Ecommerce Inventory System: Sync Shopify, Amazon & More
BSimple’s ecommerce inventory system keeps your stock synchronized across all sales channels with automated updates:
- Multi-channel inventory sync for Shopify, Amazon, eBay, and marketplaces
- Real-time stock updates to prevent overselling across channels
- Unified order management from all platforms in one dashboard
- Automatic Xero integration for accurate ecommerce accounting
- Wholesale and B2B alongside ecommerce retail
- Warehouse and fulfillment automation for online orders
Selling online through multiple channels is brilliant for revenue—until your inventory becomes a nightmare. You sell an item on Shopify, but forget to update Amazon. Someone buys the last unit on both platforms simultaneously. Now you’re dealing with an angry customer, a refund, and potential negative reviews.
Ecommerce inventory management is fundamentally about synchronization. Your stock levels need to be accurate across every channel in real-time. When an item sells on any platform, every other platform needs to know immediately. When you receive new stock, all channels need to reflect the updated availability.
BSimple specializes in multi-channel ecommerce inventory for Australian businesses. Whether you’re selling through Shopify and Amazon, managing dropshipping alongside stocked products, or running ecommerce and wholesale B2B from the same inventory, BSimple keeps everything synchronized and accurate.
Multi-Channel Synchronization: One Source of Truth
The fundamental problem with selling across multiple ecommerce platforms is inventory fragmentation. Each platform wants to be the source of truth for your stock data, but you can only have one actual source of truth—your real inventory.
BSimple acts as your centralized inventory management system, pushing accurate stock levels to all connected sales channels. When a sale happens on any platform, BSimple receives the notification, decrements the inventory, and immediately updates all other channels. This happens in real-time, not overnight or in batches.
Key synchronization features:
- Bi-directional sync: Stock updates flow from BSimple to all channels, orders flow from channels back to BSimple
- Oversell prevention: Real-time updates prevent selling items you don’t have
- Buffer stock management: Reserve inventory for wholesale customers while selling excess through marketplaces
- Channel-specific inventory allocation: Dedicate specific quantities to specific channels if needed
This centralized approach means you manage inventory in one place—BSimple—and trust that all your sales channels stay synchronized. No more logging into five different platforms to update stock levels manually.
Shopify, Amazon, and Marketplace Integration
BSimple integrates with major ecommerce platforms and marketplaces that Australian businesses rely on. Shopify stores, Amazon Seller accounts, eBay listings, and other marketplaces all connect to BSimple through native integrations and APIs.
For Shopify specifically, BSimple offers deep integration:
- Automatic product sync—create products in BSimple and push to Shopify
- Order fulfillment automation—orders flow into BSimple for processing
- Inventory adjustments sync both ways
- Customer data synchronization for unified customer records
For Amazon and other marketplaces, BSimple receives order notifications and decrements inventory automatically. When you receive new stock through a purchase order in BSimple, stock levels update across all connected platforms immediately.
The power of this integration really shines when you’re managing wholesale alongside ecommerce. Many Australian businesses sell B2B wholesale to retailers and cafes while also selling direct-to-consumer through Shopify. BSimple handles both from the same inventory pool, giving wholesale customers dedicated ordering portals while keeping your online store stocked appropriately.

Ecommerce Fulfillment and Xero Integration
Orders coming from multiple channels need to be fulfilled efficiently, and every transaction needs accurate accounting. BSimple connects the dots between sales, inventory, fulfillment, and financial reporting.
When an ecommerce order arrives—whether from Shopify, Amazon, or your B2B portal—BSimple captures the order details and creates a pick list for your warehouse team. Once fulfilled, the order syncs to Xero as an invoice with the correct inventory COGS calculations. Your bookkeeper sees accurate financial data without manual entry.
Xero integration benefits for ecommerce:
- Automatic invoice creation: Every sale becomes a Xero invoice with correct line items and pricing
- Accurate COGS tracking: Inventory costs flow through to Xero for proper profit calculation
- Payment reconciliation: Match Shopify payouts and marketplace settlements to Xero transactions
- GST compliance: Ensure Australian tax obligations are met with proper reporting
For ecommerce businesses, this level of automation eliminates the nightmare of manual end-of-month reconciliation. You’re running a high-volume online business—you shouldn’t be spending days matching transactions and correcting inventory values in your accounting system.

Frequently Asked Questions
Can BSimple sync inventory across Shopify and Amazon at the same time?

When inventory is sold on any channel, BSimple updates stock levels across all connected platforms in real-time. This prevents overselling and keeps all your sales channels accurate.
How does BSimple prevent overselling when stock is low?
BSimple uses real-time inventory synchronization to update all sales channels immediately when a sale occurs. If you have 2 units left and someone buys on Shopify, BSimple instantly updates Amazon, eBay, and other channels to show only 1 remaining. The system processes inventory changes within seconds to minimize the risk of overselling.
Can I reserve inventory for wholesale customers while selling on ecommerce?
Yes, BSimple allows you to set aside buffer stock for specific customers or channels. You can dedicate a portion of your inventory to wholesale B2B orders while allowing the remaining stock to be sold through ecommerce platforms. This ensures your important wholesale relationships have priority access to inventory.
Does BSimple handle ecommerce orders from international marketplaces?
BSimple is designed primarily for Australian businesses, but it can manage inventory for international marketplace sales. The system tracks inventory regardless of where the sale occurs and integrates with Xero for multi-currency accounting. If you’re selling internationally through Amazon or other global platforms, BSimple keeps your inventory synchronized.
What happens to my Xero accounting when I sell through multiple channels?
BSimple consolidates sales from all ecommerce channels and creates unified invoices in Xero. Each sale—regardless of whether it came from Shopify, Amazon, or a B2B portal—generates the appropriate Xero invoice with accurate COGS and inventory tracking. This gives your bookkeeper a clean, consolidated view of your ecommerce revenue without manual data entry.
How quickly can I set up BSimple for my existing Shopify store?
Most Shopify integrations are completed within a few days.
