Overview
Buyers search screens by location, audience size, and price, then plan a campaign right on the listing: pick dates, dayparts, and slots, and watch pricing and estimated impressions update instantly. Quotes come straight from the operator.
The platform stays out of the money: no payments, no middleman. What it keeps is the paper trail. Quotations have statuses and expiry dates, offers print as formal documents, campaigns sit on a Gantt-style timeline, and each agreement has a dispute option if the terms don't match what was agreed.
What I built
- Screen directory with city and indoor/outdoor filters, price and relevance sorting, and a map view with estimated daily passers-by.
- Listings with photos, an embedded location map, and specs: screen size, resolution, brightness, loop length, and slot availability.
- Live campaign planner for dates, dayparts (morning, daytime, evening), and slots, with instant pricing and impression estimates.
- Quotations with Accepted / Viewed / Rejected status, expiry dates, and download-or-print offers.
- Gantt-style campaign timeline plus a full agreement record per campaign, including creative requirements and a dispute option.
