The justification for a fee of $15,000 is saving $24,000 a year. If there's a licence fee of $15,000 then the savings is only $9,000 per year and the first year has a negative cash flow of $6,000 and there is only $3,000 positive cash flow in year two [not accounting for the time value of money].
None of which consider a the legal fees associated with drafting a licencing agreement or the administrative costs of managing such an agreement.
The thing is, you see, that BoB is all about helping other people make money. B2C is more about 've much money have you got?'
