Hello @Seller_X3j2mUacSC9s6,

Thank you for reaching out on the forums.

We received a warning from Amazon because our on-time delivery rate is only 36.03%. This is surprising to us because we have been in business for 2 years and our on-time delivery rate has consistently been above 99%.

I see that recently your OTDR (on time delivery rate) metric has been impacted and you would like some information about why this could be happening.

There has been a policy update in 2024 for this performance metric. You can find this information in the following help page:

--Changes to program policies

I strongly suggest that you review the OTDR FAQ resource for the tools needed to ensure your OTDR metric stays healthy.

--Frequently asked questions about on-time delivery rate (OTDR)

Here is very important and helpful information from the above policy page for you to review:

You can manage your delivery dates using the tools we’ve provided, or you can manually adjust your Transit time and Handling time settings. We designed these tools to set accurate delivery dates, reduce late deliveries, and to meet or exceed the minimum OTDR requirement. And because Amazon is making calculations on your behalf that affect OTDR, you'll get OTDR protection from late deliveries on units shipped through standard shipping if you use all three tools as follows:

-Shipping Settings Automation (SSA), for Professional selling plans, sets accurate delivery dates through automated transit time calculations of your preferred shipping services. You must choose one of the preferred ship methods in the SSA templates, which will mark the transit time on the shipping template as "Managed by Amazon".

-Automated handling time, for Professional selling plans, sets accurate handling times per SKU based on how long it usually takes you to pass each SKU to carriers. You must ensure that automated handling time is enabled in your shipping settings.

-Amazon Buy Shipping, for both Professional and Individual selling plans, sells shipping labels that use highly-reliable ship methods. You can use Amazon Buy Shipping through Manage Orders, Shipping API, Veeqo, or select multi-channel integrators with access to Amazon Buy Shipping. You must choose shipping labels marked as “OTDR Protected” when using Amazon Buy Shipping or Veeqo.

Once you have reviewed this information, please let me know if you have these features enabled. If you have any other questions please don't hesitate to reach back out. The forums community and I are here to support you.

Wishing you the best,
