Core Concepts Enterprise
Starting right: how Core Concepts halved their accounting costs and built a scalable system
Company Background
Core Concepts Enterprise is a licensed general contractor based in Georgia, founded by Trevor J. Lee (CCM, PMP) and Floyd Gabriel Dedeaux II, with over 30 years of combined experience across top-tier general contractors, programme management, and consulting.
The firm specialises in commercial construction with a focus on aviation and public sector work, including projects at Hartsfield-Jackson International Airport.
Having gone full-time in May 2025, Core Concepts is a lean, growth-focused business with a clear roadmap to scale.
The Challenge
When Trevor and Floyd launched Core Concepts, they made a deliberate decision: get the financial workflows right from the start, not after the business had grown past the point where fixing them was easy.
With Procore managing projects and an outsourced CPA handling the books in QuickBooks
Online, every invoice, bill, and commitment claim entered in Procore would otherwise need to be manually communicated to the accountant, who would then re-enter it in QuickBooks. Three steps where one should do.
"You can just see how that scales," says Trevor. "What happens when you're a $20 million business, working with multiple subcontractors, and your project managers are managing the day-to-day? The problem compounds fast without a solution in place."
The Solution
Core Concepts implemented OneCore to connect Procore with QuickBooks Online, with Procore as the single source of truth. Cost codes were mapped to the Chart of Accounts, and financial data flows automatically, with no manual hand over to their CPA or double data entry.
The impact is clearest in their surety reporting obligations. As a bonded public sector contractor, Core Concepts submits quarterly WIP reports, P&L statements, and balance sheets to their surety, and every figure across those three documents must reconcile exactly.
With Procore and QuickBooks in sync, that reconciliation happens naturally rather than depending on error-free manual data entry across two systems.
Nightly error reports flag any exceptions, so issues are caught and resolved before they compound.
The Result
- Halved accounting costs by eliminating duplicate data entry between Procore and QuickBooks
- Saved several hours per week across invoicing, bills, and commitment claims
- Reduced the risk of reconciliation errors across WIP reports, P&L, and balance sheet for quarterly surety submissions
- Established a scalable foundation that can grow with the business
