How Much Does It Cost to Build a
AI Chatbot for B2B Software?
AI chatbot pricing reflects LLM infrastructure costs, knowledge base complexity, and the safety and moderation layers your use case requires. Greta builds chatbots that stay on topic, respond accurately, and integrate with your product surface without feeling bolted on.

What affects the price of a ai chatbot for B2B software companies
Business software products with complex buying committees and long sales cycles — which shapes which of these factors apply most directly to your build.
LLM selection and API cost structure — GPT-4o, Claude, or Gemini each have different pricing and capability trade-offs
Custom knowledge base — document ingestion, chunking strategy, vector embeddings, and retrieval quality
Conversation context management — session memory, multi-turn context windows, and state persistence
Safety and moderation layers — prompt injection defense, topic boundaries, and output filtering
Integration surface — standalone widget, in-product sidebar, API endpoint, or Slack/Teams deployment

How Basic, Standard, and Advanced differ
Feature Depth
LLM chat with a system prompt. No custom knowledge base — model answers from training data only.
Customization
Configurable persona and response style. No branded UI beyond basic color matching.
Performance
Standard API response latency — typically 1–3 seconds. No streaming optimization.
Scalability
Works for low-volume use. API costs scale linearly with usage — no optimization layer.
Feature Depth
RAG pipeline with your documents ingested, chunked, and retrieved contextually. Multi-turn conversation memory.
Customization
Branded chat UI with configurable fallback responses, topic restrictions, and escalation paths.
Performance
Streaming responses for perceived speed, optimized retrieval with re-ranking, and conversation caching.
Scalability
Handles hundreds of concurrent users. Vector database scales with knowledge base growth.
Feature Depth
Agent-style chatbot with tool use — can query your database, trigger workflows, and retrieve real-time data.
Customization
Full UI integration within your product, configurable per user role, and white-label API for embedded use.
Performance
Retrieval latency under 200ms, streaming with fallback handling, and usage analytics per query.
Scalability
Enterprise infrastructure with rate limiting, usage metering, A/B testing on prompts, and model switching.
Why B2B software teams build with Greta instead of agencies or freelancers
We build RAG pipelines that retrieve accurately — not chatbots that hallucinate confidently about your product
LLM infrastructure cost optimization is built in from the start — caching, chunking, and model selection affect your monthly bill significantly
AI-assisted development accelerates the non-AI parts of the build — leaving more time on the retrieval quality that actually determines user satisfaction
We've shipped AI features across multiple product categories — we know which integration patterns users adopt and which feel like demos
Greta vs Freelancers vs Traditional Agencies
Freelancer
Cost
Low upfront, but retrieval quality and safety infrastructure are consistently underinvested
Speed
2–8 weeks, often with quality issues that require rework post-launch
Reliability
High variance — RAG pipeline quality depends heavily on the individual's LLM experience
Quality
Often produces a chatbot that sounds good in demos but answers inaccurately on edge cases
Traditional Agency
Cost
3–5× more, including AI strategy consulting and enterprise API procurement
Speed
12–24 weeks with security reviews, compliance sign-off, and phased rollout
Reliability
Consistent, but optimized for enterprise risk tolerance — not startup speed
Quality
Thorough and safe, but often over-engineered and slow to adapt as models improve
Greta
Cost
Fixed-scope pricing that includes RAG architecture, safety layers, and integration work
Speed
Days to weeks — we build on proven LLM infrastructure patterns, not from scratch
Reliability
Consistent — AI product architecture is a core Greta competency
Quality
Accurate, safe, and integrated naturally — not a chatbot widget overlaid on a product that doesn't need it
Standard delivery in 23 days

What a standard ai chatbot means for B2B software companies
For B2B Software products, an AI chatbot creates value only when it answers accurately about your specific context — not when it generates plausible-sounding responses from general training data. At standard scope, we prioritize retrieval quality and safety over feature volume.
Industry Context
Business software products with complex buying committees and long sales cycles
Shortening the sales cycle while increasing the average contract value
Target Outcome
shorter time-to-revenue with higher ACV
A standard scope ai chatbot delivers the core functionality needed to move toward this outcome — without the cost or timeline of a full-scale build.
