How to Find Best Selling SKUs in Your Shopify Store

Finding your top products isn’t just about what brings in the most money. It’s about knowing what keeps selling, month after month, and why. That’s why Shopify store owners need to find best selling SKU Shopify store data quickly and clearly.

Why Top-Selling SKUs Matter

They Keep Revenue Consistent

If a handful of products bring in most of your sales, you need to protect and promote them. Knowing your best SKUs helps you avoid stockouts, prep for promotions, and plan bundles.

They Help You Cut Waste

When you know what sells best, you can stop wasting time and money pushing slow-moving items. This lets you put your budget where it works.

They Show You What Your Market Actually Wants

Top SKUs give you real feedback. They reveal what your customers keep coming back for, which is especially helpful if you’re trying to improve product-market fit.

How To Spot Winning SKUs In Your Shopify Store

1. Look At Sales Volume Over Time

One-time spikes don’t mean much. Watch what sells consistently over 30, 60, or 90 days. A tool like By the Numbers’ Products Sold by SKU Report makes this faster and more reliable than digging through default Shopify exports.

2. Sort By Units Sold, Not Just Revenue

Sometimes your best sellers aren’t the most expensive items. It’s the ones that move most often. Tracking total units sold helps you find them fast.

3. Look For Repeat Orders

SKUs that keep getting bought are clear winners. Repeat orders also hint at customer loyalty and long-term value, especially when paired with retention metrics.

Common Mistakes To Avoid

Only Looking At Revenue

A product that makes you the most money might be hard to restock, have low margins, or attract high return rates. Don’t assume high-dollar equals high value.

Ignoring Product Variants

Sometimes it’s not the whole product line that’s winning—it’s one size or color that drives all the sales. Use SKU-level tracking to get that level of detail.

Using Data That’s Too Old

Trends shift quickly. If you’re looking at data from six months ago, you may be missing what’s working now. That’s why Shopify stores need to check their SKU data at least monthly.

Using SKU Data To Grow

Stock Smarter

Once you’ve nailed down your winners, stock more of them. Watch inventory closely, especially during peak seasons. You can also test bundles using top-selling SKUs as anchors.

Market With Confidence

Put your ad dollars behind what works. If a product is already a proven seller, it’s easier to turn new visitors into buyers with the right offer.

Build Better Offers

Use high-performing SKUs in your welcome flows, bundles, or loyalty perks. You’re giving new buyers a “safe” first purchase that’s more likely to convert.

The Shortcut Most Stores Miss

You can’t afford to guess which products are your best sellers. But Shopify’s built-in tools make SKU-level analysis hard to get right. That’s why many store owners use By the Numbers to track SKU performance clearly, down to the variant. It gives you the answers fast—without needing to export spreadsheets or hire an analyst.
