Why invest in aftermarket information?
Aftermarket documentation is often underestimated, but when handled correctly, it becomes a powerful sales and marketing tool. Many companies understand the importance of good aftermarket information, and this article by the Harvard Business Review calculates that in America alone, aftermarket sales are worth approximately $1 trillion a year. But aftermarket information isn’t just a good sales tool – it helps improve many metrics in your business. Here’s some examples of how good aftermarket information delivers value:
- Increases customer satisfaction with accurate and easily accessible support information, when and where your customers need it.
- Helps you upsell and cross-sell ancillary products and services by highlighting upgrades, accessories, or complementary services for your products.
- Builds loyalty with your customers by helping provide a great after-sales experience.
- Reduces operational costs by lowering service calls and returns, and giving your customers the confidence to tackle issues themselves.
- Boosts your ROI by extending the value of your product long after the initial purchase and helping secure repeat purchases.
