Now, let’s dive into the chatbot development process.

How to Develop a Chatbot

You can try to develop a chatbot without outside help. For that, you can use one of the bot engines such as Chatfuel or Rebotify that work on a subscription basis. However, for a custom-made chatbot, you will need to hire a chatbot development company.

There are several types of chatbots. They differ by the complexity, features, and cost of development. Below we share three main kinds of chatbots so you could pick the right one for your business.

The Types of Chatbots for E-Commerce
1.Script Bots. This is the simplest type of chatbots. Such bots operate on the base of predefined commands or scripts. They are programmed to recognize some words and answer basic questions. Nowadays, this is the most popular type of e-commerce chatbots. However, they aren't very flexible. Some online shops integrate bots with Natural Language Processing (NLP) technology to make interactions with customers more natural.

2.Smart bots. These chatbots are powered by AI (Artificial Intelligence)They provide a more positive user experience since they interact with customers in a human-like way. Still, such bots are not perfect. Their work is not fully automated, and they need human intervention to be able to answer specific customer inquiries.

3.Intelligent Agent. This is the most advanced type of chatbots. They combine machine learning and AI technologies, which makes them entirely self-sufficient. The great examples of such bots are Amazon’s Alexa, IBM Watson, and Siri.

For our clients, we recommend using the script chatbots. They are useful in most cases, from product recommendations to customer support, while costing less compared to chatbots with AI. Still, the choice is up to you and your business needs.

Define E-Commerce Chatbot Features

On this stage, you need to decide the purpose of your future chatbot since there are many options. Your future chatbot could perform as:

Alternatively, all of these purposes can be used in one chatbot since this technology has endless business use cases.

Below we share the most popular tasks performed by a chatbot on e-commerce websites. Please read it and pick the most useful one for your future chatbot feature list.

Let’s move further.

Design a Conversational Interface

One of the chatbot development stages is to design of a conversational user interface or CUI. This particular type of interface mimics human interaction between the online shop customer and the online shop. Its main task is to simplify the customer interactions with the online store using messengers. A conversational interface is critical not only for the look and feel of your e-commerce chatbot but also for the natural flow of the conversation.

The conversation interface of your future chatbot should also include options like “Yes,” “No,” and others to help the dialog process. Also, a good conversational UI should manage user expectations and imply the validation of user input data. Additional great advice is to include words such as “Sure,” “Got it,” and, “Thank you” to make your future chatbot sounds like a human.

The conversation with your chatbot should be user-initiated. This way, allow users to block the conversation easily at any time. A convenient exit experience usually includes the contact information. If your customer needs to speak with a human in case of complex requests, provide him with the ability to contact the available human service agents.

Let's look at some examples. Conversational interfaces come in two formats. The first one is a voice assistant like Siri or Alexa. The second one is chatbots. Their primary goal is to receive commands from a user in the form of conversations and carry the interaction forward in a human manner. So the customers receive a more “human” experience by using a large number of possible scenarios.

There is a vast difference in how a chatbot and web app respond to user input. In the example below, we see how standard healthcare apps behave when the user is trying to login unsuccessfully.

As we can see, the app provides an error message without any explanation about what went wrong. Moreover, it does not offer any options to help or to contact a human.

At the same time, because of their conversational nature, chatbots generally provide more information and try to help users. Therefore, they are more emphatic.

When creating a conversational interface for your online store, it is essential to write a script that interprets user answers. Designers should also pay attention to both easy to handle close-ended conversations and open-ended conversations so that chatbots can communicate with customers more naturally.

Choose a Chatbot Development Platform

If you decided to adopt chatbots for your online store, you also need to be aware of chatbot building platforms. We have compiled a list of three popular platforms, used by our developers for building e-commerce chatbots.

How to Develop a Chatbot: a Step-by-Step Guide

Since you have decided to revolutionize the customer experience that your online shop offers, welcome to this part of the article.

Below we describe steps required for the chatbot development. Knowing the whole process would help you be on the same page with the development team.


The backend of the chatbot allows handling messages received from several channels and processing them with NLP (natural language processing). The backend of a chatbot connects with the conversational intelligence and the online shop system to make the conversation happen.


On this step, you should define places where your future chatbot will communicate with your customers. The location can be your online shop, or Skype, Facebook and even Twitter. Still, it is essential to choose the right channel. Otherwise, you are risking to alienate and disappoint your customers, who are expecting specific functions.

At this stage, developers create modules to integrate a chatbot’s back-end with each of the channels you have selected. Once the developer has established the selected channels, the next step is to determine some of the UI elements.

Natural Language Processing

Once the development team finishes with the backend and the channels are established, your e-commerce chatbot can send and receive messages. The next step is to integrate the NLP (Natural Language Processing) services is to enable your chatbot to extract entities and intents out of the customer messages. Most NLP services allow manual input of the entities and their values to the UI. At this stage, the e-commerce team maps entities to specific objects that already exist on your e-commerce systems, such as Products, Catalog, Contacts, and others. The development team also implements some business logic validation rules on top of the data extracted.

Conversational Intelligence

Conversational Intelligence, developed on the base of NLP entities and intents, is a map of your customer journey. Here, developers create the algorithm for each particular conversation together with simple navigation. In some cases, they develop simple decision trees, slot-based conversation, and state workflow. However, when the clients need a more advanced solution, they apply a deep learning algorithm to control the conversation.

Conversational UI

As we said, the conversational interface deals with a conversation of a chatbot with your online shop customers. To provide your customers with good user experience, it should be similar to a natural human conversation, simple and has intuitive interfaces. For that, the chatbot developers think on the dialog flow and how it solves user’ problems.

The development team should adopt the conversational UI of your future e-commerce chatbot to the preferences and needs of different users. Moreover, all the user groups should use a chatbot without a need to learn anything. The team could improve the chatbot conversational UI by offering interactive buttons, carousels, message menus, and cards. Such elements also provide customers with the better presence of the necessary information.

How to Train a Chatbot

Now you are going to discover how chatbots learn and what chatbot training data is.

As we said, different types of chatbots handle data in different ways. While a rule-based chatbot has a limited set of functions and questions, an AI chatbot develops a growing collection of understanding and knowledge. Below we share tips on how to develop AI chatbot and train it so that a bot can study from previous examples over time.

As an example, let's consider a customer service AI chatbot. It needs to have an idea of the questions that customers are going to ask. Also, such chatbot needs to know, what it should answer to these questions. In this case, a customer service chatbot needs the data from the previous inquiries and the data from earlier correct answers. For that, you can use email chains, live-chat scripts, and website FAQs or email replies of your customers; this way would be training data for your e-commerce chatbot.

When we are hired for e-commerce chatbot development services, we receive the training data from our customers. To teach the chatbot, customers provide us with PDFs, spreadsheets and website FAQs. Then, our best chatbot developers turn these data into organized, labeled data, readable by chatbots. This way, chatbots receive the idea of what people are asking and how to respond to them.

Since we have finished with the different components of e-commerce chatbot development, let us look at what matters to our clients on a more complex level. It is time to discuss the cost and time of chatbot development.
