How I Stacked It
Every finance stack tells a story. How I Stacked It looks inside the tools, workflows and decisions real finance leaders use to build better, more scalable finance teams.
Andy Colalillo
RSGx is a $500M+ infrastructure services business operating across 13 legal entities, delivering engineering, construction, maintenance and advisory services across transport infrastructure, oil and gas, resources and minerals, defence, renewables, transmission and distribution, and water in Australia.
As CFO, Andy leads a core finance team of thirteen, and rather than relying on a traditional ERP, the team has built a best-of-breed SaaS finance stack to support a fast-growing, project-based business.

Xero for Core Finance
Xero is the backbone of our finance function. We recently upgraded to Xero Ultra, which builds on the platform already managing the general ledger, AP, AR and bank feeds across all 13 entities.

ApprovalMax for Financial Controls
ApprovalMax gives us structured purchase approval workflows on top of Xero for all business overhead-related spend, helping maintain strong financial controls as the business grows.

Mayday for Month End
Mayday has become a key part of our multi-entity close process, handling consolidations, intercompany reconciliations and month-end automation across the group. Easy Month End is an incredible tool for tracking and ensuring our month-end processes are adhered to, with no steps missed and responsibilities clear.

Employment Hero for HR and Payroll
Employment Hero supports employee records, onboarding, leave management and payroll processing and compliance, while integrating payroll journals with Xero.

Spotlight for Reporting Packs
Spotlight helps us produce our consolidated management reporting and board packs from our Xero data.

AssetAccountant for Fixed Assets
AssetAccountant is our newest addition, giving us a dedicated solution for our fixed asset register and depreciation beyond the core accounting system.

dataSights & Power BI for Reporting
dataSights brings together data from Xero, Procore, BQE Core and other systems into a central data platform, with Power BI delivering month-end tools as well as business line, group executive and board-level reporting dashboards. It also has out-of-the-box consolidated financial reports, like Xero, for the finance team.

Procore for Project Management
Procore provides project financial information including budgets and progress claims, giving Finance greater visibility into project performance and forecasting.

BQE Core for Project Financials
BQE Core manages time, billing and project financials for our consulting engineering businesses.

OpsCentral for Integrations
OpsCentral is our in-house integration platform, connecting our best-of-breed systems where standard integrations don't exist.

Claude for AI
Claude is connected to dataSights, allowing us to use AI to assist with financial reporting, analysis and the month-end process via a direct connection to all our data, both financial and other. Permissions are managed within dataSights and are tightly controlled.
