Should I charge tax on my services?

It depends on your location and the type of service. Most physical goods are taxable. Services vary by state/country. Consult a local tax professional for definitive guidance.

Is tax applied before or after the discount?

In this calculator, tax is applied after the discount — which is the standard practice and most favorable for the client.

What is the difference between sales tax and VAT?

Sales tax is charged once at the point of sale (common in the US, 0-10.25% depending on state/locality). VAT (Value Added Tax) is collected at every stage of production and distribution (common in the EU and most countries, typically 10-25%). Both add to your invoice total, but the collection mechanism differs.
