I import corporate credit card transactions into NetSuite and generate employee expense reports, enabling users to upload receipts and assign expense categories. The imported transaction amounts already include sales tax. However, when users select a tax code, NetSuite applies the sales tax on top of the imported amount, resulting in duplication.

Is there a way to configure NetSuite so that it recognizes the tax as already included in the total, while still properly accounting for it? Additionally, is there a more efficient method for reconciling credit card transactions and collecting receipts from users?
