>>>Liquidity.
That really depends on how you budget, but for many things I have been involved in these are well known costs that can not simply be postponed really, while it may have some impact on Liquidity, if budgeted for property it would not no matter if it was lump sum or spread out. The effect on a 5 year picture is the same
>>Flexiblity
This is 100% false, SaaS Opex Spend is FAR FAR FAR less flexible than CAPEX spend in the IT Space, take for example Office 365 Vs ONPrem, with OnPrem I can forgo a Capital expense to upgrade some servers, EOL a SAN disk array a year later, or choose to stick on Office 2016 for another year if needed.
Office 365 you pay that bill or your services shut down. That is why company like AutoDesk has removed the ability to buy perpetual Licensing under a CapEx model and have moved to Subscription OpEx model, before if you wanted to Stay on the Previous version of Autocad sure you might take a security risk but the software still worked. Now you do not pay your annual licensing fee well your software no longer works
So no this new OpEx model is in no way more flexible, it more akin to ransomware, pay us or we lock you out
>>>Opportunity costs.
i will agree with opportunity costs. Still from a highly logical and engineering focus more than a Finance focus I will still look at $100k over 5 years or 20K annual to be the same...
