What Is QC and Why It Matters
Quality control — QC for short — is the process of inspecting a product before it ships to you. In the context of the Litbuy Spreadsheet, QC means reviewing the photos your supplier sends after they receive the item from the factory. These photos are your only chance to catch flaws before the package leaves the warehouse. Once it ships, your options narrow significantly.
In 2026, the buyer community has become more sophisticated about QC. The best buyers do not just glance at the photos. They compare them against retail reference images, zoom in on specific details, and ask for retakes when the lighting or angle is wrong. A thorough QC review takes five to ten minutes, but it can save you weeks of disappointment and the hassle of a dispute.
The Litbuy Spreadsheet community maintains a growing library of reference photos for popular batches. Before you place your first order, spend time browsing these references. Know what the retail version looks like from every angle. This knowledge is your most powerful tool when the QC photos arrive.
Understanding QC Photos: What to Ask For
Not all QC photos are created equal. Some suppliers send quick snapshots under fluorescent warehouse lighting. Others provide detailed shots from multiple angles with natural light. The difference matters because poor lighting can hide flaws that become obvious in person.
When you contact your supplier, be explicit about what you need. Ask for photos of the front, back, sides, interior tags, and any specific detail you are concerned about. For shoes, request shots of the toe box, heel, midsole, and insole. For hoodies, ask for the embroidery, drawstrings, hem, and interior fleece. The more specific you are, the more useful the photos will be.
Lighting is critical. Ask for natural light or daylight-balanced shots if possible. Warm warehouse lighting can shift colors by several shades, making a grey hoodie look beige or a navy jacket look black. If the color looks off in the photo, ask for a retake in better light or with a white balance card in the frame.
Angle matters too. A straight-on shot is essential for checking alignment. A top-down shot shows symmetry. A close-up reveals texture and stitching. If your supplier only sends one or two angles, ask for more. The small extra effort on their part saves both of you from problems later.
Category-Specific QC Checkpoints
Every category has its own set of critical details. Here is what to focus on for the most popular categories on the Litbuy Spreadsheet in 2026.
Shoes
The shoe category is the most QC-intensive. Start with the overall shape. The toe box should have the right height and curve. The heel counter should be firm and properly shaped. The midsole paint lines should be clean and consistent. For leather sneakers, the grain pattern should be visible and natural. For mesh runners, the weave pattern should be tight and uniform.
Check the insole. The print should be sharp and correctly placed. Remove the insole if possible and inspect the stitching underneath. The tongue tag should be straight and the font should match retail. The smell test is underrated — a strong chemical odor often indicates cheap glue or synthetic materials that will not age well.
Hoodies and Sweaters
For hoodies, the first thing to check is the weight. The supplier should confirm the GSM, but you can also judge by the drape in the photo. A heavyweight hoodie hangs with structure. The embroidery should have clean edges with no loose threads. The drawstrings should have metal aglets, not plastic. The cuffs and hem should show tight ribbing with good recovery.
Interior fleece is a common QC failure point. The fleece should be consistent in color and texture. Pilling or uneven fleece density is a red flag. The kangaroo pocket should be aligned and the stitching should be straight. For printed hoodies, the print should be centered and the ink should look saturated, not faded.
T-Shirts
T-shirts are simpler but still have critical details. The collar rib should be at least 2cm wide and the stitching should be dense. The shoulder seam should be straight and the sleeve should fall at the right angle. For printed tees, the print alignment should be checked against a reference. The ink should sit on top of the fabric, not soak into it unevenly.
For vintage-wash tees, the distressing should look natural. Perfectly symmetrical distressing is a sign of machine processing rather than authentic garment washing. The color should be slightly uneven in a way that looks intentional, not blotchy.
Jackets and Outerwear
Jackets are high-value items, so QC is especially important. Check the zipper brand and smoothness. YKK is the standard, but some premium reps use Riri or Lampo. The hardware should feel weighty in the photo — if it looks thin or cheap, it probably is. For puffers, the down distribution should look even. There should be no flat spots where the baffles are underfilled.
For waterproof shells, the seam taping should be visible and consistent. The interior lining should be cleanly attached with no loose threads. The hood should be properly shaped and the drawstrings should be functional. Leather jackets require checking the hide texture and the stitching per inch — higher SPI means better construction.
Red Flags That Should Stop You
Some QC issues are fixable. Others are deal-breakers. Here are the red flags that should make you request a replacement or walk away entirely.
First, major alignment errors. If the embroidery is off-center, the print is crooked, or the logo is tilted, the item is unlikely to meet your expectations. These are not minor flaws — they are visible from across the room.
Second, color mismatch. If the color looks significantly different from the retail reference even under the same lighting conditions, the dye batch was wrong. This is especially common with navy, olive, and grey tones where slight shifts are noticeable.
Third, material substitution. If the item is supposed to be cotton fleece but the photo shows polyester sheen, the factory used a cheaper substitute. This changes the feel and durability of the item completely.
Fourth, missing details. If the item is supposed to have specific hardware, tags, or interior features and they are absent, the factory cut corners. Even if the exterior looks okay, the missing details reduce the value and accuracy of the piece.
What to Do If Your QC Fails
If you spot a problem in the QC photos, the first step is to communicate clearly with your supplier. Send a side-by-side comparison showing the flaw and the retail reference. Be polite but specific. Good suppliers want happy customers and will usually offer a replacement or a refund.
If the supplier refuses to address the issue, you have a decision to make. If the flaw is minor and you still want the item, you can proceed but should adjust your expectations. If the flaw is major, ask for a refund or a swap. If you paid with buyer protection, you have recourse if the supplier does not cooperate.
In 2026, the most successful buyers are those who do not rush the QC process. Take your time, compare carefully, and trust your instincts. If something looks wrong, it probably is. The best batch is the one that passes your personal QC standard, not just the one with the lowest price.
FAQ
How many QC photos should I request?
Request at least six photos for simple items and ten or more for complex items like shoes and jackets. The angles should cover every detail you care about.
Can I ask for a video instead of photos?
Some suppliers offer short video clips. Videos are excellent for checking 3D shape and movement. Ask if video QC is available when you place your order.
What if the supplier refuses to retake photos?
If a supplier refuses reasonable retake requests, consider it a red flag about their service quality. Professional suppliers accommodate serious buyers. If they will not, you may want to choose a different supplier.
Should I GL everything from a trusted batch?
Even trusted batches can have occasional duds. Factory QC is not perfect. Always review your photos, even if the batch has a great reputation. A two-minute review is worth the peace of mind.
