    The Challenge

    What needed solving

    • Selection process spread across Excel sheets, vendor catalogs, and tribal engineering knowledge — every project required 3–5 days of cross-checking.
    • Quotations regularly missed sub-components or used outdated pricing, leading to margin leaks and post-PO disputes.
    • Audits were painful: no audit trail of which performance numbers were used or when.
    • Sales engineers in 4 regional offices each kept their own version of the calculator — different teams shipped different specs for the same project.

    Our Approach

    How we delivered

    • Replaced spreadsheets with the MileSoft AHU Selection Software as the single source of truth, hosted on the client's intranet.
    • Loaded their full coil, fan (3rd party fan suppliers), and damper libraries; mapped each item to certified performance curves.
    • Layered the Lifecycle Cost Analysis module so engineers could compare equipment options on TCO, not just first cost.
    • Built role-based workflows so sales engineers configure, technical leads approve, and procurement auto-generates BOMs.
