Dear Morgan. I have read your reply and found that you may help me with the following challenge:

I have a new account in Qb and just finished the SALES part key in.

And before keying in the COST part, I found that my home currency in USD, but it must be SGD.

So all my costs are in SGD, but sales are in USD. 

To key in - correctly, I must change my HOME CURRENCY to SGD, but to do that, I must RESET my account without wasting all my invoices.

I chatted with support, and they told me that I must export invoices, reset my account > and import invoices back, but I am afraid of losing data, and I need professional help.

CURRENT STATUS:

My home currency USD

My sales are in USD, and my cost in SGD

NEEDED STATUS 

My home currency in SGD

My sales are still in USD, and my cost in SGD
