# What is WhatsApp Business? Complete Guide for Companies

WhatsApp Business is the version of WhatsApp built specifically for companies to communicate with customers professionally, organized and — when volume grows — automatically via API. Over **200 million businesses** worldwide use WhatsApp Business as their official customer service, sales and marketing channel.

## What WhatsApp Business is in one sentence

It's the **business version** of WhatsApp: same familiar app, but with company profile, catalog, auto-replies and — for those needing scale — an **official API** that connects WhatsApp to your internal systems.

## What WhatsApp Business is for

Companies use WhatsApp Business for:

- **Customer support** — answer questions, resolve issues
- **Transactional notifications** — order confirmations, delivery status, reminders
- **Identity verification (OTP)** — security codes for login
- **Sales and catalog** — show products, close orders via chat
- **Direct marketing** — promotions, launches (always with opt-in)
- **Post-sales** — satisfaction surveys, warranty

## The two versions of WhatsApp Business

There are two ways to use WhatsApp Business. Pick wrong and you waste time or money.

### 1. WhatsApp Business app (free)

- Free download on Play Store / App Store
- Runs on **one phone**
- Good for up to **~50 conversations/day**
- Has business profile, catalog, labels, quick replies
- Doesn't integrate with CRM or systems

**Who uses it**: brick-and-mortar shops, freelancers, solopreneurs.

### 2. WhatsApp Business API

- Access through official providers (BSPs) like [Zavu](https://www.zavu.dev/en/whatsapp-business-api)
- No practical message limit
- **Multiple agents** on the same number
- Integrates with CRM, e-commerce, custom apps
- Allows **AI agents** answering automatically
- Charges per conversation ($0.005–$0.025 in US)

**Who uses it**: e-commerce, fintech, SaaS, high-volume businesses.

## How much WhatsApp Business costs

**Free app**: $0.

**Official API**: pay per initiated 24h conversation. Meta categories for 2026 (US):

| Category | When | US Price |
|---|---|---|
| Utility | Transactional notifications | ~$0.015 |
| Authentication | OTPs, verification codes | ~$0.005 |
| Marketing | Promotions, launches | ~$0.025 |
| Service | When customer initiates | $0.00 |

Providers like Zavu charge only Meta's cost, no markup. You [see full pricing](/en/pricing) before starting.

## How to get started with WhatsApp Business

### For micro-businesses (app)

1. Download **WhatsApp Business** from Play Store or App Store
2. Register your business phone number
3. Configure profile: name, category, address, hours, website
4. Add greeting and away messages
5. Create your catalog with products and prices

### For volume businesses (API)

1. Create free account at [zavu.dev](https://www.zavu.dev/en)
2. Connect your **Meta Business** account (no documents, 5 min)
3. Verify the number you'll use (must be **outside** the app)
4. Create and submit your **templates** for Meta approval (24-48h)
5. Send your first message in 5 lines of code

## Important limitations

- **24-hour window**: you can only send free-form messages within 24h of the customer replying. Outside that, you need **approved template**.
- **Marketing content in Utility templates** isn't allowed — gets moved to Marketing (more expensive).
- **Multiple agents on free app**: doesn't work. You need the **multi-device feature** or the API.
- **Meta blocks**: spam, inappropriate content and low message quality may cause Meta to limit your number.

## WhatsApp Business vs competitors

| Feature | WhatsApp Business API | Instagram DM API | SMS |
|---|---|---|---|
| Read rate | 98% | 70% | 95% |
| Cost per message (US) | $0.005-0.025 | $0.005-0.020 | $0.05-0.10 |
| Rich media | Yes (video, PDF, buttons) | Yes | No |
| Pre-approved templates | Required | No | No |

For most cases in the US, WhatsApp is the most efficient channel because nearly everyone has it installed.

## Why use an official provider over "unofficial WhatsApp"

There are tools promising to use WhatsApp without being an official BSP. Don't. Why:

- **Meta bans numbers** using unauthorized clients
- You **lose history** and get no support
- No **verified green badge**
- Permanent number ban risk

Official providers like [Zavu](/en/whatsapp-business-api), Twilio, MessageBird and Infobip follow Meta's protocol and provide continuity guarantee.

## Conclusion

WhatsApp Business is, practically, two products: a **free app** to start and a **paid API** to scale. Most US companies start with the app and move to the API when they hit ~100 conversations/day or need CRM integration. Providers like Zavu make that migration in hours with no setup cost. If you still handle customers manually with low volume, stay on the app — it's genuinely good. When volume grows, [the API awaits](/en/whatsapp-business-api).
