Chatbots are taking a toll over mobile apps and
challenging its existence. With the rapid
adoption of chatbots by leading companies,
majority of business leaders are thinking of
building one. If you are one among them and
wondering whats the exact cost to build a
chatbot application?




To start with, lets understand the number of
stages involved in chatbot application
development.

Managing incoming stream of messages with backend
development
Creating modules to integrate with each channel
Integrating Natural Language Processing (NLP)
with readymade APIs
Creating natural humanly replies with
Conversational Intelligence
Aligning chatbot conversations with the
commercial and core purpose of development
Having understood this, lets move on to know how
much time, resources and effort is involved at
each stage.

Creating Channels and Integrating Modules

• With a powerful backend system, developers move
  on to the next stage of chatbot application
  development, i.e. creating modules for
  integration with each channel.
• Chatbots UI should integrate quick reply buttons
  and other visuals essential for smoother
  conversations with the users. The best example is
  Facebook Messenger chatbot that uses JavaScript,
  HTML and CSS for conversational UI by means of
  WebView.

Natural Language Processing (NLP) Services

• The main part of chatbot application development
  is the integration with NLP services that allows
  bots to engage in natural and humanly
  conversations with users. Developers do not need
  to write an altogether new NLP algorithm they
  can use from existing APIs of Google, IBM,
  Microsoft and Facebook.
• Integration of NLP service with API is a
  time-consuming task as it requires training of
  different entities and intents. Developers are
  required to map entities to specific objects of
  the existing system such as names, identifiers or
  products. In order to authenticate users input,
  developers need to implement business logic and
  authentication rules for validating the received
  data. This validation requires developers to code
  in Node.js and .NET.

Making Conversationally Intelligent Chatbot

• This stage of chatbot application development is
  the most time consuming and requires intense hard
  work of developers. They need to code the chatbot
  such that it generates natural replies just like
  humans and engages in meaningful conversations as
  per NLP intents and entities. The only way to
  make a chatbot as humanly as possible is to keep
  iterating and improving it.

Ensuring Integration of Chatbots with Existing
Systems

• The end goal of developing a chatbot is to
  present users with a customer service agent that
  assists them in each and every stage. Chatbots
  must serve the commercial purpose of development,
  i.e. they must be able to assist users in getting
  the task done, be it booking flight tickets,
  shopping for the right size apparel, ordering
  food from restaurant or anything else as per the
  nature of work of business.

Control Panel

Control panel is used to track the conversation
history of chatbot, number of users and error
logs. Control panel is required to measure bots
performance. Setting up a database for chatbots
may take up to a weeks time, but its worth it.
Developers are using long code blocks for
building control panel using Node.js Angular 2
and .NET.

Final Notes
Considering the smooth development life cycle,
the overall time taken for building a chatbot
application is around 586 to 590 business hours.
The approximate cost to build a chatbot
application ranges anywhere between 24580 and
30920 as the level of expertise and experience
of developer working on the project.
