Maintenance & support

Long-term operation of production systems: updates, extensions, and fixes — for systems that have to run for years.

  1. IT distribution

    99% uptime

    99% uptime

    Challenge
    Resellers asking manufacturers for project prices ran the process manually: every inquiry took time and resources on both sides, and the back-and-forth slowed the whole chain down.
    Approach
    A web application that processes price inquiries automatically. We integrated it into the manufacturer's infrastructure through interfaces to its eCRM and ERP systems, so requests now flow through without manual handling.
    Outcome
    The system has been in production for over ten years. IT resellers in 15 countries use it for their price inquiries every day, with 99% uptime.

    Real-time status

    Real-time status

    Challenge
    Customers submitted marketing support requests by email. Documents were scattered across threads, not available to all parties, approval status stayed unclear — and every step took longer than it should have.
    Approach
    A web portal where customers submit marketing requests directly, with an approval chain on the manufacturer's side. All documents live in one place, customers see the real-time status of their request, and they upload supporting material to the portal themselves.
    Outcome
    The email process was replaced end to end: requests, documents, and approvals now run in one system, with transparency for all parties.

  3. Marketing & CRM

    GDPR-compliant

    GDPR-compliant

    Challenge
    The requirement: fast, GDPR-compliant creation and sending of information by email to precisely selected customer groups.
    Approach
    An application with reusable email templates and customizable content — text, images, links. Distribution lists are built from criteria such as customer industry, sales area, and address; the sender is set centrally or per sales representative, directly through the CRM integration.
    Outcome
    Campaigns go out quickly, to exactly the right recipients, and stay inside the existing CRM structure.
