Case Study: The Unico System - Replacing a Legacy ERP System

Updated: Aug 11, 2023

Learn how Turnkey and Dynamics 365 Finance and Operations helped the client achieve obsolete inventory from 15%-0% and reduced labor 30%.

Technology Used

Microsoft Dynamics 365 Finance and Operations and Supply Chain Management

Business Challenge

The Unico System is the leader in Small Duct High Velocity (SDHV) heating and cooling systems, located in Arnold, MO. Established in 1985, Unico manufactures SDHV systems designed to adapt to old homes, custom homes, and small spaces without compromising comfort, design, or efficiency.

Before Dynamics, Unico was primarily using legacy ERP systems for accounting and manufacturing was reported as an expense. Running on spreadsheets and paper with manual data entry, Unico knew it was time for a change, since their legacy ERP systems wouldn’t work for a company that would eventually own 95% of the small duct HVAC market. They needed a system that could scale with their growing business.


After spending a year on time studies in preparation for Dynamics 365 Finance and Operations, their initial implementation came in 2019. Contracting accounting resources from Turnkey Technologies allowed Unico to have a responsive, helpful partner throughout an involved process.

Taking advantage of the combined offering, Unico also implemented the Supply Chain modules related to warehousing and took the opportunity to make concurrent changes to their warehouse layout, enabling cohesion between finance and operations and their supply chain in manufacturing. Now, they are swiftly moving toward their goal to double inventory turns and seeing the cash flow benefits.


Obsolete Inventory from 15%-0%

Reduced Labor: 30%

Business Benefits:

Benefit 1: Significant Improvement in Cost and Margin Understanding

With Dynamics for Finance and Operations, Unico is able to now track purchases and sales in real-time, informing the manufacturing costs and detailing their profit margins. Automation provides comprehensive financial records with valuable insights into the profitability of each product line and customer segment, making it easier for them to adjust operations to maximize profits.

Benefit 2: Improved Efficiency and Productivity

Instead of using rough forecasts, Dynamics allowed Unico to drive their inventory down by letting the system drive the process. Unico’s use of kit modules and phantom items for flat BOMs allows them to experience reduced lead times, quicker delivery of products to customers, and improved customer satisfaction. By utilizing single-piece flow, Unico is able to reduce costs for their mix and modest product line while increasing efficiency and productivity, rarely experiencing stockouts.

Benefit 3: Improved Inventory Planning

By using Dynamics to successfully transition to standard costing from their previous average costing model, Unico greatly improved accuracy in cost estimates, pricing, and materials budgeting. This improved inventory planning and execution is critical to their continued success.
