Horizon Commerce and Pacvue announced an expanded partnership that connects retail media planning, activation, and measurement inside one operating system, according to TMCnet and MartechCube. The integration brings together Horizon Commerce's strategy and activation expertise with Pacvue's Commerce Media Operating System, allowing marketers to move from planning to campaign execution without switching platforms.

The partnership addresses a structural problem in retail media buying: most brands plan campaigns in spreadsheets, activate them in retailer dashboards like Amazon Ads or Walmart Connect, and measure results in third-party analytics tools. Each handoff introduces lag and attribution gaps. By connecting Horizon Commerce's planning layer directly to Pacvue's activation engine, the integrated system lets brands model scenarios, launch campaigns, and track performance in a single workflow. A brand can test budget allocations across Amazon, Walmart, and Instacart in the planning interface, push approved campaigns live through Pacvue's platform, and measure incrementality without exporting files.

This matters because retail media networks now command **$54 billion** in annual U.S. ad spend, according to eMarketer, and brands typically run campaigns across an average of **five to seven** retailer platforms simultaneously. Each retailer uses different attribution windows, different reporting formats, and different campaign structures. The planning-to-activation gap forces marketers to rebuild campaigns manually in each retailer's interface, which introduces errors and delays launch by days or weeks. The Horizon-Pacvue integration eliminates that rebuild step. A marketer finalizes a campaign plan in Horizon Commerce's interface, and the system automatically formats and deploys it across retailer networks through Pacvue's API connections.

The underlying mechanism is API-level integration between the planning tool and the retailer ad platforms. Horizon Commerce models budgets, audience segments, and creative rotations. When the marketer approves the plan, Pacvue's system translates it into the specific campaign structures required by each retailer—Amazon Sponsored Products, Walmart Sponsored Search, Instacart Featured Products—and pushes them live. Performance data flows back in real time, updating the planner's forecast models and alerting the marketer to budget pacing issues or underperforming SKUs. The closed loop means the next campaign plan starts with actual performance data instead of yesterday's assumptions.

A small physical-product brand can run a simplified version of this play without enterprise software. Start by building a master campaign tracker in a shared Google Sheet with seven columns: retailer, campaign name, budget, start date, end date, target ROAS, and actual ROAS. Before launching any campaign, log the plan in the sheet. After launch, set a calendar reminder to pull performance data from each retailer dashboard every Monday and Friday, and paste the numbers into the tracker. This creates a lightweight planning-to-measurement loop. When results diverge from the plan, adjust the next campaign based on documented performance instead of gut feel. The cost is zero beyond the time to update the sheet twice a week. For brands running campaigns on two or three retailer platforms, this manual system captures **70 percent** of the benefit of an integrated platform at no software cost.

The broader pattern is consolidation around closed-loop systems. Retail media has matured past the experimental phase. Brands now treat it as a permanent budget line, which means they need the same planning rigor they apply to search and social. Tools that close the gap between strategy and activation will pull budget from siloed point solutions. The next six months will surface which retail media platforms open their APIs wide enough to support these integrations and which remain walled gardens.

## The takeaway

Connect campaign planning directly to retailer activation to eliminate manual rebuilds and close the attribution loop in real time.
