How it works

The subtotal is quantity times unit price; the discount comes off first, shipping is added, and tax is charged on the discounted goods plus shipping, which is how most tax authorities expect it.

Frequently asked questions

Is tax charged on shipping?

In most VAT and sales-tax regimes yes, so the tool taxes goods plus shipping. Set shipping to zero if yours is exempt.

Can I use it for quotes?

Yes — the arithmetic is identical for quotes, estimates and proformas.
