10 / HR & BUSINESS VALUE

Product workflows, analytics and operating controls for a B2B business.

BUSINESS WORKFLOWS / ANALYTICS

From brochure site to operating product.

Inquiry lifecycle: New → Viewed → In Progress → Proposal Sent → Closed / Rejected, with search, filtering, product association, notes, status history, first-view tracking and mail retry status.
First-party analytics measures page views, product impressions and clicks, inquiry CTA interactions, form opens and starts, successful submissions and PDF downloads.
The dashboard reports traffic development, product interest, inquiry volume, funnel drop-off, top products, product-to-inquiry conversion, traffic sources, navigation transitions and PDF engagement.
Seven server-enforced roles cover Super Admin, Administrator, Editorial, Products, Inquiries, Analytics and Viewer access.
Privacy design avoids Google Analytics, external tracking pixels, raw IP storage, PHP session persistence and browser fingerprint storage.
