Belgrade waterfront — Viber business messaging in Serbia

Why should Serbian businesses invest in Viber bots?

Because Viber is the default consumer messenger in Serbia (often cited ~90% penetration and #1 rankings). Commercial bots plus partner Business Messages cover support, orders, and opted-in promos. WhatsApp remains useful for tourists and multi-country Balkan/EU expansion — run it on Ominiflow where Meta is stronger.

In Serbia, Viber is not “another app” — it is how friends, families, and customers already talk. Messenger rankings and CPaaS country guides regularly place Serbia in Viber’s #1 tier with penetration near 90%. Business messaging has to meet that habit with official bots, not grey-market scrapers.
