Chapter 01

Job costing fell 2.5 months behind

When Rhea's HR director and accounting manager left within weeks of each other, job costing fell 2.5 months behind with a hard December 31 tax deadline coming.

Each bi-weekly payroll took 4–8 hours of manual work across Paychex, Excel and QuickBooks, following a six-page procedure. A decade earlier Intuit had quoted $30,000 (over $41,000 today) for custom software to fix it. That was out of reach for a firm Rhea's size.

President Marcy Johnson chose not to backfill the role: “If we can use AI to help us not require so much support, that's what I want.”

What AuraPath built with Claude

AuraPath ran four weeks of discovery with Marcy and her team, then built a custom job costing application with Claude Code.

From Paychex reports to a QuickBooks-ready file

The app takes the Paychex reports, calculates salary-adjusted rates and overtime allocation, reconciles everything before it reaches QuickBooks, and outputs a QuickBooks-ready file.

The upload step: QuickBooks weeks 1 and 2, with optional Paychex reconciliation
Step 2, upload. The Paychex file drives reconciliation before anything reaches QuickBooks.

Each payroll, step by step

Paychex reports in

The app starts from the Paychex payroll reports.

Rates and overtime

It calculates salary-adjusted rates and overtime allocation.

Reconciled first

Everything is reconciled before it reaches QuickBooks. On its first runs, this step flagged several historical payroll discrepancies.

QuickBooks-ready out

The app outputs a QuickBooks-ready file.

Chapter 04

An ongoing partnership on Claude Team

Rhea then moved to an ongoing partnership. Its team works in Claude Team with weekly hands-on Claude training from AuraPath, so the firm builds its own AI capability instead of depending on any one person.

In production

Claude Team, trained weekly

Rhea's team has worked in Claude Team with weekly hands-on training from AuraPath since July 2026.

RFP requirements extraction

A Claude skill that extracts requirements from RFPs has been in production since August 2026.

Chapter 05

Each payroll done in about 30 minutes

The 2.5-month backlog was cleared and the December 31 deadline met, and the process no longer depends on one employee.

“We went from dreading job costing—we were 2.5 months behind with a hard deadline—to having each payroll done in 30 minutes. Honestly, I felt like AuraPath undercharged us for the value they delivered. I'm recommending them to everyone I know.”
