When speaking of sales then first things first.

To make quotes its critical to understand total quote margin % and amount, as well for orders and invoices. Out of the box, how sales person should know if he/she is making profit or selling with too low margin? Base data is existing in the system and its likely very easy to expand this function a bit for next update?

It is simpe development for partner but as we have experienced - such developments crash, are faulty and and are not reliable. Such basic and vital function should be available out of the box.

I use moment to stress out that functions helping company to become more efficient, save time or ake more money should be always prioritized as without money/profit nothing else will exist.
