Setting up unit conversions for different vendors offering the same item in varying packaging sizes can be approached in a couple of ways, depending on your specific needs and the capabilities of your inventory management system. Here are two common approaches you can consider:
Single Intra-Class Conversion: You can create a single intra-class conversion from the base unit (e.g., Each) to the common unit of measurement (e.g., Box) and handle the different packaging sizes through trade agreements or vendor-specific pricing. In this case, you would create a conversion from Each to Box, and then manage the different quantities within the Box through pricing agreements with each vendor.
Multiple Intra-Class Conversions: Alternatively, you can create separate intra-class conversions for each vendor's packaging size. For example, you would create one conversion from Box50 to Each and another from Box100 to Each. This approach allows you to directly convert between the vendor-specific packaging sizes and the base unit, which can be helpful for more granular inventory management.
