Why

At 50–200 inquiries a month split B2C and B2B, with three people sharing WhatsApp and phones, the loss isn't from missing analytics — it's from no shared view of who said what to whom. B2B leads (architects, contractors, bulk orders) need a different follow-up rhythm than walk-in B2C, and right now you have neither pipeline. You're also running paid Facebook and Google ads, which means every lead has a real ad cost behind it; ghosting one is throwing money away twice.

What you actually need

1. [Zoho Bigin, free for 1 user / ₹400 per user per month Express plan in India] — two pipelines (B2C walk-in, B2B project), native WhatsApp Business and email integration so every lead lands as a record. India-priced, mobile app for the shop floor.
2. [AiSensy, ~₹1,500/month Basic + Meta per-message fees] — a shared WhatsApp Business API inbox so all three of you reply from one number with templates for catalog/quote follow-ups. Note: from January 1, 2026, WhatsApp bills per template message delivered, not per conversation, and for Indian recipients each utility template costs ₹0.145 per message delivered (marketing ~₹1.09) — check current pricing before launch.
3. The 10-minute end-of-day habit — one person reviews every Bigin record touched today, marks next action + date. No tool replaces this.

Do this today

Open bigin.com, start the free plan, create two pipelines: "B2C Walk-in / Ad" (stages: New → Visited → Quoted → Won/Lost) and "B2B Project" (New → Site Visit → Quoted → PO → Won/Lost). Connect your Gmail and your WhatsApp Business number under Settings → Channels. Enter the last 20 inquiries from your phone right now. Done in 30 minutes.

What to ignore

HubSpot Sales Hub and Salesforce are wrong here — G2 reviewers cite Bigin delivering pipeline, contact tracking, email and workflow automation at a fraction of HubSpot or Salesforce's cost, with one user noting a month of HubSpot equals a year of Bigin. Skip Zoho One bundles too; you don't need Desk, Books, Campaigns, Projects yet. Skip any "AI sales agent" add-on — your problem is data entry discipline, not AI.

What doing nothing costs you

You're paying Facebook and Google for every click; leads that sit unanswered past 24 hours on WhatsApp are paid traffic you bought and then threw away. With three people, one quoted ₹50,000 order forgotten per month is more than a year of Bigin and AiSensy combined.

Where this leaves you

You'll get: one place every B2C and B2B lead lives, a shared WhatsApp number with templated catalog/quote replies, and a daily 10-minute habit that catches slippage before it becomes lost revenue. The contrarian bit: stop measuring "CRM features" and start measuring whether your team can answer "what's the status of that architect from last Tuesday?" in five seconds.

When to revisit this

When you cross ~300 leads/month, or hire a 4th person dedicated to sales — then look at Bigin Premier or Freshsales, not before.
