OnBuy Marketplace Integration

How It Works

One connection. Everything in sync.

Adlixor sits between your systems and your sales channels, keeping data accurate in both directions — automatically.

Connect in minutes

Authorise your OnBuy account in Adlixor with a few clicks. Most connections go live in under five minutes with no developer required.

Sync your data

Adlixor imports your existing products, stock levels, and orders automatically. No spreadsheets, no CSV uploads, no manual mapping.

Manage from one place

From that point on, everything flows automatically. OnBuy stays in sync with every other channel and your ERP around the clock.

Channel Import

  • Publish to any marketplace or eCommerce channel from one hub
  • Go live on a new channel in hours, not weeks
  • Import from multiple channels simultaneously

The Challenge

Managing OnBuy manually alongside your other channels is unsustainable.

OnBuy is a growing UK marketplace with strong buyer demand — but operating it in isolation from your other channels creates inventory gaps, duplicated work, and fragmented order management.

Listing products to OnBuy on top of other channels takes too long

Manually entering product data into OnBuy's seller system — titles, descriptions, categories, images, and variants — on top of your Amazon and eBay operations adds hours of work every time you expand your range. Adlixor publishes from your master catalogue to OnBuy automatically.

Unsynchronised stock leads to oversells and order cancellations

Without a real-time connection between your warehouse and OnBuy, stock levels diverge from your actual availability — especially when other channels are selling at the same time. Adlixor syncs inventory across all channels simultaneously.

OnBuy orders arrive in a separate portal from your other channel orders

Processing OnBuy orders independently of Amazon and eBay orders breaks your fulfilment workflow and makes batch picking and accurate reporting impossible. Adlixor unifies every channel's orders in one queue.

Competitive pricing on OnBuy requires constant manual attention

OnBuy is price-competitive. Without automated pricing rules, you're either losing sales to lower-priced competitors or manually adjusting prices across thousands of SKUs every week. Adlixor applies channel-specific rules automatically.

OnBuy API Integration

Your complete OnBuy workflow, automated.

Adlixor's OnBuy integration handles listing creation, stock management, order processing, and courier dispatch — without requiring manual access to the OnBuy seller portal.

Product & Catalogue Sync

Push product titles, descriptions, images, categories, and variants to OnBuy automatically from your master catalogue. Keep listings updated centrally without touching the OnBuy portal.

Real-Time Stock Management

Live inventory levels sync to OnBuy continuously from your ERP or warehouse. When stock changes on any channel, OnBuy reflects the accurate quantity before the next buyer checks out.

OnBuy-Specific Pricing Rules

Apply OnBuy-specific pricing on top of your base prices. Account for OnBuy's commission structure and maintain competitive positioning without compromising margins across other channels.

Centralised Order Processing

OnBuy orders appear alongside Amazon, eBay, and all other channel orders in Adlixor's unified queue — enabling batch picking, efficient dispatch, and cross-channel reporting.

Courier Label Generation

Generate Royal Mail, DPD, DHL, and Evri labels directly from OnBuy orders within Adlixor. Service selection is automatic based on weight and destination.

Tracking Auto-Confirmed

Tracking numbers post back to OnBuy automatically after dispatch — confirming shipment, keeping buyers informed, and protecting your seller performance metrics.

Category & Variant Mapping

OnBuy's category taxonomy and variant formats map automatically from your product data. Size, colour, and other variations are handled without manual configuration per product.

Unified Performance Reporting

View OnBuy revenue and order data alongside all other channels in Adlixor — without logging into the OnBuy seller portal separately to pull reports.

Capabilities

For UK sellers adding OnBuy to their channel mix.

Adlixor makes OnBuy a zero-overhead addition to your multi-channel operation — connecting it to your existing product data, stock, and fulfilment workflow from day one.

Zero-Overhead Channel Addition

Once your catalogue is in Adlixor, adding OnBuy as a channel is a configuration exercise. Product data, stock, and order management all flow through Adlixor without building new processes for OnBuy specifically.

One Catalogue, Multiple Channels

Your product master in Adlixor feeds OnBuy alongside Amazon, eBay, B&Q, ManoMano, and your eCommerce platforms. Update a product once and every connected channel reflects the change.

OnBuy Pricing Strategy

OnBuy's fee structure differs from Amazon and eBay. Adlixor's pricing rules engine lets you configure OnBuy-specific margins — ensuring profitability on every OnBuy sale without manual price calculations.

Seller Metric Protection

Oversells and late dispatch damage your OnBuy seller status. Adlixor's real-time stock sync and automated tracking confirmation eliminate the manual processes that create these issues.

AI Listing Optimisation

Adlixor's AI Listing Optimisation surfaces improvements to your OnBuy product titles and descriptions — helping your products rank more prominently in OnBuy search and improve conversion.

ERP Integration for Stock & Pricing

If your stock and pricing originate in a GenetiQ or RBA ERP, Adlixor bridges your back office to OnBuy — ensuring product data and live inventory always reflect your actual business position.
