How we build AI follow-up via WhatsApp for SMB clients.

No chatbot with "how can I help you?". An AI that summarises leads, pings you, and confirms with the client within 30 seconds.

Every SMB owner knows it: a good lead comes in exactly when you are in a meeting. By the time you call back, the client is already with someone else.

The solution does not have to be a chatbot (which mostly just annoys). We build something simpler and more effective.

How it works in practice

  1. Someone fills in a short intake on your site. 3 fields max.
  2. Right after, WhatsApp opens with a prefilled message: "Hi! I just filled in the form on your site. Can we talk about [X]?"
  3. In the background: AI reads the intake, makes a compact summary, and puts it in your CRM.
  4. You get a short notification ("New lead: aircon Moraira. Marleen, likely high intent"), not a 4-page document.
  5. The lead gets an automatic WhatsApp within 30 seconds: "Thanks Marleen! We will get back to you today at the latest."

Why AI and not just an auto-reply?

Auto-replies are generic and irritating. AI can:

  • Personalise: mentions the name, restates the question, makes clear someone is reading along
  • Qualify: recognises from the intake whether someone likely has high or low intent
  • Summarise: so you do not have to read through a long story to get the core
  • Route: pings colleague X if it is about service X, colleague Y if it is about service Y

What we do NOT do

We do not build chatbots that "have conversations" with the client. People see through them and get frustrated.

Other things we do not do:

  • No bots that pretend to be human
  • No 24/7 "answer everything" AI that promises things that are wrong
  • No automations that take over your client contact — only support it

The tools

We usually work with:

  • WhatsApp Business API: for reliable, verified messages
  • Make or n8n: for the workflow logic
  • OpenAI / Anthropic: for the AI summary (via API, not the ChatGPT UI)
  • Your CRM: Pipedrive, HubSpot, or custom

Under the hood no black box. Everything is explainable and portable to another party if you ever want that.

What does it cost?

Setup varies. Roughly:

  • Basic WhatsApp flow + AI summary: 1 week of work
  • Extended routing + CRM integration: 2–3 weeks
  • Recurring cost: ~€30–80 per month for tools + WhatsApp API traffic

Usually you earn that back within 2–3 months on one extra job won.

A short warning

AI follow-up only makes sense if the process behind it holds up. If you then do not call back for 2 days, the 30-second confirmation is worthless — you just shift the disappointment 30 seconds.

Fix the process first, automate after. Never the other way round.
