Voltra — Self-Hosted Multivendor PHP Marketplace
Launch your own Amazon-style multi-vendor marketplace with a complete, self-hosted PHP solution.
Voltra is built for marketplaces where multiple sellers can manage their own products, receive orders, track earnings and handle their stores from dedicated vendor dashboards — while the marketplace owner gets complete control through a powerful admin panel.
Core Marketplace
• Multi-vendor storefront
• Vendor registration and approval
• Individual seller stores
• Product, variant and SKU management
• Categories, brands, tags and specifications
• Product search with filters
• Wishlist and reviews
• Verified-purchase reviews
• Customer Q&A
• Other-seller price comparison
• Pincode delivery checking
Advanced Multi-Vendor Checkout
A single cart can contain products from multiple sellers.
The system automatically separates the order into vendor-specific packages, with independent:
• Shipping
• ETA
• Fulfillment status
• Tracking information
• Commission calculation
• Vendor earnings
This makes the order structure suitable for a real marketplace rather than a simple multi-seller catalog.
Vendor Dashboard
Each seller gets a dedicated dashboard with:
• Sales overview
• Orders to ship
• Product management
• Variant matrix
• Inventory management
• Returns
• Reviews and Q&A
• Coupons
• Earnings ledger
• Payout history
• Store profile
• Vacation mode
• Sales analytics
• Sponsored-product performance
Powerful Admin Panel
The marketplace owner gets complete control over:
• Dashboard & marketplace statistics
• Products and moderation
• Vendors and approvals
• Orders and refunds
• Returns
• Vendor payouts
• Categories and brands
• Attributes and specifications
• Tags
• Pages and blog posts
• Media library
• Menus and widgets
• Coupons
• Ads & sponsored products
• Analytics
• Subscribers
• Shipping zones
• Users
• REST API tokens
• SMTP configuration
• Payment configuration
• Backup & restore
• Marketplace settings
Commission & Payout System
Voltra uses an append-only vendor ledger instead of relying on a simple mutable wallet balance.
Commission can be configured using:
Vendor override → Category commission → Global default
Vendor earnings remain pending until the order reaches the appropriate delivery state, after which they become available for payout.
Refunds and commissions are also reconciled through the ledger.
Payments
Built-in payment support includes:
• Razorpay
• PayPal Advanced
• PayPal Simple/IPN
• Cash on Delivery
Payment callbacks are verified server-side instead of blindly trusting browser responses.
Order Tracking
Every package maintains an auditable event history.
Vendors and administrators can update:
• Order status
• Carrier
• Tracking number
• Location
• Buyer-visible notes
Customers can view the complete tracking timeline directly from their account.
Sponsored Products & Advertising
The marketplace includes native monetization features.
Vendors can purchase sponsored product placements while administrators can manage advertising slots, date ranges, impressions and clicks.
Sponsored products are clearly marked and kept separate from organic listings.
Built-In Analytics
Track important marketplace activity including:
• Product views
• Add-to-cart events
• Purchases
• Revenue
• Conversion rate
• Top products
• Vendor traffic
• Sponsored-product performance
• Zero-result searches
The zero-result search data can help marketplace owners discover products customers are looking for but cannot currently find.
REST API
An optional REST API module provides:
• Bearer-token authentication
• Read/write scopes
• Token hashing
• Rate limiting
• Request logging
• Vendor-scoped API access
• Bulk stock operations
Vendor API access is restricted to the vendor's own catalog.
SEO Ready
SEO is generated automatically from marketplace content.
The system includes structured data for products, offers, sellers, ratings, stores, organizations, breadcrumbs and blog content.
It also generates:
• sitemap.xml
• robots.txt
• Open Graph metadata
• Automatic product metadata
• Aggregate offers for multi-seller products
Security-Focused Architecture
The application includes:
• PHP password hashing
• Session regeneration
• Login throttling
• CSRF protection
• Prepared SQL statements
• Upload validation
• Randomized upload filenames
• Protected database directory
• Disabled PHP execution inside uploads
• Vendor ownership checks on mutating operations
Vendor permissions are enforced at the query/endpoint level rather than simply hiding admin buttons.
