When you're providing services to clients located in different countries, the complexity of tax regulations can be quite a challenge. Many times, these services may be exempt from certain taxes or subject to a 0% rate due to international agreements or specific tax laws. That's why we offer the option of the 0% tax type – to help you accurately reflect this on your invoices and in your financial records.

However, we understand that you may be curious about why you can't delete this 0% entry. The reason behind this decision is to ensure compliance with international tax regulations. Some countries may require specific documentation or evidence of the 0% tax rate for cross-border services. By retaining this option in your app, you're guaranteeing that you maintain a complete and accurate record of your transactions, which can be invaluable for tax reporting and audits. So, while deletion isn't an option, rest assured that it's here to streamline and ensure the compliance of your international business operations.
