The flash sales model is one of the most powerful channels for premium brands to move overstock, and one of the most operationally demanding forms of e-commerce to run.
With Garnet, you get both the technology and the team to operate flash sales at scale.
Flash sales and private sales marketplaces operate on fundamentally different dynamics than standard e-commerce. Campaigns are ephemeral: a brand goes live for 48 or 72 hours, stock sells out, and the next brand takes its place. Every operational failure during that window is visible and costly.
This means vendor onboarding must happen in hours, not weeks. Product catalogs of tens of thousands of SKUs must sync in real time. Inventory must be locked the instant a customer adds to cart, or you risk overselling premium stock that cannot be replenished.
Garnet was designed with exactly this pressure in mind. Backed by experience running 200+ marketplace businesses and a founding team that contributed to a marketplace valued at over $500M, we built the infrastructure flash sales operators actually need, not a generic marketplace tool stretched to fit.
Flash sales operators cannot afford a two-week onboarding process for every brand. Garnet's Seller App connects directly with a brand's existing store, whatever platform they use.
Native integrations are available for Shopify, PrestaShop, WooCommerce, and Magento. For brands with no integration-compatible platform, a CSV upload fallback is available so no brand is ever blocked from participating in a campaign.
At peak campaign traffic, inventory moves in seconds. Garnet maintains a bidirectional real-time sync between the brand's source system and your marketplace: stock levels flow in continuously, and orders flow back out immediately upon placement.
There are no nightly batch feeds, no stale inventory counts, and no window for overselling. Product sync and order sync are handled automatically, keeping every SKU accurate across both systems at all times.
Flash sales often involve significant markdown from retail price. How that discount is accounted for between the marketplace and the brand can directly affect vendor relationships, margin calculations, and financial reporting.
Garnet supports all three common models: pre-discount (commission calculated on the original retail price), post-discount (commission calculated on the actual sale price), and neutral (zero-value order sync for brands managing their own accounting). Each vendor can be configured independently to match your contractual terms.
Flash sales brands ship from different locations, use different carriers, and offer different delivery commitments. Garnet lets you configure shipping rules at the vendor level, so each brand operates within its own logistics context without affecting others.
Options include flat shipping rates, live carrier rates, and combined rate rules when a customer orders from multiple vendors in a single transaction. The right cost is calculated automatically at checkout.
Flash sales require precise margin control at every level. Garnet gives you vendor-level discount management, allowing you to set campaign-specific pricing rules per brand without affecting your global catalog.
Commission structures are fully configurable: set a global commission rate as a baseline, override it per vendor, and optionally base commissions on cost price rather than sale price. Discount rules can be applied at the campaign level, the vendor level, or the product level, giving you full control over margin across every campaign.

Got questions about running flash sales marketplaces with Garnet? We've got answers.
Ask a QuestionOnboarding a new brand typically takes minutes, not days. As soon as a brand installs the Garnet Seller App on their Shopify, WooCommerce, PrestaShop, or Magento store, their product catalog and inventory begin syncing automatically. Brands without a compatible platform can upload a CSV file to go live immediately. There is no development work required on the brand's side.
Garnet maintains a bidirectional real-time sync between each brand's source system and your marketplace. Inventory levels are updated continuously throughout a campaign, and orders are written back to the brand's system the moment a purchase is confirmed. This eliminates the lag that causes overselling in batch-based solutions. There are no nightly feeds and no stale stock counts.
Yes. Garnet supports commission configuration at multiple levels. You can set a global default rate that applies across all vendors, then override it for specific vendors or campaigns. Commissions can be calculated as a percentage of the sale price or based on the cost price, depending on your contractual model with each brand.
Shipping rules are configured at the vendor level in Garnet. Each brand can have its own flat rates, live carrier rates, or delivery zone rules, completely independent from other vendors on the platform. When a customer orders from multiple brands in one transaction, Garnet applies the correct shipping logic per vendor and combines costs at checkout automatically.
No. Garnet imposes no hard limit on the number of vendors or SKUs on your marketplace. The platform is built to handle large catalogs and high vendor counts, which is a core requirement for operating flash sales marketplaces with rotating brand campaigns.
Once a campaign closes, Garnet automatically calculates the amounts owed to each brand based on confirmed orders, applied commissions, and any discounts. Payouts can be processed through Stripe, PayPal, Mollie, or bank transfer, on a schedule you define, such as a fixed number of days after campaign close or upon order fulfillment confirmation.
Flash sales typically operate on a no-returns policy, and that is fully supported. However, if your platform allows returns or handles exceptions, Garnet's refund and order management tools are available. Refund flows can be configured per vendor and triggered manually by marketplace admins or automatically based on defined conditions.
Yes. Each brand has access to their own vendor dashboard, where they can view sales, order status, and performance data scoped exclusively to their campaigns. Marketplace admins retain full visibility across all vendors. The level of data shared with each brand is configurable, so you control what each vendor can see.
