Hi Charies,

I am facing the same problem as dougpee. 

If we add Tax Number under Customer Information, that's for customer only. Where can we show our company Tax Number on the invoice. I can see a Sales Tax Registration Number field in Company section under Account and Settings. I have put in my TRN there but QBO invoice is not showing it. It shows the Customer TRN but it won't show mine. There's no custom-field option available at invoice-header-level also.

Thanks.
