Which one is quicker?
Phone for short questions, the form for anything with scope to it. When you fill in the form, a paragraph on what you want to do is enough — we pin down the rest on the call.
Phone and WhatsApp are the same number. There's no switchboard; when you call, you reach the person doing the work.

What to mention in the form
If you write these five things, we can talk about a price range on the first call. If you don't, that's fine too — we'll ask the same questions on the phone.
- Your business and sector: who you sell to
- Whether you already have a site, and its address
- What you want from the site: presence, collecting enquiries, selling, managing dealers
- Roughly what budget you have in mind; this is what sets the scope
- Any target date (a trade fair, the start of a season, a launch)
Personal details you send through the form are processed only to assess your request. The specifics are on our Privacy Policy and KVKK notice pages (KVKK is Turkey's data protection law).
