Choosing a Chatbot Development Partner That Delivers Results

Selecting a chatbot development partner should not only be based on their coding knowledge but also on their knowledge of your business objectives and how to create a bot that assists in imparting true value. Look out for the following:

1. Define Your Chatbot’s Purpose

Specify what you expect your chatbot to do, such as answering frequently asked questions or qualifying leads, or taking users through the onboarding experience. Defined objectives make vendors suggest appropriate strategy and tech.

2. Look for AI & NLP Expertise

Basic bots work on scripts, however intelligent ones are aware of context and intent. Select the company that has worked with NLP, ML, AI models and either Amazon Lex, Microsoft Bot Framework, or GPT-based tools.

3. Demand Customization and Integration

Don’t use cookie-cutter bots. Make sure the solution is able to connect with your systems (such as HubSpot or Microsoft Dynamics) and operate on multiple channels such as web, WhatsApp, or mobile apps.

4. Focus on User Experience

A quality bot should be inviting and conversational. Inquire about how the vendor designs, tests, and deals with confusion or edge cases when talking to users.

5. Check for Ongoing Support

A chatbot requires an update. Make sure that the company implements post-launch services, such as performance monitoring, fine tuning AI models (especially when you hire AI developers), and optimization of the flow.

6. Ensure Data Security

Your chatbot might be dealing with sensitive information. Select a vendor that follows guidelines (like GDPR or HIPAA) and employs robust encryption and authentication.

7. Review Proof of Success

Request references, client reviews and case studies. Seek quantifiable outcomes, such as an increase in conversions or a decrease in support tickets.
