Yes, you can edit your catalog after you’ve imported it into BeezUP. This is thanks to its Personalized Fields feature.
Enrich an incomplete product feed
Example: indicate the shipping costs even if they are not in your feeds.
Upgrade a field in terms of expected values
Example: turn a “1” in your source feed into “In Stock” for a specific network
Combine several fields
Example: turn your product title into the concatenation: “product name” + “color” + “brand”.
Modify a value in relation to multiple conditions
Example: run a 10% promotion on products of brand XX on marketplace YY.
Note that this will have no impact on your source catalog.
