roi.zone generates a retail-specific model for erp: the inputs that matter in this industry, the revenue drivers and the mechanism behind each one, the risks worth naming, and an implementation timeline. Enter your own figures and it builds the case around them.
The output is an executive business case with five-year projections, conservative, moderate and aggressive scenarios, sensitivity analysis, a written assumptions ledger, and prepared answers to the objections a finance reviewer raises. Free, no account.
Return on investment on erp is the net annual gain divided by the total annual cost, as a percentage. The gain combines the value of time your team stops losing and the additional revenue the system enables; the cost combines licences, implementation and ongoing support. roi.zone models the retail-specific drivers behind each of those, then projects them across five years.
Payback depends on your own figures rather than an industry average, which is why roi.zone asks for them. It reports the month cumulative gain overtakes cumulative cost, and shows the same figure under conservative, moderate and aggressive assumptions so you can see how sensitive it is.
A retail erp business case should include the total cost of ownership, the quantified benefits with the mechanism behind each, five-year projections, three scenarios, sensitivity analysis on the drivers that matter most, an explicit assumptions list, a risk register with mitigations, and an implementation timeline.
