Ounce Taxes (Custom Taxes by Destination)

Order Entry

Automatically calculates and adds an additional tax (e.g. a Sugar Tax) to items in O/E Orders, Shipments, and Credit/Debit Notes when they are of a particular item category and destined for a particular postal code, city, or state.

The tax is calculated based on a non-stocking Unit of Measure for the I/C item.

Although this customization was originally built to cater for fizzy drinks taxes in US cities, it is easily adapted to any tax that applies only in certain locations, or that is calculated using a non-stocking UoM.
