What is an Invoice Generator?
An invoice generator turns a list of products or services into a priced bill. You enter each line as a description, a quantity, and a unit price; the tool multiplies and sums them, applies any discount, and adds tax to arrive at the amount due. It's the everyday math behind freelancer and small-business billing.
Use it to draft an invoice, double-check a supplier's totals, or test how a discount or tax rate changes the bottom line. The figures are general informational estimates, not professional tax, accounting, or financial advice — consult a CPA for the correct tax treatment.
❓ Frequently Asked Questions
How are the invoice totals calculated?
Each line is quantity multiplied by unit price; those line amounts add up to the subtotal. A percentage discount is taken off the subtotal first, then the tax rate is applied to the discounted amount — so tax is charged on what the customer actually pays, not the pre-discount figure. The total is the discounted subtotal plus tax.
Should tax be applied before or after a discount?
This tool applies the discount first and then taxes the reduced amount, which is the common convention for trade and promotional discounts. Rules vary by jurisdiction and discount type, so confirm the correct treatment for your sales tax or VAT before issuing the invoice.
Is this a legally compliant invoice?
It computes the math, but a compliant invoice also needs items like your business details, an invoice number, dates, and the customer's information. The figures here are general informational estimates, not professional tax, accounting, or financial advice — consult a CPA for tax treatment and invoicing requirements.
