Five-year TCO, payback and renewal uplift examples with the arithmetic shown, plus a selection process, quote comparison and timeline you can reuse.
An ERP decision is a five-year commitment priced in instalments. These guides turn the cost lines into worked numbers so you can test a shortlist before you sign, and give you a process for collecting quotes that can actually be compared.
The ERP selection checklist is the starting point: requirements, shortlisting, scripted demos, reference checks and contract review in order. From there, work through a 3–5-year total cost of ownership example, test whether the project pays for itself with the payback worked example, and model what a renewal uplift does to years four and five. The quote comparison guide shows how to normalise proposals that are priced differently, the timeline guide sets realistic phases, and the tax guide explains how subscriptions, implementation costs and the instant asset write-off are generally treated.
The calculators use the same formulas as the examples. All figures in examples are illustrative; replace them with your own quotes and staff costs.
