| Ordering workflow | A clean workflow reduces wrong variants and delays. | Can you paste product links easily? Are notes clear? Is the cart simple? |
| QC photos | Warehouse images help you reject or exchange flawed items before shipping. | Check photo count, clarity, measurement support, and extra photo cost. |
| Storage | Storage time affects how long you can build a parcel. | Review free storage days, extension rules, and abandoned item policy. |
| Shipping lines | Different countries and item types need different routes. | Compare price, speed, restrictions, insurance, and volumetric calculation. |
| Support | Problems happen with sellers, refunds, returns, and tracking. | Look for clear ticket support, response speed, and dispute handling. |
