The free WhatsApp Business App is designed for small businesses to manage a low volume of chats from a single device. The WhatsApp Business Platform (API) is built for medium to large enterprises that require scalability, automation, and integration. The API allows you to connect WhatsApp to your existing systems (like a CRM), handle high volumes of messages, use chatbots, and enable multiple agents to support customers from a unified dashboard. NexusFlow is a platform built on top of this powerful API.
While Meta's Cloud API provides the core messaging function, it is a raw developer tool that requires significant in-house resources to build, manage, and maintain. NexusFlow provides a critical layer on top of Meta's infrastructure, offering a complete enterprise-grade solution out-of-the-box. This includes a 99.99% uptime SLA, 24/7 expert support, a user-friendly dashboard for non-technical teams, advanced analytics, and pre-built integrations. With NexusFlow, you accelerate your time-to-market and ensure your mission-critical communications are always online without the engineering overhead.
Our pricing is completely transparent and designed for partnership. The total cost has two components: Meta's conversation-based fees and NexusFlow's platform fee. Meta charges a small fee for each 24-hour conversation, which varies by country and whether the conversation was initiated by you or the customer. We pass these costs on directly with no markup. Our platform fee is a tiered subscription that covers all our value-added services: the 99.99% uptime SLA, dedicated support, the management dashboard, analytics, and our managed infrastructure. This fee decreases per-message as your volume grows.
The process is straightforward and we guide you every step of the way. First, your business must have a verified Meta Business Manager account. Our onboarding team will then help you create a WhatsApp Business Account (WABA) and connect your phone number. We handle the technical setup and submit your account for approval, ensuring everything meets Meta's policies. Most businesses are approved and ready to start messaging within a few days.
Yes, in most cases you can use an existing phone number, including landlines and toll-free numbers, as long as it is not currently active on another WhatsApp account (either the personal app or the Business App). The number must be able to receive an SMS or voice call during the one-time verification process to confirm your ownership.
