Frequently Asked Questions

How does the automatic tax calculation work?

Enter your tax rate as a percentage (e.g., 8.25% for sales tax or 20% for VAT). ZapInvoice multiplies each taxable line item by your rate and adds the tax amount to your invoice total automatically.

Can I use this for GST or VAT invoices?

Yes. ZapInvoice works with any percentage-based tax. Enter your GST rate (e.g., 5% in Canada or 10% in Australia), VAT rate (e.g., 20% in the UK), or any other tax rate. The label and rate are fully customizable.

Can I apply different tax rates to different line items?

Yes. You can set different tax rates for individual line items, or mark certain items as tax-exempt. This is useful when invoicing for a mix of taxable goods and non-taxable services.

Is the tax invoice format accepted by accountants?

ZapInvoice generates clean, professional invoices with a clear tax breakdown showing subtotal, tax amount, and total. This standard format is widely accepted for bookkeeping, tax filing, and expense reporting.
