By default, SKULabs sorts items on the single orders picking screen by location name. If items are found in the same location, they will sort by SKU.
SKULabs also features the ability to control how line-items are sorted when picking orders on an order's details page. Simply add one of the flag variables below to the pick list template in your manual store(s):
SORT_BY_LINE_ITEM_SORT_STRING: (BigCommerce only) Relies on a custom line-item sorting string being imported from your sales channel.
If you need more granular sorting behavior, please reach out to support in chat for help configuring a custom sort string.
