How to turn WhatsApp and Viber messages into real CRM leads

The Bulgarian context

Bulgaria is one of the few European markets where Viber remains dominant. For restaurants in Sofia and across the country, Viber is often the primary communication channel — more so than WhatsApp, which is more common with international guests and younger demographics.

The challenge is that Viber and WhatsApp conversations are happening in separate apps, with different contacts, and almost no integration with any kind of business system. Every conversation disappears into a phone's message history and is never seen again.

What is a CRM and why does a restaurant need one

A CRM — customer relationship management system — is simply a database that tracks who your guests are and what their history with you looks like. For a restaurant, a useful CRM entry might look like this:

Мария Петрова — first contact via Viber, 14 March. Asked about birthday dinner options. Booked table for 8, Saturday 19 April. Preferred channel: Viber. Last visit: 19 April. Notes: celebrating birthday, requested no-nut dessert option.

With this information, you can do things that most Bulgarian restaurants simply don't do: send her a personalised message 11 months later asking if she'd like to book for her next birthday. Offer her a special if she brings a group again. Remember her dietary preferences.

This is what large hotel chains do with their loyalty programs. There's no reason a neighbourhood restaurant in Sofia can't do the same thing — especially now that the tools exist to automate it.

The problem with manual CRM

Every restaurant owner we've spoken to understands the value of knowing their guests. The problem is time. After a busy Saturday service, nobody is sitting down to enter Viber conversations into a spreadsheet. It simply doesn't happen.

The only way a CRM works for a restaurant is if it fills itself automatically from the communication channels that guests actually use.

How automated CRM works in practice

When a guest sends a WhatsApp message to your restaurant number, the system captures: their phone number, the time and date, the content of the message, and the channel they used. It creates a guest record automatically.

When that same person messages again three months later, the system recognises them. It knows their history. The response can be personalised: "Здравейте Мария, добре дошли отново!"

Over time, you build a picture of your guest base: who your regulars are, when they typically visit, what they usually ask about, which channel they prefer. This data is genuinely valuable for marketing decisions — not just a nice-to-have.

The practical setup

For WhatsApp, you need a WhatsApp Business account connected to your restaurant's phone number. Messages come in, get handled automatically, and are saved to your guest database.

For Viber, you need a Viber Business account — the approval process typically takes 2-3 days. Once approved, the same flow applies.

Both channels can be managed from a single dashboard, so you're not jumping between apps to see what's happening.

What you should track for every guest

At minimum: name or identifier, preferred contact channel, first contact date, last contact date, number of visits or bookings, and any specific notes (allergies, preferences, special occasions). This takes seconds to capture automatically and provides years of value.

The long-term payoff

Restaurants that know their guests outperform those that don't on every metric that matters: repeat visit rate, average spend per visit, word-of-mouth referrals, and resistance to competition. A guest who feels recognised and remembered is dramatically more loyal than one who feels anonymous.

Building that guest intelligence starts with the first WhatsApp or Viber message. If you're not capturing it, you're leaving a permanent asset on the table every single day.
