Marketplace management software for multi-vendor stores

Three ways for vendors to create products

Vendors are not all the same. Some prefer to list products manually one by one, others need to upload hundreds at once, and many already have a live store they want to connect. Garnet supports all three paths.

• Manual entry: a Shopify-like interface vendors already know, covering title, description, variants, images, and pricing.
• CSV bulk upload: import hundreds of products at once with automatic field mapping and variant support.
• Platform integrations: connect a Shopify or WooCommerce store and sync products automatically. No copy-pasting.

Whichever method a vendor uses, every product follows the same approval flow before it goes live. Learn more in the documentation.

Data-rich product pages with custom product fields

Standard Shopify fields cover the basics, but many marketplaces need more. A bike marketplace needs frame size and gear count. A food marketplace needs origin, certifications, and allergens. A fashion platform needs material composition and a fit guide.

Garnet's Product fields feature lets you define custom fields (Origin, Category, Material, and more) that vendors fill in when creating a product. These fields are stored as Shopify metafields and can automatically link products to the right collections, powering your navigation and filtering without manual work.

Quality control at scale: your product approval workflow

Keeping product quality consistent across dozens or hundreds of vendors is one of the hardest jobs for any marketplace. Garnet gives you a customizable approval workflow that holds standards high without creating bottlenecks.

• Define listing guidelines (required fields, image standards, description rules) so vendors know what to submit before they submit it.
• One-click approval or rejection per product, with optional notes sent back to the vendor.
• Approved products are automatically linked to collections based on their product fields, removing manual curation.
• Grant trusted status to high-performing vendors so their products auto-approve and go live instantly.

Inventory sync with editorial control

When a vendor connects their external Shopify or WooCommerce store, product data flows in automatically. But raw vendor data often needs adapting for your marketplace: different terminology, a more descriptive title, richer content.

Garnet supports three sync modes, so you choose the right level of control per vendor:

• Full sync: every field (title, description, images, price, stock) stays in sync with the vendor's source store.
• Price and stock sync: your edits to titles and descriptions are preserved while price and inventory stay live.
• Stock-only sync: maximum editorial control; only inventory levels update from the vendor's store.

For example, a vendor's product titled Red Shirt can be published on your marketplace as Seventies Long Sleeve Shirt, Red, and that name is not overwritten by the next sync. Read about product sync settings.
