Whats the main difference between Inventory Count, and Inventory Adjustment Worksheet guys? Just about to start a new inventory implementation and I'm not sure which transaction to use to get my inventory into the system.

For loading inventory into a new system, I'd use a Worksheet or simply an Inventory Adjustment. Inventory Count is meant for "trueing up" inventory counts when doing a physical/cycle count. In general I'd use Inventory Adjustments when doing inventory entries. Inventory Worksheets can be a little dangerous in that they change your balance to the number you have in your spreadsheet. Meaning if you put in 10 of Item A and there's currently 100 of Item A in your system, it will decrement your inventory by 90 to get to the 10. I'd be careful about using them (or not use them) outside of your initial inventory load. Inventory Adjustments you can just do a plus or minus to add/subtract the quantity you want.

You turns up you cannot do a multi-location CSV import using inventory worksheet anyway. We have about 50 locations so I cant do that import 50 times! Sounds like Inventory Adjustment is the way to go then. Thanks for the input @RJMNS!
