Fashion resellers face a double burden that other eBay categories do not: inventory splits across dozens of size and color variations, and prices that need to move with the season. A winter puffer listed in November competes at one price point; in March it competes at a completely different one — or sits unsold. Manual repricing across hundreds of SKUs with these dynamics is not slow, it is mathematically unwinnable. The answer is automated repricing anchored by a per-item hard floor, so markdowns chase the sale without ever crossing into a loss.
A typical reseller carrying 200 garments might have 600 or more active listings once sizes and colors are split into separate SKUs. Each variation has its own cost basis, its own sell-through velocity, and its own competitive landscape. A size-small cardigan may have three competitors; the size-large has twelve. Checking and adjusting each one daily is a part-time job on its own — and the market does not wait for you to finish.
The most important habit any clothing reseller can build before automating is calculating and recording a floor for every item. Without a floor, an automated repricer will follow competitors all the way to a loss. The floor formula is straightforward: cost of goods + shipping cost + eBay fees + your minimum acceptable margin.
Worked example — a vintage denim jacket: - Cost (sourced): $18.00 - Shipping (poly mailer + label): $6.00 - eBay final value fee at 13.25%: applied to sale price - Minimum margin target: 20%
To find the floor price, solve for P where P × (1 − 0.1325) − $6.00 − $18.00 ≥ 0.20 × cost: P × 0.8675 ≥ $18.00 + $6.00 + ($18.00 × 0.20) P × 0.8675 ≥ $27.60 P ≥ $31.81
Set the floor at $31.81. Undercut will reprice aggressively below every competitor but will stop at that number — automatically, for every SKU you configure.
Clothing has two repricing modes: in-season and clearance. In-season, the goal is to hold near the market price and win sales from buyers ready to buy now. Clearance, the goal is velocity — move inventory before it becomes unseasonal dead stock, but still above the floor.
Manually switching between these modes for hundreds of listings is the exact work automation eliminates. On Undercut's Pro and Scale plans, the AI aggressiveness tuning lets you dial, per listing, how fast and how far a listing moves toward its floor — from conservative to aggressive. Sellers typically run conservative settings in peak season and shift to aggressive in the final four to six weeks of a season's sell window.
The floor stays constant throughout both phases — it is what keeps the clearance discount from becoming a loss.
The practical problem with fashion repricing is volume. If you source 50 garments a week and each generates four size-variation listings, you are managing 200 new listings weekly — on top of your existing catalog. Repricing each one by hand before the next batch arrives is impossible without a team.
Undercut connects to your full eBay catalog and reprices against a floor you set on each listing, not at the account level. That means your XS listings compete against XS competitors and your XL listings compete against XL competitors — each with the floor you set for that specific cost basis. The Scale plan (10,000 listings, plus priority support) is built specifically for sellers at this volume.
The right plan depends on your active listing count and whether you need AI aggressiveness tuning for seasonal mode-switching.
Free (25 listings): test the floor mechanic with a small capsule of your best sellers before committing. Starter at $29/month (100 listings): works for a focused boutique reseller with a tight, curated catalog. Pro at $79/month (1,000 listings, 15-minute repricing): the practical entry point for anyone running seasonal clearance strategies — the AI aggressiveness tuning is what makes the in-season vs. clearance mode switch automatic. Scale at $199/month (10,000 listings, 15-minute repricing, priority support): sourcing at volume, multiple categories, or running a small resale operation with staff.
All plans start with a 14-day free trial and no credit card required, so you can validate your floors and watch repricing work before paying anything.

Start freeHow do I set different floors for in-season versus end-of-season clearance on the same item?
You can update a listing's floor at any point — Undercut will respect the new value immediately. Many clothing sellers keep a simple spreadsheet with two floor columns (peak and clearance) and update each listing's Floor Price in the dashboard as the season shifts. The repricer holds at whichever floor is active, so there is no risk of the clearance price overshooting into a loss.
Does Undercut handle size variations as separate listings or as one listing with variants?
eBay surfaces most size variations as separate active listings in your seller account, and Undercut reprices at the individual listing level. Each size gets its own floor and its own competitor comparison, which matters because a size small and a size large often have different supply and different competitor prices.
My clothing costs vary a lot because I source from thrift stores. How do I floor items I paid different prices for?
Set the floor per listing based on that item's actual cost. If two identical jackets cost you $8 and $22 respectively, they get different floors. The formula is the same — cost + shipping + fees + margin target — but the input changes per unit. You set each listing's Floor Price in the dashboard, so two identical jackets with different costs each get the floor that matches what you actually paid.
Competitors on my clothing listings sometimes price below their shipping cost. Will Undercut match those prices?
No — that is exactly what the floor prevents. If a competitor lists below your floor (even below their own cost, which happens in race-to-bottom situations), Undercut stops at your floor and holds. You may not win every sale, but you will not take a loss on the ones you do win.
How quickly does repricing react when a competitor drops their price on a trending item during a sale event like Prime Day or a holiday weekend?
On both the Pro and Scale plans, repricing checks run every 15 minutes. During high-traffic sale events when prices shift fast, that 15-minute cadence keeps fashion sellers responsive to competitor activity, matching or beating a price drop within a single cycle rather than the next time you log in. Scale adds capacity (up to 10,000 listings) and priority support for sellers running large catalogs through those events, not a faster cycle.
