Consider using the Trade Discount option in your sales orders, for that ‘done and dusted’ approach. Users can set a fixed percentage discount for all lines on the order, by simply keying in the value at the time of order entry, or - by having it linked to the customer directly – having it apply automatically and saving the user some time. Don’t worry – the Trade Discount overrides any line-level Advanced Pricing adjustments that would apply, so there’s no ‘double dipping’ into the discount bucket!
Additionally, this type of discount is instantly seen in the grid and on the sales invoice (R42565), so the customer can see what a great deal they’re getting. The best part? The trade discount can be set to apply on top of a manually-entered price.
