Do you supply a VAT invoice?
Yes. The invoice is automatically generated as soon as you make payment and it is emailed to the email address used on your account. If it does not arrive (attachment to email) then check your spam / junk folders. If it is still not there then maybe your company has an overriding spam filter so ask your tech department.
Also, and probably easier than asking you techincal department , you can log in to your account at any time and download from there
