Promo codes
TikTok Shop promo code: how sellers should check the margin before running one
A promo code can make an offer easier to click. It can also quietly remove the margin that was supposed to pay for fees, creators, shipping support, returns, and ads.
Promo code checks for sellers
| Check | What to ask | Why it matters |
|---|---|---|
| Discount amount | Is it a fixed amount or percent off? | Percent codes grow more expensive as price rises. |
| Stacking | Can it combine with coupon, shipping, or creator offers? | Stacked promos can erase margin fast. |
| Creator cut | Does the creator still get paid after the code? | Commission and discount hit the same order. |
| Return reserve | Does the discount attract refund-prone buyers? | Returns still cost money after the sale. |
| Break-even ROAS | How much ad spend can the discounted order afford? | A code can lower the ad room. |
When a promo code makes sense
| Situation | Maybe use it | Skip it when |
|---|---|---|
| First product test | You need a small conversion nudge. | The product only works with a deep discount. |
| Creator campaign | The code is easy to say in content. | Commission plus code leaves no margin. |
| Repeat buyer push | Quality is stable and returns are low. | You still do not know unit economics. |
| Slow inventory | You want to learn price sensitivity. | The item has weak demand and high return risk. |
Use the calculator before spending
Promo margin = price - promo code - fees - cost - commission - ads - returns
