🔥 [New] Introduction to Inventory Multi-Unit Management

Copy link & title

Update Time: 28 Aug 2025 03:09

In retail and supply chain operations, a single SKU often requires different units across scenarios. For example, pens may be purchased in boxes, stored in cartons, and sold individually.

With Inventory Multi-Unit Management, you can define base unit and multiple conversion units for the same SKU, and the system will automatically handle the conversions.
 
💡 For instance, if 1 box = 100 pcs and 1 carton = 1,000 pcs, then 2 cartons 5 boxes will automatically be recorded as 2,500 pcs in stock.

Part 1: Enable Multi-Unit Management

Multi-Unit Management can be enabled at two levels:

  • Global Switch: You can choose whether to enable multi-unit management across the entire system on Inventory Setting page.  

  • SKU-Level Switch: At the Merchant SKU level, you can still enable or disable multi-unit for individual SKU as needed on Merchant SKU Editing page.

(When system-wide multi-unit is enabled, SKUs will be enabled by default, but you can turn it off on Merchant SKU Editing page.)

Step 1: In System Settings > Inventory Settings > Multi-Unit Management, turn on Multi-Unit Management t across the entire system



Step 2: Add Unit


 
💡 Tip: When multi-unit is enabled, you must set a Base Unit (usually the smallest measurable unit, e.g., pcs). Other units (e.g., carton, box) will be converted automatically based on the Base Unit.
 

Part 2: Merchant SKU Setup

For each merchant SKU, you can configure the following settings on merchant SKU editing page.

1) Enable / Disable Multi-Unit Managemnet for Merchant SKU
At the Merchant SKU level, you can still enable or disable multi-unit for individual SKU as needed on Merchant SKU page Editing page. When system-wide multi-unit is enabled, SKUs will be enabled by default, but you can turn it off on Merchant SKU Editing page.

2) Base Unit (Required):
The smallest measurable unit of the product (e.g., “piece”). All other units are defined and converted based on this unit.


 
3) Conversion Units and Conversion Rules:

Additional units used in purchase, warehousing, or sales (e.g., “box,” “bundle,” “pack”). You must define how each conversion unit relates to the base unit (e.g., 1 box = 12 pieces). A single SKU can have multiple conversion units.


4) Purchase Unit:
The default unit used when making purchases in the purchase module (e.g., “carton” instead of “piece”).
5) Barcode Number:
Each conversion unit can have its own barcode (manual or auto-generated). Barcodes enable quick identification of the SKU and unit, streamline warehouse and sales operations, and reduce errors by automating unit conversion. The barcode number can be left blank if not needed.
 

6) How to Print Conversion Unit Barcodes
On Merchant SKU page, you can select merchant SKUs > Click Bulk Actions > Print SKU Label


 

After enabling multi-unit globally, the SKU label printing popup includes a new “Print Unit” field. If non-base units are added, labels can be printed using the corresponding conversion unit barcode:

  • Print Unit = Base Unit → Labels are printed according to the selected template using the base unit barcode.
  • Print Unit = Conversion Unit → Labels are generated using the conversion unit barcode.


Part 3: Changes After Enabling — Warehouse

1) Manual Stock-In / Stock-Out
  • On the editing page, Stock-In / Out quantities can be entered using conversion units, and the system will immediately display the equivalent quantity in the base unit.


  • In the list view, all Stock-In / Out Qty are automatically converted to the base unit Qty.
  • Printed documents display both the base unit quantity and the recommended units.
💡 Example: Assuming 1 carton = 1000 pcs, 1 box = 100 pcs

Base Unit Qty: 4,201 pcs

Recommended Unit Qty: 4 carton 2 box 1PC (4000 + 200 + 1)


2)  Inventory List
  • All quantities are displayed and calculated in the SKU’s base unit by default.
  • Option to display inventory quantity using conversion units

3) Transfer / Stock Count / Move / Restock

  • Quantities can be entered using conversion units, and the system will immediately display the equivalent quantity in the base unit.
  • Printed documents display both the base unit quantity and the recommended units.
4) Purchase & Transfer Receiving

  • Receive Quantity can be entered using conversion units, and the system will immediately display the equivalent quantity in the base unit.

  • Supports receiving items by scanning Conversion Unit Barcodes.



5) Purchase Suggestions
  • Suggested purchase quantity now includes a “Unit” field, allowing users to switch between different units. When switching units, the purchase quantity is automatically converted.

Part 4: Changes After Enabling — Order Processing

1) Order Details

  • SKU stock Qty are always based on the SKU’s base unit.

2) Manual Orders

  • Quantities can be entered using conversion units, and the system will immediately display the equivalent quantity in the base unit.

3) Document Print Template Settings: Pick List, Pack List, Summary List, and Customized Shipping Labels

  • The templates now support configuring: Base Unit, Conversion Unit, and Display Converted Quantity.
    • Unit: Bottle
    • Conversion Unit: 1 case 4 Bottle
    • Show Conversion Qty: (6+4)
