NullGlitch Tax Invoices turns Shopify orders and refunds into GST tax invoices and credit notes - adjustment notes in Australia - that match Shopify to the cent. Every figure comes straight from Shopify's own order and refund records; GST is never recalculated. If an order's tax doesn't add up, or carries another country's tax rate, we explain why in plain English and refuse to print rather than guess. Built for GST-registered Shopify stores in Australia and New Zealand.
