Does anyone know if there is a way to mass delete customer records without inline edit or suitescript? I'm going to assume not but figured I'd ask.

Note that If there are any transactions or other records attach the customer record then you won't able to delete them. You can use the bulk select option by holding ctrl and click any inline editable field select all records and delete them all together.

I don't think there is an easy way to delete customers via mass update or the like. ALSO, Sam-I-Am is correct: if you have "transaction-tied" customers, you'd have to delete the transactions to delete the customers. Better to mark them inactive if that is the case.

Yeah, luckily its all customers with no dependent records. Looks like they just imported some duplicates in error(5000 to be precise) and wanted us to delete em. My other boss didn't want to turn on in-line editing so I ended up using a mass update script for it and we're all good. Thanks guys! you're the best!
