The ability to remove both of these columns needs to be a priority for the Quickbooks Team. 

Being able to hide the column for the client ONLY is unacceptable. It is the billing department that is suffering from missing line items that should have been billed but weren't because they did not fall under the amount column that sums up the total but the HIDDEN rate column instead that does not end up in the billing total. 

Placing a number under the rate column does not always automatically enter it under the amount column which is absolutely detrimental for billing.

It's been TWO YEARS since someone raised concerns about this and NOTHING has been done. 

This is a very important customizable feature that would help a lot of business owners if it was fixed.
