Agentic AI Platform for Sales Enquiries, Quotations and Pasyment Automation

The end client is a Kenya-based retail and manufacturing business serving customers through WhatsApp, Instagram and Facebook.

The organisation required an intelligent sales platform that could reduce manual work across customer enquiries, product discovery, quotations, payments and invoicing while retaining sales-team involvement in complex or high-value transactions.

The end client’s identity is withheld due to contractual confidentiality and NDA obligations.

Project Overview

    1. The project involved the development of a multi-agent AI platform for automating the customer journey from enquiry to payment.

      The solution was designed and developed by a SilwaTech partner company through SilwaTech’s partner delivery ecosystem.

      The platform incorporated specialised AI agents for

      • Customer enquiry capture
      • Requirement analysis
      • Visual product identification
      • Product recommendation
      • Quotation generation
      • Payment handling
      • Billing and invoicing
      • Customer follow-up

      A central orchestrator coordinated the agents and managed handoffs across the sales workflow. Human review and escalation were retained for high-value, complex or sensitive transactions.

Case Study Topics

Business Challenge

  • The sales process involved multiple disconnected channels and manual activities.

    Key challenges included

    • Customer enquiries fragmented across different social platforms
    • Slow response times during busy periods
    • Manual follow-up of prospective customers
    • Inconsistent capture of quantities, preferences, timelines and purchase intent
    • Product recommendations dependent on individual sales experience
    • Spreadsheet-based quotations creating delays and pricing risks
    • Limited visibility of inventory and payment status
    • Manual billing and invoice preparation
    • Difficulty scaling enquiry handling without increasing headcount

    The client needed an integrated sales workflow capable of moving customers from their initial enquiry to a completed purchase while escalating complex cases to the sales team.

Engagement Model

The project was delivered through SilwaTech’s partner ecosystem under a partner-led implementation model.

The solution architecture, agentic AI development, ERP integration, channel integration, application development, testing and technical implementation were performed by an experienced SilwaTech partner company. SilwaTech contributed through engagement alignment, partner collaboration and coordination of the required AI-automation, commerce and enterprise-integration capabilities.

The cross-functional delivery team included specialists in

  • Agentic AI engineering
  • Multi-agent orchestration
  • Backend platform development
  • ERP and inventory integration
  • Social and messaging-channel integration
  • Payment-workflow integration
  • Cloud infrastructure and operations
  • Quality assurance and security testing

Delivery followed an iterative approach across the enquiry-to-payment journey. Individual workflow stages were implemented and validated before being connected through the central orchestration layer.

The identities of the end client and implementation partner remain confidential. SilwaTech does not represent itself as the direct contracting party or sole technical implementer for this engagement.

Security and Governance Focus

The platform handled customer information, commercial pricing, and payment-related workflows, requiring strong controls at every stage.

Key areas of focus included

  • Secure payment-link and QR-code generation
  • Human verification before invoice creation where required
  • Role-based access to sales, pricing and payment information
  • Encryption of communication between channels, agents and the ERP
  • Controlled access to product and inventory data
  • Logging of agent decisions, actions and workflow handoffs
  • Traceable escalation to human sales personnel
  • Confirmation of uncertain visual product matches
  • Exception handling for failed or unusual transactions
  • Human oversight of complex and high-value deals

These controls helped ensure that automated sales activities remained secure, reviewable and accountable.
