Case Study: Rayno Window Film achieves precise roll-based inventory tracking and rapid growth with Finale Inventory

Rayno Window Film - Customer Case Study

Rayno Window Film, founded in 2003, manufactures premium carbon- and ceramic-based window films for automotive and architectural markets. Because they sell full rolls that are cut to custom widths and lengths and must track lot IDs across many product variations, the company outgrew Excel and needed an inventory system that could handle large numbers of SKUs and non‑standard product handling.

Rayno implemented Finale Inventory in 2015 to manage lot tracking, roll variations, transfers, and both standard and manual entries across sales and operations. Finale’s customizable reports helped Rayno analyze sales trends as the business scaled—nearly doubling year over year—and the company also benefited from responsive customer support with timely help when needed.
