Issue 1: Account Suspension

Account suspension is the one Seller Central problem that can end a business overnight. Amazon can deactivate your account, freeze disbursements, and pull all active listings before you finish reading the notification email.

In 2025 and 2026, suspensions happen faster because Amazon relies heavily on automated systems to police its marketplace. A bot flags something. The account gets deactivated. A human may never review it before the suspension goes through. We have seen accounts deactivated for false-positive flags (pricing velocity, reimbursement anomalies, account linkage) where the seller did nothing wrong. The automated system does not know that.

There are two situations sellers confuse. Deactivation means your account is suspended but recoverable through appeal within a set period, usually 90 days. A permanent ban means Amazon has closed the account and will not reinstate it regardless of the appeal. Knowing which one you are dealing with changes everything about how you respond.

What triggers suspensions

• Intellectual property complaints from brand owners or competitors
• Inauthentic product claims, which Amazon issues when invoices cannot be verified
• Fake reviews, including any involvement in review manipulation schemes
• Multiple seller accounts operating from the same entity without prior approval
• Manipulated or insufficient supplier invoices submitted during an authenticity review
• Improper FBA reimbursement claims. Amazon has been aggressively monitoring and suspending accounts for this since 2025.
• High order defect rate, late shipment rate, or cancellation rate crossing Amazon’s thresholds

A Plan of Action (POA) is the document Amazon requires you to submit to address a suspension. Most appeals fail because sellers write them emotionally or vaguely. Amazon’s review team reads hundreds of these. They want evidence that you understand what went wrong and that it will not happen again.

Structure your POA in three sections:

Root cause: What specifically caused the violation. Not “we may have had some issues with our supplier” but “our supplier shipped units from a secondary manufacturing facility not listed on the authorization letter we provided to Amazon.”
Corrective actions: What you have already done to fix it. Past tense. This shows Amazon the problem is resolved, not just planned.
Preventive measures: What systems you have put in place to make sure it does not happen again. Specific, verifiable systems. Not “we will be more careful.”
Read the suspension notice three times before writing a word. The exact reason Amazon states is the only reason you address. Write three paragraphs about your customer service metrics and you will get rejected, even if that record is spotless.

Issue 2: Listing Suppression vs. Listing Suspension
These are not the same thing, and treating them the same way wastes time.

A suppressed listing is hidden from search results. The listing exists. The ASIN is active. Buyers just cannot find it because Amazon is not showing it. A suspended listing is different: the ASIN is deactivated and no longer accessible at all.

What catches most sellers off guard is that suppressed listings often show no error message in your Seller Central dashboard. You check Manage Inventory, everything looks fine, and meanwhile your product has been invisible for days.

Hidden suppression triggers most sellers miss
Browse node mismatch. Your product is listed in a category Amazon does not consider appropriate for that product type. This happens when Amazon changes category taxonomy without notifying affected sellers.
Title violations. Character count violations, promotional language, or special characters trigger suppression in many categories.
Compliance flags from Amazon’s automated systems. In health, grocery, and baby categories, products can be flagged for compliance review without any notification to the seller.
Price threshold alerts. If your price deviates significantly from Amazon’s reference price or recent sales data, the listing can be suppressed even if the price is legitimate.
Image failures. Amazon requires the main image to have a pure white background (RGB 255, 255, 255) with the product filling at least 85% of the frame. Listings that fail a backend image scan are suppressed without always triggering a visible alert.

ASIN merge and split errors

ASIN merges happen when Amazon’s algorithm incorrectly consolidates two separate listings under one parent ASIN. Typically this is triggered by duplicate UPCs, similar titles, or inconsistent brand names across different sellers on the same marketplace. Unrelated products share a listing, reviews from both products get mixed together, and inventory tracking becomes unreliable.

To fix a wrongful ASIN merge, open a Catalog support case, not a general seller support case. Include the specific ASINs affected, screenshots showing the merged state, and documentation proving your product is distinct. Vague descriptions get no action. Give them the evidence they need to make the call quickly.

ASIN splits work the same way. Same fix, same documentation requirement.

Issue 3: Stranded Inventory

Stranded inventory is FBA stock sitting in Amazon’s warehouses with no link to an active listing. It is not generating sales. It is generating storage fees. And most sellers do not notice it until the number is already significant.

The two most common causes require different fixes:

• Deleted listing: Someone deleted the listing from your account (or Amazon removed it) while inventory was still checked in. The fix is to relist the product and link the existing inventory.
• SKU mismatch: The SKU in your Seller Central account does not match the FNSKU on the units at the warehouse. This usually happens after a listing rebuild or a bulk upload error. The fix requires a removal order followed by a relabel and resend, or a case for inventory reconciliation.

How to find and fix stranded inventory

Go to Inventory > Fix Stranded Inventory. The dashboard shows every stranded unit with a reason code. Read the reason code before deciding on a fix, because the steps differ depending on whether the issue is a listing problem, a category restriction, or a pricing error. Do not ignore small numbers. A product with 10 units stranded at $40 per unit costs you $400 in potential revenue, plus storage fees compounding every month those units sit.

