Selling branded goods on eBay means juggling two different minimums: the brand's Minimum Advertised Price (MAP) and your own breakeven floor. Get either one wrong and you're either violating an authorized-dealer agreement or selling at a loss. Automated repricing makes this more urgent — a bot set too aggressively can race through both limits in minutes. This guide explains what MAP means in an eBay context, how to calculate your true breakeven floor, which number to use when they differ, and exactly how to encode the result as a hard floor in Undercut so repricing never crosses either line.
Minimum Advertised Price is a unilateral pricing policy set by a brand or manufacturer. It specifies the lowest price at which an authorized reseller may publicly advertise a product. The key word is advertised: MAP governs the price displayed in a listing, not necessarily the price a buyer pays after a private Best Offer negotiation — though many brand agreements have tightened this distinction in recent years, so always read your specific dealer agreement.
eBay does not enforce MAP on the platform's behalf. There is no system-level block preventing a listing from going below a brand's MAP figure. Enforcement is entirely contractual: if you violate MAP, the brand can terminate your authorized-dealer status, cut off wholesale supply, or pursue civil remedies. The consequences are real, but they come from the brand, not from eBay.
This means the burden of compliance falls entirely on you — and on any repricing software you use. A repricer that blindly chases the lowest competitor price will happily list a $200 MAP item at $149 if a grey-market seller goes there first. Your only reliable protection is a hard floor set at or above the MAP figure for every affected listing.
Before you can set a sensible floor, you need to know what it actually costs you to sell a unit. Many sellers anchor on their wholesale cost and forget the stack of fees sitting on top.
Here is a worked example. Suppose you source a Bluetooth speaker for $45. The item sells for $89.99 on eBay. eBay's Final Value Fee on most Electronics listings is 13.25% of the total sale amount (item price + shipping), capped at $750 per item — so on $89.99 that is roughly $11.92. Add a $0.30 per-order transaction fee. If you use a promoted listing at 5%, that is another $4.50. Shipping and packaging costs $8.00. Payment processing (included in eBay's managed payments) is already captured in the FVF. Total costs: $45.00 + $11.92 + $0.30 + $4.50 + $8.00 = $69.72. Your breakeven price is $69.72 — sell below that and you lose money on every unit.
Most sellers also want a minimum margin, say 15%. Apply that: $69.72 ÷ (1 − 0.15) = $82.02. That is your margin-protected floor. Round up to $82.99 to keep a clean price point, and that is the number you should never go below — regardless of what competitors do.
Once you have both figures, the rule is straightforward: your hard floor must be the higher of the two numbers.
Scenario A — MAP is higher than your breakeven floor. Imagine your breakeven floor (with 15% margin) is $82.99, but the brand's MAP is $99.95. Your hard floor is $99.95. If you set it lower, you risk violating your dealer agreement even though you would still be profitable. Undercut's repricing will never push your listing below $99.95, so you stay compliant automatically.
Scenario B — Your breakeven floor is higher than MAP. Your breakeven floor is $82.99, but the brand's MAP is $74.99 (perhaps the brand set MAP years ago and wholesale costs have since risen). Your hard floor is $82.99. You cannot profitably honor the old MAP, so you either need to negotiate with the brand, find a cheaper supply source, or accept that this SKU is unviable at current costs. Setting the floor at MAP in this scenario would mean losing money on every repriced sale.
Scenario C — No MAP applies. You are selling unbranded goods or secondhand items with no MAP restriction. Your hard floor is simply your margin-protected breakeven. This is the most common situation for general eBay resellers.
A practical way to track this: maintain a simple spreadsheet with columns for SKU, COGS, all-in cost, breakeven floor, brand MAP (if any), and the final hard floor you load into Undercut. Review it whenever your costs or brand agreements change.
Undercut lets you set a per-listing hard floor (and an optional ceiling) on every eBay listing you connect. The hard floor is a strict lower bound — the repricing engine will never set your price below it, regardless of competitor activity. This is the mechanism that protects both your margin and your MAP compliance simultaneously.
