Conversational access to approved company knowledge

Enterprise AI Chatbot Development with RAG

Build enterprise RAG chatbots for customer support, employee assistance, and product guidance using the information your organization approves. Conversational design covers follow-up questions, relevant conversation context, and links to supporting documentation. Define when the chatbot should ask for clarification, acknowledge insufficient evidence, or transfer a request to a person. Integration can include authentication, scoped customer context, and existing support workflows. Evaluate answer support and task completion using representative conversations, with separate testing for each supported language rather than assuming consistent performance across languages.

Chatbot Capabilities

  • Customer support and employee assistance
  • Follow-up questions and conversation context
  • Answers linked to approved source material
  • Authenticated and permission-aware access
  • Human handoff and clarification workflows
  • Multilingual configuration and language-specific testing

Organized documentation with a defined content lifecycle

AI Knowledge Base Development

Create an AI knowledge base that makes approved documentation searchable while preserving the structure and ownership of the underlying content. Assess PDFs, SOPs, manuals, and internal articles to define parsing, chunking, metadata, and indexing rules. Source references help users inspect supporting passages, while version handling and synchronization account for updated or retired documents. Establish content owners and review procedures so the knowledge collection remains maintainable. Test common employee questions against reference material to identify extraction problems, missing guidance, and retrieval gaps before rollout.

Knowledge Base Scope

  • Document inventory and content readiness assessment
  • Parsing, OCR, and extraction validation
  • Chunking, metadata, and source references
  • Version, duplicate, and deletion handling
  • Content ownership and review procedures

Coordinated retrieval and research with defined controls

Multi-Agent RAG Systems

Design multi-agent RAG workflows when a task benefits from separate retrieval, research, comparison, or review responsibilities. Define each agent’s tools, information access, handoff rules, and completion criteria before introducing orchestration. Suitable workflows may include gathering evidence from multiple sources, comparing findings, and preparing a response for review. Start with a simpler pipeline where it meets the requirement, since additional agents introduce latency, cost, and debugging complexity. Apply execution limits, traceable intermediate results, and human approval for consequential actions.

Workflow Capabilities

  • Task routing and specialist retrieval agents
  • Multi-source research and evidence comparison
  • Scoped tools and agent access boundaries
  • Traceable handoffs and intermediate outputs
  • Execution limits, retries, and failure handling
  • Human review and action approval checkpoints
Multi-agent RAG systems illustration — THE TISA

Extraction, classification, and document-grounded analysis

AI Document Intelligence Solutions

Build document intelligence workflows that classify files, extract defined fields, and summarize relevant content for review. Combine document parsing and structured extraction with RAG where users need to ask questions across files and inspect supporting passages. Assess scanned pages, tables, and complex layouts using representative samples before defining coverage. Validate extracted values against schemas or business rules and route exceptions to reviewers. For sensitive legal, medical, or financial material, agree on access, retention, and review requirements; generated summaries support qualified review rather than replace professional judgment.

Document Processing Capabilities

  • Document classification and routing
  • OCR and layout-aware content extraction
  • Structured field extraction and schema validation
  • Source-linked summaries and cross-document questions
  • Business-rule checks and exception queues
  • Human review and correction tracking

01 / 06

Documents & policies

RAG document search for PDFs, manuals and SOPs

Make policies, product manuals, SOPs, and business documents accessible through natural-language search. Document-based RAG retrieves relevant passages to help employees understand procedures, locate requirements, and review exceptions, with references to the original files. Implementation includes assessing document layouts, extracting text, and organizing content into searchable sections while preserving useful context.

Information to retrieve

  • Policy clauses, eligibility rules, and exceptions
  • Product specifications and troubleshooting instructions
  • Operating procedures and compliance guidance

Implementation consideration

Scanned PDFs may require OCR, while tables and complex layouts need additional parsing. Version metadata, section references, and retrieval testing help assess whether answers use the appropriate document and passage.

Documents & policies RAG knowledge source — THE TISA

02 / 06

Knowledge repositories

Enterprise knowledge search across internal wikis

Connect internal wikis and knowledge bases to help employees find guidance across SharePoint, Confluence, Notion, and other repositories. An enterprise RAG application can retrieve relevant pages, combine supporting passages, and link answers to their sources. Repository integration considers page structure, content ownership, and access permissions so teams can search distributed knowledge through a shared interface.

