How can I write off two invoices that customers will not pay? From what I'm seeing I have to ask my accountant to do it and I don't really want to pay $$$ for that.

It seems you can either create credit memos as a 'return' of the sales or void the original invoices if they turned out to not represent a real/final sale.

Why would you need an accountant to do that?

It is for a service we provide. They changed ownership and will not pay. I don't want to void the invoice because it cost me $ to provide service. I am thinking it needs to be attributed to bad debt. When I look at how to do that, it says it requires the "Accountant Toolbox" 

Sorry I don't know why you'd need an accountant to write off an invoice. Nothing like that is required when using QB Desktop.

What if you try receiving a customer payment, potentially against the invoice, and then instead enter a discount for the entire amount of the invoice?  That seems like one way to write it off.
