Inventory is the practice of stocking goods by manufacturers, retailers and wholesalers for future sale or use while trade credit is the purchasing of items without instantaneous payment due to offer of a credit period.

Deterministic models have to do with constant and known demand also in this case shortage will not be permitted and this can be associated with low setup costs.

Many deterministic inventory models have been formulated without trade credit or with one level of trade credit. In recent times, one of the problems of industrial and agro business is financial constraints. Government at different levels has intervened to reduce this problem by establishing industrial and agricultural banks that give loans to business men and women. However, many of those who need the loans do not have the necessary collateral security which the banks often ask for and many people find it difficult to keep the terms of agreements as regards the delay in time of payment.

From literature, it was observed that trade credit becomes an easier means of overcoming this problem hence this special issue will consider recent deterministic models in inventory under one and two levels of trade credit based on discounted cashflow and inventory inaccuracy since 1989. Finally, the significance and limitations of the study will be considered.
