Do you sell your goods via Amazon? Then the stable version of JTL-Wawi 1.10 has a welcome innovation in store for you: a completely revised handling of the Amazon VAT Calculation Service(VCS). This makes the processing of tax data and invoices simpler, more transparent and more stable. You can invest the time saved directly in trading via our four new marketplace connections. But that’s not all: 80 percent of our development effort has gone into stabilization this time to optimize the performance and reliability of JTL-Wawi. In this article, we will show you the advantages of the new version, especially for your multichannel commerce.
Amazon VCS rethought - What's changing for you
If you sell via Amazon, you are probably already familiar with the VAT Calculation Service – VCS for short. Amazon takes care of the VAT calculation for you. Depending on the variant, Amazon also creates the invoices (VCS) or only provides the tax data (VCS Lite). If you don’t use an Amazon service at all, you can still upload your own invoices – this is done via the so-called IDU option (Invoice Data Upload).
With JTL-Wawi 1.10, we have completely revised the processing of this VCS data. The new system now automatically recognizes whether it is VCS, VCS Lite or IDU data. So you no longer have to worry about what should be processed – JTL-Wawi does it for you.
Processing has also become significantly more error-tolerant:
Particularly practical: VCS-Lite data can now be requested retrospectively for up to 30 days. This is helpful if booking data is missing or has been subsequently updated. The data can be provided in several reconciliations, as Amazon delivers the data with a time delay.
A lot has also changed in the JTL-Wawi interface:
These changes will make the interaction between Amazon, VCS and JTL-Wawi much easier – and save you valuable time in your day-to-day business.
