title: QuickBooks rounding issue
body: <p>We are primarily Sage developers and I have been able to achieve this in Sage. Now I need the same functionality in QB and we are struggling. The problem is a rounding issue. We have a spreadsheet with Gross (total) invoice amount. We take that data, calculate NET and VAT and post it to QB 2014 using SDK v13. But we have a problem when for example the total is £123.45, the NET (before tax) should be £102.88 and the VAT (tax) should be £20.57, but QB is calculating VAT at 20% as £20.58 giving us a total of £123.46, which is incorrect in terms of what we want the value to be.</p>
  
  <p>We are using IInvoiceAdd and IORInvoiceLineAdd in order to add invoice into QB. How can we achieve the above and tell QB that the total VAT is £20.57 and not £20.58, by keeping the accountants happy? Any adjustment to NET or adding adjustment item or doing journal entries are work-arounds rather than a fix, we want to know if this is possible as we did in Sage. We are able to do this via the UI in QB, so is there a code equivalence to do this.</p>
