Simply the cost to repair the damage, backed up with the handyman's invoice as part of the move out and security deposit refund flow.

.)- Invoicing a client for upgrades Up until now, I've been operating from Excel, but we're growing to the point where manually entering transactions and categorizing is becoming very tedious.I tried setting up Wave, and while I'm able to live with some of the limitations it has (i.e. subaccounts), I haven't figured out how I can assign budgets to the expense accounts so that I can track progress.  

If I were in that situation, I would handle their deposit according to state law, applying it towards the oldest unpaid charges, and then send them an invoice for the remainder.

I asked if I could prove Year-to-Date earnings with my contracts, invoices, and bank statements, but they said underwriters always fail these exceptions for self-employed. 

But I make sure that I have the following in place from contracts: (1) I get the late fees (2) no upcharged on repairs, (3) i get to see the contractors invoice, (4) i get access to all data. 

The grader's wife sent invoices for progress payments and as I made payments I notice his wife wrote that I owned $5,000 less than I actually owed.

Dang it @Paul Sandhu there is no use telling the best story when you're involved....

One thing that is a little clunky are managing invoices and reimbursements for maintenance.

Dang.
