Checkout stops asking for a tax number you don't have

Buying from outside Türkiye no longer requires a Turkish tax number. The tax id is now asked for only where the law actually needs it — on a domestic sale — so an agency in Berlin or New York can complete a purchase with the details it genuinely has. The contact-name field is optional too; if you leave it blank we use the invoice name you already gave us.

Your invoice details are also remembered between purchases now. Fill them in once and the next checkout arrives prefilled, instead of ten blank fields every time. You can still change anything before you pay, and the invoice for each sale is always issued from the details recorded at the moment of that sale — editing your profile later never rewrites an invoice already sent.