Issue 4: Buy Box Suppression

Over 80% of Amazon purchases go through the Buy Box. When it disappears from your listing, conversions drop almost immediately. Most sellers notice it when they see a sudden traffic dip and find their listing showing “See All Buying Options” instead of the Add to Cart button.

What causes Buy Box suppression

Pricing is the most common trigger, but it is more specific than most guides explain. Amazon’s algorithms do not just compare your price to other sellers on the same listing. They scrape external websites. If your product is listed for less on Walmart, Target, or your own DTC site, Amazon will suppress your Buy Box even if you are the only seller on the Amazon listing.

This is price parity enforcement, and it catches brands by surprise. They lower their Shopify store price for a promotion. Two days later the Amazon Buy Box is gone.

How to recover your Buy Box

• Check if your product is listed for less on any external channel. Match prices or raise the external price.
• Review your seller performance metrics in the Account Health dashboard. Any metric below threshold will affect Buy Box eligibility.
• Make sure your FBA inventory level is healthy. Low stock relative to demand triggers algorithmic demotion.
• If you use repricing software, audit it. Automatic price changes driven by repricing tools can accidentally push your price below Amazon’s fair pricing policy floor.

Issue 5: FBA Inventory Capacity and 2026 Fee Changes

Amazon capped FBA inventory at roughly 5 months of sales volume in mid-2025, down from the previous 6-month allowance. For high-velocity sellers who carried deeper buffer stock, this created immediate tension with their replenishment cycles, and Amazon also reinstated product-level restock limits for individual SKUs on top of the account-wide cap.

Your capacity limit is tied to your IPI score. The Inventory Performance Index measures how efficiently you manage FBA stock. Keep it above 400 to avoid capacity restrictions.

The 2026 FBA fee changes

Amazon confirmed that 2026 FBA fees will increase by an average of $0.08 per unit, with no new fee categories introduced. That sounds minor. On a high-volume SKU doing 5,000 units per month, it is an extra $400 every month.

The fee that caught most sellers unprepared is the Low-Inventory-Level Fee (LIVE). It applies when your inventory stays too low relative to historical demand. Sellers running FBA stock at 2 to 3 weeks of cover are probably triggering it already.

Issue 6: Listing Hijacking and Counterfeit Defense

This is the issue zero other guides on this SERP cover. That does not mean it is rare.

Listing hijacking is when a bad actor jumps on your ASIN, usually at a lower price, wins the Buy Box temporarily, and ships counterfeit, damaged, or wrong products to buyers. The negative reviews and A-to-z claims land on your listing even though you were not the fulfilling seller. Amazon assigns reviews to the listing regardless of who shipped the order.

How to detect a hijacker

• Check your listings weekly for unexpected seller count changes. If you are the only authorized seller and suddenly see two, investigate immediately.
• Order a test unit from the new seller. Document the unboxing with photos and video. Note every discrepancy from your legitimate product.
• Check whether the new seller has recent feedback from other brands’ customers. Hijackers often operate across multiple listings at the same time.

How to remove them

Filing a generic IP complaint is the starting point, but it often takes longer than you need. Faster approaches:

• Transparency Program: Every unit gets a unique serialized code that Amazon scans before shipping from FBA. A unit without a valid code cannot be sent to a customer. This is the most reliable prevention mechanism for high-volume brands.
• Brand Registry Report a Violation tool: Brand-registered sellers get access to a dedicated IP complaint pathway that is processed faster than standard seller support cases. Document every piece of evidence before submitting.
• Amazon’s Counterfeit Crimes Unit (CCU): For persistent or large-scale counterfeiting, the CCU works directly with law enforcement. Not a quick fix, but it results in real prosecutions and permanent removal.

Issue 7: Account Health Metrics

Amazon tracks your performance across four main metrics in the Account Health dashboard. Crossing any threshold triggers progressive consequences: a warning, then listing restrictions, then account suspension.

ODR is the one that matters most. It is a rolling 60-day metric and includes negative feedback, A-to-z Guarantee claims, and credit card chargebacks. A single bad week does not immediately destroy your ODR because the 60-day window smooths it out, but a sustained period of poor customer experience will.

Check the Account Health dashboard directly during peak selling periods. Do not rely on email notifications. Those notifications can sit unread while your metric is already in dangerous territory.

Issue 8: Technical Glitches and Downtime

Seller Central has technical problems regularly. In March 2026, sellers reported widespread issues affecting the Buy Box, purchase functionality, and basic dashboard navigation. The forum threads went up within minutes of it starting.

Before spending an hour troubleshooting what you think is an account problem, check whether the issue is platform-wide:

• Downdetector shows real-time user-reported outages.
• The Amazon Seller Central forums usually surface system-wide issues within 30 minutes. Search before posting.
• IsItDownRightNow gives a quick infrastructure check.

