Settlement Profit Reconciler — Coupang Wing

The settlement report tells you what Coupang paid you. It does not tell you what you earned, because it does not know what your goods cost. This adds that one missing column, on the settlement page you are already looking at. Enter or import your cost per option ID once. Every settlement row you open is then joined against it and turned into profit per SKU: sale amount, commission, discount, shipping, payout, cost of goods, ad spend, net profit and margin. Return deductions are netted across settlement cycles. Coupang does not reverse a sale in the cycle it happened in — the deduction lands as a negative row weeks later, which is what makes single-cycle math show a profit that never existed. Read more than one cycle and returns are matched back to the original order, so cost of goods is charged on net quantity, not gross. Nothing is guessed. A SKU with no cost entered is reported as missing instead of being counted as free. A return whose original sale has not been read yet is flagged with its amount so you know to open the earlier cycle. Ad spend is not part of the settlement report at all, so until you type it in, the headline is labelled profit excluding ad spend. This version covers Coupang marketplace settlement only. Rocket Growth (RFM) settlement uses different pages and a different schema and is not supported yet — the panel says so rather than showing wrong numbers. Permissions, plainly: no cookie access, no browsing history, no request interception, no account, no sign-in. The extension makes no network request of any kind — not to us, not to Coupang. Your costs never leave your computer. How to use 1. Open the marketplace settlement report in Coupang Wing. 2. Click 정산 순이익 at the bottom right. 3. Import your cost CSV, or type a unit cost for the SKUs listed as missing. 4. Change the search period and page through — every cycle you view is added. 5. Export profit by SKU or the order-level detail as CSV. Features • Profit per SKU from the settlement report joined with your own cost table. • Return and exchange deductions netted across settlement cycles by order number. • Cost table import and export as CSV, so your costs survive a reinstall. • VAT toggles: cash basis or supply-price basis, and cost entered VAT-inclusive or exclusive. The basis is stamped into every export. • Manual ad spend, split across SKUs by revenue share. • Optional net profit column drawn directly into the Wing settlement table. • Columns are located by header label, so a reordered settlement table does not silently produce wrong numbers. • CSV opens correctly in Korean Excel, and an Excel-mangled option ID column is detected on import. Privacy Runs entirely in your browser. It reads the settlement page you have open, stores your cost table and the rows you have viewed in local extension storage on this computer, and writes a CSV to your Downloads when you ask. It requests no cookie, history or web-request permission, and it sends nothing anywhere. Figures are for your own reference and are not a substitute for tax filing or the official settlement statement. Independent extension, not affiliated with Coupang.
