Solving the Vertex-to-OPTE Migration Crisis: A Case Study in Enterprise Payroll Reconciliation

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 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.

02

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.

03

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.
