Service Businesses in Any Country
zentroStack is built for service businesses worldwide. WhatsApp, Instagram and Messenger work in any country where those apps run, and the website call button works anywhere your website loads. Phone number options depend on your country, so contact zentroStack and we will check your local setup with you.
Many of the businesses we talk to work in more than one market, for example a cleaning company in the UK with customers who message on WhatsApp, or a clinic in the UAE that gets most of its new patient enquiries by phone and on Instagram. Tell us where your customers are and how they reach you, and we will suggest the simplest setup to start with.
