Case Study: Denny’s achieves 99% billing accuracy and faster finance operations with Workday Adaptive Planning

America’s diner enjoys 99% billing accuracy with Workday Financial Management

Denny’s, America’s Diner, is a 60‑year‑old hospitality brand with more than 1,600 locations and about 3,000 employees. Facing a need to modernize finance and HR systems to support business agility and a vigorous refranchising program, the company launched a phased digital transformation to replace legacy processes and improve reporting, billing, and controls.

By deploying Workday enterprise cloud applications and a restructured data model, Denny’s automated accounting entries, implemented dynamic franchise billing, and enabled real‑time project tracking. The changes delivered measurable gains: billing accuracy rose to 99% (from 95%), manual journal entries fell 50%, AP questions dropped 40%, franchisee invoicing time shortened by four days, SOX control automation improved 135%, and Denny’s achieved about $60K in annual cost reduction.
