My wife and I took on a project for our school and we are taking it from manual tracking to similar to retail tracking. We purchased a dymo 450 turbo printer for upc labels and a nadamoo scanner to read them and we are trying to get this all set up in excel to read the in and out to track everything. We are seeking assistance/help on how to set up the functions or formulas to track this. It is for an education program and it is non profit. If anyone has suggestions we are open. We are hitting the wall on this. We have been looking online and a lot of the suggestions send us in a lot of different directions.
