Would you rather get a invoice for the hours worked plus materials or receive a quote per job or any other way that I'm unaware of? 

If the city doesn't allow the tenant to put utilities in their name (for example, my Cleveland, OH tenants can't put the water bill in their name because it stays with the property), I invoice them and attach the bill so they know they're being charged for their usage.

I use QBO, so I just log on my cell phone, because I can snap a picture of the physical receipt or invoice to be saved with the record online, and then I can throw it away.Acquisitions: I am not actively trying to grow my portfolio, but I do have alerts setup through the MLS that give me emails everyday. 

Dang @Jim K., thanks for the education on masks!

But our leases state the tenant is responsible for all utilities so we simply forward them a copy of the invoice so they can reimburse us. 

I found this contractor online, and we agreed upon a full remodel price via email – we never signed any contract – the work was completed, but he came back almost two months after the work was done with a new invoice showing a 30% increase in cost.

I personally like to break out my invoices accordingly - IE prior year billing adjusted for inflation, and then separate line items for anything new over the prior year - accounting for a numerous refi, new properties, significant bookkeeping required, cost seg, etc. 

Dang - Sounds like this one is a mess.
