The Amazon Late Shipment Rate — LSR — is a performance metric on your Seller Central Account Health dashboard that measures the percentage of seller-fulfilled orders shipped after their expected ship date. For wholesale sellers who use Amazon FBA exclusively this metric is almost always zero — because Amazon handles fulfilment and ships every FBA order on time independently. However many FBA sellers also operate a small number of merchant-fulfilled listings alongside their FBA catalogue — perhaps for oversize products products not yet sent to FBA or items they sell locally — and for those sellers the Late Shipment Rate becomes a real and manageable metric that can affect their account health if not properly monitored.

We are Brandhunterz Ltd — a UK registered wholesale sourcing company (Company No: 15342697) — and in this complete guide we explain exactly what the Late Shipment Rate is how it is calculated what the threshold is why it matters for your account health how to check it in Seller Central and precisely what actions FBA sellers with merchant-fulfilled listings need to take to keep it consistently within Amazon’s acceptable range.

What Is the Late Shipment Rate

The Late Shipment Rate is the percentage of seller-fulfilled orders across your account for which you confirmed shipment after the expected ship date set at the time the order was placed. Amazon calculates the LSR across two separate rolling windows — a 10-day window and a 30-day window — and applies enforcement based on whichever window is in breach. Here is the exact calculation:

An order counts as late shipped when you confirm the shipment in Seller Central after the expected ship date shown on the order — not after the expected delivery date. The expected ship date is typically the same day or the next business day after the order is placed depending on your handling time settings. Confirming shipment on time even if the physical parcel has not yet been collected is not sufficient — the confirmation must be submitted before the expected ship date deadline shown on each order.

The Late Shipment Rate Threshold

LSR Status	Rate	Account Health Implication
🟢 Healthy	Under 4%	No risk — continue monitoring weekly
🟡 At Risk	Approaching 4%	Performance notification likely — immediate review of merchant-fulfilled dispatch process required
🔴 Critical	At or above 4%	Account suspension risk — Amazon may deactivate merchant-fulfilled listings or entire account

Why Pure FBA Sellers Rarely Have an LSR Problem

The Late Shipment Rate only applies to seller-fulfilled orders — orders where you as the seller are responsible for picking packing and dispatching the product to the customer yourself. For orders fulfilled through Amazon FBA Amazon confirms shipment automatically when the order leaves their fulfilment centre and this process is entirely within Amazon’s control. Because FBA shipments are never late in the seller-confirmed sense a pure FBA seller operating zero merchant-fulfilled listings will almost always have an LSR of exactly zero.

The LSR becomes a real concern for FBA wholesale sellers in three specific situations:

Situation	Why LSR Becomes a Risk
Running merchant-fulfilled listings alongside FBA	Any merchant-fulfilled order not shipped on time counts toward LSR — even if your FBA orders are always on time
FBA stock running out — temporarily switching to merchant-fulfilled	During a stockout period if you fulfil orders manually rather than suppressing the listing dispatch standards must be maintained
Stranded FBA inventory forcing orders to merchant-fulfilled	Stranded inventory in FBA cannot be fulfilled — if the listing remains active orders arrive as merchant-fulfilled creating LSR risk

How to Check Your Late Shipment Rate in Seller Central

Your LSR is displayed in the Customer Service Performance section of your Account Health dashboard. Here is exactly how to find and interpret the data:

The Most Common Causes of Late Shipments for Wholesale Sellers

Cause of Late Shipment	What Happened	Prevention
Forgot to confirm shipment in Seller Central	Order dispatched on time physically but shipment confirmation not submitted in Seller Central before deadline	Confirm shipment in Seller Central immediately after physically dispatching — never leave confirmation for later
Out of stock — order accepted but no stock available	Listing remained active during a stockout — order placed by customer — seller unable to fulfil on time	Suppress merchant-fulfilled listings immediately when stock runs out — never accept orders you cannot fulfil on time
Courier collection not booked on time	Seller did not book courier collection promptly — missed collection window — order dispatched the following day	Book courier same day order is received — have a standing daily collection arrangement with your courier where possible
Handling time setting too short for your actual process	Seller set 0 or 1 day handling time but prep and packing takes longer — orders consistently missed expected ship date	Set your handling time in Seller Central to match your actual prep time — 1 to 2 days is realistic for most sellers
Bank holiday or weekend not accounted for	Order placed on Friday or before bank holiday — seller did not adjust handling time or dispatch process	Configure your merchant-fulfilled listings to exclude non-working days from handling time — update holiday handling settings before all bank holidays

How to Fix an Elevated Late Shipment Rate

If your LSR is above 2 percent or trending upward you need to act immediately. Here is the priority action sequence:

Setting Your Handling Time Correctly in Seller Central

Your handling time setting directly determines the expected ship date shown on every merchant-fulfilled order — which in turn determines what counts as a late shipment. Getting this right is one of the most impactful single changes you can make to prevent future LSR issues:

Handling Time Setting	Best For	LSR Risk
0 days — same day dispatch	Sellers with pre-packed stock and same-day courier collection — very fast operation only	High — any delay causes immediate late
1 day — next business day dispatch	Sellers who prep and dispatch the day after order is received — standard for most small operations	Moderate — manageable with reliable process
2 days — two business day dispatch	Sellers who need more prep time — products requiring careful packing or custom preparation	Low — comfortable buffer for most sellers
3 or more days	Large or complex items — bespoke or made-to-order products — slow dispatch capability	Very low — but reduces listing competitiveness

Managing Holiday and Weekend Handling Time

One of the most common causes of unexpected LSR spikes for merchant-fulfilled sellers is bank holidays and weekends where orders are placed with a short expected ship date that falls on a non-working day. Seller Central allows you to configure your working days and holiday settings to ensure handling time calculations exclude non-working days. Here is what to configure:

Setting	Where to Configure	What to Set
Working days	Settings — Shipping Settings — General Shipping Settings	Select only the days you actually dispatch — Monday to Friday for most sellers
Holiday periods	Settings — Shipping Settings — Holiday Settings	Enter any periods you will not be dispatching — bank holidays — personal holidays — business closures
Vacation mode	Account — Account Info — Listing Status	Set listings to Inactive for any period where you cannot dispatch — prevents orders accumulating during absence

The LSR Protection Checklist for FBA Sellers With Merchant-Fulfilled Listings

LSR confirmed below 4% in both 10-day and 30-day windows	☐
Handling time set correctly for all merchant-fulfilled listings	☐
Working days configured in Shipping Settings — non-working days excluded	☐
Manage Orders checked daily — all merchant-fulfilled orders with ship date today dispatched and confirmed	☐
Shipment confirmation submitted in Seller Central immediately after physical dispatch — not deferred	☐
Merchant-fulfilled listings suppressed immediately when stock runs out	☐
Holiday settings updated before every bank holiday or business closure	☐
High-volume or difficult-to-dispatch ASINs converted to FBA where possible	☐
All LSR checks confirmed — late shipment rate protected	✅ Clear

Conclusion — Pure FBA Is the Ultimate LSR Protection

The Late Shipment Rate is one of the simplest account health metrics to manage for FBA sellers — because FBA eliminates the metric entirely for every product it fulfils. For wholesale FBA sellers who operate exclusively through FBA the LSR is a background metric that rarely requires active management. For those with merchant-fulfilled listings running alongside FBA the answer is equally clear — maintain correct handling time settings check your Manage Orders page daily confirm every shipment immediately after dispatch and convert any consistently problematic merchant-fulfilled listings to FBA as quickly as your inventory process allows. An LSR of zero is achievable for every FBA seller and every FBA seller should aim for exactly that.
