Here are 2 ideas :

Option 1 : using key tag label sticker

• Print one more key label to stick on a part, a shelf or a bin
• PS print a key tag and fold it in of over a paper clip

Option 2 : using numbered bin

• When you received parts, put them in a bin Ex Bin 8
• In your POS, open the WO and on the first job at the end of the description add :" Bin 8"
  • Use transparent plastic bin
