We gather market requirements for Hal to discover who it’s going to help, and how.

We identify Hal’s features and functionality, so it’s equipped to give your customers the benefits they need.

Hal is assigned conversational scripts to make sure its conversation abilities are similar to a real human’s.

We begin to engineer and design your new bot.

To develop Hal, we’ll cycle between coding and testing, fine-tuning it so its capabilities approximate real human conversation.

When it’s done, Hal will have been thoroughly tested for quality assurance.

Finally, once Hal is built, it will be deployed to a stable, hosted environment and prepared for submission to various app stores.

We take Hal through the rigorous approval process for each messaging platform.

Once Hal is published, it will be monitored, using actual conversational scripts, to make sure it’s doing exactly what was intended.

It’s time to let everyone know about your new bot.

Finally, we’ll watch how Hal does in conversation to see if there’s anything we can work on to improve.

The end result is a full-function, highly-capable chatbot that will make money for you, while making your customers appreciate your service.

It’s what your customers want

They’ll appreciate the convenience and pick you over the competition, every time.

Because they have easy access to your services directly through messaging apps like Facebook Messenger, Kik, or Slack, they’ll have every reason to pick your services over the competition’s.

Plus, they’ll enjoy instant no-hassle customer service.

Frequently Asked Questions

Chatbots are artificial intelligence systems that we interact with via voice or text interfaces. To develop a chatbot, it’s important to map out the conversational flow (i.e., the questions and follow-up questions customers ask). Next, it’s necessary to deep dive into existing conversations and crowdsource chat collections. After this, the developers should infuse personality into the bot by either using colloquialisms or a more laid-back communication style, depending on the company or brand. Lastly, developers must use prototyping tools to test the feasibility and usability of the chatbot and fix errors before finalizing it permanently.

The cost of developing a chatbot largely depends on whether you want to build it in-house or hire an agency for it. Hiring an agency frees you and your team up for your core business projects. Capital Numbers provides you multiple pricing options to build your chatbot. You can either go for the fixed-price contract that starts at $20 per hour. Or you can hire a dedicated developer (starting at $2400 per month) to build your bot. We sign an NDA before starting any project to maintain strict confidentiality of your business-critical data.

This depends on the type of bot that you are planning to build, for example, customer service bot, website bot, registration bot, transaction bot, lead generation bot, etc. The time taken to build a bot also depends on factors such as backend development, integration of third-party modules, integration of NLPs with ready-made APIs, using conversation intelligence to create human-like replies, and aligning bot conversations with core development purposes.

The chatbot development services that we offer include chatbot architecture, conversational design, natural language processing (NLP), custom chatbot development, integration with enterprise-grade systems, chatbot testing and deployment.

Yes, you can hire qualified and highly-skilled chatbot developers from us (starting from $2400 per month). If you want, you can manage your developers directly, assign tasks, and review the output. Alternatively, we are happy to offer a free-of-cost Project Manager who can act as your single point of contact while managing multiple developers on your behalf.

To check the authenticity of a chatbot development company, you can check its client testimonials on 3rd party platforms such as Clutch and GoodFirms. You should also have a look at its Google reviews, awards, certifications, client partnerships, and social media profiles. This will give you a clear perspective on the company’s reputation and position in the market.
