Laravel project customization

We need to add a way to have multiple options/variables for item with multiple selections. For instance, if units/Milligrams are selected and the item has 3 different unit size, there should be a way to add these in "Add Item" instead of duplicating the item 3 time based on unit size. Also, they would be able to select the different unit sizes for the same item in the Sales Order process. Per Station/User Login and Role Permissions.

Also, there needs to be a minimum order amount set for $1,000 and no order can be made until the items add up to at least $1,000. This process is exactly like the Sales Order process but only to place a Sales Order by the customer. It needs restrictions and must be simple. Right checks, banking, inventory audit Total Cost overall cost on the dashboard Router Switch Payroll option Vendor Checks, Walk-In checks
