Sellozo — US company founded in 2017 (Kansas City, per third parties); owned by the agency Netrush since October 2021. Epinium is a Spanish company, independent since 2015, with data hosted in the EU (AWS Ireland) under GDPR and a data processing agreement, built for Amazon EU (Spain, Italy, Germany, France and the UK) with the interface in five European languages and keyword suggestions per marketplace.
Does Sellozo optimise listings for Rufus and AI shopping assistants?
Not documented; its user guide covers no listing tools. Epinium generates and audits your listings with AI against Amazon’s rules, written for the shopper and for AI assistants like Rufus (GEO); see GEO / AI search. To be precise: Epinium writes for that surface, but it does not measure or score your visibility inside Rufus.
