How to Develop a Chatbot and How Much will it Cost?

Chatbots are revolutionizing how businesses across various industries interact with customers. The technology has expanded beyond simple chat autoresponders to become a full-fledged virtual assistant that can perform various tasks, improving customer service, streamlining operations, and even increasing sales. If you're considering developing a chatbot for your business, it's important to understand the development process and the associated costs. Here's a comprehensive guide to help you get started.

What is a Chatbot?

A chatbot is a software app created to simulate human conversation. It can interact with users via text or voice, providing answers to queries, performing tasks, and even engaging in casual conversation. Some chatbots operate based on decision trees, following a linear path of responses based on predefined rules and patterns, while others utilize machine learning algorithms to process and interpret user inputs and generate more nuanced replies. Some of the first examples of well-known chatbots that come to mind are ChatGPT, Apple's Siri, Amazon's Alexa, and ChatGPT.

In most cases, a chatbot integrates into websites, social media channels, messaging apps, or other supported platforms and can serve a wide range of purposes across different industries. Healthcare, e-commerce, banking, and even government are those sectors that are already successfully using chatbots for customer support automation and user engagement.

Which sort of Chatbot fulfills your business requirements?

A chatbot can provide a diverse range of functionalities and capabilities, and choosing the chatbot type depends on your needs and customer expectations. Here are some of the primary types that fulfill different business requirements:

Rule-Based Chatbots are the pioneers in the chatbot world. They operate on predefined rules and patterns using if/then logic for personalized interactions. While they're easy to set up and quite effective for handling straightforward, predictable interactions, they might struggle with complex or ambiguous queries. Best for businesses with clearly defined workflows.

Menu or Button-based Chatbots don't give answers like rule-based chatbots but rather guide users through options, buttons, or menus. They are user-friendly, easy to implement, and require minimal programming and maintenance. They are best for basic customer interaction and standard information.

AI-Powered Chatbots leverage ML algorithms and NLP for dynamic, context-aware responses. They excel in handling dynamic, unpredictable conversations as they can grasp the context, understand the sentiment, and even offer recommendations based on user behavior.  Additionally, they learn from interactions, improving responses over time. Best for comprehensive customer support, personalized marketing and engagement, or complex query resolution.

Voice Chatbots interact with users by understanding and responding to voice commands. They are becoming increasingly popular in customer service and virtual assistant apps and are suitable for environments where typing is impractical. Best for hands-free interaction and users preferring voice and requiring multitasking.

Hybrid Chatbots, also referred to as Scripted chatbots, combine elements of different types to use the strengths of each. They follow a script or decision tree but are also capable of some level of natural language understanding for more complex interactions, offering a well-rounded user experience. They are best for scenarios where a balance between structured interactions and flexibility in conversation flow is crucial.

Why do you need a Chatbot for your business?

So, if you are planning to develop a chatbot, deciding on its use cases is the first thing to do: whether it is to relieve customer service agents, offer uninterrupted support, or enhance user experience with, say, recommending better products.

What are the Main Steps to Develop a Chatbot?

1. Define the Purpose and Goals

Your chatbot is a unique type of software, and developing it is a complex process. Your requirements and business goals are the first and most significant factors influencing the development path and, consequently, the price. So, before diving into development, clearly define what you want the chatbot to achieve. Identify the primary functions, target audience, and the type of interaction it will handle. Remember that any chatbot can be created to serve different purposes than only handle message replies, i.e., it can be created with multiple functions and capabilities. Common goals include customer support, lead generation, FAQ chatbot, marketing, appointment booking, information collection, etc.   

The defined goals and uses of the chatbot will determine chatbot features that influence the development difficulty and scope. Thus, for instance, an AI-driven chatbot, like Sephora's, and a simple FAQ bot are two different development scopes with distinct chatbot costs. Implementing machine learning, data analysis techniques, predictive analytics, or integrations with existing systems requires more development time and expertise, increasing the budget.

2. Choose the Platform

The number of supported platforms also influences a chatbot's cost. If you want to cover more platforms, it will obviously increase your final payment. Decide where your chatbot will be deployed. Popular platforms include:

Messaging Apps: Your chatbot can be deployed on messaging apps such as Instagram, Facebook Messenger, WhatsApp, or Slack. It can work with one platform or multiple platforms simultaneously. Integrating with more platforms typically increases costs due to the need for additional development and maintenance.

Website Chatbots: These chatbots are embedded in your website and are primarily used for customer service and answering inquiries. They typically require additional integration with website backend systems such as CRM or support ticket systems, which can increase development costs. In addition, ongoing support and maintenance are required to ensure that the chatbot operates effectively and stays up to date with any changes to the website or underlying systems.

Internal Business Use: Chatbots designed for internal use within an organization can automate common procedures such as sick leave requests, shift changes, project monitoring, and more. The cost of developing such a chatbot varies based on the complexity of the internal operations it will handle.

Voice Assistants: Chatbots can also be integrated with voice assistants like Amazon Alexa or Google Assistant. Depending on the required functionality and the sophistication of voice recognition and processing capabilities, these integrations can be more complex and expensive.

3. Select the Development Approach

Chatbot Builders: Various low-code or no-code third-party platforms such as Chatfuel, Tars, ManyChat, or Flow XO offer drag-and-drop features and pre-built templates that enable building your own chatbot with little technical experience and minimal upfront investment. This approach is ideal for those who are on a budget or seeking a basic chatbot solution without advanced features like AI integration.

Subscription-based Platforms: These platforms provide ready-made solutions with robust features and minimal setup aka leasing chatbot software as the ready service. Ideal for businesses seeking quick deployment and ease of use. While users of chatbot builders are responsible for building and customizing their chatbots themselves, subscription-based platforms often provide more comprehensive solutions where the provider manages much of the setup and maintenance. It can include advanced features like AI integration, extensive support services, and regular updates, making them more suitable for businesses looking for out-of-the-box solutions without the need to build or maintain the chatbot themselves. Some of the most popular providers range from free options like HubSpot (for basic features) to solutions from Drift, Intercom, LivePerson, Zendesk, Tidio, and DenserAI, which offer more advanced features and cater to various needs.
