Hi Product Hunt community,

I built WhatsFlow CRM & Seller Vault because thousands of e-commerce stores, bespoke boutiques, and direct-to-consumer brands close 80% of their daily sales directly inside WhatsApp Web, yet they still rely on messy spreadsheets or Notepad to track orders, deposits, and customer follow-ups.

Most existing WhatsApp tools either require expensive per-message API fees, force you out of the standard WhatsApp Web interface, or route sensitive customer conversations through third-party cloud servers.

WhatsFlow CRM solves this by adding a fast, privacy-first CRM sidebar directly inside WhatsApp Web:

1. Visual Sales Pipeline: Tag any active chat as New Inquiry, Pending Deposit, Ready for Dispatch, or Completed, and filter your chat list by stage in one click.

2. Instant Order Receipt & COD Balance Calculator: Enter item prices, advance payments, and shipping fees to calculate the exact Cash-on-Delivery (COD) balance and insert a formatted order summary directly into the chat box.

3. Custom Quick-Reply Vault: Save and trigger bank details, sizing guides, and shipping policies in one click without retyping.

4. 100% Client-Side Privacy: Zero chat logs, phone numbers, or customer records ever leave your browser. Everything is stored locally on your machine and exports cleanly to CSV.

You can install it directly from the official Chrome Web Store and test every feature with a 7-day free trial:

- Official Chrome Web Store: https://chromewebstore.google.com/detail/whatsflow-crm-seller-vaul/dkhhcnchpoopgkdphmjiljfldinpmibk

- Interactive Demo & Overview: https://laxsaj.store/extension

Pricing after the 7-day free trial is simple: $19/month (Starter), $39/month (Pro), or a $99 One-Time Lifetime License for early adopters.

I would love to hear your feedback: What is the biggest bottleneck you face when managing customer inquiries or closing sales on WhatsApp Web, and what feature would you like to see in v1.1?
