Construction ERP ROI Calculator

This calculator estimates the potential business value of implementing MYOB Acumatica ERP in your construction or project-based business. It models three key outputs: your estimated cumulative net benefit over three years (total savings minus total costs), your ROI percentage, and your estimated payback period — the point at which cumulative savings exceed your total investment. It uses your self-reported inputs across labour, technology spend, and current systems to generate these estimates.

The calculator takes the total monthly hours you report spending on financial admin, project admin, procurement, and rework or data errors, then applies a 60% efficiency rate. This reflects the industry assumption that ERP automation and system integration will eliminate the majority of manual, repetitive effort — but acknowledges that some hours will remain. A secondary multiplier is applied based on your current systems environment: businesses already using some ERP capability will see a lower uplift than those operating primarily on spreadsheets or disconnected tools. A multiplier between 0.50 and 1.00 is applied based on your current technology environment.

A 60% rate is a deliberately conservative assumption. Some businesses achieve higher savings — particularly those migrating from spreadsheets or multiple disconnected systems — while others in more mature technology environments may see a lower uplift. We have chosen 60% to ensure results are realistic and defensible rather than inflated. If you would like a more precise assessment based on your actual workflows, our team can provide a tailored analysis.

The payback period accounts for the fact that licence costs are ongoing — meaning the business is spending money every month while simultaneously generating savings. The formula used is: implementation cost divided by the difference between combined monthly savings and monthly licence costs. This gives the number of months of net savings required to fully recoup the upfront implementation investment.

Implementation costs vary based on the size and complexity of your business, the number of integrations required, data migration needs, and the level of customisation involved. The figure used in this calculator — NZD $70,000 — represents an estimated average for a mid-sized New Zealand business implementing a base configuration of MYOB Acumatica. Your actual cost may be higher or lower. Avanza Solutions will provide a proposal following an initial discovery conversation.

This calculator uses an indicative average of NZD $180 per user per month. Actual licence pricing depends on the number of users and the level of system access each user needs. Some user types — such as limited-access or read-only users — may be available at a lower rate. Avanza Solutions will confirm licence costs as part of a formal proposal.

Yes. MYOB Acumatica includes purpose-built functionality for construction and project-based businesses, including job costing, project accounting, progress billing, subcontractor management, and contract management. It is localised for the New Zealand market with built-in GST compliance, NZ payroll, and local support. Avanza Solutions specialises in MYOB Acumatica implementations for construction, manufacturing, and distribution businesses across New Zealand.

The calculator assumes MYOB Acumatica will replace approximately 70% of your existing monthly software and IT infrastructure spend. This reflects the consolidation of tools such as standalone accounting software, job management platforms, payroll systems, spreadsheet-based reporting, and integration platforms into a single ERP. Some tools may be retained alongside MYOB Acumatica — for example, industry-specific estimating software — which is why a full 100% replacement is not assumed.
