Set packaging and price hypotheses for a bootstrapped B2B SaaS and test willingness and ability to pay, keeping recurring revenue, one-off services, pipeline, and cash as separate numbers. Use this when the founder asks "what should we charge," "how do we package this," "are they willing to pay," or when free users are not converting. Do not use it to write the offer or differentiation (founder-positioning), to model full unit economics and runway (founder-economics), or to treat a listed price as proof of demand (founder-validate).
