Dynamic Margin is an item setting that allows cost to be calculated as a percentage of final sale price. This is particularly useful for consignment merchandise or items where you have enabled the setting Prompt for Price.
Enabling Dynamic Margin
To enable Dynamic Margin, click to the Options tab in any item record and set Calculate Margin Dynamically Based on Percentage to Yes.
Setting An Item's Dynamic Margin
Once you have enabled Dynamic Margins, you will see the Dynamic Margin field appear in the item record where Default Cost previously appeared. Enter the margin percentage for the item in this field. The item's cost will be calculated based on its final sale price. As you sell this SKU, you will see the Average Cost in the item record update to reflect sales.
