The opposite of sandbagging in sales is often referred to as "frontloading" or "front-loading." Sandbagging involves intentionally holding back or downplaying one's performance or potential to exceed expectations later on. Frontloading, on the other hand, involves presenting one's capabilities, achievements, or projections in a more optimistic or aggressive manner upfront, to set high expectations from the outset. Essentially, while sandbagging involves under-promising and over-delivering, frontloading entails over-promising (to some extent) with the intent to meet or exceed those expectations. Both approaches carry risks and ethical considerations in sales practices.
