Narration
Anna: Measuring consumption isn't one size fits all, and real prices vary wildly.
Greg: Take messaging, card payments, or API platforms: the current rates vary, but the pricing unit is the point.
Anna: AWS S3 charges roughly $0.023 per gigabyte stored, while Lambda bills for compute milliseconds.
Greg: Actually, some teams still count active users because finance loves predictable headcounts.
Anna: Sure, but if you're running an API, billing per million calls—say $1 per 10k—mirrors cost.
Greg: For a student building a side project, paying pennies per call beats negotiating seat licences.
Anna: Different metrics suit different businesses; storage favours volume, collaboration apps track seats.
Greg: And if metrics misalign with value, invoices feel like Sudoku puzzles nobody asked for.
Anna: So choose measures customers recognise, then publish them clearly to avoid debates about mystery fees.
Greg: Transparent metrics turn billing from a tense email thread into a predictable line item.
