What happens if my invoice shows incorrect organisation details ex: Name, Address etc?

You can fix the errors in your last posted invoice via the billing page. Please click on 'Incorrect invoice?' link next to the invoice, and amend the details on 'Bill To Address', 'Sold To Address' or 'VAT/GST'. Once the details are updated, click on 'Regenerate Invoice'. The regenerated invoice will be emailed to you in few mins. Please note that only the last invoice can be edited within 15 days of it being posted.
