I am trying to adjust an invoice and send to a customer, however I am getting a pop up saying 'Liability account is required' - All VAT has been allocated? Please help!

Hi Stuart10, 

We are aware of this current issue there is an investigation on this, the engineers are working on a fix. On the invoice where is says amount are and says either inclusive or exclusive of vat if you choice no vat their then save the error wont show, until the issue has been resolved.
