<p>A customized payment policy is different than a generalized payment policy for a specific type of product. A deteriorating type of product has a shorter shelf-life than a traditional non-deteriorating product. Due to the short shelf-life, the customized payment policy for deteriorating products is market-driven, especially advertising. In that case, a generalized payment policy is not applicable for generating sales revenue. Besides, depending on the short shelf-life, pricing policy is contrariwise related to the time. The exponential rate of shortages is permitted with the waiting and the customer’s demand may vary according to a product's displayed stock and sales price, so the recent time value of money is calculated with a variable holding cost. The product demand function is defined as (1) non-deteriorating, (2) deteriorating, and (3) shortages. Three mathematical examples under dissimilar situations are specified, and the optimality is measured using the classical optimization approach with its graphical demonstration. The numerical outcomes reveal that under different circumstances, the optimal sales price ranges from $49.60 to $50.56 per unit, and the best frequency of advertisement varies from 1 to 3 times per cycle. The total profit achieves in the three cases ranges from $5,759 to $6,613, with the highest profit observed when the trade-credit period aligns with complete stock depletion. Sensitivity analysis further highlights that increasing inflation and preservation investment positively impact profit, whereas higher purchasing and holding costs reduce overall profitability. These insights provide a real-world background for retailers to improve their pricing, advertisement, and inventory decisions for deteriorating products.</p>
