If you need an invoice for your booking which holds your company name (and possibly VAT number and company address), this is possible if you have entered your company info in your Gearbooker account (on https://www.gearbooker.com/manage/updatevat) before you have placed and paid for your booking.
You can then download the invoice from the booking detail page which is accessible from https://www.gearbooker.com/order/list.
However, if the booking has already been paid while your company info hasn't been entered in your account, it's not possible to receive an invoice on your company name retroactively. This is due to the VAT/tax regulations.
