Formula
Total = (Subtotal - Discount) + Tax | Tax = (Subtotal - Discount) x Tax Rate
Add multiple line items (qty × unit price = line total). Subtotal = sum of all line totals. After-discount amount = Subtotal × (1 − discount%). Tax amount = After-discount × tax rate. Grand total = After-discount + Tax. Each line item is itemized separately so clients can see exactly what they are paying for.

Frequently Asked Questions
What should an invoice include?
A professional invoice should include: your business name and contact info, client's name and contact info, unique invoice number, invoice date and payment due date, itemized list of products/services with quantities and unit prices, subtotal, any applicable discounts, tax amount and rate, total due, payment terms (Net 30, due on receipt, etc.), and accepted payment methods. For tax compliance, include your business tax ID and the client's if required.
How do you calculate sales tax on an invoice?
Sales tax is calculated on the subtotal after discounts. Formula: Tax = (Subtotal - Discount) x Tax Rate. For example, on a $1,000 subtotal with 10% discount: discounted amount = $900, then at 8% tax: $900 x 0.08 = $72 tax, total = $972. Tax rates vary by state/locality (0-10%+ in the US). Some services may be tax-exempt. Always check your local tax regulations.
