Case Study: Media Planning and Buying Agency achieves 30% higher campaign effectiveness and 40% reduction in invoice processing effort with HCL

HCL Enables Business Transformation Through Modernizing For Media Planning And Buying Agency

The customer, a media planning and buying agency, faced an inflexible 30-year-old third‑party media solution and largely manual spreadsheet-driven processes that caused booking errors, lost revenue and poor workflow agility. The agency engaged HCL to deliver a bespoke, future‑proof media planning, buying and integrated billing platform on a demanding 15‑month timeline.

HCL built a custom media planning, buying and integrated billing solution using distributed agile delivery, automating about 80% of planning and buying tasks and integrating with finance for consolidated BI. The new HCL platform delivered measurable impact: 40% reduction in invoice processing effort within seven months, ~30% higher campaign effectiveness and a 5–7% revenue uplift in seven months, sales efficiency up to 1.5x, and more than 30% lower total cost of ownership while removing dependency on the old third‑party system.
