hi
no you don't. trust me.
you want to create catagories for your products with 2 or 3
characters(letters or numbers so long as it follows a logical order) to
start. you may want a seperator such as a dash(-) then products numbered
sequentually. this brings some sort of order to your inventory numbering
system.
you can then manage your inventory by catagory(smaller groups) instead of
trying to digest the whole inventory at one time.
opinions do vary on this topic as to methodology but some sort of order to
the inventory system is paramount. avoid anything and everything that has
something to do with "random".
