Thanks for the great suggestions, @Pipe3001.

 Our goal is to make QuickBooks as user friendly as possible and a one-stop shop for all small business owners like you.

With QuickBooks Online, you have the ability to customize your invoice form which include adding the names of your Sales Representative. 

Here's how:

1. Go to the Gear icon.
2. Choose Accounts and Settings.
3. Select Sales.
4. Under Sales from content tab, click Custom Fields.
5. Type in the name Sales Rep on the first box..
6. Put a check mark on Internal and Public.
7. Click Save.
8. Hit Done.

Once completed, you can now add the name of the sales rep everytime you create an invoice, sales receipt, estimate and credit memo.

To run a report show sales per representative, here's how:

1. Go to Reports.
2. Choose Sales by Class Detail.
3. Under group by, choose Sales Rep.
4. Click Run Report.

You also have the ability to change the name of the report from Sales by class detail to Sales by Sales Representative.

On the other hand, Profit and Loss is a type of report that shows a detailed view of your income, expenses, and net income (profit or loss). Shows individual transactions. On the P&L the number in COGS is displayed as positive ( debit) the P&L does not show debits and credits unless you drill down. In cash basis reporting for sales, COGS is only posted when the sale is paid.

Lastly, feel free to send your suggestions for improvement  and I'll do the same thing from my end.
