Key Terms for Amazon Vendors Using Base.com
Understanding how Base.com defines and uses key industry terms will help you navigate the platform more confidently. Below is a reference table mapping common terminology to what it means for Amazon Vendor Central sellers.
| Industry Specific terms | Meaning for Amazon Vendor Sellers |
| Seller | The supplier (you) selling to Amazon |
| Purchase Order (PO) | A buying document from Amazon Vendor Central |
| Split PO | A partial shipment linked to the original PO |
| Vendor ID | Auto-fetched identifier from Amazon |
Step-by-Step Integration Process: Connecting Amazon Vendor Central to Base
The integration process connects your Amazon Vendor Central account to Base.com in a few simple steps. This enables secure data syncing for orders, inventory, and product listings between both platforms.
Step 1: Initiate Integration in Base
- Log in to your Base.com account
- Navigate to the Integrations section
- Click on the green button + Add Integration
- In the popup window, type Amazon and select Amazon Vendor Central
Step 2: Connect to Amazon Vendor Account
- In the Integration tab, select the option: Connect Amazon Vendor Account IN
- You will be redirected to the Amazon login page
- Log in using your Amazon Vendor Central credentials
- Review the permissions requested by Base.com (includes access to orders, listings, inventory, pricing, and invoicing)
- Scroll down and click the Confirm button to authorize access to Base.com as a trusted third-party integrator
Step 3: Complete Integration Setup
- After successful authentication, you will be redirected back to Base.com
- Base.com will automatically populate the following fields:
- Region (e.g., India)
- Account Name (this field is customizable)
- Vendor ID / Merchant ID (fetched automatically)
- Click Save to finalize the integration. The integration is now active
Notes: The seller is selling directly to respective vendors using the Vendor IDs mentioned, which in the case of Amazon Vendor Central (AVC) operate on an invite-only basis. Each Vendor ID is unique to an Amazon-approved vendor account and must be verified before use.
Unlike Seller Central, where sellers list products themselves, Vendor Central works through Amazon-issued purchase orders (POs) tied to the Vendor ID. These IDs also govern catalog/ASIN mapping, logistics, compliance, and payments, so it is essential to confirm that the provided Vendor IDs are active, authorized by Amazon, and fully compliant with operational requirements before proceeding.
Features Enabled by the Integration
Once your Amazon Vendor Central account is connected to Base.com, the following functionalities become available:
| Feature | Description |
| Two-way Listing Synchronization | Create and update product listings in Base.com. Changes are automatically pushed to Amazon Vendor Central. |

Handling Multiple Delivery Invoices for a Single Purchase Order
Amazon may issue large POs that need to be fulfilled in parts. Base.com supports structured handling of multiple shipments and invoices under one PO.
How to Manage Split Deliveries and Invoices
1. Split the Purchase Order
- Within Base.com, split the original PO based on the quantities you are ready to ship
- Each split is treated as an independent shipment while still being linked to the original PO
2. Mark the Original PO as Partially Fulfilled
- After completing the first shipment, Base marks the original PO as partially fulfilled
- Remaining quantities stay open for future fulfillment
3. Generate Invoices Per Delivery
- Each split shipment allows for a separate invoice to be issued
- Helps maintain compliance with Amazon’s invoicing and payment processes
4. Automatic Stock Reservation
- Stock is reserved in real time for each shipment during the splitting process
- Ensures accurate inventory management and prevents over-committing
5. Tracking and Delivery Confirmation
- Each split includes label printing and tracking number export to Amazon
- Ensures Amazon receives updates on each partial delivery
