Amazon Makes Passkeys Required on September 29. Your Shared Seller Central Login Dies With It.
Amazon emailed sellers on September 15 that passkeys become required on a rolling basis starting around September 29. Passwords stay on file for recovery only. The part that will actually hurt is the shared login your VA, your warehouse, and your agency all use, because every one of them now needs a separate secondary user account with an email address that has never touched Amazon.

Between September 8 and September 14, Walmart added prescriptive recommendations to Growth Incentives, delivery speed, returns, and Listing Quality. Seller Center stopped reporting metrics and started telling you what to do. Those instructions are optimized for Walmart GMV, which is not the same thing as your contribution margin.
Read → OperationsWalmart Opened a Faster Ocean Lane From China to WFS. Use It for the Gap Container, Not the Q4 Plan.
Priority Ocean cuts China to Los Angeles port-to-door from about 23 days to as little as 15. It is also once a week, three ports only, capacity-rationed, unpriced until you book, and validated on 27 shipments. Here is where it actually earns its premium.
Read → OperationsAmazon Just Published Its Parcel Peak Surcharges. If You Self-Fulfill, Your Q4 Cost Model Is Missing a Line.
Amazon Shipping posted its 2026 peak surcharge table on September 2. Three windows, a per-package fee of $0.50 to $0.75, and handling fees that run from $8.75 to $590. Most sellers modeled FBA peak fees in August and never went back for the parcel side.
Read → OperationsWalmart Cut the Walmart+ Badge Lookback to 14 Days. That Makes It a Weekly Metric, Not a Monthly One.
You can now earn the Walmart+ badge in two weeks instead of a month. You can also lose it in two weeks. Going into Q4, that turns a set-and-forget program into something someone on your team has to watch every Monday.
Read → OperationsWalmart Just Put a Price on Something WFS Did for Free. Run the ITS Breakeven Before Your Next Q4 Shipment.
Walmart used to spread your WFS inventory across the country at no charge. Now it is a per-unit fee with an opt-out most sellers will click straight past. The dimensional weight rule creates a cliff where 0.2 lb triples your cost per unit.
Read → OperationsAmazon Just Made Liability Insurance Mandatory in 11 Categories With No Sales Threshold. Deadline Is November 2.
A September 3 Seller Central announcement removes the $10,000 monthly trigger for 11 enhanced-safety categories and forces Mainland China sellers into Amazon's own insurance program. The category list is wider than sellers expect. Air fryers, tires, and mattresses are on it.
Read → OperationsAmazon Starts Enforcing a 90% Business Hour Delivery Rate on September 30. FBM Sellers Have Three Weeks.
Seller-fulfilled offers to Amazon Business customers now have to arrive during the buyer's operating hours, not just by the promised date. Miss 90% and your B2B offers can be deactivated on October 30, right as Q4 volume peaks.
Read → OperationsWalmart Just Made Your October Sales Four Times Riskier
Walmart is extending the holiday return window so that most items bought from October 1 through December 31, 2026 can be returned through January 31, 2027. That turns a 37 day liability on an October order into a 122 day one. Here is the math, the cash flow problem, and what to fix before October 1.
Read → OperationsAmazon Now Lets You Bid for Two-Hour Delivery. At Most Margins, Breakeven Needs a 9 Percent Lift.
Amazon has started inviting FBA sellers to bid a per-unit price to place additional products in its Sub Same Day network, the two-hour service running out of dedicated sites near 2,300 metro areas. The bid is not the expensive part. Here is the breakeven formula, why Amazon's 12 percent lift figure is the wrong number to plan against, and the inventory cost nobody is quoting.
Read → OperationsWalmart Now Puts Duties Into the Shelf Price for China Sellers. Somebody Still Eats the Estimate Gap.
Walmart updated Ship with Walmart Cross Border on August 26, 2026. Carriers pay duties upfront and bill the seller after final amounts are confirmed, while shoppers see one landed price. That is a conversion win with a margin variable attached, and it lands five weeks before peak.
Read → OperationsWalmart Can Switch Off Your Entire Storefront Without Telling You. We Watched It Happen.
On August 28, 2026, a client's entire Walmart catalog went invisible on walmart.com while Seller Center reported perfect account health. The cause was a GMV pause, an internal review of selling limits triggered by growth. Here is how we identified it and what to check on your own account.
Read → OperationsAmazon Just Banned Pledging Your Payouts. Check Your Q4 Inventory Loan Before You Draw On It.
The updated Business Solutions Agreement took effect August 24, 2026. It prohibits transferring your rights under the agreement and, separately, pledging them as collateral. If your Q4 inventory is being financed against Amazon disbursements, that facility is now in scope.
Read → OperationsWalmart Funded 11,000 Rollbacks With a $2.9B Tariff Refund. Check Whether You Are Owed One Too.
Walmart's Q2 FY27 results, released August 20, 2026, disclosed nearly $2.9 billion in IEEPA tariff refunds and more than 11,000 rollbacks funded with them. The same refund pool is open to sellers who were the importer of record, and it is not automatic.
Read → OperationsAmazon Just Opened AWD in Five European Markets. It Landed Too Late to Save Your Q4.