To configure it: in your Undercut dashboard, open any listing and enter the hard floor value in the Floor Price field. Using the example above where the brand MAP is $99.95 and your breakeven floor is $82.99, you enter $99.95. Undercut will then reprice competitively down to $99.95 but stop there. If the lowest competitor drops to $94.99 — below your floor — Undercut holds your price at $99.95 rather than chasing them.
For sellers on the Pro and Scale plans, Claude AI-powered aggressiveness tuning lets you set, per listing, how quickly and how deeply Undercut reprices toward the floor. You might set a listing you want to move more aggressively (repricing faster and closer to the floor), while setting a low-volume collectible conservatively to preserve margin. Critically, the AI aggressiveness setting is one you choose per listing and it never overrides the hard floor — it only governs the pace and depth of repricing within the floor-to-ceiling range.
If you have hundreds of listings with MAP restrictions, the practical workflow is to calculate the right floor for each in your own spreadsheet, then enter each listing's Floor Price in the dashboard. Keeping the math ready makes setting many listings quick.
The most expensive mistake sellers make is setting a floor based on the item's purchase price alone, forgetting eBay fees, shipping, and promoted listing costs. As the worked example in section two shows, fees alone can add $16–$20 to the cost of a $90 item. A floor set at your wholesale cost will have you selling at a consistent loss.
The second common mistake is syncing floors once and never updating them. eBay's fee schedule changes periodically. Wholesale costs fluctuate. Brand MAP policies get revised — sometimes upward, sometimes downward. A floor that was accurate six months ago may now be too low. Build a quarterly review into your workflow, or trigger a review whenever you receive a new wholesale invoice or a MAP policy update email from a brand.
A subtler mistake is applying the same floor to identical SKUs bought at different costs. If you have 50 units purchased at $40 and a later batch of 30 units purchased at $52 because of supply chain increases, your blended cost is different from either lot. Decide whether to use average cost, FIFO cost, or worst-case cost as your floor basis — most sellers use worst-case (highest COGS) to be conservative.
Finally, do not confuse eBay's own promotional tools — like Markdown Manager or Promoted Listings — with floor violations. Offering a 10% promotional discount on a $99.95 MAP item could push the displayed price to $89.96, which is below MAP. If you run promotions, check whether your brand agreement permits temporary promotional prices below MAP, and if not, exclude MAP-restricted listings from those campaigns.

Does eBay enforce MAP policies on behalf of brands?
No. eBay does not monitor or enforce brand MAP policies at the platform level. Your listing can go below MAP without eBay intervening. Enforcement comes entirely from the brand — they may audit authorized resellers, send warning notices, or terminate dealer agreements. The only reliable automated safeguard is a hard floor set at or above the MAP figure in your repricing software.
Can I honor MAP on the listing price but accept Best Offers below MAP?
It depends on the specific brand agreement. Some MAP policies cover only the advertised (listed) price and explicitly allow Best Offer negotiations below MAP, while others prohibit final transaction prices below MAP regardless of how the sale originates. Read your dealer agreement carefully. If it is ambiguous, ask your brand rep in writing so you have a clear record.
What happens in Undercut if a competitor drops below my hard floor?
Undercut holds your price at the hard floor and does not reprice further downward. You will not match or undercut a competitor who is selling below your floor — whether they are violating MAP, selling grey-market goods, or simply losing money. Your listing stays at the floor price until that competitor's price rises back above your floor, at which point normal repricing resumes.
How often does Undercut check competitor prices on Pro and Scale plans?
On both the Pro plan ($79/mo) and the Scale plan ($199/mo), Undercut checks and reprices every 15 minutes — Scale's difference is capacity (up to 10,000 listings) and priority support, not a faster cycle. The 15-minute interval is fast enough to respond to most competitor price changes within a single shopping session, while the hard floor ensures rapid repricing never accidentally breaches your minimum.
Can I set a different floor for each of my listings?
Yes. Undercut supports per-listing floors, so every SKU can have its own floor reflecting its unique cost structure and MAP requirement. For large catalogs, calculate the right floor for each item in your own spreadsheet first, then enter each listing's Floor Price in the dashboard. Per-listing floors are available on every plan, including Free.
