Costco Online Supplier Strategy: Why Your Product Page Now Matters as Much as Your Pallet

Oct 25

4 min read

Costco online supplier strategy used to be an afterthought for brands focused on warehouse shelves. That is changing. Costco’s e-commerce sales are growing several times faster than its warehouse sales, and the member who finds your product online may be the same one who buys it in person. A brand that treats its Costco.com page as an afterthought is leaving sales and credibility on the table.

Today is October 25, 2026. This guide covers what Costco has reported about its online growth, what we do and do not know about content requirements, and how to prepare.

A note on sources and what we could not find. The growth figures come from a Digital Commerce 360 article on Costco’s fiscal Q2 2026 results (quarter ended February 15, 2026), which cites Costco’s earnings call. We did not find a Costco-published supplier guide for product page content, deadlines, or fees. A Salsify page says brands can publish “below-the-fold” content to Costco from that platform, but it states no requirements, costs, deadlines or launch date. Treat content requirements as a question for your buyer.

What Costco Has Reported

According to Digital Commerce 360:

E-commerce sales rose 22.6% year over year in fiscal Q2 2026, against a 7.4% rise in comparable sales. The article gave no dollar figure.
For the first half of fiscal 2026, e-commerce grew 21.6%.
Website traffic rose 32% and app traffic rose 45%.
Personalized product carousels drove more than $470 million in e-commerce sales.
CFO Gary Millerchip said personalization was “starting to create measurable impacts,” and that Costco has “a clear road map for future digital enhancements” aimed at growing digitally enabled sales faster than overall sales.
CEO Ron Vachris said Costco is working with leading AI companies so its value proposition appears in AI shopping tools.
Same-day delivery through Instacart, Uber Eats and DoorDash is growing faster than overall digital sales.

These are one quarter and one article. Check Costco’s latest earnings release for current numbers.

What It Means for a Supplier

The numbers describe Costco as a whole, not your product. We do not know how many items are online-only, how much of any given item’s sales happen online, or how Costco decides what appears where. What we can say is that Costco is investing in personalization and discovery, which means product data and content are likely to affect whether members find and trust your item. That is an inference, not a Costco statement.

Costco also said it would discontinue Costco Next and move its most popular items into the core Costco app and website, according to our earlier MOJO guide on the shutdown, which cited Costco’s fiscal Q4 2026 earnings call. It did not say which items or when. That suggests the main site is where Costco wants its online assortment to live.

Content: What We Know

The Salsify page describes tools for building enhanced product content such as video, comparison tables and image galleries, plus specs, nutrition information and warranty details. It does not say which suppliers must use them, when, or at what cost, and it invites visitors to sign up for launch updates, so availability is unclear. Ask your Costco contact whether enhanced content is available for your item and what the process is.

Your Costco Online Supplier Strategy Checklist

Ask your buyer how your item will appear online, and whether it is warehouse-only, online-only or both.
Request the content specifications: image sizes, copy limits, attributes, and who submits them.
Build a product data file: dimensions, weight, ingredients, nutrition, claims and UPC.
Shoot clean images: front, back, side, ingredient panel, and one lifestyle shot.
Write benefit-first copy that matches your packaging and avoids unverified claims.
Plan for comparison shopping, since members see your price per unit next to others.
Check inventory for online demand, including shipping and delivery options.
Prepare for reviews and questions, and decide who responds.
Track online sales separately from warehouse sales if Costco shares the data.
Align roadshow and online timing, so a demo spike meets a ready page.

Common Mistakes

Treating the product page as someone else’s job.
Using photos that do not match the packaging.
Making claims online that your label cannot support.
Forgetting that online customers cannot taste a sample.
Not planning inventory for online orders.
Ignoring reviews.

Why This Is a Brand Strategy Issue

Members research before they shop, and your Costco page may be the first place they meet your brand. Strong content supports your roadshows, your coupon book offer and your sales velocity. A consistent story online and in the warehouse is stronger than two separate ones.
