Question

Front desk sells gloves, protein, or accessories and later needs to handle a return.

Before sale, open Retail Management or POS and confirm the product has an active SKU, barcode, price, and published sellable SKU for the correct gym.
Open SKU Inventory detail if stock is uncertain and verify On Hand, Reserved, Available, and Recent Movements.
Click Checkout, choose Gym, select Customer or Walk-in customer, choose Sellable SKU, Quantity, Collection Mode, Reference if offline/terminal, and Notes.
Complete Checkout only when Total matches the item and collection method. The sale should create retail order, invoice/payment evidence, stock decrement, and audit movement.
For a return, click Record Return from inventory detail or Retail return drawer, choose Gym, Customer or Walk-in customer, Retail SKU, Invoice ID when known, Quantity, and Reason.
After return, confirm stock increases and finance/sales-return reporting can explain the returned item.

Retail sale, money collection, stock movement, return reason, and audit history all match the real counter transaction.
