Retail is a small part of most studios and a large part of the surprise at month end. A protein powder sells out, a shaker disappears, a supplement expires, and nobody can say whether the difference is sales, theft, or a counting error.
A simple count routine keeps the numbers explainable without turning the front desk into a warehouse team.
Count the Same Way Every Time
Choose a schedule, usually weekly or twice monthly, and count the same categories in the same order. Record the date, the counter, and the location. Use the shelf or bin layout as the count sheet so the physical count and the record match.
A count that follows a different order every time will produce phantom differences.
Record Opening, Sales, and Closing
The count alone cannot explain a difference. Record the opening count, the sales for the period, the closing count, and any known adjustments such as a damaged item or a staff purchase. The unexplained difference is the shrink.
Where the point-of-sale system tracks sales, reconcile the system total against the physical count rather than retyping sales.
Set Reorder Points Before You Need Them
For each item, record the reorder point and the order quantity. The reorder point should account for the supplier's lead time and the sales rate. Record the supplier and the order cadence.
A stockout during a peak week is usually a planning failure, not a counting failure.
Treat Adjustments as Decisions
Damaged, expired, donated, or used-for-demo items need a record and an approver. Record the item, the quantity, the reason, the date, and who approved it. Do not adjust the count silently.
Expiry dates matter for supplements and drinks. Record the earliest expiry and rotate stock so the older items sell first.
Keep the Display and the Stockroom Consistent
If the display is replenished from the stockroom, count both and record the transfer. A display that is not counted hides the stock that is actually available.
Handle the Common Situations
The count does not match the system. Recount before adjusting. Then check for unrecorded sales, transfers, or damages.
A supplier short-ships. Record the receipt, the shortfall, and the follow-up with the supplier before the invoice is approved.
An item is discontinued. Record the remaining stock and the sell-down plan. Do not reorder automatically.
A staff member buys at a discount. Record the sale and the approval.
Report Monthly
Report sales, closing stock value, shrink, and stockouts. Keep the report short and comparable month to month. The trend matters more than any single count.
A reliable count is mostly consistency. When the schedule, the sheet, and the adjustment rules are the same every period, the differences mean something and the studio can act on them.
