Multichannel commerce brings both opportunities and challenges: As a retailer in eCommerce, you are faced with the task of maintaining your brand presence across different sales channels, while at the same time having to master the complexity of inventory management, pricing and logistics. In this article, we take a look at the importance of data quality in multichannel retail and show you how you can successfully master these challenges with JTL and countX.
Your strategy for more growth
With solutions such as JTL-eazyAuction, it is very easy to manage sales via different marketplaces at the same time. Thanks to the seamless integration with your ERP, all transactions on Amazon, eBay and other marketplaces can be managed centrally and efficiently. Regardless of your marketplace interface, there are various aspects to consider in order to set up your multichannel retail business for the long term. We have compiled the most important ones for you:
Data quality as the key to success in multichannel retail
In multichannel retail, it is becoming increasingly important to maintain an overview of all relevant data as the number of data sources increases. For example, every Amazon seller knows the problems of order creation or activation of the VAT Calculation Service (VCS). This is where we at countX come in: As experts in simplifying and optimizing tax processes in eCommerce, we place particular emphasis on data quality and consistency.

In the countX customer portal, so-called “Health and Plausibility Checks” are carried out, which check your receipt data for VAT correctness independently of the marketplace. This means that the document must match the transaction. The devil is in the detail here, especially with thousands of monthly transactions and different data sources. Any errors found are displayed directly and can be downloaded as an Excel list. After the correction, you simply upload the file again so that your advance VAT return is created on the basis of valid data.
After checking your invoices, you will find the entire outgoing invoice book – and therefore your collected multichannel sales – in your customer portal. You can query these for your desired period, which allows you to read out the total turnover from all marketplaces within a specific period. It is also possible to filter for transactions that are relevant for the OSS process. You can make this processed data available to your tax advisor. With countX, your data is accurate and reliable – even in a complex multichannel environment.

Influence on the OSS procedure in international trade
As soon as you internationalize your multichannel trade and carry out transactions within the EU, the processing of the OSS procedure is also affected by data quality. Regardless of the down payment of transactions and marketplaces, it is important to ensure that every single invoice is issued correctly. This is the basis on which the OSS procedure is calculated and your VAT is paid.

It gets tricky if there is not just one central warehouse within a national border, as this increases the number of cross-border transactions. If, for example, you use Amazon’s PAN-EU program or an additional fulfilment provider abroad, then some special features must be taken into account in the OSS process.
