I need our existing website to offer a friction-free way for visitors to reach us on WhatsApp. The result should feel native: one click on any page opens a branded chat window that works smoothly on both desktop and mobile, routes messages straight to our WhatsApp Business number, and lets my team reply from the official app or a web dashboard. Key points you should cover in your proposal • Which tool or approach you plan to use (e.g., official WhatsApp Business API, Twilio, Chat-API, simple widget from Meta’s documentation, etc.) and why it fits a lean budget under fifty dollars. • How you will embed the chat widget or button so it loads quickly without affecting Core Web Vitals. • Any added value you can provide—like basic auto-replies during off-hours, file-sharing capability, or a lightweight ticket handoff—so long as it stays cost-effective. • Implementation steps, estimated time to complete, and any access or assets you’ll need from my side. Acceptance criteria 1. A working WhatsApp entry point that displays on every page (or specific pages we decide). 2. Messages initiated from the site appear instantly in our WhatsApp Business inbox. 3. Styling matches our brand’s colors and fonts. 4. No login required for visitors; they should start a chat in a single tap. 5. Code is clean, documented, and delivered so my developer can maintain it. If you’ve done similar low-cost integrations before, a quick example or link will help me choose faster.
