See a shipping metric slipping days before the marketplace acts
Metric Lookout reads your shipping metrics on Amazon, eBay and Walmart, every day where the marketplace lets us connect read-only and on each report upload otherwise, compares them with each marketplace's published limit, and tells you which orders are pulling the rate down. Each marketplace measures late shipment, tracking and on-time delivery differently, over different windows, and we track each one on its own terms.
Updated
- Thresholds checked against each marketplace's own policy page: Amazon late shipment under 4%, valid tracking above 95%, on-time delivery at least 90%; Walmart valid tracking 99% or above; eBay tracking on 95% of transactions for Top Rated.
- An alert when a rate comes within a margin you set of its limit, with the order IDs behind it: confirmed after the ship-by date, tracking uploaded after delivery, carrier name not recognised, or no carrier scan.
- Read-only data from the performance reports you download or, where the marketplace has approved our app, its reporting API; we never ask for your login password.
Amazon's Order Performance policy asks for a late shipment rate under 4% (10 and 30 day windows), a valid tracking rate above 95% over 30 days, a pre-fulfillment cancellation rate under 2.5% over 7 days, and, since 25 September 2024, an on-time delivery rate of at least 90% for seller-fulfilled products (checked 7 November 2026).

A seller who ships its own orders to Amazon, eBay and Walmart buyers works under three sets of shipping rules at once. Amazon measures late shipment over 10 and 30 days and valid tracking over 30 days. Walmart evaluates over 30 or 60 days and wants 99% valid tracking. eBay evaluates on the 20th of each month and looks back three or twelve months depending on your volume. The same late afternoon at the packing bench lands differently in each dashboard.
Nobody on a small team opens three dashboards every morning, so problems are usually found when a marketplace sends a warning. By then the rate reflects weeks of orders, and fixing it means shipping cleanly for weeks more. The causes are often mechanical: a carrier name typed differently from the drop-down list, tracking added after delivery, a handling time that no longer matches how fast you really ship.
The cost of missing it is high. Amazon says a late shipment rate above 4% may lead to suspension of seller-fulfilled selling privileges. Walmart says missing its standards may result in suppression, suspension or termination. eBay sellers who drop to Below Standard can see lower search placement, held funds and higher final value fees.

With Metric Lookout
- Thresholds checked against each marketplace's own policy page: Amazon late shipment under 4%, valid tracking above 95%, on-time delivery at least 90%; Walmart valid tracking 99% or above; eBay tracking on 95% of transactions for Top Rated.
- An alert when a rate comes within a margin you set of its limit, with the order IDs behind it: confirmed after the ship-by date, tracking uploaded after delivery, carrier name not recognised, or no carrier scan.
- Read-only data from the performance reports you download or, where the marketplace has approved our app, its reporting API; we never ask for your login password.
- Per-marketplace windows
- Warning margin you set
How it works
- 1
First check
Once you choose a plan, you send this month's performance downloads from each marketplace. Within 2 business days we show where each metric stands against its limit and which orders drive it.
- 2
Connect read-only data
Where our app is approved for a marketplace, you authorise read-only API access; otherwise you send the performance downloads on a schedule we agree. Setup takes up to 3 business days.
- 3
Checks and alerts
We recalculate every metric in its own window, daily with API access or on each upload if you send files, and alert you by email or Slack when one crosses the warning margin you chose, for example Amazon late shipment above 3%.
- 4
Causes and fixes
Each alert lists the orders behind it and the likely cause, such as a carrier name mismatch or a SKU whose handling time is set too long, and a weekly summary shows the trend.
Features
Per-marketplace windows
Amazon's 10 and 30 day late shipment windows, Walmart's 30 and 60 day standards and eBay's 3 or 12 month evaluation are each tracked separately, so a good week on one does not hide a bad month on another.
Warning margin you set
Alerts fire at a margin you choose below each limit, not at the limit itself. Default margins are one point for late shipment and cancellations and two points for tracking.
Order-level causes
Late confirmations, tracking uploaded after delivery, unrecognised carrier names, missing carrier scans and late hand-over are listed per order, with the order ID you can open in Seller Center.
Handling-time check
Compares the handling time set on each Amazon SKU with how fast it actually ships, so you can adjust it before Amazon flags it under its handling time requirement.
eBay evaluation countdown
Shows where you stand before the next evaluation on the 20th, including the projected seller level from eBay's own projected cycle.
Weekly summary
One email each Monday with every metric for every marketplace, the change since last week, and the three fixes that would move the numbers most.
Multiple accounts
On the Agency plan, several seller accounts in one view, with alerts routed to the person responsible for each.

Who it's for
Multichannel sellers shipping their own orders
Brands and resellers fulfilling Amazon, eBay and Walmart orders from one warehouse or garage, who need one place to see all three sets of shipping metrics.
Sellers recovering from a warning
Accounts that have just received a performance notification and need to know, day by day, whether the rate is moving back under the limit.
Agencies and small 3PLs
Teams that ship for several marketplace sellers and want to catch a client's slipping metric before the client hears about it from the marketplace.

- An Amazon tool that lists daily account health monitoring in its Growth plan at $149 per brand per month (14-day trial). Its pricing page mentions only Amazon, not eBay or Walmart.
- SellerEngine account monitoring

- Since 29 June 2026, Amazon requires accurate handling times on seller-fulfilled SKUs; if you consistently ship at least a day faster than the set handling time, the SKU shows as non-compliant, and if it is not fixed within 30 days Amazon adjusts it for you for 180 days (checked 7 November 2026).

Walmart Marketplace performance standards as of November 2026: valid tracking 99%, on-time delivery 90%, late shipment 5%, and how eBay's standards compare.
Read the guide →Questions
Which metrics do you track?
On Amazon: late shipment, valid tracking, on-time delivery and pre-fulfillment cancellation, plus order defect rate. On Walmart: cancellation, on-time delivery, valid tracking and late shipment, plus the other published standards. On eBay: late shipment rate, tracking uploaded and validated, transaction defect rate and cases closed without seller resolution.
Do you need my Seller Central or Seller Center password?
No. You send the performance report downloads, or, where our app is approved for that marketplace, you authorise read-only API access, which you can revoke at any time from the marketplace.
I use FBA or WFS. Is this useful?
Only for orders you ship yourself. Amazon applies late shipment, tracking and on-time delivery to seller-fulfilled orders, and Walmart says WFS meets most performance metrics for you. If all your orders go through FBA or WFS, tell us before you choose a plan: we will say by email whether there is enough to watch.
How fast will I hear about a problem?
With API access, metrics are recalculated once a day, so an alert usually reaches you the morning after the orders that caused it; if you send files, we recalculate on each upload. The marketplaces themselves can take up to a few days to reflect tracking edits; Amazon says to allow 72 hours.
Can you get my account reinstated?
No. Metric Lookout is monitoring, not an appeal service. If you are already suspended, use the appeal path in Seller Central or Seller Center; our order-level data can support it.
Is Metric Lookout affiliated with Amazon, eBay or Walmart?
No. It is an independent service. The thresholds we use are the ones each marketplace publishes, and the marketplace's own dashboard is always the final word.
