Vanguard Infrastructure & Civil Engineering
$220,000 Change Orders Recovered • $48,000/yr License Saved
Vanguard manages commercial civil contracting and infrastructure projects. Disconnection between field site supervisors, project task milestones, subcontractor contracts, and accounting resulted in unbilled change orders and delayed progress payments. By transitioning to Great ERP, Vanguard integrated job costing, retainage accounting, and milestone billing, recovering $220,000 in previously unbilled contract scope.
Vanguard Infrastructure & Civil Engineering (Sydney & Brisbane, Australia) successfully modernized its operations using Great ERP by Greatzern Consulting. Migrating from Procore ($48,000/yr) + Disconnected Xero + Manual Change Orders, the company deployed double-entry accounting and achieved $220,000 Change Orders Recovered • $48,000/yr License Saved with a seamless 5 Business Days deployment.
Operational Comparison: Before vs After Great ERP
Detailed evaluation of workflows prior to and following the Great ERP deployment.

| Progress & Retainage Billing | Manual AIA/G702 style claim generation taking over a week per billing cycle | One-click progress billing with automated retainage withholding calculation |
| Subcontractor Contract Governance | Verbal change orders with delayed vendor invoice disputes | Digital contract milestone sign-offs with photo attachments and approval workflows |
| Software Subscription Cost | Escalating per-project software fees on Procore + Xero user add-ons | Predictable enterprise plan with hands-on setup and zero per-user seat penalties |

ERP Localization for Australia
Pre-configured with AUD multi-currency ledgers, local tax calculation schemas, e-invoicing protocols, and domestic banking integrations.
The Operational Challenge & Solution
Vanguard was losing substantial profit margins through unbilled project change orders. When site engineers agreed to client scope modifications on job sites, the paperwork often failed to reach the finance department until after final project sign-off, making retrospective billing difficult. Concurrently, software subscription costs from specialized construction platforms continued to climb by 15% annually.
Vanguard deployed Great ERP's Projects and Taskly modules pre-integrated with double-entry job costing. Within 5 business days, 24 active construction project budgets, subcontractor retainage balances, and equipment tracking schedules were loaded into the platform. Field site engineers accessed the system directly via mobile browsers without per-user licensing restrictions.
Quantifiable Business Impact
Audited operational and financial returns achieved by Vanguard Infrastructure & Civil Engineering.
$240,000 saved over 5 years by replacing construction SaaS subscriptions with flat lifetime access.
$220,000 in previously unbilled contract variations captured in the first 6 months of operation.
"In civil contracting, profit margins are won or lost on job costing accuracy and change order tracking. Great ERP connected our job site engineers directly with our accounting department. We captured over $220,000 in billable variations in our first six months that previously would have slipped through the cracks."
