Frequent tendering does not create an opportunity to establish deeper relationships with the agency. In addition, it increases costs for both the client and agency, as well as uncertainty. If you frequently resort to tendering, your agency is probably not secure in its position and is constantly looking for new clients. Relationships suffer and you lose the benefits of long-term cooperation, especially the consistency of your brand communication. On the other hand, by approaching agencies directly, smaller clients have a better chance of landing a quality agency that might otherwise have refused to participate in a tender for a smaller project.
Time and cost savings that can be invested in building a confident brand consistently over the long term, instead of pursuing attractive short-term ideas.
