Thanks Joey but the business is does not have multiple employing entities it only has one, so your explanation cannot be the reason. I have setup STP okay and is working. I think the branch number relates to the Business Activity Statement. The normal BAS has a number 001, we also lodge CAS (Consolidated Activity Statement) which as a number 002. With other entities using Xero I had to add the 002 as the Branch number but I cannot find where you can do this in QB. There is nothing in settings. Please see attached screen shots., Thanks Andrea
