Hi MaryAnn_E

Thanks for the explanation.

In QB I set USD as a home currency, when I create a new customer I also choose USD , then when I make an inovice it gives me the error. But when I choose IQD no error appears, however, all my products are intered in USD, so the calculation all becomes wrong actually when I choose IQD. 

I have followed the steps in this articel Clear cache and cookies to fix issues when using QuickBooks Online.. 

if possible to solve it for me remotely using team viewer or any other application would be great.

Many thanks
