How many QC photos should I request from my seller?

Request at least 8-12 photos covering all critical angles. Essential shots include: front, back, both sides, top and bottom, close-ups of logos/prints, stitching details, material texture, hardware, and any included accessories or packaging. More photos means fewer surprises when your package arrives.

What should I do if QC photos show defects?

Immediately contact your seller and request a replacement or refund. Most trusted sellers on the oopbuy spreadsheet honor QC-related exchanges within 24-48 hours of photo submission. Be specific about the defect, reference the photo number, and request a replacement with corrected issue. If the seller refuses, escalate through the platform dispute system.

Can I GL (Green Light) or RL (Red Light) an item based on QC?

Yes, the GL/RL system is the standard practice. Green Light (GL) means you approve the item based on QC photos and want it shipped. Red Light (RL) means you reject it and request a replacement or refund. Most experienced oopbuy spreadsheet users GL items with minor acceptable flaws and RL items with significant defects like wrong colors, major stitching errors, or logo misplacements.

How long does QC typically take on oopbuy spreadsheet orders?

QC processing typically takes 2-5 business days from when the seller receives the item from the factory. Premium sellers often complete QC in 24-48 hours. During high-volume periods (before holidays, sales events), expect 5-7 days. Factor this into your overall timeline when planning orders.

Do all oopbuy spreadsheet sellers offer QC photos?

All trusted sellers on the oopbuy spreadsheet offer QC photos as a standard service. However, the quality and quantity of photos varies by seller. Top-tier sellers provide 12+ high-resolution photos with proper lighting and multiple angles. Budget sellers may offer only 4-6 basic photos. Check the Trusted Sellers rankings to identify which sellers provide the best QC service.

The QC Inspection Checklist

Every item category requires specific attention, but the following universal checklist applies to all products on the oopbuy spreadsheet. Use this framework to systematically evaluate each QC photo gallery before making your GL/RL decision.

Universal QC Checklist

Inspection Area	What to Check	Pass Standard	Common Failures
Stitching	Thread consistency, spacing, alignment	Even, straight, no loose threads	Skipped stitches, loose threads, uneven spacing
Materials	Fabric texture, thickness, color match	Matches retail reference closely	Wrong texture, thin material, color off
Logos/Prints	Placement, sizing, color accuracy	Aligned correctly, proper sizing	Crooked, wrong size, faded/wrong color
Hardware	Zippers, buttons, eyelets quality	Smooth function, proper branding	Stiff zippers, loose buttons, no branding
Shape/Structure	Overall silhouette, proportions	Matches authentic silhouette	Bulky, misshapen, wrong proportions
Packaging	Box, tags, tissue, accessories	Clean, complete, matching retail	Damaged box, missing tags, wrong accessories

Understanding GL vs RL Decisions

Green Light (GL) and Red Light (RL) are the binary decisions that drive the QC process. A GL means you accept the item as-is and want it shipped. An RL means you reject it and want a replacement or refund. Understanding the threshold for each decision is critical to avoiding both excessive RLs (which annoy sellers) and accepting poor quality (which disappoints you).

When to GL vs When to RL

Decision framework for confident QC approvals

Green Light (GL) When

Minor stitching variations that are invisible on-foot or at normal viewing distance
Slight color variations that match under normal lighting (not studio flash)
Common batch flaws documented across all units (acceptable for price tier)
Minor packaging imperfections that do not affect the product itself

Red Light (RL) When

Major stitching errors, skipped stitches, or structural failures
Wrong colorway, material, or print that clearly differs from the listing
Crooked, misaligned, or missing logos and branding elements
Incorrect size, shape, or proportions compared to authentic reference

QC by Product Category

Different product categories demand different QC priorities. Shoes require silhouette and material verification, while hoodies need stitching and logo accuracy checks. Our Trusted Sellers ranking identifies which sellers excel at QC for specific categories. Beginners should start with Beginner Spreadsheet Tutorialbefore placing first orders, and budget shoppers should consult the Budget Finds Guidefor realistic QC expectations at lower price points.

QC Process FAQ

QC (Quality Check) is the process of inspecting your purchased items through detailed photos before they are shipped to your address. It is the single most important step in the oopbuy spreadsheet buying process because it allows you to verify quality, catch defects, and request exchanges or refunds before the item leaves the seller. Without QC, you risk receiving a product that does not match expectations, with no recourse for return.
