Discounts reward the people who pay for goods or services, not the people who buy or use them, and if they are not the same person, are an ineffective form of incentive. This is one area where a B2B incentive is very different to a B2C incentive, where the consumer is usually both buyer and user of the service or product being sold.
An incentive scheme aimed at increasing sales should always be aimed at those who make buying decisions.
Extending this further, it is clear that an incentive that is based on rewards rather than on discounts should be targetted at individuals, not organisations. If the people making the buying decisions are not the ones receiving the reward, then it is obvious that the reward has no influence to the person buying that service or product. There is no added incentive for them to buy that brand, or from that supplier, or to buy more, or a better model – the reward has no effect.
Only individuals can be influenced to change their behaviour through the emotional lure of a reward. Considered in the abstract, organisations make decisions based entirely on logic. But individuals within that company will still act emotionally. Buyer Decision Processing is still an emerging field of cognitive science.
There is no point in rewarding a company, you should be rewarding the person within the company who makes the choice to buy from you. Rewarding customer loyalty involves engaging individuals.
