Frequently asked questions
How do I remove VAT from an inclusive price?
Net = gross / (1 + rate). Tax = gross - net. That's the 'remove tax' mode.
What does 'exclusive' vs 'inclusive' mean?
Exclusive = tax added on top of a net price. Inclusive = the price already contains tax.
Which rate should I use?
Your local standard rate — commonly 5-25%. Set whatever applies to your context.
