Quick Summary
- Amazon replaced the Yes/No buyer customer-service survey with a 1-to-5 satisfaction scale in mid-April 2026; announced the week of May 11 and confirmed by EcommerceBytes May 14
- Mid-range scores (2 and 3 out of 5) that previously read as borderline-positive now contribute to the Buyer Dissatisfaction Rate (BDR)
- Primary impact: self-ship (FBM) sellers providing their own customer service; FBA orders are handled by Amazon's own CX operation
- Account-health thresholds did not change; the math underneath them did, so BDR percentages are not directly comparable to last quarter

What's happening
Amazon has changed the way it computes buyer satisfaction with seller customer service. According to EcommerceBytes, the company quietly replaced the legacy Yes/No buyer-satisfaction survey with a 1-to-5 satisfaction scale last month, then announced it the week of May 11, 2026. The change directly impacts self-ship sellers (FBM) who provide their own customer service. From our vantage point running multi-account reporting, this kind of shift surfaces in catalog-level breakdowns first.
The mechanics matter. Under the old methodology, a buyer rated a contact as satisfied or not satisfied, and Amazon rolled the not-satisfied responses into the Buyer Dissatisfaction Rate (BDR). Under the new 1-to-5 scale, the middle of the distribution (the 2 and 3 ratings that previously read as borderline-positive in a binary world) now feeds the dissatisfaction calculation. The seller-forum thread on Buyer Dissatisfaction Rate Documents sellers asking why their BDR moved without any change in the underlying customer interactions.
For background on how BDR ties into broader account health, My Amazon Guy's seller performance metrics guide Walks through the dashboards. The broader context comes from Marketplace Pulse's May 14 piece on rising traffic per active seller: as competitive intensity inside the marketplace shifts, the bar for account-health metrics quietly moves with it.

Why this matters for FBM and hybrid sellers
Your BDR can move without anything changing in your service
Buyers who would previously have selected "satisfied" on a binary survey can now select a 3 out of 5. That 3 used to be invisible. It now contributes to the dissatisfaction calculation. Sellers running close to the account-health threshold should expect a noisy week or two of BDR movement that does not reflect a real change in customer experience, and should not over-correct on staffing or SLAs based on the first reading.
FBM sellers are the primary group affected
FBA orders use Amazon's own customer-service operation, so the survey change passes through to Amazon-managed contacts. The change lands hardest on FBM sellers and hybrid sellers running their own customer-service desk for self-ship orders. If you operate hybrid (some SKUs FBA, some FBM), pull the BDR specifically for the FBM cohort and benchmark separately. A single rolled-up account-health view will mask the shift.
Account-health thresholds did not change. The math underneath them did.
Amazon has not announced a new public threshold for BDR. The denominator and numerator both shifted, so the same ratio number means something different than it did six weeks ago. Bottom line: do not interpret the new BDR percentage against last quarter's. Re-baseline against the last 30 days of post-change data and watch the trend, not the absolute number.
What you should do now
- 1.
Split your account-health monitoring by fulfillment channel
If you operate both FBA and FBM, stop looking at a single combined BDR number. Track the FBM-only BDR weekly, with a 30-day rolling window, so you can see whether the new methodology is moving you toward the threshold independent of FBA performance.
- 2.
Audit your customer-service responses against the new scale
Sample 30 to 50 recent FBM contacts and ask whether the response would earn a 4 or 5 from a typical buyer, not just an unambiguous "satisfied". The gap between those two bars is exactly where the new methodology will catch you.
- 3.
Tie BDR back to operating-cost reality
Account-health risk is a P&L risk. Suppressed listings cost more than the additional CX investment to keep BDR clean. Track CX cost per order in the same view as your contribution margin so the trade-off is explicit, not implicit.
How Nova helps you operationalize the change
Nova does not surface Buyer Dissatisfaction Rate directly today. What Nova does cover is the operational layer underneath: revenue, fees, ads, fulfillment cost, and contribution margin, split cleanly by FBA and FBM cohort. That is the view you need to decide whether to invest more in customer service, prune problem SKUs, or shift a cohort to FBA.
Use Profit and Loss to see contribution margin per SKU after every fee, broken out by FBA versus FBM. Use day-to-day performance to catch contact-volume or refund spikes early. Pair both with PPC Analytics so you can see when an ad push is driving the kind of order mix that strains your customer-service desk.
The FBA seller workflow Covers single-brand operators, the brand-manager workflow Covers multi-brand portfolios, and the agency workflow Covers operators managing customer service across many seller accounts. The marketplace analytics overview and pricing page Walk through how this lands at the account level.
