Comparison
Price Guard is a capable repricing toolkit, but its breadth can bury the feature that matters most: never selling below cost. Undercut flips that priority. The per-item hard floor is not a buried setting — it is the starting point for every repricing decision. Set your floor first, then let Undercut beat the lowest live competitor automatically. No credit card to start, no complex onboarding. Just floor-first repricing at a price most eBay sellers can afford from day one.
| Feature | Undercut | Price Guard |
|---|---|---|
| Per-item hard floor | Core feature — set a unique floor on every listing before any rule fires | Supported |
| Free entry tier (no card) | Free plan: 25 listings, no credit card ever required | Varies — check current pricing page |
| Starting paid price | $29/mo for 100 listings | Varies — typically higher entry cost for comparable listing counts |
| Reprice frequency (fastest tier) | 15 minutes on Pro and Scale | Varies by plan |
| Platform focus | eBay-only, purpose-built repricing | Broader multi-channel toolkit beyond repricing |
| AI aggressiveness tuning | Available on Pro and Scale ($79/mo) | Supported |

Most repricers treat margin protection as an afterthought — a minimum-price field buried in advanced settings. Undercut treats the hard floor as the foundation every rule is built on. Before Undercut ever adjusts a price, it checks whether the resulting price clears that item's floor. If it does not, the listing stays put. This means a floor misconfiguration cannot cascade into a loss-making sale.
Knowing what to enter as your floor is as important as having one. Take a typical electronics accessory: cost of goods $8.00, outbound shipping $4.00, eBay final value fee 13.25% of sale price, and a minimum acceptable margin of 15%. Solving for floor price P where P × (1 − 0.1325) − $12.00 ≥ 0.15 × P gives P ≥ $16.72. Enter $16.72 as your hard floor in Undercut for that listing. No matter how aggressively competitors drop, Undercut will not touch that listing below $16.72. The same logic applies to any category — swap in your actual fees, shipping, and margin target. Undercut's eBay profit calculator (linked below) can walk through the arithmetic for you.
The comparison table below covers the dimensions that matter most to eBay sellers weighing these two tools. Where Undercut lacks data on a Price Guard capability, we note 'Supported' or 'Varies' rather than invent a weakness.
Undercut's four tiers are sized for real eBay seller stages — from someone testing the tool on 25 listings to a high-volume operation repricing 10,000 SKUs with priority support.
An honest comparison includes candor about fit. Price Guard is a broader repricing and listing management platform. If your workflow depends on features beyond eBay repricing — such as cross-channel inventory sync or integrated listing creation tools — Price Guard's wider toolkit may justify its cost and learning curve. Undercut is purpose-built for one job: auto-repricing eBay listings safely above a hard floor, as simply and affordably as possible. If that is the job you need done, Undercut is hard to beat on price and speed to value.

Does Undercut support per-listing floors, or only a single account-wide minimum?
Undercut supports a unique hard floor on every individual listing. You are not forced into a single account-wide minimum that may be too low for some items and too high for others. Each SKU gets its own floor based on your actual cost, fees, and margin target for that item.
If I switch from Price Guard to Undercut, do I have to re-enter all my minimum prices?
You set each listing's Floor Price directly in the Undercut dashboard, so you only enter the minimum that matters for each item. The free 14-day trial gives you time to set up floors and watch a full reprice cycle before committing.
How often does Undercut reprice compared to Price Guard?
Undercut reprices every 15 minutes on both Pro and Scale. Free and Starter plans reprice hourly. Price Guard's reprice frequency varies by plan. For time-sensitive categories like electronics or media, the 15-minute cycle is worth evaluating directly.
What happens when my listing is already the lowest price? Does Undercut keep dropping?
No. Once your listing is the lowest-priced offer, Undercut stops. It will not race past the floor chasing a non-existent competitor. The floor is a hard stop, not a soft guideline.
Does the free plan require a credit card?
No card is required to start. The 14-day free trial and the ongoing Free plan (up to 25 listings) are accessible without entering payment details. You only need a card when you choose to upgrade to a paid tier.
