FAQs
1. What does VAT exclusive pricing mean?
VAT exclusive pricing means the listed unit price does not include tax. The calculator adds VAT after discounts and shows the final gross amount separately.
2. What does VAT inclusive pricing mean?
VAT inclusive pricing means the entered amount already contains tax. The calculator extracts the taxable net and VAT portion from the gross price.
3. Are shipping and other charges taxed here?
Yes. Shipping and other charges follow the same VAT mode and rate selected in the form. That keeps the invoice treatment consistent.
4. Can I apply both line discounts and invoice discounts?
Yes. The calculator first applies each line discount, then applies the invoice-level discount to the combined taxable net of all line items.
5. Why is rounding adjustment available?
Rounding adjustment helps match accounting practice, printed invoice rules, or payment gateway totals when a minor upward or downward correction is needed.
6. Does this tool create a legal invoice document?
It calculates invoice values and provides exportable summaries. You should still check local invoicing rules, numbering requirements, and required legal fields.
7. When should I use a fixed invoice discount?
Use a fixed discount when you want to subtract a specific amount from the taxable base, regardless of invoice size or product mix.
8. What does the chart display?
The chart compares taxable net, VAT amount, and grand total. It gives a quick visual view of the tax share within the invoice.
