Getting Ready for IOSS

In order to set our system so it is ready for IOSS, the following settings should be set as required. If you require more information about each of these settings please contact the training team here,


Read the IOSS information for KCC user here, EU Vat Import One Stop Shop (IOSS) to ensure you meet the criteria for IOSS.
Please Note: After setting the below options as required you MUST contact as we also need to make a minor update to your system. This will require all users to log off for a few moments.

System Values

Your system must be configured to use IOSS System Values - it is disabled by default.
  1. Go to [System Setup | System Values].
  2. Click Edit.
  3. Set Europe Opt-In IOSS Scheme setting as required.
    1. Enabled - This will enable the IOSS functionality within the system
    2. Disabled - IOSS functionality will remain off.

System Data

Within System Data there are a number of options that may need configuring. Each location of the settings is covered below.

Tax Rates

You are now able to specify a default tax rate. When this is set you will no longer need to specify the VAT rates for each stock item. Set a default rate and the system will use this if no specific rate has been applied to the item.
  1. Go to [System Setup | System Data | Tax Rates].
  2. Click Edit.
  3. Enable the default checkbox for the tax rate you wish the system to use as the default
  4. Click Save Screen.

Brand IOSS Numbers

Each of your brands may have its own IOSS number and this can be recorded in KCC. This will be used by the system for any sale under the relevant brand.
IOSS numbers recorded against a brand will take priority over the IOSS number specified in System Values.
  1. Go to [System Setup | System Data | Branding].
  2. Click Edit.
  3. Enter the IOSS number for each of your brands as required.
  4. Click Save Screen.


Each of your channels may each have an IOSS number recorded against it for sales imported from that channel.
An IOSS number recorded against a channel will take priority over Branding and System Values IOSS numbers.
  1. Go to [Channels] and double click the channel to be set for IOSS.
  2. Click Edit.
  3. Set the External Marketplace toggle as required.
    1. If your marketplace such as Amazon and eBay is collecting tax on European sales orders, this should be enabled.
  4. In the Import Options box enter the IOSS number to be used for sales from this channel - your marketplace should provide this information.
  5. Click Save Channel.

Sales Orders

The IOSS number being used for a sales orders is visible from within the sales order in the Additional tab.


When viewing the Tax Register you can now see the tax Country for the order as well as the IOSS number used for the sale. A future update will allow the IOSS number to be filtered so that tax returns per IOSS number are possible.

A New system Nominal has been introduced called “External Sales Tax”. Orders which have come from a channel with the External Marketplace setting enabled will have the VAT on sales orders posted to this nominal. The Tax on these orders will not be included on your Tax Return, it will only post the NET sales figure.
