Multiple bank account numbers can be entered in the account issuer's details, and the default format of the account – whether electronic or paper-based – can also be set.

This version includes a new validation of the referenced invoice number, and the unit price can be specified with four decimal places.

The new version follows the current legal regulation of CDV control numbers and allows the selection of “domestic VAT taxable person” type customers in the case of an EUE VAT rate (a non-reverse charge transaction carried out in another Member State).

In this update, we have clarified the calculations and validations related to invoicing, improved the management of discounts, and refined the management of templates and tax bases.

In this update, we have modified the process of recording Hungarian tax numbers upon invoice issuance and customer management, and we also made the exchange rate handling more accurate.

- We made the operation related to the connection between “Hungarian tax number” and “Group member tax number” more user-friendly. In certain cases, we introduced a new way of error management and messages that facilitate navigation for users. - In order to enhance user experience, we performed further bug fixes in the application.

- In the 'Customers' tab, it is now also possible to record the tax number of the group member, so that the invoices issued to the registered partners can also contain information on the VAT group members. - Minor bug fixes and performance optimisations.

Changes that help ensure the safe use of the application, but do not affect functionality. Minor bug fixes and performance optimizations.

Previously, the system only managed the group tax number for the seller data. This is now possible by extending the functionality to customer data. The application has been supplemented by the introduction of predecessor-successor functions: • if the logged-in user has predecessors, a new option is available on the interface to view the invoices of the predecessor, • in cases of succession, the successor can issue an invalidating (and modifying) invoice by referring to the invoice of the predecessor.

The "settle the invoice" function of the application has been enhanced. The new labelling system: - Unsettled - Settled - Partly settled The status of the invoice settlement is displayed on the invoice list page and on the details page. A new operation „Payments” is available for the invoice issued. On the Payments screen, the payments for the invoice are displayed. The previous "settle the invoice" operation is also retained.

Development Recording the data erasure code required for the permanent deletion of the data stored on the durable data storage device on the invoice and establishing the related data provision. Correction of error Full visibility of the "Date selector" function under the "First registration" date field when modifying a KBAÚK VAT-rated product.
