Why create your own WhatsApp chatbot?

Using a WhatsApp chatbot transforms how you can interact with customers by automating conversations and reducing workload. It's not just a time-saving tool but also aids in effectively generating leads and guiding customers through the marketing funnel.

The result? More breathing space for tasks that truly matter and a more efficient customer communication process.

What is a WhatsApp Bot?

A WhatsApp Bot, integrated with WhatsApp, is an automated communication system that uses AI to conduct real-time conversations, generate responses and answer customer service inquiries. When your business has a WhatsApp chatbot, customers can easily reach out via WhatsApp and receive an automated reply, just like when they send a message via the website chatbot.

It's more than just a customer service tool; it's software that makes you accessible on WhatsApp and can be deployed to bolster your team, engage in more conversations or support other business goals.

How much does a WhatsApp chatbot cost?

Downloading the WhatsApp Business app is free for both iOS and Android devices. Creating a business account on WhatsApp is easy, but note, it is not possible to use one number for both a private and a business account.

If you do not want to use your private number, you can consider purchasing another device with a new SIM card or using the WhatsApp Business API. Although the app is free, it does have some limitations; some functionalities are not accessible.

For full access to all WhatsApp Business features, the API is a good option. However, the costs for using the WhatsApp Business API can vary. Connection fees can go up to €1000 with some providers, while providers like Watermelon do not charge connection fees.

As of February 2022, WhatsApp has formally implemented a dialogue model for the official WhatsApp Business API. Both Template messages and Session messages are now billed based on the number of dialogues, depending on whether the message is initiated by the business or the user.

Primarily, the initial 1000 conversations started by users are free!

Note: Conversations initiated by users are also recognized as service conversations. There are no costs associated with this type of conversation if your business does not respond to the users.

Subsequently, the costs for each type of dialogue depend on the country where your business is located, the following rates apply for the Netherlands in euro's:

  • Marketing: 0.184 (initiated by the company)

  • Utility: 0.092 (initiated by the company)

  • Authentication: 0.083 (initiated by the company)

  • Service: 0.103 (initiated by the user)

For the United Kingdom, the following rates apply in British pound:

  • Marketing: 0.082

  • Utility: 0.046

  • Authentication: 0.042

  • Service: 0.045

Marketing Conversations
As the name suggests, Marketing conversations are conversations initiated by companies to promote a product or service to customers. You can send your registered customers relevant offers, good deals, or information about products being back in stock.

Utility Conversations
Under the Utility category are initiated by companies and often relate to transactions. This includes information about purchases, confirmations, post-purchase notifications, and periodic invoice summaries for customers who have registered for this.

Authentication Conversations
With Authentication conversations, security is essential. Thanks to authentication templates, it is possible to verify users with one-time passwords at various times during login or verification procedures, such as when creating an account, account recovery, and other situations where identity confirmation is necessary.

Important to know: Every conversation started by companies that do not fall under Authentication or Utility is categorized as a Marketing conversation.

Service Conversations
All conversations that are initiated by users, often to resolve a customer inquiry.
