Whether the deduction is part of a promotional campaign, a simple error or a dispute, it's a true testament to the fact that nobody's perfect, mistakes can happen and things can often go slightly awry because of them. Deductions, however, add up and, if the causing factors are left untreated, can snowball into a major drain on a company's profit. Dealing with these preventable claims requires thorough, company-wide involvement but could wind up saving everyone a great deal of stress and lost profit. Ken Green, president of IAB Solutions LLC, recommended establishing a policy for preventing deductions. Since a deduction is an issue that touches many different aspects, collaboration and the mutual sharing of information between departments is integral to a reduction in deductions and chargebacks, and not just collaboration between credit and sales. In addition to internal collaboration, Green suggested group visits to key customers in order to allow each particular department understand what the customer expects of them.