Information to retrieve

  • Team documentation and technical reference pages
  • Employee onboarding and troubleshooting guides
  • Published knowledge articles and internal FAQs

Implementation consideration

Permission-aware retrieval requires mapping source access rules to application users. Synchronization should account for edited pages, deleted content, and permission changes, with retrieval checks against representative employee questions.

Knowledge repositories RAG knowledge source — THE TISA

03 / 06

CRM & support knowledge

Customer context for sales and support assistants

Help authorized sales and support teams retrieve account context, approved support articles, and relevant historical resolutions from CRM and service systems. A RAG-powered support assistant can bring supporting information into a response draft or internal search result, with links back to the underlying records. The scope should distinguish reusable support knowledge from sensitive customer information and outdated case notes.

Information to retrieve

  • Account details available to the requesting user
  • Approved support guidance and documented resolutions
  • Relevant case history and customer interaction records

Implementation consideration

Apply record-level and field-level access rules before information reaches the model. Minimize personal data, check whether historical resolutions remain applicable, and use scoped API queries when current account or case status is required.

CRM & support knowledge RAG knowledge source — THE TISA

04 / 06

ERP & business systems

Operational knowledge with business-system context

Connect process documentation, business rules, and selected ERP records to help operations, procurement, and finance teams investigate everyday questions. Retrieval-augmented generation can surface the guidance behind purchasing procedures, approval requirements, and operational workflows. When a question also depends on a changing business value, a scoped system query can provide current data alongside the retrieved explanation.

Information to retrieve

  • Operational reference records and process definitions
  • Procurement procedures and approval documentation
  • Business rules and exception-handling guidance

Implementation consideration

An indexed document should not be treated as the live source for inventory, balances, or transaction status. Define authoritative systems, access scopes, and freshness requirements; actions that modify records need separate authorization and validation.

ERP & business systems RAG knowledge source — THE TISA

05 / 06

Enterprise databases

Structured data retrieval alongside document search

Combine document retrieval with controlled database access when a business question needs both written guidance and structured records. A hybrid RAG application can use searchable text for explanations and validated queries for product details, service records, or current figures. The retrieval approach depends on the question, data structure, and level of precision required rather than treating every database record as a document.

Information to retrieve

  • Business entities and their relevant relationships
  • Product, service, and structured reference records
  • Current values supplied through approved queries

Implementation consideration

Use read-only credentials, allowlisted views or scoped APIs, and query validation. Exact counts, totals, and calculations should come from database operations, with access checks and query limits applied before execution.

Enterprise databases RAG knowledge source — THE TISA

06 / 06

Cloud file storage

Permission-aware search across shared business files

Make approved files in Google Drive, OneDrive, and Amazon S3 discoverable through a RAG-based search experience. Employees can locate project references, reports, and presentations using questions rather than remembering filenames or folder paths. Cloud storage integration covers file discovery, content extraction, and synchronization, with source links that let users open the supporting document in its original location.

Information to retrieve

  • Shared documents and departmental reference files
  • Project documentation and delivery materials
  • Approved reports, presentations, and archived guidance

Implementation consideration

Track file versions, duplicates, deletions, and access changes throughout synchronization. Define supported formats and indexing frequency, and expose source dates where they help users judge whether a retrieved document is still relevant.

From Discovery to Deployment

Our RAG Development Process

Our retrieval-augmented generation development process moves from source assessment to a tested application and operational handoff. Each stage produces a defined output, giving your team a clear basis for reviewing progress and approving the next step.

Evaluation starts with representative user questions during discovery. Those questions guide retrieval design, application testing, and release decisions as the system takes shape.

Agreed before implementation

Pilot scope, source access, acceptance criteria, deployment responsibilities, and the people who will review the results.

  1. Discovery & RAG Architecture

    Define the business workflow, intended users, and questions the application needs to answer. Assess whether retrieval-augmented generation is appropriate, then agree on access boundaries, hosting requirements, and integration dependencies. Establish a pilot scope with acceptance criteria for answer quality, response time, and operating cost before selecting the technical architecture.

    Deliverable: Agreed project scope, architecture outline, acceptance criteria, and phased delivery roadmap

  2. Knowledge Audit & Data Readiness

    Review representative documents, knowledge repositories, and business systems to identify what should support retrieval. Assess extraction quality, conflicting versions, duplicate content, and missing information. Document source ownership, permissions, update frequency, and deletion requirements. Build an initial set of user questions and reference evidence with your reviewers to guide development and testing.

