Why is your address required, but not your telephone number? Once you have completed our quote form, we will have all the information we need to make a quote, and we do not wish to bother you by telephone. Of course, if you want us to call you, we will be happy to do so. The fact that we are asking your address here makes converting the quote into an order later on a one-click process that requires no further invoicing information, saving you time. In addition, all European customers must provide accurate VAT information for an accurate price quote. VAT numbers always start with a specific country code, followed by up to 12 alphanumeric characters or capitals (without full stops or spaces).
