Brand Registry, MAP & resellers
A MAP policy only works if somebody checks prices every week and acts the same week. The document is the easy part. What makes it real is a short routine: look at the sellers on your ASINs, compare their advertised prices against your floor, work out where their stock came from, and apply the consequence you wrote down.
This article is about that routine rather than the policy text. The text, and the legal reasoning behind writing it as a unilateral statement, is in the Amazon MAP policy article. Here the question is operational: who does the checking, what they look at, and what happens next.
The weekly check, in twenty minutes
Pick a day and keep it. Friday morning works because weekend promotional pricing is the most common violation window.
Open each of your ASINs and list the offers. Not just the Buy Box price — the full offer list, including sellers who are priced above you and therefore invisible on the page. A seller sitting above MAP today is still a seller you did not know about.
Record seller name, price, condition and fulfilment method. A simple sheet with one row per seller per week is enough to see patterns. The pattern is what matters: a seller who appears, undercuts for four days and disappears is liquidating a specific batch, and that tells you something different from a seller who is permanently at your floor minus two dollars.
Compare to the floor. Advertised price, not the price after a coupon the seller funds themselves. Your policy should say which one you mean.
Check off-Amazon. Run a search for the product name on the open web. Amazon's own pricing systems watch other retailers, so an off-Amazon listing at a bad price can drag your Buy Box down without any Amazon seller being involved. This is the source sellers forget.
Twenty minutes, every week, by the same person. Delegate it, but give them the sheet and the escalation template so they are not asking you what to do each time.
Working out where the stock came from
This is the hard part and the part that determines whether enforcement does anything. Removing a listing without closing the source means a new listing next month.
Start with your own accounts. Cross-reference the timing of the low price against your recent shipments. A violation appearing three weeks after a large order to one account is not a coincidence.
Use lot codes. Put a lot or batch code on every case you ship and record which code went to which account. If you can buy a unit from the offending seller and read the code, you know the source. Without codes, you are guessing.
Buy a unit. It costs you one unit and a few days, and the packaging, the lot code and sometimes the shipping label tell you most of what you need. If the item arrives with a Transparency code, you can check whether it was issued for that channel.
Consider the leaks you did not create. Returns sold to liquidators, a retail account's clearance, a distributor's customer, a pallet from a closed store. Not every off-price unit came from a bad actor; plenty came from an ordinary commercial process nobody thought about. Your reseller agreement is where you narrow those routes, and the relevant clauses are in the Amazon reseller agreement.
Accept that some are untraceable. If a seller will not say and the unit gives nothing away, you are left with the general enforcement tools, which are covered in how to remove unauthorized sellers.
The escalation ladder
Write it once, apply it identically every time. Predictability is what changes behaviour; severity mostly is not.
Step one, the notice. A short email naming the ASIN, the advertised price, the floor, and a date by which it should be corrected. Attach the policy. Keep the tone administrative rather than aggravated, because most first violations are an employee following a pricing rule rather than a decision to defy you.
Step two, the hold. If it is not corrected, the next order does not ship. Say so in writing before the order is due, not after they have committed inventory.
Step three, removal. The account comes off the authorised list and stops receiving stock. Update your published authorised list the same week, because that list is what makes step three mean anything to everyone else.
Step four, nothing. There is no step four for most brands. Litigation over pricing is disproportionate unless something else is also happening — counterfeits, trademark misuse, contract breach with real damages.
The one addition worth making: tell the rest of your accounts, briefly and without naming anybody, when a relationship ends over pricing. Accounts hold a line they believe is being held with others.
What to do about sellers you never supplied
A meaningful share of the sellers on your ASIN never bought from you directly, and your policy has no hold over them at all. This is where brands waste the most effort.
Sort them into three groups.
Legitimate resellers of genuine product. They bought somewhere downstream. Your policy does not bind them, and Amazon will not remove them. The only real fix is upstream: find and close the leak. You can also make the ASIN unattractive — bundle differently, change the case configuration, or move the main offer to a variation they cannot get.
Sellers of counterfeit or materially different product. These are an intellectual property matter and the Brand Registry reporting route applies. Do not file a price complaint as an infringement report; file the infringement you can actually evidence.
Sellers of your product in a condition you do not warrant. Expired, repackaged, missing components, stripped serials. This is often the strongest ground you have, and it is frequently overlooked because brands fixate on price instead.
Knowing which group a seller is in before you act is most of the skill here. The tools for each are different, and using the wrong one burns credibility with the teams who process your reports.
Setting the floor so the policy is followable
A floor that leaves a reseller no margin will be broken, and no amount of enforcement changes that. Work the numbers from the reseller's side before you publish.
Take a made-up product: retail 39 dollars, wholesale 18 dollars on a case of twelve. An online reseller pays a marketplace referral fee, fulfilment, and carries returns. If your floor is 32 dollars, they have a workable margin and a reason to follow it. If your floor is 37 dollars and their all-in cost is 26 dollars, they will still make money at 37 — but the first time they have a slow month, the temptation to clear stock at 29 is strong, because your floor sits so far above their break-even that discounting still looks profitable.
The uncomfortable corollary is that your own Amazon price is part of the system. If you run frequent deep promotions on your own listing while holding resellers to a strict floor, you have taught them the floor is decorative. Consistency on your side is not a nicety, it is the enforcement mechanism.
Pricing the wholesale channel so it does not fight your Amazon channel is the underlying problem, and it is worked through in Amazon private label vs wholesale and wholesale for Amazon brands.
Deciding which accounts are worth the trouble
Enforcement costs revenue. Every account you cut off is money you are choosing not to take, and a brand that cannot make that choice will not have a policy for long.
The judgement is easier when you have more accounts than you need. A brand with three wholesale customers cannot afford to lose one, and everybody in the relationship knows it. A brand with twenty-five can enforce a line without flinching, and the accounts behave accordingly.
So the real answer to chronic MAP problems is often pipeline rather than policy: find more of the right buyers, so no single one has leverage over your pricing. Paste your listing into WholesalePilot and the preview shows which distributors and retailers would plausibly stock the product, which is where that pipeline starts.
Questions Amazon brands ask about enforcement
How often should I check? Weekly is enough for most catalogues. Daily during a peak season if you have had problems.
Should I use a monitoring service? Once the catalogue or the seller count gets past what one person can eyeball, yes. Below that, a spreadsheet is fine and gives you a better feel for the patterns.
What if the violator is Amazon Retail? Amazon sets its own prices. If you sell through Vendor Central, your policy does not bind them, and the lever is the cost price you negotiate.
Can I fine a reseller? No. The lever is supply.
Does a coupon count as advertising below MAP? Depends on your policy, which is why the policy should say. Define it before it comes up.
Is it worth cutting off a big account over price? Sometimes it is, and the decision is easier the more alternative accounts you have lined up.
