Same product, same basket, different expectations. Payment method, the returns process and how price is displayed drive conversion in Germany, and all three leave marks in the store software.
Paying on invoice and by direct debit are established habits in Germany; a store accepting only cards narrows itself from the start. It is an integration task, but the consequences reach into accounting: with payment on invoice the moment of order and the moment of collection separate, and the system has to track them independently.
The right to return is a strong consumer expectation and in practice the most-touched flow in a store. If how the label is produced, how stock is restored, when the refund is issued and how that reaches accounting are not designed up front, every return is processed by hand. The legal framing belongs to partner law firms; we build the flow.
What has to appear alongside the price is detailed in Germany, and it comes from product data rather than design. If unit price, delivery information and tax display are not in the product record, no theme can fix it. That is why looking at the product data model before starting on store design comes out cheaper.
Usually yes. The common platforms either have the payment and display capabilities Germany needs or they can be added. Replacing only comes up if the product data model cannot carry the required fields at all, which is rare and worth measuring before assuming.
In category and product copy, translation usually stays visible and does not help in search either; German buyers look for the product using different words. The best result in practice is writing the copy for the best-selling group in German and progressing from there.
