We are buying ALL our UK postage labels from Amazon using Evri.

What we are seeing is postage label charge being added by evri who are sayin that we used wrong dimensions and weight for every order we have sent. This is completley wrong because we measure every single package and weigh them correctly and then enter all the required information before purchasing shipping labels. We are NOT cheating the system and why would be???

We sell Martial Arts uniforms and each item is correctly measured and weighed before sending so how can EVRi come to this conclusion that we are not??

Has anyone else faced this same situation and how best to go about getting this resolved?

Our account has gone into negative despite we are making sales on a daily basis.

Hi everyone,

This evening, we’ve been hit with hundreds of sudden charges on our account under the description:

"Carrier delivery label adjustment due to under-charged delivery label"

These adjustments are:

Hitting all at once with no prior notice

Going as far back as April 2025

All related to EVRi Seller Fulfilled Prime (SFP) shipments

Providing no clear breakdown or calculation of how the so-called "undercharge" was determined. All we can see is that its a duplicate charge to the original buy shipping charge.

This has caused massive billing disruptions and we're concerned it may be a system-wide issue or billing error. A few example order IDs show the same problem with duplicate or unexpected label charges retroactively applied.

We have raised this with both EVRi and Amazon support, but are still waiting for an explanation or fix.

Is anyone else seeing this?

Would appreciate hearing from other SFP sellers (especially those using EVRi) to understand if this is isolated or affecting others too.

Thanks in advance for any insight!

A case has already been opened about the issue, I am posting this here to hopefully raise awareness of the issue...

My account has been billed multiple adjusted charges for many of my sold items where postage was bought via Amazon, with Evri being the courier.

The adjustments are claiming that the original label cost of 2.95 for instance was undercharged, the result is a doubling of the postage fee and £100s of lost revenue.

All items are weighed and measured correctly so what is going on here? A system glitch? Evri trying to pull a fast one?

There is no way in hell that a small item, weighing 200g, measuring 30x 10 cm costs £6+ to send.

Has anyone else experienced this issue? It's causing me alot of stress it has to be said.

Hi all,

I’m hoping someone else has come across this — I’m seeing repeated £2.50 “Carrier Delivery Label Adjustment” charges from Amazon on shipments sent via EVRi using Buy Shipping, where:

The item is under 1kg

I’ve entered valid dimensions and weight

The carrier-audited values match exactly

I’ve already been charged for the label (typically £3.00)

Example:

For one order, I declared the parcel as 45 × 35 × 16 cm, 1000g.

The actual item was much smaller (522g, 14 × 2.6 × 21 cm), but I over-declared to be safe.

Amazon charged £3.00 for the label — then later hit me with a £2.50 surcharge, citing “Carrier delivery label adjustment due to under-charged delivery label.”

This is now happening across dozens of orders, and after reviewing just a week’s data, I’m already seeing £500+ in unexplained extra charges.

It seems to happen specifically when using EVRi through Buy Shipping, and even when all the entered and audited data match.

Has anyone else experienced this?

I've raised a case with Amazon, but would love to hear from others before escalating.

Any experiences or advice appreciated.

Thanks,
