I like to think most people want to be good. They want to pay their bills on time. Some don't. According to Atradius's 2024 Payment Practices Barometer, 50% of all U.S. B2B invoices are currently overdue.¹ Which got me thinking: what would happen to human behavior if karma worked the same way as invoicing?
Imagine: you cut someone off in traffic on March 6th. A PDF arrives in your cosmic inbox. Payment due: April 5th. You know something's coming. You just don't know what. This is interesting not just because it would make karma legible, but because legibility changes behavior in ways that pure mystery doesn't.
Behavioral economists call this consequence salience — the degree to which a future outcome feels real enough to influence a present decision.² Right now, karma is maximally vague. It might arrive in ten minutes or ten years or never. Net-30 karma would be neither instant nor deferrable. It would sit on the books.
Why This Matters
Timing would become strategy. Finance invented the concept of "float" — the value extracted from the gap between obligation and payment. A net-30 karma system would create moral float. Do something genuinely good on the 29th, and maybe it offsets what's pending. Ethical behavior, suddenly, has an accounts-payable logic.
The deterrence research gets complicated. Studies on criminal sentencing consistently show that certainty of consequence matters more than severity.³ A guaranteed karmic invoice, even a modest one, might outperform the current system of infinite deferral. Late fees, presumably, would accrue.
Dispute resolution would be a nightmare. Anyone who's ever argued over an invoice knows that the moment a debt becomes concrete, it becomes contestable. Was that "small kindness" billable? Was that slight intentional or accidental? The universe has been wisely avoiding this conversation.
The cruelest version of this system isn't the punishment. It's the 30-day window of knowing something's coming and not being able to remember what you did.
There's a reason most moral frameworks keep the ledger hidden. Instant karma short-circuits reflection. Infinite-horizon karma produces paralysis or indifference. Net-30 might be the only interval that generates genuine suspense. Enough time to wonder, not enough time to forget.
