Introduction

This article explains how to set up one-stop-shop (OSS) VAT in e-conomic so TRAEDE can correctly apply the VAT rates for all EU countries (except Denmark).
You will learn how to create VAT codes for each EU country and prepare e-conomic for correct VAT handling before synchronising with TRAEDE.

Create VAT codes in e-conomic

To configure OSS VAT correctly, you must create one VAT code per EU country, except Denmark.

You can access VAT code settings by navigating to:
Settings (gear icon) → VAT codes / VAT rates

Why create all VAT codes now?

Even if you do not currently sell to all EU countries, you should create all EU VAT codes in advance.
If a VAT code does not exist when TRAEDE tries to sync an order, the order will not synchronise into e-conomic. Creating them ahead of time prevents sync failures.

Example: Creating a VAT code for Sweden

Follow these steps to add a new VAT code:

1. Click New VAT code.

2. Under Account, choose the VAT account you want to use.

   • You may create one account per country or use a single shared “EU VAT” account—this is up to your reporting preference.

3. In Code, enter a short identifier combining the country code and VAT rate.

   • Example: SC25 for Sweden at 25%

4. In Name, enter a descriptive label such as Sweden 25%.

5. Set Rate to the correct VAT percentage (e.g., 25 for Sweden).

6. Under Type, select EU sales.

7. Click Save.

You will now see the newly created VAT code in your list.

Create VAT codes for all EU countries

Repeat the steps above for each EU country except Denmark.

Examples:

• DE19 – Germany, 19%

• ES21 – Spain, 21%

• NL21 – Netherlands, 21%

• SE25 – Sweden, 25%

Once all VAT codes are created, continue to the next article to learn how to configure OSS VAT within TRAEDE.
