Best Buy Canada recently hosted a webinar with two of its marketplace experts, Lois (Seller Optimization Manager) and David (Category Manager for Mobile Computing), breaking down the seller journey from launch through long-term growth. The session was refreshingly practical: no hype, just a clear look at what separates sellers who gain traction from those who stall out.

Here are the key takeaways, along with what they mean for brands scaling into retail marketplaces.

The First 30 Days Are About Readiness, Not Revenue

Lois put it plainly: "The first 30 days are like bringing home a new baby. Everyone's excited, but reality sets in fast."

The most common misconception among new sellers? Expecting instant sales the moment listings go live. In reality, the first month is about building a foundation that can support momentum later. Lois outlined three priorities every new seller should focus on:

Competitive pricing. Traffic may already be flowing, but you will not win the sale if your offers are not in line with the market. Monitoring category trends and competitor pricing from day one is essential, and Best Buy's Seller Hub provides the data to do it.

Inventory depth. Momentum stalls quickly when products go out of stock. Sellers who maintain steady availability convert more consistently and signal reliability to both the platform and shoppers.

A clear marketing objective. Whether the goal is visibility, conversion, or a combination, knowing what you are optimizing for determines which tools and tactics to activate early. Best Buy's team can help align sponsored ads and promotions to those goals.

David added a fourth: first impressions on the product detail page. A strong primary image, accurate attributes, and well-written short and long descriptions are what get a shopper to click in the first place.

Unlocking the First Sale: It Is Usually a Conversion Problem, Not a Traffic Problem

When sellers have not made a sale in the first 30 days, the instinct is to assume nobody is seeing their products. More often, the products are getting views; there is just not enough reason for a shopper to buy.

The usual culprits are weak promotions, uncompetitive pricing, and listings that do not build trust. Once those gaps close, the same traffic that was not converting can start turning into sales.

How Do New Marketplace Sellers Build Customer Trust?

Trust was a recurring theme throughout the webinar. Sellers on Best Buy Marketplace already benefit from a "halo effect" by being on a platform customers know and trust. But beyond that, the panel recommended focusing on the end-to-end customer experience: accurate product information, fast shipping, and proactive communication. When customers consistently receive what they expect (or better), positive reviews follow naturally.

David emphasized the communication piece specifically: "Sometimes a quick response to answer a question or resolve an issue is all the difference in building customer loyalty."

Should New Marketplace Sellers Invest in Advertising Early?

The panel's answer was a clear yes. Best Buy's Sponsored Products program is a conversion tool, not just an awareness play. David recommended starting campaigns as early as possible, noting that the algorithm needs at least 90 days to build accurate results. Tabitha, the host, mentioned that sellers have seen return on ad spend as high as 6,000% during peak seasons like Black Friday.

The takeaway: investing early in sponsored products, even at a modest budget, compounds over time.

How Important Is Fulfillment for New Marketplace Sellers?

Extremely. The platform pays close attention to a seller's first few orders. Consistently on-time delivery signals reliability, boosts early metrics, and positions listings higher. A single bad fulfillment experience can damage reviews, cost you the buy box, and erode the trust you are trying to build.

For brands managing fulfillment across multiple retail channels, this is where operational systems and integration infrastructure become critical. Keeping inventory accurate, shipping confirmations timely, and order data flowing cleanly between your systems and the marketplace is not optional at scale; it is the baseline.

Days 30 to 90: Treating Early Results as Data, Not a Finish Line

The sellers who grow past their initial traction share a common trait: they treat early results as data points and keep iterating. Those who plateau tend to stop adjusting right when momentum is building.

What Metrics Should Marketplace Sellers Track?

Lois recommended focusing on metrics tied to customer experience: fulfillment performance, customer service responsiveness, and how negative reviews are handled. These directly drive conversion and repeat purchases. Sellers who let service tickets pile up or react poorly to early reviews stall their own growth.

David highlighted the Premier Seller Status as a goal worth pursuing. It is awarded to sellers who maintain a green scorecard, offer free shipping over $35, provide top-rated customer service, and charge no restocking fees. Earning that badge adds another layer of trust with shoppers.

