Multiple AI-powered services were running on disconnected scripts with no shared portal, no usage metering, and no self-service access. We built a unified SaaS platform that brought document processing, chatbot management, and API billing under a single authenticated dashboard.
The project involved consolidating several independent AI microservices into one cohesive SaaS product. Document analysis, chatbot interactions, and third-party API integrations each lived on separate codebases with no shared authentication, no centralized analytics, and no way to meter or bill for usage.
Deliver a production-ready SaaS portal that unifies all AI services under role-based dashboards, introduces token-based billing with automated invoicing, and enables fully automated document processing through OCR and AI extraction pipelines.
The portal was designed with two distinct experiences. End users get dedicated modules for each service, complete with file uploads, processed report downloads, and usage charts. Administrators access system-wide analytics, API call logs, and support tools from a separate dashboard without overlapping permissions.
The AI layer handles two distinct workloads. For documents, it converts uploaded PDFs into structured data by combining OCR engines with OpenAI Vision to extract fields like transaction dates, amounts, and account details. For conversations, it powers real-time chatbot interactions while tracking token consumption and cost per thread for accurate billing.
Get Started
Multiple AI services ran independently with no shared authentication, no common data layer, and no centralized way to monitor which user consumed what resources.
Uploaded documents varied widely in format, structure, and quality. Extracting accurate structured data required combining multiple processing techniques with AI-driven validation.
Every API call and document upload consumed compute resources, but no system existed to track consumption per user or charge accordingly.
The platform handled sensitive documents and conversation logs across multiple tenants. Each user's data had to remain fully isolated with role-based access at every layer.
Document processing, chatbot management, verification workflows, API integrations, and billing consolidated into a single authenticated platform.
PDF uploads are converted to images, processed through OCR, and analyzed by AI Vision to output structured data without any manual data entry steps.
Self-service checkout flow with automatic token crediting, per-call deductions, and invoice emails triggered on every successful purchase.
Every endpoint hit is recorded with payload details, cost calculation, and user attribution, giving both admins and customers full consumption visibility.
Our Custom AI Development Services help you build intelligent systems designed around your specific workflows, not off-the-shelf templates.
Multi-step extraction pipeline converting PDFs to images, running OCR, and applying AI Vision for structured data output in a single upload flow.

Token economy with self-service checkout, automatic balance updates, per-call cost tracking, and payment records with downloadable invoices.
Branded API explorer with visual endpoint testing, enabling partners to integrate document, chatbot, and verification services independently.

Mehul and his team were very professional and their work was to the highest standard. the website was done exactly how I wanted and he provided training for me to work each step behind the scenes.
