Importing item updates using CSV import

[pfullarton]

We have a central system that maintains our item master records and we load new items using the CSV import function with a suitably formatted CSV extract from that system.  Our central system facilitates price changes, description changes, etc. across the various departments in the business.  Using the CSV file I have that works for NEW items, am I able to use the same CSV item import function to update existing items (new prices, etc.) as well as adding new items?

To make it clear,, do you want to update the items list with new items using a csv file without duplicating data??

We have item changes daily.  This includes new items, changes to existing items, starting stock, etc.  Am I able to EXPORT all item every day and import the whole file, over-writing ALL items that exit in in the Loyverse POS database?