What Is the Biggest Mistake Sellers Make When Scaling?

Scaling too fast without operational readiness. Sellers who do not anticipate volume, staff properly, or have systems in place to handle demand spikes end up sacrificing product and service quality. The panel recommended doubling down on inventory depth and building operational capacity (labor, systems, processes) before pushing for aggressive growth.

This is particularly relevant for brands expanding into new retail marketplaces. Managing EDI document exchange, purchase orders, invoices, and advance ship notices across multiple channels without reliable automation creates exactly the kind of operational bottleneck that stalls growth.

When Should Sellers Start Running Promotions?

Nothing is ever too early, according to Lois, as long as the promotions align with clear business objectives. Early promotions accelerate visibility and strengthen conversion. David added a practical tip: if a promoted product is performing well, consider extending the promotion an extra week to maintain momentum and push the product higher in search results.

Consistent promotional cadence matters more than occasional large discounts. Regular deals and ads create compounding momentum.

Beyond 90 Days: What Long-Term Success Looks Like

After the first 90 days, sellers transition from Best Buy's onboarding team to a dedicated account manager through a warm handoff meeting. From there, the focus shifts to sustained, scalable growth.

David outlined what the strongest sellers consistently do:

Scale resources to match growth. Whether it is customer support, inventory management, or pricing updates, successful sellers plan staffing and systems around peak periods like holiday and back-to-school.

Maintain promotional cadence. Consistent visibility through regular promotions builds a rhythm that compounds over time.

Communicate with your account manager. Bi-weekly, monthly, or through email, the sellers who keep Best Buy's team in the loop get better strategic recommendations and faster problem resolution.

What Accelerates Growth After the First 90 Days?

David shared several tactics that top-performing sellers use: exclusive offers for Best Buy or edge-to-market pricing (where your Best Buy price beats competitors), continued investment in Sponsored Products (with some sellers seeing 20 to 25x return on ad spend), and participating in Best Buy's marketing events like the Outlet Sale (for non-new and refurbished products) and Deal of the Day.

How Do Strong Sellers Keep Adapting?

Knowing the competition and the market is essential. For non-new sellers, that means understanding who is winning the buy box and why. For private label brands, it means having a clear value proposition and differentiating on the product detail page.

David also encouraged creativity: bundles, free bonus offers, and ideas the seller brings to the table. Best Buy's marketplace team is open to trying new approaches.

The Rapid-Fire Truths Every Seller Should Know

The webinar closed with a rapid-fire segment that distilled the session into sharp, quotable truths:

"If we don't sell in 30 days, the marketplace doesn't work" is false. Traffic may be there, but the offer is not competitive enough yet.

"More SKUs always means more sales" is false. Expanding assortment helps, but only if you have the resources, inventory, pricing, and content to manage a larger catalog.

"The first 90 days determine your long-term success" is mostly true. Strong habits start early, and consistency in the early days pays off in the long run.

"A good product page, in-stock inventory, and the right price beats promotions alone" is true. Promotional pricing is just one piece of the puzzle.

"Fast, reliable fulfillment can make or break you" is true. A single bad experience can impact reviews, cost the buy box, and damage customer trust.

"Successful sellers don't need ongoing support" is absolutely false. Best Buy's close partnership with sellers is one of the platform's key value propositions.

What This Means for Brands Scaling into Retail Marketplaces

The throughline from Best Buy's webinar is clear: marketplace success is not about a single tactic or a lucky product launch. It is about getting the fundamentals right (pricing, inventory, content, fulfillment), staying consistent, iterating on real data, and using the support systems available.

For brands selling across multiple retail channels, many of these fundamentals depend on the operational infrastructure underneath them. Keeping inventory synchronized, processing orders accurately, and exchanging trading partner documents reliably is the work that makes everything else possible. When the back-end runs cleanly, sellers can focus on the growth levers the Best Buy team described: promotions, advertising, content optimization, and customer experience.

Whether you are evaluating Best Buy Marketplace or already live and looking to build momentum, the playbook is the same. Start with readiness, stay engaged, treat early results as learning, and build the systems that let you scale without breaking.
