Manufacturing ERP ROI Calculator

This calculator estimates the potential business value of implementing MYOB Acumatica ERP in your manufacturing 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 your team spends on production planning and scheduling, inventory and materials management, procurement, financial administration, quality and compliance, and rework or data errors. It then applies a 60% efficiency rate, reflecting the industry assumption that ERP automation and system integration will eliminate the majority of manual, repetitive effort — but acknowledges that some hours will always remain. A secondary multiplier is then 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 manufacturing businesses achieve higher savings — particularly those migrating from spreadsheets or multiple disconnected systems such as a standalone MRP tool alongside separate accounting software and spreadsheet-based reporting. 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 and production environment, our team can provide a tailored analysis.

The systems multiplier reflects how much efficiency headroom exists in your current setup. A business running entirely on spreadsheets has more to gain from ERP than one already using some integrated tools. The multipliers used in this calculator are as follows: mostly spreadsheets (1.00), accounting software and spreadsheets (0.90), a mix of disconnected tools such as MRP, accounting, and inventory systems (0.95), and some ERP capability already in place (0.50). Note that the mix of disconnected tools option carries a slightly higher multiplier than accounting software only, because managing data across multiple unconnected systems typically creates more duplication, rework, and manual effort than a single accounting platform used alongside spreadsheets.

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. If monthly savings do not exceed monthly licence costs, the calculator will indicate that no payback is achieved within the 3-year period.

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 manufacturing businesses, including production order management, bill of materials, MRP and capacity planning, batch and serial number traceability, quality management, and multi-site inventory control. 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 manufacturing, construction, and distribution businesses across New Zealand, with experience across discrete, job-shop, process, make-to-order, and make-to-stock environments.

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, MRP or production planning systems, inventory management platforms, payroll software, spreadsheet-based reporting, and integration platforms into a single ERP. Some tools may be retained alongside MYOB Acumatica — for example, CAD software, industry-specific estimating tools, or specialist quality management platforms — which is why a full 100% replacement is not assumed.

This calculator is designed to be relevant across a range of manufacturing environments including discrete and job-shop manufacturing, process and batch manufacturing, make-to-order, and make-to-stock operations. The pain points captured — production scheduling, inventory accuracy, procurement lead times, batch traceability, and financial visibility — are common across all of these manufacturing types. However, the specific savings achievable in your business will depend on the nature of your production processes, the complexity of your BOM and routing structures, and the current maturity of your systems.
