As to the Tenant's responsibility, that becomes a charge against the Tenant, assuming you invoice them prior to sale completion.

Be sure the tech includes notes on invoice.

Then a few days before Christmas 2022, we get an email with an invoice for an additional 18,000 for projects he was never asked to do and or did not complete in the previous months.

Not sure if this is an invoice for work done or an estimate for work to be done. 

Many require actual invoices or written estimates from a third party.

This can be done right along with your invoice process or receipt generation to kill two birds with one stone.

You work on draws, submit invoices, work gets inspected.....SOP for most legit contractors.

The premise sounds all great and all but it all assumes they have you have sufficient positive cashflow to constantly keeping your daily balances low (rents/invoices/receipts/etc coming in through out the month).How has your experience with the strategy been?

If it is a mostly cash business, maybe review and cross-reference the supplier/distributor invoices they have to see how much they are purchasing (this does not guarantee that it is actually being sold at the store though).

Primarily what I am looking for is:- Full integration with AirBnb, VRBO, booking.com, and other booking sites - calendar, messages in one place, bookings, etc- Personal website creation is a plus- issue payments & bookkeeping- issue invoices when neededI was looking into Guesty - any experience there?
