Form fields for the e-invoice
TAXES Fields for Gravity Forms
Calculating net, tax and gross correctly, even when one form contains different tax rates: TAXES Fields for Gravity Forms takes care of it. The plugin brings pricing fields with VAT into your forms, and the visitor sees the amounts while still choosing. On saving, your server calculates everything again, so the entry holds only amounts that the server itself has determined.
The principle: each pricing field carries a tax code that sets the tax rate and the tax category. From this, the form calculates the net amount, the tax per tax code and the gross amount. Gravity Forms is a form plugin for WordPress.
