A WhatsApp number for the business, not the owner's

A WhatsApp number for the business, not the owner's

In many small businesses, customers message a single number: the owner's. At first, it is convenient. Then the business grows, and that number becomes a trap.

Three problems with the owner's number

  • When the owner is asleep, travelling or in a meeting, nobody answers. The customer waits, then messages a competitor.
  • Personal and business life get mixed up. Family messages get lost among orders, and orders get lost among family messages.
  • When an employee uses their own number for customers, one day they leave with it. The contacts, the order history and the customer relationship go with them.

The strategy: a number that belongs to the business

  1. Get a SIM card dedicated to the business. This number is only for customers. It stays with the business, whoever answers.
  2. Install WhatsApp Business, WhatsApp's free app for businesses, with that number.
  3. Fill in the business profile: company name, description, address, opening hours. Add your catalogue of products or services.
  4. Connect the team's devices. In WhatsApp Business: Settings › Linked devices › Link a device, then scan the QR code from WhatsApp Web on the office computer, or from another phone. Several people can then answer customers on the same number.
  5. Turn on two-step verification on this number, so nobody can steal it.

What it changes

  • The whole team answers, even when the owner is away.
  • The history stays: if an employee leaves, just log out their device. Customers and conversations stay with the business.
  • Your personal number becomes personal again.

Going further

In short

A SIM for the business, WhatsApp Business, and the whole team connected. The number belongs to the business: customers stay.
