Let me guess. Your customer details live in three places right now — a notebook, a phone gallery full of screenshots, and one very messy Excel sheet that only you understand. If that made you smile (or wince), you are not alone. Almost every small business starts this way. It works fine when you have ten customers. But at fifty? You start forgetting follow-ups. Leads go cold. A client calls and you quietly scroll through old WhatsApp chats while saying "yes sir, one second."
