I paid the invoice with my credit card.To make sure I was getting quoted a decent deal 2 other companies come out the next day. 

I asked to see invoices and he refused.

**NEVER PAY A SUB 50% upfront**1st Always have a proposal from the esteemed subcontractor it vendor, with their information - qualify the sub no matter how big or small the job is:• look up their State License on your state license board - make sure it’s active, not suspended • Let them send in their insurance information with your property as the additionally insured • keep track of any Preliminary notices that they may send to you 2nd Come to a written agreement/contract of a payment schedule* - with less 5% retention on each invoice until close of project scope A timing schedule is also really good to have in your contract that way they are not just prolonging the job.

It is common for vendors to invoice us 2-4 weeks after work and then we issue payment in roughly 2 weeks turnaround so most of our bills don't process through to owner statements for 30-60 days.

I made sure each had some sort of property software that documented everything for me (checks, invoices, etc).

Any software recommendations to keep track of invoices, rent receipts, financial statements, etc.?

One of the requests was that I get an official invoice for any outstanding balance for each property.

Please let me know if you're interested and we can do Venmo or I can send a Quickbooks Invoice.

I had asked this question on the Facebook fan page and got banned lolwho do you use for invoicing tenants? 

But after I notified them that I would be switching over to another management company I was suddenly hit with a charge of over 400$ for "Additional Repair Work" without a breakdown of how this charge came to be and without an Invoice.
