How to import list & csv file, spreadsheets

i’m using another accounting app but it appears to be inefficient because i have to go to a special spreadsheet to to find the location of an item, i need to import approx 80’000 items & 100 addresses

Full details are on available imports are in the guide Use Batch Create and Batch Update functions

If by 80’000 items you mean 80,000 inventory items, then I am not sure that Manager is the software package you need but you can always setup a test business and try it out for free
