Timologia for WooCommerce PRO adds Greek invoicing fields to WooCommerce checkout and administration. Customers requesting an invoice can provide a VAT number, tax office, and profession with their order.

Checkout invoice fields

When a customer requests an invoice, the VAT, tax office, and profession fields can be required. You can change the invoice dropdown wording from Yes and No to labels such as Invoice and Receipt. The company field can be moved alongside the invoice fields; when moved, it becomes required. Required fields can also be marked with the required CSS class.

EU VIES and AADE VAT tools

EU VIES validation checks a customer's VAT number. When validation is enabled, a failed check stops the order and notifies the customer. A successful VIES response is recorded in the administrator's order screen. You can disable VAT validation if that workflow does not fit your store.

AADE provides a separate VAT workflow. Customer VAT details can be validated against the AADE tool, with fields filled in automatically. A backend option can also retrieve VAT details from AADE and make a customer account.

Customer profiles and orders

Invoice fields appear in the backend user profile and admin order details, where administrators can review or edit them. For phone orders, an administrator can pull saved details from the customer profile and adjust them as needed. Invoice fields can also be included in emails sent to clients.

Features listed as coming soon

PDF invoice creation with custom numbering, PDF receipt creation with custom numbering, and POL39 are listed as Coming Soon. They should be treated as planned capabilities, not available functions.

Setup and compatibility

Install and activate the add-on on a WordPress site with WooCommerce, then configure the invoice fields, company field placement, dropdown wording, and VAT validation for your store. The listed requirements are WordPress 3.5.1 or newer, Apache 2.1 or newer, and PHP 5.4 or newer. The extension listing says it has not been tested with the latest three major WordPress releases and may have compatibility issues with newer versions.
