You can save a VAT ID in the contact details of your profile on the website or in the apps. You can add the VAT ID after your company name e.g. Blacklane GmbH (VAT ID: 123456789), and it will appear like that on the invoices for any bookings thereafter.
To add a PO number to a booking, please enter it in the “Reference code”/”Reference number” field when booking.
If you you need to add either to an invoice that has already been generated, please contact our Customer Care Team.
