When you are manually creating a new sales order for a regular or repeat customer it would be handy to have the ability to quickly & easily see their previous purchase history & price paid for each product as it is added to the order. Our regular good customers receive discounts & it is time consuming to have to search previous sales orders to see what they paid last time.
Our previous software had a button near the product lines of the sales order that you could click to show any previous purchases of that product for that customer, we used this all the time & miss how quick it was to check a customer's previous pricing.
