QC Tutorial
Master quality control for oopbuy spreadsheet orders
Quality Control (QC) is the most critical step in the oopbuy spreadsheet shopping process. It is your only opportunity to verify your items before they leave the seller and begin the international journey to your door. This comprehensive QC tutorial teaches you exactly how to inspect, evaluate, and approve your orders with confidence.
What is QC and Why Does It Matter?
QC is the process where your seller or agent photographs your items before shipping. These photos let you verify size, color, quality, and accuracy. Without QC, you are essentially buying blind. The best oopbuy spreadsheet sellers include free QC as standard practice.
Step-by-Step QC Process
Follow this workflow every time you order through an oopbuy spreadsheet:
- Step 1: Order your items and select a seller with QC support (check our trusted sellers list)
- Step 2: Wait 2-5 days for seller to receive and photograph your items
- Step 3: Review QC photos carefully against this checklist
- Step 4: Approve or request exchange within the approval window
- Step 5: Authorize shipping once satisfied with QC
QC Inspection Checklist
| Check Item | What to Look For | Common Issues |
|---|---|---|
| Size | Measurements match size chart | 1-2cm discrepancies |
| Color | Matches product photos | Dye batch variations |
| Materials | Fabric weight and feel | Cheaper substitutions |
| Stitching | Clean, even seams | Loose threads, uneven |
| Logos | Placement and accuracy | Crooked or wrong size |
| Hardware | Zippers, buttons, tags | Missing or incorrect |
| Smell | No chemical odors | Strong factory smell |
Red Flags: When to Reject QC
Some QC issues are deal-breakers. Reject your QC if you notice: wrong item entirely, major color difference, significant size error, missing components, strong chemical odor, or visible damage. Most reputable sellers offer one free exchange for QC failures.
QC Pro Tip
Always save your QC photos. If your item arrives damaged or different from QC, these photos are your proof for disputes or refunds. Top buyers maintain a QC archive for every order.
Advanced QC: Using Measurement Tools
For clothing items, advanced QC includes measuring against a ruler in the photo. Most sellers include a measuring tape in QC shots. Compare these measurements to the size chart you ordered from. Allow 1-2cm tolerance for handmade items.
