Tools for WhatsApp Business

Everything you need to plan, launch, and optimize your WhatsApp API strategy.

WhatsApp API Cost Calculator

Estimate Meta INR messaging charges effective 1 October 2026, with recipient-market rates, marginal tiers, Service allowance and eligible free-entry exclusions.

Lead Qualification ROI Calculator

Compare user-entered costs and qualification rates in one currency. Zero qualification means zero leads; ratios with zero denominators are unavailable. Results are scenarios, not prices or promised savings.

WhatsApp Link Generator

Create wa.me links using an international number and an optional encoded message. Edits clear old links. This does not verify WhatsApp availability or send a message.

QR Code Generator

Generate local PNG QR codes for text, HTTP(S) URLs, WhatsApp, email, phone and Wi-Fi. Required fields, colors and image size are validated; edits clear the old preview. Test your PNG with the intended scanner.
