Product Families (SynSets™)

Product Families, also known as SynSets™, allow you to group multiple individual SKUs and sell them together as a single unit. When a customer orders a SynSet, the system automatically deducts inventory from all included SKUs.

For example, you can create a “Gift Basket” that includes 3 chocolates, 2 candles, and 1 gift card. When someone purchases the Gift Basket, ShipEdge Core automatically reduces inventory of each individual item.

Simplifies Catalog

Sell multiple products as one without creating additional physical SKUs.

Automatic Stock Management

Inventory is automatically calculated based on component SKUs.

Increases Sales

Create attractive bundle and kit offers to increase average order value.

Total Flexibility

Configure specific quantities, shipping methods, and custom rules for each SynSet.

When you create a SynSet, you define:

  1. SynSet Name: A unique identifier (can be the same as an existing SKU or completely new)
  2. Included SKUs: The individual products that form part of the bundle
  3. Quantities: How many units of each SKU are included
  4. Available Stock: Automatically calculated based on component inventory

The system calculates how many SynSets you can form based on the SKU with the lowest available inventory.

Example:

If your “Holiday Bundle” SynSet includes:

  • SKU-A: 3 units (100 in stock)
  • SKU-B: 2 units (50 in stock)
  • SKU-C: 1 unit (80 in stock)

SynSet Available Stock:

  • SKU-A allows: 100 ÷ 3 = 33 bundles
  • SKU-B allows: 50 ÷ 2 = 25 bundles ← Limiting
  • SKU-C allows: 80 ÷ 1 = 80 bundles

Result: You can only create 25 Holiday Bundles before running out of SKU-B.

  1. Access the SynSets List

    Navigate to Inventory → Product Management and select the SynSets™ tab or link.

  2. Click “Create SynSet”

    On the SynSets list page, click the Create SynSet or Add SynSet button.

  3. Complete Basic Information

    • SynSet Name: Unique name to identify the bundle
    • Description: Detailed description of the SynSet (optional)
    • Mix Max: Maximum allowed quantity for mixing/combining (optional)
  4. Configure BOM SKU (Optional)

    The BOM SKU (Bill of Materials SKU) is a main SKU that represents the complete bundle:

    • If you specify a BOM SKU, the system will mark that SKU as “BOM” in the product catalog
    • Useful for integrating with external systems or marketplaces
    • The BOM SKU must exist in your product catalog before assigning it
  5. Select Shipping Method (Optional)

    If you want to use a specific shipping method for this SynSet, select it from the dropdown list.

  6. Enable BOM SKU QTY (Optional)

    If you enable BOM SKU QTY, the system will send BOM SKU quantities back to the marketplace or integrated system.

  7. Save the SynSet

    Click Save or Create to save the initial SynSet configuration.

  8. Add Component SKUs

    After creating the SynSet, you’ll be redirected to the Add SKUs page:

    • Search or enter each SKU you want to include
    • Specify the Quantity of each SKU
    • Click Add to add each SKU to the SynSet
  9. Review and Confirm

    Once all SKUs are added, return to the SynSets list to verify:

    • Automatically calculated available stock
    • Included SKUs with their quantities
    • BOM SKU and shipping method configuration

BOM SKU (Bill of Materials)

Assign a main SKU that represents the complete SynSet. Useful for integrating with marketplaces like Amazon or Shopify.

Mix Max

Define the maximum allowed quantity for mixing or combining SKUs in the SynSet. Control your bundle’s flexibility.

Custom Shipping Method

Configure a specific shipping method for the SynSet, different from standard methods.

Attached Instructions

Add special packing instructions or attachments to guide warehouse staff.

The BOM SKU is a “virtual” SKU that represents the complete SynSet in external integrations:

  • How It Works: When you assign a BOM SKU, that SKU is marked as “BOM” in your catalog
  • Main Use: Integrate with marketplaces (Amazon, eBay, Shopify) that require a unique SKU for the bundle
  • Requirement: The BOM SKU must exist previously in your product catalog
  • BOM SKU QTY: If you enable this option, BOM SKU quantities are synchronized with the marketplace

The system automatically updates SynSet available stock whenever:

  • Inventory is received for any component SKU
  • An order including the SynSet is completed
  • A component SKU’s inventory is manually adjusted

Stock Calculation Formula:

SynSet Stock = MIN(SKU Stock ÷ Required Quantity) for all SKUs

    The file will include:

    • SynSet name
    • Included SKUs
    • Quantities
    • Description
    • Calculated stock
    • BOM and shipping method configuration
  1. Prepare Your CSV File

    Use the previously downloaded format as a template. Make sure to include:

Descriptive Names

Use clear and descriptive names for your SynSets that clearly indicate what the bundle contains (e.g., “Summer-Beach-Kit”, “Gift-Set-Birthday”).

Monitor Limiting Stock

Regularly identify which component SKU is limiting SynSet stock and replenish it first.

Use BOM SKU for Integrations

If you sell on external marketplaces, always assign a unique BOM SKU to facilitate inventory synchronization.

Review Configurations Before Importing

Validate your CSV file before importing SynSets in bulk to avoid configuration errors.

Group Complementary Products

Create SynSets with products that are naturally used together to increase perceived value and sales.

Update Descriptions

Keep SynSet descriptions updated with promotion details, bundle benefits, or special instructions.

SynSet Stock Shows Zero Even Though I Have Inventory

Section titled “SynSet Stock Shows Zero Even Though I Have Inventory”

Problem: The SynSet shows stock 0 even when component SKUs have inventory.

Solution:

  • Verify that all component SKUs have available stock
  • Identify the SKU with lowest relative stock (available stock ÷ required quantity)
  • That SKU is limiting SynSet stock
  • Replenish the limiting SKU to increase SynSet stock

Problem: When trying to assign a BOM SKU, you receive an error or the system doesn’t allow it.

Solution:

  1. Verify that the BOM SKU exists in your product catalog
  2. Make sure the BOM SKU is not assigned to another SynSet
  3. If the SKU doesn’t exist, create it first in the product catalog and then assign it to the SynSet

Problem: When trying to add SKUs to the SynSet, they don’t save or an error appears.

Solution:

  • Confirm that SKUs exist in your product catalog
  • Verify that you’re entering quantities greater than zero
  • Make sure the SynSet name is not the same as an existing individual SKU (unless you intentionally want it)

SynSet Doesn’t Appear in External Integrations

Section titled “SynSet Doesn’t Appear in External Integrations”

Problem: The created SynSet doesn’t synchronize with your connected marketplace (Shopify, Amazon, etc.).

Solution:

  1. Assign a BOM SKU to the SynSet
  2. Enable the BOM SKU QTY option if the integration requires it
  3. Verify inventory synchronization configuration in the integrations module
  4. Review synchronization logs to identify specific errors

Problem: When trying to import a CSV file, you receive errors or SynSets don’t get created.

Solution:

  • Verify that the CSV file uses the correct format (download a template as reference)
  • Make sure all SKUs mentioned in the CSV exist in your catalog
  • Verify that quantities are valid numbers greater than zero
  • Confirm there are no special characters that break the CSV format
  • Unique Names: Each SynSet must have a unique name in your account. There cannot be two SynSets with the same name.
  • Unique BOM SKU: A BOM SKU can only be assigned to one SynSet at a time.
  • Real-Time Stock: SynSet stock is automatically recalculated whenever a component SKU’s inventory is updated.
  • Integrations: To synchronize SynSets with external marketplaces, make sure to correctly configure the BOM SKU.

Create SynSets for seasonal offers:

  • “Valentine’s Day Gift Set” (chocolates + flowers + card)
