SKUs

Why doesn't Lightspeed require them or generate them?

    Hey @unrealcity

    While Lightspeed doesn't populate the SKU field with any data, it does auto generate a System ID for each item. The SKU fields are intended for anyone to put their own SKUs should they need them. They are not "required" fields because not everyone uses them, some people operate solely off of Descriptions and manual searches.


    Hope this helps!

    But LS does require you to print a barcode when using the label print feature. You'd think if not requiring a sku it would give the option to remove the barcode.

    Hey @EricaC


    It's not quite that Lightspeed Requires you to print a barcode but rather that the System ID number is generated into a barcode that gets permanently attached to the item's label section unless you custom-code it to disappear. (This is usually done by a custom-coding firm or 3rd party coder)

    And what is the make up of the barcode?

    It looks like it is the system id with an extra digit at the end.

    What is the meaning of the last character?

    Hey @john_2084


    The makeup of the barcode is based off of the symbology which is EAN-13, with us. There's an equation that determines the barcode number, but this isn't something we would have within the software, those identifiers should be the system ID with that symbology associated to it.


    Hope this clarifies things!

    Vanessa,

    Right, so it is an EAN-13 barcode.

    The first 12 digits are the System ID of the product.

    What does the thirteenth digit represent?

    Hey @john_2084


    The 13th digit is a check-digit that, as I mentioned, is based off of a calculation of the previous 12 numbers.


    To calculate it manually, you can use this chart : https://www.gs1.org/services/how-calculate-check-digit-manually


    Since it's a calculation, it'll vary by the previous numbers.


    Otherwise, if you put your SystemID codes in an excel spreadsheet on cell A2, ou can use this excel formula to help you determine it.

    =MOD(10-MOD((MID(A2,12,1)+MID(A2,10,1)+MID(A2,8,1)+MID(A2,6,1)+MID(A2,4,1)+MID(A2,2,1))*3+MID(A2,11,1)+MID(A2,9,1)+MID(A2,7,1)+MID(A2,5,1)+MID(A2,3,1)+MID(A2,1,1),10),10) 
    
    

    This formula gives the code concatenated with the check digit (considering that the code in on the cell A2):


    =A2&(MOD(10-MOD((MID(A2,12,1)+MID(A2,10,1)+MID(A2,8,1)+MID(A2,6,1)+MID(A2,4,1)+MID(A2,2,1))*3+MID(A2,11,1)+MID(A2,9,1)+MID(A2,7,1)+MID(A2,5,1)+MID(A2,3,1)+MID(A2,1,1),10),10))
    

    Hope this clarifies :)

    Is the check digit the same for other formats. You use EAN-13, I would like to use Code 128.

  • VanessaDVanessaD Moderator, Lightspeed Staff Posts: 166 moderator

    Hi,

    Since the system ID codes are in EAN-13, this information is accessible to us, but for code 128, we don't have this information.


    Hopefully someone on the community is familiar with Code 128 and can answer this !

    If the barcode form allow for external Javascript then you can always use something like this for generating them --> https://lindell.me/JsBarcode/.
