If your supplier is not in SupplyMaster's list of built-in integrations, you can submit a Custom Supplier request. Our support team will assess the supplier and configure the integration on your behalf.
When to Use a Custom Supplier
Use the Custom Supplier option when:
Your supplier is not listed in the supplier type dropdown.
Your supplier provides product data via a file format (CSV, Excel, XML) rather than a standard API.
You have a private or niche supplier that requires a custom integration.
How to Create a Custom Supplier
From the Manage Suppliers page, click Add Supplier.
Below the supplier type dropdown, click the Create Custom Supplier button.
Enter a Supplier Name (e.g., "My Supplier - Custom").
Fill in any available credentials. All three fields are optional:
Username — if the supplier provides one
Password — if the supplier provides one
Additional Info — any extra details, URLs, API keys, or notes that may help our team set up the connection
Click Save Supplier.
There is no Test Connection step for custom suppliers — the connection is configured by the support team after you save.
What Happens Next
After you save a custom supplier, our support team is notified and will:
Assess the supplier and the data format available.
Configure the integration on the backend.
Email you an update within 3 business days.
Once the setup is complete, products from your custom supplier will appear in your SupplyMaster account.
Limitations
Custom suppliers work differently from built-in integrations. The following features are not available for custom suppliers:
Feature | Available? |
Auto Import / Automatic Sync | No — syncs are managed by the support team or via manual file upload |
Product Fetch (pull from supplier API) | No — products are imported via file |
Browse Catalog | No |
Test Connection | No |
Duplicate Supplier | No |
Manage Orders | No |
AI+ Enriched Data | No |
Inventory Settings, Product Settings, Advanced Settings tabs | No — only the Connection Settings tab is shown |
Despite these limitations, custom suppliers still benefit from SupplyMaster's product management, field mapping (once configured by support), and Shopify integration.
