Keep personal chats personal.
A familiar place to talk to friends, family and people you know. It is not a replacement for a customer-service operation.
A clearer choice. A better fit.
WhatsApp vs Business App vs Business API.
Personal conversations. A small-business phone. A connected team. See what changes—and choose the setup that fits the way you work.

Start with the job, not the label
What does your next conversation need?
Each option has a purpose. The useful difference is how you organise the work around the message.
WhatsApp Business app
Run a business from the app.
Show your business details and products. Use app tools to organise chats and handle everyday customer questions.
WhatsApp Business API
Connect the conversation to the work.
Bring software, team ownership and configured customer journeys into the process through an appropriate platform.
The practical differences
Compare the tools. Understand the trade-offs.
API capabilities and the tools a provider includes are different things. SAYLS-specific entries below describe our published features; check the current plan for allowances.

Device allowances, paid app features and account eligibility can change. Meta’s current Business app guidance describes up to four linked devices, with additional access for eligible paid subscriptions. API team access is based on the software and plan you select; it is not a promise of unlimited users or messages.
When a chat becomes a team workflow
The API connects the channel.
SAYLS helps your team use it.

- Customer records beside useful conversation context.
