- Discounts are reductions in the invoice amount offered to encourage prompt payment or as part of promotional offers.
- Surcharges are additional charges added to the invoice amount, often to cover specific costs or circumstances.
Percentage charges are calculated based on the total invoice amount, while fixed amount charges remain constant regardless of the invoice total.
For instance, a user might apply a 10% service fee on an invoice, or they might apply a flat $50 delivery charge.
Taxable charges are those that are subject to applicable taxes, such as sales tax, value-added tax (VAT), or goods and services tax (GST), depending on the jurisdiction and the nature of the transaction.
Non-taxable charges, on the other hand, are not subject to taxes and are usually exempt from tax calculations.
