How to Handle Electronic Sales Registration (EET) in Dynamics AX

The new EET law requires certain companies to implement electronic sales registration (Czech: elektronická evidence tržeb). This article is for those of you who are affected and who also use Dynamics AX (formerly Axapta).

At this point it looks like Microsoft won't be building an EET solution for its Dynamics AX ERP system. So it's up to every Dynamics AX (formerly Axapta) user to handle EET compliance on their own.

Although Electronic Sales Registration (EET) was approved by the Czech Chamber of Deputies some time ago, its technical specification was only published recently. Blue Dynamic has been following everything around EET closely, and we've prepared a ready-made EET solution for Microsoft Dynamics AX for you.

The Technical Solution in AX

The core technical component of EET is a central portal that, once you've registered and authenticated, issues a unique identifier for every business transaction. So the first step for every Dynamics AX operator is to ensure an online connection to this portal, which provides the so-called fiscal identification code.

The next step, which will also require customization in Dynamics AX, is ensuring that the fiscal identification code you receive appears on every document the law requires — above all, on the receipt. Of course, this isn't just about printing the code but also storing it in the database.

The complexity increases further with the need to handle situations where the operator's AX system can't connect online to obtain a fiscal code from the Financial Administration's portal. Even in this case, the tax document must still be assigned the appropriate ID, with everything reconciled with the EET portal once it's available again.

Our EET solution for Dynamics AX can be purchased as an add-on for Dynamics AX and Dynamics 365 in our store for Dynamics add-ons and applications — Addons.Blue.

A Quick Recap on EET

Before starting to register sales, every business subject to EET must apply for so-called authentication credentials. "This is the first and most important step toward registering sales electronically. It's important that businesses don't leave their applications until the last minute," emphasized Finance Minister Andrej Babiš.

Businesses have been able to apply for authentication credentials since 1 September 2016. "Businesses, or their authorized representatives, can apply either electronically via the Tax Portal, in which case the credentials are sent to their data box, or in person at any regional tax office, where they receive them on the spot in a sealed envelope," explained Deputy Finance Minister for Taxes and Customs Alena Schillerová.

Using the credentials they receive, the business then logs into the EET web application. Before they can begin registering sales, they need to enter details of every business premises through which they carry out the activities that generate the sales being registered. Once those details are entered, the business can obtain a digital certificate within the application.

Who does EET apply to? From 1 December 2016 it applies to the accommodation and hospitality sector; from 1 March 2017 the obligation extends to retail and wholesale companies.

"The certificate is how the Financial Administration identifies a business when it sends data messages. The number of certificates depends on the individual business's needs and is entirely up to them," added Alena Schillerová.

The certificate needs to be installed on the till/cash register device the business will use to register sales. Businesses will be able to test the functionality of a till with the certificate installed starting 1 November 2016.