    Deliverable: Source inventory, data readiness findings, permission requirements, and baseline evaluation questions

  3. Document Ingestion & Indexing

    Configure document parsing, OCR where needed, and chunking that preserves useful section context. Attach source references, version details, and access metadata before generating embeddings and building the search index. Validate extraction and retrieval on sample content, then implement scheduled or event-driven updates, duplicate handling, and deletion processing according to the agreed source requirements.

    Deliverable: Validated ingestion pipeline, searchable index, and documented synchronization and failure-handling procedures

  4. Retrieval & Application Development

    Compare keyword, vector, and hybrid retrieval against the baseline questions, adding reranking where testing supports it. Connect selected evidence to the language model and build the chat or search interface with citations, clarification prompts, and insufficient-evidence responses. Integrate authentication and permission filtering, with scoped API queries where answers require live records or exact calculations.

    Deliverable: Integrated RAG application in a test environment with retrieval configuration, source references, and user review controls

  5. RAG Evaluation & Release Review

    Evaluate retrieval relevance and coverage separately from answer support and citation correctness. Test missing answers, conflicting sources, unauthorized requests, and instructions embedded in retrieved content. Measure response latency and request cost under representative usage. Review findings with the designated stakeholders, resolve release blockers, and document known limitations against the agreed acceptance criteria.

    Deliverable: Evaluation report, regression test suite, documented limitations, and release decision

  6. Deployment & Operational Handoff

    Deploy the approved application to the agreed environment with monitoring for ingestion health, errors, latency, and usage costs. Configure diagnostic access and retention settings, document rollback procedures, and assign responsibility for content and system maintenance. Establish a review process for user feedback and repeat evaluation before releasing material changes to models, prompts, or retrieval settings.

    Deliverable: Production deployment, monitoring configuration, operating runbooks, and maintenance ownership

Enterprise RAG Security
& AI Governance

Protect business knowledge across document ingestion, retrieval, model requests, and application access. Our enterprise RAG development approach covers permission-aware search, data privacy, prompt injection testing, and audit controls, with requirements defined around your users, source systems, and deployment environment.

Identity & Permission-Aware Retrieval

Connect enterprise authentication with retrieval permissions so the application searches only the knowledge each user is authorized to access. Define document, record, and tenant boundaries before retrieved passages reach the language model.

Implementation scope may include

  • Single sign-on integration
  • Role-based access controls
  • Document-level permissions
  • Tenant isolation
  • Scoped service accounts
  • Access-boundary testing

Preserve source-system access boundaries as teams search shared enterprise knowledge.

Data Privacy & Model Handling

Map how documents, retrieved passages, prompts, and responses move through your RAG application. Assess hosting, model providers, encryption, and retention settings against the sensitivity of your information and your data handling requirements.

Implementation scope may include

  • Encryption in transit and at rest
  • Model provider data-flow review
  • Sensitive data minimization
  • Secrets and key management
  • Retention configuration
  • Data residency assessment

Document where business information is processed, stored, retained, and shared.

Secure Ingestion & Knowledge Updates

Define which sources can enter the retrieval pipeline and retain metadata that connects indexed content to its origin. Account for document revisions, access changes, and deletions across source connectors, vector indexes, and relevant caches.

Implementation scope may include

  • Approved source connections
  • Ingestion validation
  • Source provenance and metadata
  • Permission synchronization
  • Index deletion workflows
  • Content update monitoring

Reduce exposure to unapproved, outdated, or revoked content as source systems change.

Prompt Injection & Application Protection

Treat user input and retrieved documents as untrusted content. Test attempts to override instructions, expose confidential information, or trigger unauthorized actions. Enforce tool permissions and business authorization in application code rather than relying on model instructions alone.

Implementation scope may include

  • Prompt injection testing
  • Retrieved content boundaries
  • Input and output validation
  • Scoped API and tool access
  • Rate and resource limits
  • Sensitive-action approvals

Limit what malicious content or unexpected model behavior can access or change.

Security Testing & Audit Monitoring

Test access boundaries before release and monitor the deployed application for failures and suspicious activity. Define useful audit events while limiting sensitive information in prompts, responses, retrieval traces, and operational logs.

Implementation scope may include

  • Cross-tenant access testing
  • Unauthorized query test cases
  • Sensitive log redaction
  • Security event monitoring
  • Audit access and retention
  • Incident response runbooks

Support investigation with relevant evidence, clear ownership, and documented response procedures.

AI Governance & Human Oversight

Document the application's intended use, review requirements, and change approval process. Work with security and compliance stakeholders to translate applicable policies into implementation tasks, test cases, and review evidence.

