Marketing and sales go hand in hand as one handles market entry and the other leads the complete sales process.
The two feed off each other; while marketing can provide leads for sales teams, sales can communicate all received feedback that would influence the marketing strategy.
Moving in the same direction, the two seek to retain existing customers and acquire new ones to increase turnover rates and market shares. To that end, the two must be consistent in terms of plans and actions, and clearly agree on the target public and market, as well as on the objectives to be achieved. Marketing and sales must, therefore, clarify their respective roles in achieving common objectives. Finally, common feedback is, also, needed to monitor KPIs, validate the impact of actions taken and, if necessary, readjust the action plan accordingly.
