In new sales approaches, salesperson performance is discussed and examined in three main dimensions: sales behavioral performance, non-sales behavioral performance, and outcome performance. The aim of the present study is to determine the impact of meaningful work on outcome performance, sales behavioral performance, and non-sales behavioral performance of B2B salespeople in the country's electronic banking industry. The research method is applied in terms of purpose and descriptive-survey in terms of data collection method. The statistical population of this study is B2B sales and marketing employees of four state-owned banks including Mellat, Melli, Tejarat and Saderat in Tabriz city. Based on stratified random sampling with proportional allocation, questionnaires were distributed among 175 B2B salespeople from the four aforementioned banks and the research data was analyzed using structural equation modeling with Smart-PLS3 software. The results showed that meaningful work has a positive and significant effect on the resulting and behavioral performance of sales and non-sales behavioral performance of B2B salespeople. Also, meaningful work has a positive and significant effect on the resulting performance through the path of sales behavioral performance and non-sales behavioral performance. Finally, as an innovation of the present study, it can be stated that in recent research conducted in the field of work and work environment, there is special attention to the meaningfulness of the work of employees in different departments of the organization, including sales. However, scientific research that examines meaningful work in three different dimensions of salesperson performance has not been reported.
