Custom Template

Iv filled my details in and entered a mobile number and website address but does not display on the quote or invoice, I would also like to put the postcode on the line below Bridlington. Where do I find and edit the files. This is what it looks like:

Home Improvements
XX The Crayke
Bridlington YO16 XXX
East Yorkshire
United Kingdom

P: 01262 XXXXXX

Many Thanks

You find a lot of information about templates and on how to customize them in the wiki:

Are the invoice and quote in
The same or is they a slight different between the two? As in the coding.

No they are not the same. Invoices and quotes do not have the same codebase.

Ok, Thank you.
