Client Overview

OSI Packaging (dba Old South Industries) is a 15-person packaging supply distributor serving customers across the American South with shrink wrap, packing tape, packaging equipment, and field service. They are a relationship-driven business where consistent service and deep product knowledge fueled significant growth, including a major surge during COVID that put their old systems to the test.

That growth was impressive, but it exposed a hard truth: the system they had run on for 20 years, a DOS-based platform that was the company’s very first computer system, could not keep pace. OSI Packaging needed a modern ERP built for distribution, and they needed a partner who could help a small, tightly staffed team make the jump without losing what they had built.

Services Involved

The Challenge

OSI Packaging had been running on the same DOS-based system since the company first moved to computers. For years, the team made it work. They built habits around it, kept physical inventory books, and compensated for the gaps with manual effort. But when growth accelerated, those workarounds became unmanageable.

Key challenges included:

The DOS platform was so outdated that accounting software could not interface with it, forcing accounting to maintain a parallel shell in QuickBooks and manually print, scan, and email documents that the system could not send digitally
The system could not accurately reflect true costs, leaving their CPA and leadership flying blind each month with financial reports that simply did not add up
With roughly half of OSI Packaging’s business in drop shipments, team members had to type out the full item description from scratch on every single order, every single time
Consignment location management was done by hand, creating a slow, error-prone process that consumed hours of staff time each week
Staff had to be on-site to work, leaving operations fully exposed to weather disruptions and after-hours emergencies with no flexibility

Our Approach

Conveyance Solutions worked closely with the OSI Packaging team to implement Epicor Prophet 21 in a way that respected their existing processes while building the structure they needed to grow. The goal was not to flip everything overnight. It was to give a 15-person team a system they could trust and actually use from day one.

Conveyance Solutions paired a careful implementation with hands-on training and a post-go-live support model that the OSI Packaging team did not expect but quickly came to rely on.

Removing Manual Work with Process Automation
Converted OSI Packaging’s high-volume drop ship catalog into structured P21 items with proper drop ship disposition, eliminating manual description entry and building a growing order history directly in the system.
PORG Training and Adoption
Trained the OSI Packaging team on P21’s Purchase Order Requirements Generation (PORG) functionality, giving buyers an accurate, filtered requirements list so they could meet customer demand without over-purchasing.
Post-Go-Live Hypercare Support
A dedicated Microsoft Teams channel, staffed with Conveyance Solutions’ P21 experts, gave OSI Packaging a direct line to real answers in real time as new questions arose during live operations.
Consignment Tracking Configuration
Configured P21 to give the team full visibility into what was at each consignment location at any given time, replacing the physical tracking process entirely.
Rapid Customization on the Fly
When drivers began returning the wrong paperwork after delivery, Conveyance Solutions quickly customized document formatting in P21 with color-coded indicators (green to go, red to stay) the team could immediately sort what came back from what should not.

Results & Impact

Within the first weeks of going live on P21, OSI Packaging saw immediate improvements in speed, accuracy, and visibility that would have been impossible on their old DOS system.

60% Faster Workflows
Consignment reconciliation cut from 4 hours to 90 minutes, with that time expected to decrease further as the team grows more familiar with the system.
Faster Processing
Drop ship order entry is quicker across the board, with items pre-configured in P21, so staff no longer have to type out descriptions from scratch each time.
A Single Source of Truth
For the first time, stakeholders have a clear, trustworthy view of true costs and profitability each month.
Increased Order Accuracy
Color-coded document formatting means drivers return the right paperwork every time, reducing rework and delays for the accounting team.
Smarter Purchasing
PORG adoption gave the buying team a structured requirements list that filters out noise and ensures they are ordering what customers actually need.
Real-Time Operational Visibility
Physical inventory books and file cabinet lookups are replaced with live data accessible from anywhere in P21.

With deep Prophet 21 knowledge and a team that stayed present long after go-live, Conveyance Solutions gave OSI Packaging the foundation to keep up with their growth, without leaving anyone behind.