Amazon Warehousing and Distribution went live in the UK, Germany, France, Italy and Spain on August 20. It is a real answer to FBA capacity limits, but the launch timing means most sellers cannot get Asia-origin inventory through it before peak. Here is what to do with it now and what to plan for 2027.
Read → OperationsWalmart Deprecated Five Shipping Settings Endpoints and the Replacement Does Not Ship Until August 31
Walmart deprecated the Simplified Shipping Settings APIs on August 4, 2026. SSS 2.0 launches August 31. If your channel software, 3PL, or in-house integration manages Walmart shipping templates through those endpoints, your delivery promise automation can go quiet in the weeks you least want it to. Here is what changed and the one question to ask your provider this week.
Read → OperationsWalmart Just Dropped the Auto Care Association Tollbooth on Auto Parts Listings. Brand and Part Number Are Now Enough.
On August 17, 2026, Walmart simplified automotive item setup. AAIA Brand ID and Part Terminology ID are no longer required. You now need an accurate Brand and Manufacturer Part Number, plus compatibility coverage. For resellers and non-Autocare brands that have been locked out of the fitment widget, this is the cheapest category unlock Walmart has shipped this year, and it lands eight weeks before peak.
Read → OperationsAmazon Is Forcing You to Reauthorize Every Agency and Tool in September. Ignore the Email and They Go Dark.
Amazon retired the old Seller Central invite process on August 10, 2026. In September, sellers get an email requiring them to reauthorize every service provider with account access. Miss the deadline and all existing access expires. Reauthorize without checking role coverage and your partners come back with less access than they had.
Read → OperationsWalmart Just Put Listing Quality Behind an API. If You Have More Than 300 SKUs, Stop Doing Catalog QA by Hand.
On August 17, 2026, Walmart added LISTING_QUALITY and CONTENT_QUALITY report types to the On-request Reports API. Listing quality scores, score drivers, issues, recommended actions and attribute-level content gaps now come back as a file instead of a dashboard you click through one item at a time. Here is what shipped and the weekly workflow to build on it.
Read → OperationsAmazon Kills the Variation Wizard End of August. Fix Your Listing Ops First.
Amazon is retiring the Variation Wizard by the end of August 2026 and moving all parent-child work to the Add Products page. The new flow hands you a pre-filled spreadsheet with the full family structure, which is faster once your team knows it and a source of broken listings if they do not. Here is what changes and what to rebuild before Q4.
Read → OperationsAmazon Retired the Old Seller Central. Your Team's SOPs Just Broke.
The new Seller Central is becoming the default for every seller this month, and the opt-out is gone. Six workspaces replace the old menus, one Action Center now funnels every account-health alert, and an AI assistant can act on your account when you let it. Here is what changes for your ops team and the blind spots to close before Q4.
Read → OperationsYour First Hard Q4 Deadline Is About Three Weeks Out. Here Is the FBA Calendar That Protects Your Prime Badge.
Amazon set its 2026 holiday fee schedule and inbound deadlines. Peak fees are flat, but the send-by dates are the real story, and the first one lands the week of September 2. Here is the calendar and the two things sellers get wrong about the peak fee.
Read → OperationsAmazon Now Makes You Label AI People in Your Images. Audit Your Catalog Before Q4.
On July 23, 2026, Amazon told third-party sellers they must tag any listing image or A+ module containing a photorealistic AI-generated person. It follows New York's synthetic performer disclosure law, it applies marketplace-wide, and Amazon is adding a shopper-facing label. Here is what changed, why it can cost you conversion in Q4, and the audit to run this week.
Read → OperationsWalmart Is Killing Delegated Access Keys. Reauthorize Before October 1 or Your Tools Go Dark.
Walmart stops issuing new Delegated Access keys on July 30, and existing keys stop working on October 1, 2026. If your listing, pricing, and order tools run on the old method, they break the day before Q4. Here is what to check now.

Sellers are reporting sharply lower FBA inbound caps this month, right as Q4 planning starts. Here is how to protect your best SKUs and build the hybrid fulfillment buffer that keeps you in stock through peak.
Read → OperationsAmazon Is About to Judge You on When the Carrier Shows Up
Starting September 30, professional sellers need a Business Hour Delivery Rate of 90% or higher on seller-fulfilled orders to Amazon Business buyers. Miss it by October 30 and your seller-fulfilled offers get deactivated for B2B customers. The uncomfortable part is that the metric measures something you do not directly control.
Read → OperationsSeller Fulfilled Prime Just Got Harder. You Have Until October 17 to Fix It.
Amazon raised SFP delivery speed thresholds across all three size tiers on July 6. Standard-size one-day coverage moved from 30% to 40% of Prime page views. A grace period on speed metrics runs until October 17, which is the only reason this is not already an emergency.

The U.S. has no VAT and no national sales tax. Instead, each state sets its own rules and you can owe tax simply by selling enough into a state. Here's how it actually works.