Browser-specific issues

Some Seller Central problems are browser problems, not account problems. Microsoft Edge users have reported a garbled text issue after OTP login where the dashboard renders unreadable symbols instead of the normal interface. Chrome or Firefox resolves this.

If your dashboard is loading slowly or certain menu items are missing, clear your cache and cookies completely. Not just the last hour. Clear everything for Seller Central, then reload in a fresh browser window.

Issue 9: Seller Support and Escalation

Amazon’s seller support is inconsistent. You might get a knowledgeable agent who resolves your issue in one contact, or you might get four transfers and a generic response that misses the point entirely. The difference is usually which team you reach.

When you open a case, document everything before you click submit. Include the ASIN, the case ID from any previous related contact, screenshots of the issue, and a specific description of what you need resolved. Vague cases get generic responses.

If a case has been escalated three times without resolution, use the Request an Escalation option in the case log to reach a senior review team. This is not advertised prominently, but it exists and it works.

Issue 10: Pricing Errors, Coupon Failures, and Pricing Alerts

Amazon flags listings when prices deviate significantly from the reference price or recent sales data for that product. There is no fixed number. The trigger is relative to category norms and historical pricing, so a legitimate price can still look anomalous to the system and trigger suppression.

Coupon failures follow specific rules that most sellers do not discover until a coupon stops working. The discount must be at least 5%. A reference price must exist. Your account health must be above Amazon’s threshold for promotional eligibility. If any condition fails, the coupon will not apply without any notification.

Automated pricing tools (repricers) carry their own risk. They can push your price below Amazon’s fair pricing policy floor, which triggers suppression or a pricing alert. If you use a repricer, set floor prices manually and audit them after any category-wide price movement.

Issue 11: PPC and Advertising Problems

Amazon advertising has gotten more expensive. CPC has risen across most major categories in 2025 and 2026, and sellers running the same campaign structure they built two years ago are seeing the same spend produce a lower return.

Three problems we see most often:

Keyword cannibalization. The same keyword is being targeted across multiple ad groups or campaign types, so you are bidding against yourself and inflating your own CPC. Run a search term report and identify keywords appearing in more than two active campaigns, then consolidate.

Budget exhaustion before peak hours. Your daily budget runs out by early afternoon and you lose traffic during the evening, which is typically higher-converting. Either increase budget or use dayparting rules to shift spend toward peak hours.

Broad match without negative keywords. Broad match campaigns generate impressions on irrelevant searches. Without active negative keyword lists, a significant share of broad match spend goes to searches that will never convert. In our experience running campaigns across client accounts, it tends to be 20-30% of spend. Run a search term report weekly and add non-converting searches as negatives.

Attribution reporting in Amazon lags by 48-72 hours. Do not make campaign changes based on same-day data. The full attribution window needs to close before bids get adjusted.

Issue 12: AI-Based Enforcement in 2026

No other guide on this topic is talking about this. It matters more than most sellers realize.

Amazon’s compliance, listing, and account enforcement systems are increasingly automated. Bots flag accounts for related accounts, velocity anomalies, listing discrepancies, and reimbursement patterns. In many cases, the initial enforcement action happens without any human review. A human only gets involved if the seller appeals and only if the appeal meets certain criteria.

What this means in practice: the first notice you receive is not always accurate. Automated systems generate false positives. But the appeal process was designed for human-reviewed decisions, so contesting a bot-triggered suspension requires the same precision as contesting a human one. The bar does not go down just because a machine made the call.

The sellers who handle this well keep detailed records from day one. Supplier invoices organized by product and date. Compliance certificates for any regulated category. Shipment records with tracking. Reimbursement claim history. When an automated flag hits, you need to produce documentation immediately, not spend three days gathering it.

Issue 13: Amazon’s APEX Patent System

Most sellers have never heard of APEX. That changes the moment they receive a patent dispute notice.

Amazon Patent Evaluation Express is Amazon’s internal patent tribunal. It is a private adjudication process designed to handle utility patent disputes between brand owners and third-party sellers without going to federal court. A 2025 study from UC Berkeley Law documented how APEX operates and the risks it creates for sellers who do not understand what they are responding to.

If you receive an APEX notice and respond incorrectly, or fail to respond, you risk permanent listing removal. APEX decisions are binding within the Amazon ecosystem. The rules are strict and the timelines are short.

Treat an APEX notice like a legal document. Consult with an IP attorney who has Amazon experience before responding. Standard seller support channels cannot help you here.

Best Practices Checklist

These are the daily and weekly checks that prevent most of the issues above from becoming crises.

What to Do Now

Start with the Account Health dashboard and the Suppressed Listings report. These two surfaces catch the majority of active issues before they become critical. If your IPI is below 400, fix your stranded inventory before your next inbound shipment. If your Buy Box has disappeared or your ODR is above 0.7%, treat it as urgent today.

For anything involving account suspension, APEX notices, or IP disputes, get qualified help before responding. A rushed appeal or a poorly handled legal notice can make a recoverable situation permanent.
