AI chatbots and agents for customer service

At 150 Por Ciento we build chatbots that resolve, not ones that stall. Agents connected to your catalog, your policies and your systems, answering from real information, knowing when to hand the conversation to a person, and measured by cases closed.

Where your customer already is: WhatsApp, your website, or your internal channels.

In short

Design and development of AI chatbots and conversational agents for WhatsApp, web and internal channels, connected through RAG to the company's real data, with human escalation and resolution metrics.

What we solve with chatbots and conversational AI

The problem is rarely “we don’t have a chatbot”. It’s this:

  • Support teams answering the same question hundreds of times a day
  • Customers waiting until Monday for something answerable in ten seconds
  • Decision-tree bots that only teach customers to type “talk to an agent”
  • WhatsApp conversations lost, with no traceability or CRM record
  • Generic AI chatbots inventing policies and prices that don’t exist
  • Internal staff losing hours searching through manuals and procedures

A bot that doesn’t resolve doesn’t save work: it postpones it and annoys the customer on the way.

Why a well-built AI chatbot doesn't invent answers

The fear of hallucination is justified. Here’s how we prevent it:

  • RAG (retrieval-augmented generation): the agent answers only from your documents, catalog and policies — not from what the model “believes it knows”
  • Bounded scope: we explicitly define what it may and may not assert; outside that perimeter, it defers
  • Human escalation: on doubt, high value or an upset customer, the conversation goes to a person with full context
  • Traceability: every answer is logged with the source backing it, auditable

The difference between a useful assistant and a dangerous one isn’t the model: it’s the design around the model.

What kind of solutions we deliver

  • Customer service chatbots on the WhatsApp Business API
  • Website assistants connected to your catalog and inventory
  • Internal agents answering from manuals, procedures and knowledge bases
  • Transactional bots: scheduling, order tracking, quoting
  • CRM and help desk integration so nothing gets lost
  • Rescue of existing chatbots that don’t resolve or that hallucinate

If the project grows toward deeper automation, the same team covers it from applied artificial intelligence.

How we do it

1. Conversational discovery
  • We analyze your real conversations to see what actually gets asked
  • We identify what share can be safely automated
  • We define the bot’s limits and the escalation rules
2. Knowledge base
  • We consolidate catalog, policies and procedures as a single source
  • We build the RAG architecture with vector search
  • We define the brand tone and handoff messages
3. Development and testing
  • Integration with WhatsApp, web and CRM
  • Adversarial testing: we actively try to make it hallucinate before a customer does
  • Pilot on limited real traffic with human supervision
4. Production and improvement
  • Conversation monitoring and resolution rate
  • Knowledge base tuned against what the bot couldn’t answer
  • Scope widened gradually based on results

Frequently asked questions

How much does it cost to build an AI chatbot?




A support chatbot connected to your information starts at 3,000 USD. Agents with transactional integrations to CRM, inventory or scheduling usually run between 8,000 and 25,000 USD. On top of the project cost sits the model’s API usage, which is variable and fully transparent.

How do you stop the chatbot from making things up?




We use RAG: the agent answers only from your documents and catalog, not from the model’s memory. We also explicitly bound what it can assert and force it to hand off to a human when the question falls outside that perimeter. Before going live we put it through adversarial testing.

Does it work on WhatsApp?




Yes, and it’s usually the main channel in Latin America. We build on the official WhatsApp Business API, with your verified number and Meta-approved templates.

Will the chatbot replace my support team?




No — it takes the repetitive volume off them. Typically it resolves most frequent queries and hands off the rest with context, so your team spends its time on the cases that genuinely need a person.

How long does implementation take?




A support chatbot with a knowledge base takes 3 to 6 weeks. An agent with transactional integrations can take 2 to 4 months.
