Data Portal

    The invoicing for digital buys:
    the end of a nightmare.
  • As you may know, the delivery data used for invoicing the digital buys, are the publishers' data.
  • For the same campaign, the discrepancies between Agencies' and Publishers' data vary and create a real nightmare to match the numbers together and close the gaps between campaigns and invoices.
  • Now, imagine a world where Agencies had the Publishers' data, directly in their tools, which allow them to action payments earlier and without having to negotiate and discuss the gaps.

With the ambition to improve the process and workflows of digital media buyings, MBS has developed the Data Portal © MBS and is already in production with one agency and offers multiple ways to capture data in the portal:

  • A REST API allowing publishers to send delivery data, as often and whenever they need.
  • An Excel document upload giving the media owner the choice to import directly and without any additional procedure the delivery data for one or multiple campaigns, all the campaigns for the year, with a simple drag and drop.

Available today with the tool used by Publicis Media (Prisma), the Data Portal © MBS is available for all agencies, no matter the tools they use to manage their digital campaigns.

By the way, we almost forgot: it's free for publishers.
