Below is the setup and best practice process for managing drum deposits and returns in Lightspeed. 

Setup

• You first need to start with a Product, with inventory tracked or not (up to you), called 'Drum'. 
• For those purchase with the chemical + drum, you would create a composite (kit) that includes the chemical + the drum product

Selling

• Add customer to the sale
• Search and select the correct drum product
  • When selling the drum by itself (if you do this), you would just select the drum product. 
  • When selling the drum + chemicals, you would select the composite product (kit). 
• Process the sale as normal 

Returns

If the Original transaction is available:

• Locate the transaction the Sales History or scan the QR code on the receipt
• Click Return items
• Search the 'Drum' product (not the kit) to add to the refund transaction
• Adjust the qty to -1
• Remove the other items from the original transaction that are not being refunded (this is important to remove the kit, as it will return the chemical stock)
• Continue to refund the drum deposit amount (or put to store credit)

If no original transaction available:

• Navigate to the sell screen
• Add customer to the transactions
• Search and add the 'drum' product (not the kit) to the transaction
• Adjust the qty to -1
• Continue to refund the drum deposit amount (or put to store credit)
