Firstly, let us briefly look at the differences between OpEx vs Capex. OpEx, short for operating expenses, are regular expenses that end up in the expense section of the income statement and are items needed for the day-to-day operation, for example, stationery supplies, cleaning services, or even training.
On the other hand, Capex represents major purchases that have multi-year life spans and if desired, can be resold and such transactions would appear in the balance sheet as company assets. Examples of Capex would be a new truck or new building which get depreciated over their lifespans.
Purchasing a capital asset item is typically a much larger purchase and the project could be multi-phased like the building of a new mine or factory and hence the need for Capex software to manage this type of expenditure.
Now, there is a certain type of OpEx that falls outside the realm of normal operations. These are aptly named Non-Routing Operating expenses. Most companies have an approval process to deal with regular day-to-day OpEx requests but when they are faced with the approval of large Non-Routine Operating Expenses, their process often fails. An example would be approving funds to pay for the settlement of a lawsuit or to approve a large write-down. In both cases, no asset is been purchased but you want to be sure you have the correct approval on the form regardless. For such situations, it is possible to use CapEx software to obtain such approvals for auditing purposes.
