Account Health Creep, Amazon Seller Central

Account Health Creep for Amazon Seller Central. Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it.

Metrics type: Supporting Metrics • Category: Marketplace

At a glance

The early-warning alert that catches a slow, dangerous drift in account-health metrics before the headline status flips. Where Account Health Status tells you the account has already moved to At Risk, this card fires when Order Defect Rate or Late Shipment Rate is creeping upward week on week, the gradual slide that, left unchecked, becomes a suspension. It is the difference between fixing a trend and firefighting a crisis.

What it counts	A week-on-week change detector on the key account-health metrics, chiefly Order Defect Rate (ODR) and Late Shipment Rate (LSR). It surfaces metrics that are rising, even when each is still inside Amazon’s pass threshold.
Why a separate card	The status gauge is binary-ish: Healthy until a threshold breaks. This card watches the slope, so you act while the number is still green but heading the wrong way.
Fulfilment scope	Account-wide, but the creep is almost always FBM-driven, because FBM is where the seller controls shipping and service. FBA’s shipping metrics are largely Amazon’s responsibility.
Typical drivers	A courier slipping on delivery times, a warehouse falling behind on handling time, a defective batch generating returns and claims, or a seasonal volume spike outrunning the fulfilment team.
Relationship to the status	This is the leading indicator; the status gauge is the lagging result. Catching the creep here means the status never has to flip.
Refunds / claims	A rising trickle of refunds, negative feedback, or A-to-z claims often shows up here first, as ODR ticks up a fraction of a point each week.
Time window	7D (seven-day rolling, compared week on week to detect the slope)
Alert trigger	ODR or LSR up >0.2pp WoW. A rise of more than 0.2 percentage points week on week in either metric flips the card and notifies owner and operations.
Roles	owner, operations

Calculation

Calculated automatically from your Amazon Seller Central data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

A UK kitchenware seller, mostly FBM on amazon.co.uk. Three consecutive weekly snapshots leading to 21 Mar 26.

Week ending	Order Defect Rate	Late Shipment Rate	Status gauge
07 Mar 26	0.45%	2.1%	Healthy
14 Mar 26	0.61%	2.9%	Healthy
21 Mar 26	0.84%	3.8%	Healthy (just)

ODR week-on-week change (14 → 21 Mar)  =  +0.23pp  (above the 0.2pp threshold)
LSR week-on-week change (14 → 21 Mar)  =  +0.9pp   (well above threshold)
Status gauge                            =  still Healthy, both metrics under target
Account Health Creep alert              =  FIRED

Four things to notice:

1. The status gauge is still green, but the trend is alarming. ODR is under the 1% target and LSR is under the 4% target, so Account Health Status shows Healthy. Yet both metrics nearly doubled in two weeks. The creep alert exists to flag exactly this, momentum the binary status cannot show.
2. At this slope, the account breaches within a week or two. LSR went from 2.1% to 3.8% in a fortnight; one more bad week pushes it past 4% and the status flips to At Risk. Acting now is far cheaper than recovering a suspended account.
3. Both metrics moving together points at one root cause. A simultaneous rise in defects and late shipments usually means a fulfilment bottleneck, a courier problem or a warehouse falling behind, rather than two unrelated issues. That makes diagnosis faster.
4. This is the card that buys you time. Catching the slope here means a quiet operational fix (tighten handling time, switch courier, pause the worst SKUs) instead of a Plan of Action and an appeal later. The whole value is in the lead time.

The seller investigates, finds a courier consistently missing the delivery promise, and switches carrier for the affected region. The next week’s snapshot shows LSR falling back toward 2%, the creep clears, and the status never had to leave Healthy.

Sibling cards merchants should reference together

Creep is a leading indicator. Pair it with the metrics it is watching and the status it is protecting:

Card	Why pair it with Account Health Creep
Account Health Status	The lagging result this card protects. The creep alert is designed to fire before the status gauge flips amber.
Order Defect Rate	One of the two metrics whose slope this card tracks. Check it to see the absolute level behind the trend.
Late Shipment Rate	The other tracked metric, and usually the faster-moving one. A climbing LSR is the most common creep driver.
A-to-z Guarantee Claims (open)	Granted claims feed ODR. A rising open-claims count is often the source of an ODR creep.
Pre-Fulfilment Cancel Rate	Cancellations after payment are a defect that can push ODR up gradually. Watch it alongside the creep.
Negative Feedback (30d)	Rising negative feedback often precedes an ODR creep by a week or two. A useful upstream signal.

