Korea's Coupang held supplier invoices 233 days. The legal cap was 60.
On 26 February 2026, Korea's Fair Trade Commission (the antitrust regulator, or KFTC) fined Coupang ₩2.185 billion for paying suppliers up to 233 days late — the Large Retail Business Act caps the delay at 60 days. ₩280.9 billion of supplier invoices were held past the cap; ₩853 million of statutory 15.5%-per-year late-interest was never paid. Coupang ran two margin floors on each supplier (PPM and GM) and demanded price cuts, extra ad-spend payments, or a quietly trimmed next purchase order when a supplier missed the target. Suppliers shipped 24,986 free sample units worth ₩536 million into the Coupang sampler programme; when the samples did not sell, Coupang kept the inventory. A follow-up KFTC site inspection opened in January 2026 — a second round of supplier-coercion allegations is still under review.
01The pain
A Korean supplier shipped goods to Coupang's warehouses in spring 2024 and waited 233 days to be paid — well into the next winter. The legal cap is 60 days. It comes from the Large Retail Business Act, a 2012 Korean law that limits how long a big retailer can hold supplier invoices. On 26 February 2026, Korea's Fair Trade Commission (the antitrust regulator, or KFTC) fined Coupang ₩2.185 billion.1 The breach covered ₩280.9 billion of unpaid invoices.2
The pain is concentrated on one side of the platform. Suppliers shipping into Rocket Delivery are classed as B2B vendors, not open-market sellers. Rocket Delivery is Coupang's direct-purchase channel: Coupang buys the goods, holds them in its own warehouses, and ships next-day to shoppers.3 On top of the 60-day breach, KFTC found Coupang never paid the ₩853 million of statutory 15.5%-per-year late-interest the law requires.1 It also ran internal margin floors. Coupang calls them PPM (a per-product profit target) and GM (gross margin). When a supplier missed the floor, Coupang demanded a price cut, an extra ad-spend payment, or a quietly trimmed next purchase order.3
The Coupang sampler programme made it worse. Suppliers shipped 24,986 free sample units worth ₩536 million; when the samples did not sell, Coupang kept the inventory.3 KFTC opened a follow-up site inspection in January 2026 — a second round of supplier-coercion allegations is still under review.4

02Who solves this today
Korean receivables-factoring fintechs, supply-chain-finance platforms, and online-seller pre-settlement services that an SME supplier or marketplace seller reaches for to bridge Coupang's 60-to-233-day payment gap. Each homepage was checked live on the date of writing. Inclusion is not endorsement.
Listed providers publicly self-market in one of the wedges named above. Inclusion is not endorsement. Considered and dropped (each WebFetched on the date of writing): fin2b.com / www.fin2b.com (root and /kr/ both returned ECONNREFUSED across this cycle — could not capture verbatim self-marketing); asklaw.ai.kr (homepage self-marketing this cycle led with employment, lease, divorce, inheritance and tax wedges, not 대규모유통업법 / KFTC complaint help, despite an internal blog post on the topic — wrong-lane on the homepage); sellerhub.co.kr (homepage primarily self-markets multi-mall product management, not the receivables / pre-settlement wedge; the 선정산 wedge runs through partner NICEabc, listed above instead); KODIT / 중소벤처기업진흥공단 매출채권 팩토링 (government agencies, not private vendors); Coupang's own 셀러월렛 fast-settlement (the platform that causes the pain; not a third-party solution); big-firm M&A and antitrust practices at Kim & Chang, Yulchon, Bae Kim & Lee, Lee & Ko, Shin & Kim (each homepage's marketing copy leads with general antitrust and chaebol-defense work rather than supplier-side 대규모유통업법 enforcement).
