As answered by people managing DeveloperToolStack and Margn.shop.
Margn.shop's answer:
Next.js 15 (App Router), React 19, TypeScript, PostgreSQL with TypeORM, Tailwind CSS, and Recharts. Deployed on Railway. Official TikTok Shop Partner API integration via OAuth.
Margn.shop's answer:
Margn is built natively for TikTok Shop — not a Shopify tool adapted to it. It calculates your real net profit after TikTok's referral fees, payment processing, affiliate commissions, ad spend and refunds, per product and per day. It's also the only TikTok Shop profit tracker with a permanent free tier (500 orders/month, no credit card) and an interactive profit calculator on the homepage.
Margn.shop's answer:
Three reasons: price, simplicity, and a real free plan. Most TikTok Shop profit trackers start at $49/month with no free tier — Margn is €19/month for unlimited orders, and free forever up to 500 orders/month. Two plans instead of complex tiered pricing. Mobile-first as an installable PWA, where most alternatives are desktop-only. Setup takes about two minutes: connect via OAuth, import your COGS by CSV, done.
Margn.shop's answer:
Solo TikTok Shop sellers and small brands doing £10K–£100K per month in GMV, mostly in the UK and France. Typically dropshippers or own-brand sellers who make sales but can't tell whether they're actually profitable, because TikTok Seller Centre has no COGS field and reports on settlement dates rather than order dates.
Margn.shop's answer:
TikTok Shop shows sellers their revenue, never their profit. There's no field to enter product costs, and payout data arrives 8 to 31 days after delivery — so sellers scale products that lose money without realising it. Existing tools were either market-intelligence platforms (Kalodata, FastMoss) or Shopify-first trackers retrofitted to TikTok. Margn was built to answer one question properly: what do you actually keep after every cost?
