A way to implement a “hidden” percentage-based fee that automatically increases the manually entered item prices by X%, without displaying it as a separate charge. Different from the garment markup matrix, as sometimes clients get special pricing and all item costs are entered manually.

Ideally, this would also include a “refresh” or recalculation button so that if items, quantities, or sizes are adjusted after the quote is created, the X% is automatically reapplied and updated across the entire quote.