Implementation scope may include

  • Use and access policies
  • Human review and escalation
  • Model change reviews
  • Documented risk assessments
  • Vendor and deployment reviews
  • Control ownership and handoff

Keep accountability clear as models, knowledge sources, permissions, and requirements evolve.

Security Guidance & Review Deliverables

Define RAG security controls around your data, user permissions, integrations, and hosting requirements. Use established guidance to structure threat assessments, application testing, and AI governance reviews.

Evidence for your technical review

Depending on the agreed scope, deliverables may include data-flow diagrams, an access-control matrix, security test findings, and operational runbooks.

RAG Development Cost
& Investment Planning

Plan your RAG development budget around the application you need to deliver. Content preparation, retrieval complexity, integrations, security, and hosting all influence cost. Separate implementation effort from ongoing model, infrastructure, and maintenance expenses to understand the full investment.

What determines your project cost

Content & Data Preparation

The effort required to prepare enterprise knowledge depends on its condition and structure. Scanned PDFs, complex tables, duplicate files, and inconsistent metadata can require additional processing before retrieval is useful.

  • Document formats and extraction quality
  • OCR, tables, and layout requirements
  • Content volume and update frequency

Search & Answer Requirements

A focused document assistant has a different scope from a multilingual RAG application that combines sources. Retrieval tuning, reranking, citations, and evaluation requirements influence development effort.

  • Question complexity and source coverage
  • Hybrid search and reranking needs
  • Answer quality and response-time targets

Source & Application Integrations

Each connection adds work around authentication, data mapping, synchronization, and error handling. Existing APIs and reliable source metadata can simplify integration; custom connectors require more development.

  • Number and readiness of source APIs
  • Permission and content synchronization
  • Embedded interfaces and live data queries

Security & Access Boundaries

Document permissions, tenant separation, sensitive information, and deployment policies shape the architecture. Include implementation and validation effort for these controls when planning the project budget.

  • Document and tenant access controls
  • Data handling and retention requirements
  • Security testing and review evidence

Hosting & Usage

Operating cost depends on actual usage, retrieved context size, model selection, and infrastructure. Private networking, availability requirements, and peak request volumes can change the deployment budget.

  • Requests, context size, and model usage
  • Embedding, storage, and search resources
  • Hosting, availability, and recovery needs

Evaluation & Ongoing Support

A production RAG system needs review as documents, models, and application behavior change. Budget for regression testing, ingestion monitoring, issue resolution, and the responsibilities retained by your team.

  • Test coverage and human review effort
  • Monitoring and content maintenance
  • Support scope and release frequency

Why Choose THE TISA
for RAG Development

Choosing a RAG development company means evaluating how the team scopes your application, tests retrieval quality, and prepares it for operation. Our approach connects technical decisions to your business workflow, with reviewable evidence, documented tradeoffs, and clear delivery responsibilities.

  • A Defined Problem Before a Build

    We start with the questions your users need answered, the sources available, and the workflow the application should support. This establishes where RAG fits and which requirements need a different technical approach.

    What you can review

    A focused scope with source boundaries, user workflows, and acceptance criteria.

  • Retrieval Tested on Your Content

    Document formats, terminology, and source quality influence retrieval. We use representative content to assess parsing, chunking, search, and evidence selection before expanding the knowledge collection.

    What you can review

    Sample questions and retrieval findings that inform implementation choices.

  • Quality You Can Inspect

    We evaluate retrieval and generated answers separately. Reviews include source support, citation usefulness, missing evidence, and access-sensitive questions so a fluent response is not mistaken for a correct one.

    What you can review

    Agreed evaluation cases, documented findings, and release acceptance checks.

  • Architecture With Clear Tradeoffs

    We compare models, search infrastructure, and deployment options against your requirements. Recommendations account for response time, data handling, maintenance, and operating cost rather than a fixed technology bundle.

    What you can review

    An architecture recommendation with assumptions, dependencies, and alternatives.

  • Built Around Your Existing Systems

    We plan source connections, identity integration, and application interfaces around the systems your teams use. Content updates, permission changes, and integration failures are part of the implementation scope.

    What you can review

    Defined integration boundaries, synchronization behavior, and error handling.

  • Clear Ownership After Launch

    We define how the application will be monitored, updated, and maintained. Handoff covers configuration, operating procedures, and responsibilities, with ongoing support specified according to the agreed engagement.

    What you can review

    Technical documentation, operational runbooks, and an agreed support scope.

