We have always asked for a bank statement, so we can cross-reference payroll deposits.

A sophisticated investor will also typically ask for the entire claimed track record and then run it through the wringer.

We look at lenders (so long as they lend in the asset class you are considering) as an additional line of due diligence (they deeply care about their money and they are likely more sophisticated than you are).

During 2022 I had multiple meetings with one of their CPA advisors and gave them access to QuickBooks and Payroll platforms.

So it requires more significant or sophisticated value adds.  

$20k for the sophisticated investor class, and then only two passive deals at $50k each .

My guess is they have low level of book keeping sophistication. 

Also, I am connected with a lot of sophisticated investors on Linkedin and I don't want to lose their respect because I am starting to post educational content when I have never done any transactions.What do you think?

There is so much that goes in a business, rental rates, rental tax, inventory,  job costing, payroll, business analytic reports etc, QiuickBooks does handle what I have mentioned here. 

.- bank integration (download transactions) a must- no employees, so don't need payroll- if it'll bill that's awesome.
