Who are the key stakeholders in an OOH campaign workflow, including approvals, trafficking, and billing?

Short answer

OOH campaigns involve advertisers, media agencies, creative agencies, OOH networks, media owners, and finance teams. Advertisers approve strategy and budgets, agencies plan and traffic, media owners hold final creative authority, and finance teams reconcile billing across the supply chain.

Core stakeholders and their roles

An OOH campaign brings together several distinct parties, each accountable for a different phase of the campaign lifecycle.

Advertiser or brand defines campaign goals, sets budgets, approves the media plan and creative content, and gives final sign-off before launch.

Media agency or OOH specialist develops the media plan, negotiates placements, validates creative specifications, issues trafficking instructions to networks and media owners, and manages billing between the supply chain and the advertiser.

Creative agency or production partner builds the campaign assets, ensures messaging accuracy and legal compliance, and delivers specification-compliant files to the media agency and networks.

OOH networks or platforms aggregate inventory across multiple media owners, manage centralized booking and scheduling, may pre-screen creatives against policy requirements, and can issue consolidated invoices that reduce manual billing overhead.

Media owners or publishers control the physical or digital inventory, such as billboard companies and transit authorities. They upload and schedule approved assets, enforce technical compliance, and invoice agencies or networks for placements.

Finance and billing teams sit across all parties. They match bookings to performance data, audit rate cards, process payments, and resolve discrepancies.

Technology and automation platforms support planning, trafficking logic, and financial reconciliation, reducing manual work while leaving strategic decisions with human stakeholders.

How approvals work across the workflow

Approvals touch three distinct areas: the media plan, creative assets, and compliance checks.

For the media plan, the media agency or OOH specialist drafts locations, formats, timing, and budgets. The advertiser reviews and approves, confirming alignment with audience and budget objectives.

For creative assets, the creative agency leads development with the brand, then hands files to the media agency for specification review. Media owners hold final approval authority before any creative goes live, enforcing technical, policy, and regulatory requirements. This authority is especially significant in digital OOH, where dynamic creative introduces additional pre-approval needs.

Automation platforms can route creatives through approval workflows and generate plan drafts, but agency experts, brand representatives, and media owners retain decision-making authority over what actually runs.

Trafficking: getting approved creative to the right screens

Trafficking covers the operational steps between approval and live display.

Media owners or publishers upload creative files into their content management or player software and schedule them according to approved flight dates, rotation rules, and targeting parameters. Media agencies issue trafficking instructions specifying where, when, and how frequently each creative should run. OOH networks simplify this by aggregating multiple owners' inventory into unified systems, reducing the coordination burden on agencies.

Technical specification compliance is a shared responsibility. Creative agencies produce files in required formats, such as JPG, PNG, MP4, or HTML5, at specified resolutions. Media agencies validate those files against each media owner's requirements. Media owners reject non-conforming files and request corrections before deployment.

In programmatic digital OOH, platforms automate booking across multiple owners and enable dynamic targeting by time of day or location triggers. Despite this automation, media owners still approve creatives before they go live, and buy-side teams monitor pacing and performance.

Traditional OOH relies more heavily on manual negotiation, email, and spreadsheets, with longer planning cycles. Programmatic OOH compresses those cycles through aggregated platforms and integrated analytics, though the fundamental stakeholder responsibilities remain the same.

Billing and financial reconciliation

Billing in OOH reflects the complexity of its supply chain. Media owners invoice media agencies or OOH networks for placements. Agencies then invoice the advertiser for media spend plus agency fees. OOH networks can consolidate invoices from multiple owners into a single document, reducing the administrative burden on agencies and advertisers.

Finance teams across all parties match booking records to performance data, such as impression counts or proof-of-play reports, resolve discrepancies, audit rate cards, and manage makegoods when delivery falls short. Historically this has relied on spreadsheets and manual reconciliation. Automation platforms increasingly handle booking, invoicing, and reconciliation steps, improving accuracy and cutting turnaround time.

Creative agencies bill separately for production services, so advertisers typically manage two parallel billing streams: one for media and one for creative.

How AdQuick handles OOH campaign workflows

Managing multiple stakeholders across approvals, trafficking, and billing is one of the most operationally demanding parts of running a campaign. AdQuick's platform for out of home advertising centralizes media planning, inventory booking, and reporting in one place, reducing the back-and-forth between agencies, networks, and media owners. Buyers can manage creative submissions and trafficking instructions alongside budget tracking, which compresses reconciliation time and gives all parties a shared view of campaign delivery without relying on disconnected spreadsheets or email chains.
