The Multi-Tenant Support Challenge

SaaS companies and multi-brand e-commerce operators require AI agents to resolve customer questions from proprietary manuals and order data, capture and qualify sales leads, and book CRM appointments. However, generic bots suffer from high risks: hallucinating returns policies, leaking data between competing tenant accounts, and incurring unsustainable API bills without per-customer usage limits.

Tenant-Isolated Knowledge & Metered Billing Architecture

We architected a unified platform combining tenant-scoped vector search, deterministic tool execution, and real-time usage metering. Retrieval is strictly filtered by tenant before vector ranking, and every generated response cites source page references. Scoped tool actions enable agents to inspect order status or schedule CRM demos while money-moving actions require confirmation. Model routing dispatches routine questions to lightweight models with prompt caching, while complex inquiries utilize frontier models. All token consumption is metered per tenant with automated Stripe overage billing.

Production Architectural Guarantees

  • Mathematical tenant isolation filtering all vector embeddings and order records prior to semantic ranking
  • Verifiable source citation enforcement with automated fallback when retrieval confidence is below threshold
  • Scoped tool execution for order lookups, CRM ticket creation, and calendar booking with prompt-injection defense
  • Tiered model routing with prompt caching cutting operational token expenditure by over 70%
  • Real-time usage metering integrated with Stripe billing for automated subscription quotas and overage charges
Live Multi-Tenant Proof: Tested with synthetic multi-tenant test suites proving cross-tenant retrieval attempts fail closed.

“
★★★★★5.0 Verified
✓ Zero-Hallucination SLA • Multi-LLM Swarms

“Vijay and the SHIVAM ITCS AI team didn't just execute the project - they elevated our entire platform. Their ability to architect complex multi-agent state machines, eliminate latency bottlenecks, enforce zero-hallucination guardrails, and create an intelligent multi-LLM orchestration layer was extraordinary. The final delivery was resilient, battle-tested, and far beyond expectations. One of the strongest AI systems engineering teams in the industry.”
