I use Square for sales out in the field as well as for some inventory management.
I have a part that has old superseded SKU numbers, but my service manuals still refer to these old SKUs.
What is the best way to keep track of these superseded SKUs, so they refer back to the new SKU as well as keep track of how many of each I have in stock and notify me when stock is low
For example, I have a part ELE-015-011 (1 in stock) that superseded part ELE-014-010 (2 in stock) that superseded ELE-014-005 (0 in stock)
I need to keep 2 in stock (combined total).
I tried to use variations, but it notifies me that because I only have 1 or the newest part (ELE-015-011) I am low on stock, even though I have 3 total in stock.
I hope this all make sense and someone can point me in the right direction.
