Tumi runs a thriving catering business in Sandton. Last Tuesday, she missed a R35,000 wedding order because she didn’t see the WhatsApp message until 6 hours later. The couple had already booked someone else.

“I was in the kitchen preparing for another event,” she told me, frustrated. “My phone was buzzing non-stop with messages—suppliers, random marketing spam, customers asking the same questions. By the time I saw the important message, it was too late.”
