Is it possible to display an alternate company (site) address on a customer invoice without creating a separate company

Hi Ando2924, 

Thank you for sharing your concern with us. Apologies for the delayed response.

I understand that your specific needs require you to change your address based on the site associated with an invoice. The address displayed on invoices is derived from the address saved under Setup > Company Information. Regrettably, our system only permits one address to be saved per file.

However, there's a workaround for this. You can create duplicate copies of the invoice and instead of using the [Company Address], you can add a Text box and input the corresponding address for each invoice form. 

Let us know if you require any further assistance. 

Thanks,
