Case Study Overview

The customer challenge, Camptra solution, and business result

The client faced a mandatory migration from Vertex to OPTE with 100,000 employees. Their Payroll Activity Reports exceeded 1GB, causing standard spreadsheet tools to crash. After months of manual effort, they still could not validate migration results or identify the source of payroll variances.

The challenge

The solution

Implementation of Camptra’s Recon Toolset, a cloud-based reconciliation engine. The solution enabled high-volume processing of nearly one million payroll records and utilized AI-powered variance analysis to automatically correlate payroll differences with tax configuration data.

The result

The organization achieved in one day what had previously taken months. They successfully reconciled 100,000 employee records, identified critical wage basis rule changes, and prepared automated employee communications for tax variances.

Inside the Case Study

This case study examines how a major enterprise overcame technical paralysis during a mandatory Oracle Payroll migration. By moving from manual Excel-based processes to a cloud-scale reconciliation engine, the organization successfully validated data for 100,000 employees.

Key highlights include the transition from 1GB+ report failures to sub-24-hour reconciliation results, ensuring accuracy across complex tax engine logic.
