Let’s say it costs less than $20 to acquire a customer(it should) and most times can just be measured as a fraction of fixed operating costs since there is no official advertising expense? Is this really possible? Yes,yes and yes!!!
Even if we broke down all your fixed costs, which are hopefully almost ” to the bone” and put some slight variables in you are hopefully at a very, very manageable daily cost.
Is being hired by one new household per day unreasonable? NO NO NO. If it is, time to change business.
