There are several common bottlenecks in trial and sample processes: First, internal workflows are not optimized for small-quantity trial orders, so sales spend a lot of time coordinating to ship even a single batch, and prospects lose interest while waiting. Second, after samples ship, there's no systematic tracking of the prospect's feedback—follow-ups rely entirely on individual sales memory or notes, making it easy to lose information. Third, trial order terms (cost, quantity, lead time) are not standardized, requiring internal discussion each time, which is inefficient and error-prone. The improvement direction is to standardize the trial process—including minimum trial quantity, cost rules, and shipping timelines—and establish a mechanism ensuring that feedback from each sample shipment is recorded and becomes the basis for subsequent business discussions, rather than disappearing in email inboxes.