Reconciling against Amazon Seller Central

Where to look in Seller Central:

Account Health → the Customer Service Performance and Shipping Performance panels. Amazon shows the current ODR and LSR values there, but it does not present an explicit week-on-week slope. To reconcile the creep, note the ODR / LSR values across consecutive visits, the deltas are what this card computes for you.

Because Amazon shows the level and not the trend, the creep card is doing arithmetic Amazon does not display. Reconcile by confirming the underlying ODR and LSR values match; the week-on-week change is derived from those.

Timing and reporting-lag table:

Topic	Detail
Timezone	Amazon’s metric windows use the marketplace’s local timezone. Vortex IQ aligns the weekly comparison to consistent boundaries; a metric near a window edge can read slightly differently.
Rolling windows	ODR and LSR are themselves rolling metrics. A week-on-week comparison of rolling values smooths single-day noise, which is intentional, the card is looking for sustained drift, not one bad day.
Refresh cadence	The underlying metrics update on Amazon’s rolling schedule; the creep is recomputed each cycle so the slope stays current.
FBA vs FBM	FBM shipping metrics move fastest and drive most creep alerts. FBA delivery performance is largely Amazon’s responsibility and rarely the source of a creep.

Why our number may legitimately differ from Seller Central:

Reason	Direction	Why
Derived vs displayed	Trend not shown on Amazon	Amazon shows the ODR / LSR level, not the week-on-week slope. The creep figure is computed by Vortex IQ from those levels, so there is no single Amazon number to match, reconcile the inputs instead.
Window alignment	Small deltas near boundaries	The exact week boundary affects the computed change. A metric that moved on the boundary day can shift the reported slope slightly.
Rolling smoothing	Either direction	Comparing rolling metrics dampens spikes. A sharp one-day event may show as a modest creep rather than a jump.

Cross-connector reconciliation against other connectors the same seller may run:

Card	Expected relationship	What causes legitimate divergence
ebay.seller-standards-drop-alert	Marketplace peer. eBay’s standards drop alert is the equivalent early-warning on the eBay side, though eBay evaluates on a monthly cadence rather than continuously.	Independent systems and cadences. A creep on Amazon does not imply movement on eBay unless a shared fulfilment problem is behind both.
shopify.return-rate	Shared-cause signal. A defective batch or courier failure can drive a creep on Amazon and a return-rate rise on Shopify at the same time.	Separate populations; correlated only when the root cause is shared fulfilment or product quality.

Known limitations / merchant FAQs

How is this different from the Account Health Status card? The status card is the result, Healthy, At Risk, or Unhealthy. This card is the slope leading there. It fires while your metrics are still passing but trending the wrong way, so you can fix the trend before the status flips.

What does “0.2pp WoW” mean? 0.2 percentage points week on week. If your Order Defect Rate goes from 0.5% to 0.71% in a week, that is a 0.21pp rise and crosses the alert. It is a deliberately sensitive threshold, the point is to catch drift early.

Why does the alert fire when my account is still Healthy? That is by design. The value of this card is the lead time. A Healthy status with a steep upward creep is a warning that the account is heading for trouble; acting now is far cheaper than recovering later.

Both ODR and LSR are creeping at once. What does that mean? It usually points to a single fulfilment root cause, a courier missing delivery windows, or a warehouse falling behind on handling time, rather than two separate problems. Diagnose the fulfilment chain first.

Can a one-off bad day trigger this? Rarely. The card compares rolling metrics week on week, which smooths single-day spikes. It is built to catch sustained drift, not noise.

The card fired but Seller Central shows no specific “creep” number. Correct, Amazon shows the ODR / LSR level, not the trend. This card computes the week-on-week change for you. Reconcile by confirming the underlying ODR and LSR values match Seller Central.

What is the fastest way to clear a creep? Find the root cause in the fulfilment chain and fix it: tighten handling time, switch a failing courier, or pause the SKUs generating defects. Once the underlying rate stops rising, the creep clears on the next weekly comparison.
