I actually scan all HUDs, checks, documents, receipts etc because they can be lost or fade.He started by explaining the process.

I'd make them pick it up and sign a receipt/release for it to cover yourself. 

On the receipt it's called a "CUTTING, HRZNTL."

Some property-management apps have Xero/QuickBooks integration so you can sync all transactions, suppliers, tenants, upload receipts, etc. 

The least trivial part of the Certificate is a Fire Marshall inspection and most of the rest is paperwork like business tax receipt, articles of incorporation for your LLC, copy of the lease, etc. 

I always contact the wire recipient upon sending, and ask them to notify me upon receipt, this wasn't enough.By the time everyone realized something was weird and everyones stories didn't add up, it was 8 hours after the wire was sent.

Also does anyone use a receipt scanning service? 

You'd have to issue receipts to everybody for records purposes, and you are absolutely setting yourself up to be robbed if your routine is carrying around large amounts of cash on the 1st of every month.
