Hi, My customer has previously used "Payment Items" as item type when a Gift Card is used on a sales order. These gift cards can also be purchased as a "Non-inventory item". Due to the OSS installation, we are no longer able to mix items which have the possibility to activate OSS (the "Moss applies" checkbox) with items who don't have this possibility (confirmed by Netsuite support). My question is: Can I use a "Discount Item" instead of a "Payment Item" ? Is there anything I need to consider before making this switch? The same account will be used.

One thing to consider, is the Tax liability. For example, if you're not collecting the tax on the sale of the Gift Card, you'll need to not apply tax to the discount.

We do collect tax both when purchasing a Gift card, and when using it. Or do i missunderstand you here?

If you collect it on the sale of the card, and also collect the tax content on just the balance of the sale, then that's fine.

No. All items include tax (selling cloths)

The challenge with Gift Cards, is not knowing what's going to be purchased, so if you sell non-taxable Items, I've always found it easier to not charge Tax on the sale of the card and just calculate the tax at the time of the sale. If everything's taxable, then there's no issues.
