Final answer:
The most efficient and accurate method for a retailer like Street Smarts to manage daily sales data during the peak tourist season is through source data automation, which minimizes errors and expedites processing.
Step-by-step explanation:
The best way for Street Smarts (SS) to ensure that sales data entry is efficient and accurate during the peak season is B) source data automation. This method utilizes technology to capture and enter data into the computer system directly from the point of origin, which in this case is the point of sale. Source data automation tools include barcode scanners, card readers, and point of sale (POS) systems. These tools help reduce human error, increase the speed of transaction processing, and enhance the accuracy of the sales data.
Well-designed paper forms may be more prone to human error, turnaround documents are typically not used in daily sales, and while sequentially numbered sales invoices can be helpful for tracking, they do not inherently improve the efficiency and accuracy of data entry as compared to automated systems.
