Goal is to reduce the OpEx by 50%.
OpEx--> (1) Fixed Costs (2) Variable costs
1) Fixed Cost--> IT infrastructure--> Where is it hosted? on premise? Cloud? If on premise, any cost decrese if hosted on cloud?
2) Variable Cost--> (2a) Salaries (2b) 3rd party transaction costs (2c) Advertisements
(2a) Salaries--> Automate some of the tasks and cut some of the redudencies?--> How much to invest to automate some of the tasks? what is the $$ benfit? Check if this option is feasible.
(2b) 3rd party transaction costs: Leverage the market leader position and negotiate with the 3rd party (such as Visa, Amex, banks etc.,) to reduce the transaction costs.
(2c) Advertisements-->How much is the spend? What is the elasticity? (% decrease in Revenue for % decrease in spend in advertisements). How much of the Revenue are we willing to forgo if we decrease spend in this area.
I would compile each of the benefits ($$) for each of the above areas and see the trade offs/opportunities.
