I operate in Guyana. I recently purchased Quickbooks Online Plus (US).

I have not turned on the multicurrency feature but a check shows the home currency as US$ although the feature has not been turned on. Further I have created invoices using US dollar amounts.  

I need to have Guyana dollars as the Home Cuirrency. 

What must I do to have my home Currency as G$ and can I now go and change the invoice amounts to Guyana dollars  and how is that done.
