If you provide us your VAT number, we're happy to add it to your profile in our billing system.  It should then show up on future invoices.

As for our relationship with VAT:  as a US-based company with no European subsidiaries or physical presence, Haiku Systems Inc. is not registered for VAT and does not have a VAT number.  No VAT is included in Amount Due on invoices issued by Haiku Systems Inc. Any applicable VAT is to be reversed charged to the Customer.
