@zenuinebit/invoice

Calculate invoice totals and render a print-ready HTML invoice. Zero dependencies; works in Node and the browser.

import { calculateTotals, renderInvoiceHTML } from "@zenuinebit/invoice";

const totals = calculateTotals(invoice);   // { subtotal, discount, tax, total }
const html = renderInvoiceHTML(invoice);   // open it and call window.print(), or feed it to a PDF tool

Money is computed in integer minor units via @zenuinebit/money and @zenuinebit/tax, so totals never drift and respect each currency's decimals (JPY has none). All text is HTML-escaped; only extraHtml is inserted raw, so pass trusted markup only (for example a QR code from @zenuinebit/qrcode).
