I cannot delete a particular inventory item
MainBoss Basic won't let you delete an inventory item if MainBoss's records indicate that you still have some of that item on hand. To delete the item, you first have to reduce the count to zero wherever the item is stored (you can check inventory using Inventory->Item Inquiry). You can do this using Inventory -> Adjustments->Physical Count. Reduce the count to zero, then try deleting the item again.
