@lacspace/commission
Commission & payout engine — flat/percent/marginal-tier/progressive-slab rules with caps & floors, composite and per-category rates, tax-on-commission (inclusive/exclusive), explicit rounding modes, and a marketplace split (platform + seller + affiliate) whose lines conserve the gross exactly. Integer minor units, zero floats. Isomorphic.
npm i @lacspace/commissionUsage
import { commission, split } from "@lacspace/commission";
// tiered marketplace take-rate, capped
const fee = commission({ type: "tiered", cap: 100000, tiers: [
{ upTo: 500000, rate: 0.10 },
{ rate: 0.08 },
] }, 800000);
// pay 3 sellers exactly — no paisa created or lost
const shares = split(100000, [{ id: "a", weight: 1 }, { id: "b", weight: 1 }, { id: "c", weight: 1 }]);
// 33334 | 33333 | 33333Exports 2
