i build AI tools that sit on top of CRMs for small businesses: salons, restaurants, clinics, agencies. in the last 5 months we connected 250 clients in 22 countries without spending a cent on ads, so i've seen a lot of whatsapp + CRM setups. no product here, just stuff i wish someone told our clients earlier.
1. whatsapp app ≠ whatsapp API. most small teams run on the business app on one phone. a CRM can't really work with that. you need the official API connection, otherwise "integration" just means copying chats by hand.
2. track the lead source from day one. meta ad, tiktok, referral, walk in. sounds boring, but after a month it tells you where your money actually works. most teams we talk to have no idea.
3. speed beats features. people message 3 businesses at once and go with whoever answers first. the best CRM in the world doesn't help if the lead sits unread until the morning.
4. don't build automations before you know your stages. teams buy a CRM, spend weeks on chatbots, then realize their pipeline is different from what they thought. map your stages on paper first.
5. a small team doesn't need an enterprise CRM. pick something cheap with a solid whatsapp API connection and grow from there.
curious what others here run for whatsapp heavy businesses. what's actually worked for you?
