    Modernizing a Fragmented Information System with a Unified ERP: From Legacy and Silos to Standardization and Efficiency
    CITADL SASU, Antoine Courouble

    🏢 Client Profile

    A mid-sized company operating in B2B services, with multiple departments relying on disconnected tools to manage critical business operations. The company was facing challenges due to fragmented processes and a legacy, in-house ERP system.


    ⚙️ Initial Situation

    Before the ERP revamp, the client's information system was composed of several isolated tools and platforms:

    • Sales & Finance: managed through a custom-built, in-house ERP application that had become difficult to maintain and evolve.
    • Purchasing & Inventory: handled via an outdated Odoo Community instance, lacking key modern features and integrations.
    • Electronic Signatures: managed using DocuSign, with no connection to other tools.
    • Project Management: operated in JIRA, leading to poor visibility for non-technical stakeholders.
    • Support & Helpdesk: based on a homemade ticketing system, with no standard workflows or reporting capabilities.

    This patchwork of systems created critical issues:

    • Redundant data entries and inconsistency between departments
    • Difficult and costly integrations
    • Maintenance overhead
    • Limited visibility and collaboration between teams
    • Lack of agility and innovation due to technological obsolescence

    🎯 Project Objectives

    • Replace fragmented tools with a single, integrated ERP platform
    • Improve collaboration across departments (sales, support, finance, logistics…)
    • Reduce software licensing and integration costs
    • Offer the company a standard solution with future-proof capabilities

    🚀 Implemented Solution

    The entire scope of the client’s business processes was centralized in Odoo, covering:

    ModuleScope
    SalesCRM, quotations, client contracts
    FinanceInvoicing, accounting, payment follow-ups
    Purchases & InventoryProcurement automation, vendor tracking, stock control
    Project ManagementTask planning, timesheets, resource allocation
    HelpdeskSLA-based ticket management, client portal, KPIs
    Document & Electronic SignaturesUsing Odoo Sign to replace DocuSign

    Key improvements:
    • Full replacement of the homemade ERP and ticketing system
    • Decommissioning of JIRA and DocuSign, cutting unnecessary costs
    • Centralization of data and seamless inter-module communication
    • Adoption of an ERP standard in the market with continuous improvements from the publisher (Odoo)

    ✅ Results & Benefits

    Impact AreaOutcome
    Process Efficiency+30% in operational speed thanks to automated workflows and shared data
    Cost OptimizationSavings on license fees (JIRA, DocuSign) and infrastructure maintenance
    Team CollaborationImproved coordination between sales, support, logistics and finance teams
    Future ScalabilityA modern ERP with updates, new features, and vendor support

    💡 Key Takeaway

    This ERP transformation demonstrates how replacing a fragmented and legacy system with a unified, modern ERP like Odoo can unlock operational efficiency, reduce costs, and future-proof a company’s digital foundation — even without naming the client, the results speak for themselves.
