Opencart Company and VAT registration numbers added to invoice

The default invoice in Opencart 1.5.5.1does not record the company name, registered address, registered number and place of registration nor the VAT registration number.

A "quick and dirty" fix for this is to hard code the information into the file admin/view/template/sale/order_invoice.tpl as follows: 

immediately before the last </div> line in the file (four lines from the bottom) insert a line reading

<small><?php echo "[xxx]"; ?></small>

where [xxx] is the company and VAT related disclosures you wish to have on the bottom of your invoices.

It may not be pretty but it costs nothing and it works.