Know what the engagement includes

A proposal should make the delivery scope and your team’s responsibilities easy to assess. Confirm these details before implementation begins.

  • Scope, assumptions, and exclusions documented
  • Acceptance criteria agreed before release
  • Architecture and cost tradeoffs explained
  • Deployment and maintenance ownership defined

RAG Development
Questions, Answered

Explore common questions about RAG development costs, implementation timelines, knowledge sources, and deployment options. Learn how retrieval-augmented generation supports source-backed answers, how it differs from fine-tuning, and what to consider for data privacy, evaluation, and ongoing maintenance.

Retrieval-augmented generation (RAG) combines search with a language model. Before generating an answer, the application retrieves relevant content from selected sources, such as policies, manuals, or support articles. A chatbot is an interface and can itself use RAG. The main distinction is whether responses use retrieved business information or rely primarily on the model's existing knowledge. See how this fits AI application development and our RAG services.

RAG development cost depends on source readiness, document processing, retrieval complexity, integrations, access controls, and deployment requirements. A focused knowledge assistant requires a different scope from a multilingual application spanning several business systems. Budget separately for implementation and ongoing model usage, search infrastructure, hosting, evaluation, and maintenance. Review the cost drivers, then get in touch for a tailored estimate after we review your requirements and representative content.

The timeline depends on the agreed scope, source access, content quality, integrations, and acceptance criteria. A focused pilot can validate retrieval and answer quality before a broader production rollout. Custom connectors, complex documents, permission synchronization, and security reviews add work. Our RAG development process establishes proposed milestones, dependencies, and delivery schedule during discovery.

Yes. An internal RAG assistant can help employees find policies, onboarding instructions, product documentation, and troubleshooting guidance. It can provide supporting passages and source references so users can review the evidence. Retrieval should enforce each user's access permissions, and the application should explain when the available sources cannot support an answer. Related builds include AI agent development and AI workflow automation.

RAG applications can retrieve information from PDFs, manuals, internal wikis, shared storage, and selected business records. Connections may include SharePoint, Confluence, Notion, Google Drive, CRM platforms, and databases, depending on API access and permissions. Explore how we connect business knowledge. Broader system work is covered under AI integration services and software development.

No. RAG can reduce unsupported responses by supplying relevant evidence, but retrieval can miss information and a model can misinterpret the passages it receives. Source quality, retrieval testing, citation checks, and insufficient-evidence responses help manage these risks. Important decisions may still require human review, particularly when sources are incomplete, outdated, or conflicting. That grounding pattern is also used in generative AI development. See how we evaluate outcomes.

RAG is useful when answers need information from external sources that must remain searchable, traceable, or regularly updated. Fine-tuning adjusts a model's behavior for tasks such as formatting, terminology, or specialized response patterns. The approaches can be combined. The choice should follow evaluation of your task, available data, quality requirements, and maintenance budget. Compare options with generative AI development and discuss scope via get in touch.

There is no single best model for every RAG application. Candidates can include GPT, Claude, Gemini, Llama, Mistral, and other models suited to the deployment. Compare them using representative questions and retrieved passages, including missing-answer cases. Assess answer support, instruction following, context capacity, language coverage, response time, data handling, and cost. See how we select a RAG technology stack.

Using RAG does not itself require training a foundation model on your documents. However, retrieved passages may be sent to the selected model provider during answer generation. Training use, retention, logging, and processing location depend on the service, configuration, and contractual terms. These settings should be reviewed before connecting confidential information; private hosting also requires appropriate infrastructure and operational controls. Read our privacy policy and security pages.

A RAG application should enforce document, record, and tenant permissions before content reaches the model. Protection also involves authentication, scoped credentials, encryption, sensitive-data handling, and controlled logging. Permission changes and deletions need to propagate to indexes and relevant caches. Review our RAG security practices and the broader controls on security.

Yes, with suitable language models, embeddings, and search configuration. An application can retrieve and answer in the same language or support cross-language retrieval where required. Quality should be tested separately for each supported language, including specialist terminology, source coverage, citations, and responses to questions the documents cannot answer. Get in touch to scope a multilingual knowledge assistant, or browse industry RAG solutions.

Evaluation checks retrieval relevance, answer support, citation accuracy, and handling of questions without sufficient evidence. Operational monitoring covers ingestion failures, application errors, latency, and usage cost. Maintenance includes source updates, permission synchronization, and regression testing when models or retrieval settings change. Review responsibilities and ongoing support are defined in the agreed project scope. See business outcomes, why teams choose THE TISA, and case studies.
