Tab 7: Variants Matrix Studio

Ultimate Enterprise Feature ($199)

The Variants Matrix Studio tab (#variants) provides enterprise multi-attribute combination management. It transforms standalone product options into an inventory matrix where every permutation (e.g. Red / XL / Cotton) possesses its own SKU, physical warehouse stock count, and price override.

1. Overview​

From the Variants Matrix Studio, store administrators configure:

  • Matrix Generation: One-click permutation engine generating all cross-combinations from configured options.
  • Unique Variant SKUs: Assign specific bar-code or warehouse SKUs to each individual combination.
  • Per-Variant Stock Levels: Manage exact stock numbers per combination (e.g., 12 in Red/M, 0 in Red/L).
  • Price Overrides: Set custom gross prices for specific combinations overriding base price calculation.
  • Combination Activation: Toggle individual combinations on or off without deleting the underlying options.

2. Before You Start​

  • Prerequisites: Configure at least two option groups (e.g. Color and Size) in Tab 6: Options & Variations.
  • License Requirement: This tab is exclusively available in FlexExt Store Ultimate Enterprise . On Basic Starter, Standard Commercial, or Pro Commercial tiers, the tab displays an informational upgrade lock badge.

3. Where to Find It​

  1. Open the Product Editor (index.php?option=com_flexext_store&view=product&layout=edit&id=1).
  2. Click the seventh tab in the navigation bar: Variants Matrix (#variants-tab).

4. Step-by-Step Configuration​

1

Generating Combinations

Click the blue Generate Matrix Combinations button. You should see: The engine cross-multiplies all options from Tab 6 and populates the table with every permutation (e.g., Black/S, Black/M, White/S, White/M).

2

Assigning Variant SKUs

For each combination row, enter its dedicated warehouse identifier in the Variant SKU column (e.g., SHIRT-BLK-S). You should see: These SKUs are used on order confirmations, picking slips, and PDF invoices.

3

Setting Exact Inventory Counts

In the Stock column, enter the exact quantity available for each combination. You should see: Real-time stock is tracked independently. Depleting Black/S does not impact White/S.

4

Applying Custom Price Overrides (Optional)

If a specific premium combination costs more (e.g. XL costs $59 instead of the base $49), enter the full price in Price Override. Leave blank to inherit base price + option modifier. You should see: Selecting that combination on the storefront will instantly load the override price.

5

Saving the Matrix

Click Save in the top action bar. You should see: The matrix is compiled and stored in #__flexext_store_variants.

6. Storefront Result​

On the storefront product page:

  • As shoppers pick option pills (e.g., selecting Color: Blue, then Size: L), the system checks the matrix in real-time.
  • The displayed SKU changes to SHIRT-BLU-L.
  • The live stock status indicator updates (e.g., "Only 3 left in Blue / Large").
  • If the customer selects a combination that is disabled or has 0 stock, the Add to Cart button disables with an appropriate prompt.

7. Tips & Best Practices​

Generate Only Needed Attributes

Only create options in Tab 6 that actually influence inventory or pricing. Secondary text fields (like custom gift notes) should remain standalone options rather than being compiled into the variant matrix.

Regenerating the Matrix

Clicking Generate Matrix Combinations when you have existing combinations will preserve matched existing rows and append new permutations. To completely rebuild from scratch, clear the matrix table before regenerating.
