Is Sidekick Tools the Best eBay Automation Tool?
eBay reselling is no longer a side hustle you can manage in your spare time. Today’s successful resellers operate like 24/7 businesses, responding to buyers, sending offers, and refreshing listings around the clock. Doing all of that manually becomes impossible once you try to scale.
That’s where eBay automation steps in. Sidekick Tools, formerly known as Posh Sidekick, has evolved far beyond its Poshmark roots. It now positions itself as a serious all-in-one automation app for resellers selling on eBay, Poshmark, Mercari, Etsy, and many others.
The big question is simple: Does Sidekick Tools really deliver on its “set it and forget it” promise for eBay? Let’s break it down.
What is Sidekick Tools aka Posh Sidekick?
At its core, Sidekick Tools (formerly Posh Sidekick) is a cloud-based reselling automation app + crosslisting app built for multi-platform resellers.
Instead of logging into eBay multiple times a day, the Sidekick Tools app handles repetitive tasks in the background. This allows resellers to focus on sourcing and growth instead of constant clicking.
One of the best eBay automation tools within the Sidekick Tools app is automated offers to buyers. When someone watches your listing, Sidekick Tools can send timed offers automatically, turning passive interest into real sales—even while you sleep.
Another key feature is smart relisting. By relisting items at optimal times, Sidekick Tools keeps your eBay listings “fresh,” which helps improve visibility in eBay’s search results.
Sidekick Tools also integrates AI-powered descriptions through its Magiscriptor feature. This tool generates clear, SEO-optimized product descriptions designed to rank better and convert faster.
Finally, crosslisting and auto-delist features help prevent double sales. When an item sells on one platform, it’s automatically removed everywhere else, which many sellers consider the holy grail of automation.
What Makes Sidekick Tools the Best eBay Automation Software?
One reason Sidekick Tools stands out is its human-like activity system. Actions are spaced naturally, which reduces the risk of triggering eBay’s automation flags. This makes it feel less like a bot and more like a real seller at work.
Another advantage is its mobile-first design. Unlike older tools such as 3Dsellers or InkFrog, Sidekick Tools is built for resellers who manage their business on the go. You can control automation from your phone without dealing with clunky dashboards.
In 2025, Sidekick Tools also introduced AI photo editing tools. These updates include instant background removal and studio-style enhancements, making eBay listings look professional without expensive photography setups.
Together, these features make the eBay automation app feel modern, flexible, and designed for today’s reseller—not yesterday’s power seller.
Sidekick Tools vs. Other eBay Automation Tools
Choosing the best eBay automation tool depends on your selling style. Below is a clear comparison using common “best eBay automation” search criteria.

Sidekick Tools eBay Automation: Pros vs Cons
Like any automation tool, Sidekick Tools isn’t perfect. However, its strengths clearly outweigh its limitations for most active sellers.
Pros:
- Sidekick Tools delivers massive time savings, often freeing up 15 or more hours per week.
- Its precise timing system avoids unnatural behavior flags.
- It also offers excellent cross-platform syncing with Etsy, Depop, Poshmark, Mercari, and more.
Cons:
- The rebrand from Posh Sidekick can confuse long-time users at first.
- Additionally, higher-tier plans may feel expensive for very small hobby sellers who only list occasionally.
Even with these drawbacks, most sellers find Sidekick Tools’ value quickly outweighs the cost.
Real Results: What Resellers Are Saying
Sidekick Tools user feedback paints a consistent picture. Sellers report smoother workflows, fewer missed offers, and more consistent daily sales once eBay automation is fully enabled.
Many users mention moving from 1–2 sales per day to 4–5 sales per day. This increase doesn’t come from magic—it comes from constant activity, timely offers, and fresh listings that automation makes possible.
The overall sentiment is clear: Sidekick Tools works best when used consistently, not occasionally.
Is Sidekick Tools the Best eBay Automation App?
Sidekick Tools is a strong “yes” if you want to automate tasks like relisting, crosslisting, and send offers to buyers on eBay. It’s especially valuable for resellers who rely on steady daily sales.
However, it may not be ideal if you’re a pure dropshipper, where AutoDS might be a better fit. Data-heavy researchers who live inside spreadsheets may also prefer ZIK Analytics.
Knowing your selling style makes the decision much easier.
