Marketplace in S2S and W2S with eBay Support (Temu Coming Soon)

Marketplace in S2S and W2S with eBay Support

We are releasing the eBay integration in the Marketplace module available in S2S and W2S programs. The integration allows you to connect multiple eBay accounts simultaneously and link them with your warehouse and sales management system.

What Do You Get?

  • 🧩
    Multi-account eBay – manage multiple accounts in one installation; separate settings, separate warehouses, single view.
  • 🔄
    Synchronization of key data: orders, stock levels, prices, and statuses – no manual transfers.
  • ⚙️
    Automation of typical marketplace tasks (e.g. stock/price updates based on rules).
  • 🧾
    Documents – eBay orders go into your ERP system, where you handle them using standard processes.

Supported ERP Systems

The integration works with popular systems:

Subiekt GT Subiekt NEXO Navireo WAPRO-MAG

Don't see your configuration? Let us know – we'll recommend the best option for your needs.

How to Get Started?

  1. Enable the Marketplace module in S2S or W2S.
  2. Add an eBay account (or multiple) and fill in the basic settings (warehouse, price list, sync rules).
  3. Connect with your ERP system (Subiekt GT / Subiekt NEXO / Navireo / WAPRO-MAG) and start synchronization.

Contact us – we'll help with configuration

What's Next?

Coming Soon We are working on the Temu integration in the Marketplace module. If you want to join the early access program – get in touch with us.

Have questions or want to migrate existing eBay listings? We'll help you choose the right configuration and sync rules for your sales model.

Improved Document Import Algorithm from Sellasist!


Improved Document Import Algorithm from Sellasist!

For W2S and S2S programs in the May version, we have introduced significant improvements to the algorithm for downloading invoices and receipts from Sellasist.

Since Sellasist does not provide API methods supporting fast import, we have implemented our own solutions in our programs that fully eliminate these limitations.

The result? Document downloading now works faster and more reliably.

We strongly recommend Sellasist users to update their programs to the latest version!

How the In Shop Tag Works


How Does the “In Shop” Tag Work?

The “in shop” tag indicates whether the program knows that a product is in the shop. If the tag is not checked, it means the program has no information about this product – it does not mean the product is not there.

What Happens When Sending a Product?

Fast method:

  • If the product is in the shop – the tag will be checked after refresh.
  • If it is not in the shop – an error message will appear in S2S → Subiekt → Errors, and the product will not be added.

Exact method:

  • If the product exists – it will be overwritten with data from Subiekt.
  • If it does not exist – it will be added as new with full data.
Warning: overwriting may cause loss of description, photos, change of manufacturer, category, or name!

Incremental method:

Works automatically based on the tag:

  • Tag checked → fast method
  • Tag not checked → exact method

Why Start with the Fast Method?

Sending products first with the fast method allows you to check which ones are already in the shop. This way:

  • You won't overwrite data unnecessarily,
  • You'll save server resources,
  • You'll preserve photos, descriptions, and other data in the shop.

Additional Program Options

  • Adding only new products
  • Syncing Subiekt data based on the shop – works as a backup
  • Updating only selected fields – e.g. name, description, photos, EAN
Recommendation: always back up your database before updating!

Error 400 on Shoper Platform


We would like to inform you that some shops based on the Shoper platform may currently experience connection issues with our programs: s2s, w2s, A2C. This situation is not caused by our application and results from factors on the Shoper platform side.

If you have encountered connection errors (e.g. error code 400), we suggest a temporary workaround by entering the technical shop address instead of the main address during license activation. The technical address is a special, internal shop address assigned to every Shoper account.

Thank you for your understanding – the Shoper technical team is working on resolving the issue.
