Invoicing tips
For B2C invoices, you typically include tax in the displayed price. Use "Add tax" mode.
For B2B invoices in EU, VAT may be reverse-charged (recipient handles it). Check your accountant's setup.
For multi-region commerce, save the correct rate for each jurisdiction in your invoicing system, not memory.
