mediaSuite
Publishing software from [frevel & fey] for media houses: advertising sales, order management, publication calendars and subscription billing, grown out of their adware advertising system.
It carries a publisher’s whole commercial vocabulary — Objekt, Ausgabe, Erscheinungstermin, Kapazität — which is exactly what a general-purpose CRM has no model for. We migrate that model into HubSpot custom objects, import the history by script, and keep the two in step during the parallel phase.
