AHT Miscalculation Causes Late Delivery Risk & OTDR Issues

AHT Miscalculation Causes Late Delivery Risk & OTDR Issues

We have seen several posts about AHT and OTDR issues. Today, we got an order with a 1 day handle time. All of our items are set at 2 day handle time at individual level and all are items are AHT. Up until today, all of our orders were following the 2 day handle time using AHT. But today we got an order with 1 day handle time so we investigated and found the following:

Notice the 1 day handle time on the item has an “average actual performance” of shipping in 2.7 days while the other two shown have 2.0 days and 2.3 days.

This error by AHT will cause us to ship late because it is a custom item and can not ship on time with a 1 day handle time. So this order will go out with a Late Delivery Risk … NO PROTECTIONS and will actually ship on the day it is suppose to be delivered by (which is a deliver by date not supported by USPS historical data as it has never made it there in that short of time to this destination region).

@KJ_Amazon … this type of error within the AHT program is what causes sellers to have Late Delivery Risk shipments and a reason sellers take hits on the OTDR metric or take a hit on cancellation if they choose to handle it that way.

Please provide to the appropriate team to investigate. Order # 114-0193707-7369069 will link them to the ASIN involved.

All of our orders ship Amazon Buy Shipping via USPS. This order will ship Monday (Thursday orders of 2 day handle time go out on Mondays as our post office is closed Saturdays and Sundays).

This may be a reason for the uptick in posts on NSFE about having issues with OTDR. We will ship late and accept the Late Delivery Risk and the OTDR hit as it will ship out the day that is the order’s deliver by date.

We see it as another AI failure to compute.

I will never turn on AHT and posts like this just serve to make me smug.

You don’t necessarily have to turn on AHT. We have encountered a handful of orders in the last month where we were required to ship in one day, our default is 2 days and AHT is not enabled.

I get the same thing almost daily and have 2 day set up for everting w no AHT or SSH. At some point after 10pm EST to like 3 am, I’ll get an order that needs to ship the next (or same day did after midnight).

Yep been getting a lot of the 1 day handling time, which because of the time difference actually comes to same day (order placed after 9pm PDT but before 1159 PDT).

On the other side some of my orders now have a 3 day handle time

I agree - and am not particularly encouraged by NR_Amazon’s 070125 reply to your NSFE thread:

We can’t slap our screen hard enough to have an effect on NR_Amazon so we will just have to bite our tongue and ignore his/her answer as if it didn’t exist.

...

And besides … if we did slap it that hard, we would need a new screen and perhaps a new computer …

NR has been accused of being an AI implementation, and/or using such to flesh out their responses (and/or using such to first choose which path to take) more than once since his/her/its 1st appearance.

I’d think that most all of we here already know just how warm the embrace of automated mechanisms by Amazon has been over the last ¼-century, and it of course makes no bones about expanding that via its own home-brewed GenAI/LLM ‘solutions;’ likewise, we’re all probably mostly aware that Amazon has demonstrated a good deal of evidence that the NSFE itself may well have been launched with an element of consideration for easing machine-language-capable read/write functionalities - hence the early crop of ‘numbered’ AHT SMEs. and members of the FMT-CMT whose NSFE profiles featured the “…_CAM” suffix on their handles which quickly faded into oblivion once the seasoned forum users called them out.

That latter consideration surfaced over in the NSFE in a myriad of ways, not the least of which were the slew of “Testing spam” posts made by members of the various Bug Bounty Hunter communities in the later biz quarters of 2023, and the early ones of 2024.

Most of those posters appear to have created a SoA (‘Amazonese’ for “Selling on Amazon” aka 3P Seller aka Seller Central) Account merely for the purpose of gaining access to the ASF (“Amazon Seller Forums”) in its current configuration - but perhaps not all, because:

  1. At least one of those posters has seemingly been identified as a 1P Seller - aka a member of the Vendor Central Program - who continues to have dispensation, from Amazon, in the highly-restricted Digital Software Download Category

  2. At least two of said Bug Bounty Hunter-posters sported - at the time they made the post, and even now - an Amazon-sanctioned image icon on their NSFE profile; one with the “Amazon Smile” (FMT-CMT), and one with the “a” (AHT SME)

Amazon doesn’t seem to be giving up, though; it’s apparently not plowing full-steam ahead, through uncharted waters (a la the RMS Titanic) - but I’d assert that there’s undoubtedly a reason why the latest of the “…_CAM”-suffixed employees has been posting ‘Testing Spam’ to various of the Global ASF Forums since February 2025, as may be seen on Hank_CAM’s NSFE Profile.

Both of these NSFE discussions were posted over the last two hours to the UK Forums (the fundamental foundation of the various Europe Region fora, and of that Global Region’s Hdqtrs infrastructure itself); the first has already been suppressed, on the URI level, as of 2025-07-01T23:09:00Z EDT.

I’m even more perplexed over NR_Amazon’s 070825 reply:

What do you get when you meld pigeonholes, rabbit warrens, gerbil tubes, and sealing wax?

Why, Amazon’s support infrastructure, of course!

AHT is suppose to auto-calculate handle time based on your shipping performance over time. A 2.7 day handle time should calculate to a 2 day AHT (at least it does on the rest of our items). We have all our ASINs set at 2 day handle time at item level. If USPS performed better, we would turn off AHT but for now we want to keep it to get OTDR protection.

That’s great but we do not have this item (or any of our items) set to seller full-filled prime nor do we have any of our items set to one-day or two-day delivery options.

Our reply …

@NR_Amazon

This item has never been assigned to Seller Full-filled Prime and we have never used or set our shipping templates to use one-day or two-day delivery options. We ship USPS and USPS performance does not support either one-day or two day deliveries from our area.

Introduction to automated handling time

If your account has automated handling time enabled, your handling time and order handling capacity is set automatically based on your historic performance for each SKU**.**

img

3.0 day performance being recommended as 1 day and set as 1 day AHT while the very next item is 2.3 day performance being recommended as 2 day and set as 2 day AHT.

This does not follow what is stated by Amazon for AHT on the above link.

Seems like there is a quirk in the code.

Respectfully,

So we were finally able to get NR_Amazon to see the issue …

NR_Amazon’s last reply

We would note that we do not intend to open a seller support case for this. We are going to wait and see if the AHT program will do what it is suppose to do and calibrate off the current performance level.

AHT is all over the place now.

I have an item that normally has a 2 day handle time now extended to 5 days
2 items that have been extended to 3 day handle time
1 item that is 1 day
and 1 order that is same day.

No idea WTF is going on.

Yep

Yep

We now have 2 items that show 1 day handle time and one item 0 day handle time. These are not the same items in our example above. Interestingly, these 3 just popped up today while the other 4 went back to 2 day handle time as they should be.

Like we said before, we are going to ship as 2 day handle time on every order and wait and see how long this madness continues. Our metrics are holding steady so there doesn’t seem to be a fire to put out right now (at least for us). And as we said before … if the metrics start to become an issue, we will switch to manual where we have everything set at 2 day handle time at item level.

is AHT enabled in your account ? I read some recent posts in NSFE that some sellers have same day orders even though AHT is not enabled (SKU level handle time set to 2 days or 1 day).

Do you have a link to point us to?
We have only seen AHT related posts.
Would like to read examples about this happening with non-AHT settings.
