Get in touch with your loyal (and solvent) customers. Immediately! Anticipate how the troubled economy might affect them, because it will. Preempt trouble and engender even deeper loyalty by crafting some new pricing schemes. Take another look at long-term contracts. Assuming they haven't fallen on especially hard times, find creative ways to allow valued customers to keep buying. Worse case scenario, accept products or services in lieu of payment. Above all, keep a positive attitude and serve your customer with a smile!
