It is necessary to check the subscription rates claimed by the agent for each and every title with the publishers rates which consumes the time and energy of the staff. The agents will not be able to know about the "non-receipt" till they are intimated by the subscribers, since the publishers supply the periodicals directly to the subscribers. Hence, some, agents decline to undertake the responsibility of arranging replacements for the missing issues.

Agents claim handling charges in case of periodicals published by learned societies and professional institutions, which do not offer agency commission. Institutions will remain in the dark about the non-receipt of subscription amounts by the publishers till they are intimated by the latter. The conversion rates for foreign currencies claimed by the agents have to 1: checked with the conversion rates circulated by the Good Offices committee from time to time. There are cases of subscription agents who create complications by refusing to take responsibility over claims for missing issues in violation of the agreement. In such cases the execution of the agreement is no remedy unless supported by a security deposit. The subscription agent has to be appointed after calling for quotations and selecting the lowest.
