How a $65M industrial distributor on Epicor P21 launched a B2B portal in 8 weeks — and reduced CS call volume by 38%.

What's Inside

• Company profile: $65M annual revenue, 1,200 active customer accounts, 45,000-item catalog, Epicor P21 ERP, three branch locations
• Implementation scope: contract pricing integration, B2B account portal with 4-level hierarchy, order visibility with branch inventory, and approval workflows for orders above $5,000
• AI copilot usage: P21 schema analysis generated 87% of field mappings requiring only review; AI copilot produced 340 pricing test scenarios that identified 14 pricing edge cases before go-live
• Implementation timeline breakdown: weeks 1-2 for ERP mapping, weeks 3-5 for configuration and extension development, weeks 6-8 for testing and UAT — total 8 weeks from kickoff to production launch
• Outcomes at 6 months: 38% reduction in CS call volume for order status inquiries; 62% of order volume now placed through portal (up from 0%); customer satisfaction score improved 12 points; $180,000 estimated annual reduction in order entry overhead
• Lessons learned: the account hierarchy configuration required more iteration than the AI copilot initially modeled; pricing edge cases in P21 would have been difficult to catch without AI-generated test coverage
