Hello guys,
Recently I have started working with prestashop and I have found a difficulty modifying files of invoice. So the point is that invoice consists of delivery address and billing address. Basically it's the same. But I want that invoice should consist of delivery address (address of the people who buys from me) and the my address (my business local address). Could you please help me changing because I'm really new in prestashop and I'm afraid of messing up my shop. 
Down below I will atach the code of invoice.addresses-tab.tpl
How can I change billing address to my local business address?
