What our customers say

We used to miss customer calls at peak hours. Now every call is logged, and a missed call gives us an instant call-back reminder.

Thu HangThu HangFurniture store manager

CRM is built into the call center, so sales no longer juggle two screens. Every customer conversation history sits in one place.

Minh TuanMinh TuanSales team lead

The AI-powered omnichannel call center runs very reliably. The technical support team is professional.

Anh ThanhAnh ThanhSales

Call reports are clear and transparent, and the figures always match, so billing and invoicing are easy.

Hong LinhHong LinhAccountant

Whether customers message us on Zalo or Facebook or simply call, everything lands on one screen. Our support team no longer splits up to watch each app.

Ngoc AnhNgoc AnhCustomer service, retail chain

The OMICall team really listens and keeps improving. On the road I just open the app to call, and customer details are saved right away.

We had no idea how many calls sales made or how good they were. Now one report shows each person performance.

Duc LongDuc LongChief Executive Officer

The app makes taking and placing calls easy when I do not have my laptop. The interface is clean and simple to use.

Even on business trips I can review and approve tickets easily, so customer care never stops.
