Currently, the NSE estimate system adjusts the margin percentage automatically based on a couple of different things. 1. The price set of the product in Products & Services. 2. The markup percentage on that product, even though it's set to only go off of Margin. This will throw off the margin and even go below the set margin minimum, which can lead to loss of business if not noticed, and the estimate is sent off without notice. Having set up warnings of adjusting prices and how it will affect the margin calculations, or making it more obvious what the margin calculator calculates off of, will help prevent this issue.
