Tell him to stop work, and give you an invoice for work performed up to that point.

I can share invoices and other details if you're trying to put a project together. 

I do the raw data entry as it's just dumb to hire someone to do that and then pass it on to the CPA.So I enter bills, payments, po's, invoices and payments, but that's it. 

It does not work with quickbooks either so you need to PDF an invoice an attach it if you use one.  

I just took a online payment from my QBO invoicing system today.

Also, it is clear that Quickbooks really is trying to build a product to sell add on features like payroll and invoice processing. 

Lender wants buyer to show paid invoices BEFORE closing, and to then disburse the funds to the buyer3.

Do exactly what you have laid out...let him know that you are serious, have him stop work, and invoice for work completed to date. 

Some mark up maintenance invoices.

Plus what was already mentioned, this way you can verify (with paid invoices & lien releases signed as proof) that each contractor was paid as agreed, in writing to help alleviate any mechanic's liens (I have stories about those too).
