Hi adamk,
look for your E-Mail back in the past. After your Order you got one E-Mail with the total amount and the Bank Code Number. And days later you got a E-Mail like “Your Purism order receipt from …”
This should be enough proof of payment.
Regards
Christal
My email address and credit card have changed over the last 4 years! I found a screenshot of the order process in 2019 and forwarded it also to customs.
support helped me by sending me the same documents that where rejected by customs.
i am in contact with support Mladen Pejaković.

uhhh,
i have found the word “WIRECARD” in your attached documents.
i checked address confirmation mail and company is Wirecard. i over-
viewed it!i was employed by Wirecard and used to have my shipment there.
after Wirecard’s bankruptcy in 2020 i have changed online billing and
shipping address to my personal address.pls see attachted screenshot
of https://shop.puri.sm/my-account/edit-address/
there is no wirecard since 2020!i think wirecard has triggered the authorities!
please send my a personal invoice, not a commercial/businesses, one!
no response so far!
@adamk I had the same issue as you, but fortunately, my previous bank sent me via email my account activity reports as a PDF every month, so I found the report from month when I purchased Librem 5 and used that as a payment proof for customs.
Do you have something like that maybe?
My turn!

OMG, I’m July 31st '19: so close I can practically taste the icing off the top!
Encore un effort, Purism: let’s go with that shipping email!
They haven’t told you what issue exactly they’re having with the enclosed invoice.
Customs officials are people, too. Sometimes they make mistakes but whenever I had an issue, they were happy to help.
Once, they even accepted a printout of a year-old SMS thread I handed them as proof of purchase!
I’m sure you’ll be absolutely fine. There’s no reason to be afraid.
Anybody else received L5 with accessories(includes battery)?

@narezina Actually, it was “only” an upgrade to Visa Gold that came with a new account number. The issuing institute remained the same. Should be possible to receive past reports, of course for a fee. Will do that if the evidence presented is not sufficient for customs. i can download reports for the past 3 months what i probably should do!
@Lliure true. should be just a matter of time when i can hold the L5 in my hands. Current case status is: “in progress”. fingers crossed.
Very great day yesterday. Finally received my L5

Librem 5 has currently got a hopeful lead time for delivery (about a year). Meanwhile some Librems start resurfacing on ebay and the like, certainly a faster way to get hold of this device!
