How to Sell Different Pack Sizes With One Barcode
Use these instructions to sell multiple size formats using the same UPC barcode. Typical examples include:
- 6-packs and 8-packs with the same barcode
- 4-packs and singles with the same barcode
Barnet allows you to place a prefix number in front of an existing UPC to trigger a prompt at the till. When scanned, staff will be able to select which size is being sold.
System Setting Required
Before configuring barcodes, verify that the system setting is enabled:
POS Manager > Setup > Preferences > General > Advanced
✔ Ensure “Message for 6–8 Pack” is enabled.
Note: This setting controls both 6/8 pack prompts and 4/single prompts.It is normally enabled by default, but Barnet Support can assist if needed.


Product Maintenance Setup
Each size format requires its own unique CSPC(SKU). Use the registered CSPC(SKU) when possible, even if you never purchase that format, for clean reporting and future ordering.
When you need to create a made-up CSPC
If the format does not officially exist (e.g. creating a 6-pack from an 8-pack):
- You may create a CSPC using letters or numbers
- Check the BDL website for correct CSPCs when they exist
Examples (Molson Canadian 6PK)
MOLCAN6697888PK6(697888= real CSPC for Molson Canadian 8PK in AB)
Best practice for 4-pack → single format
When creating a single from a product sold as a 4-pack, add an “s” to the end of the CSPC.
- 4PK CSPC:
34053 - Single CSPC:
34053s
Barcode Setup Rules
To activate the pop-up selection at the till, barcodes must be configured in a specific way.
6-Pack & 8-Pack (same manufacturer barcode)
- Use the real barcode for the 6PK
- Add an 8 to the front of the same barcode for the 8PK
Example: Molson Canadian
| SKU | Barcode | Description |
|---|---|---|
697888PK6 |
56327073203 |
Molson Canadian 6PK |
876888 |
856327073203 |
Molson Canadian 8PK |

4-Pack & Single (same manufacturer barcode)
- Use the real barcode for the 4PK
- Add a 1 to the front of the same barcode for the single
Example: Powell Brewing
| SKU | Barcode | Description |
|---|---|---|
4195 |
875463007213 |
Powell Dive Bomb Dark Ale 4PK |
4195s |
1875463007213 |
Powell Dive Bomb Dark Ale Single |

At the Till
- When either barcode is scanned, a pop-up will appear
- Staff will be prompted to choose which format they are selling
- Select the correct size and continue the sale as normal
This ensures accurate inventory movement and sales reporting without needing separate barcode stickers or manual overrides.
