Why might a cashbook not include a cash column?

The correct answer indicates that a company might not include a cash column in its cashbook because it keeps a limited amount of cash on its premises. This suggests that the company may primarily operate through other forms of transactions that do not require frequent cash handling, thus deeming a dedicated cash column unnecessary.

By having minimal cash on hand, the company can streamline its record-keeping processes and focus on controlling bank transactions instead, as cash transactions could be very few or insignificant.

In contrast, the other options highlight scenarios that might not warrant the exclusion of a cash column. For instance, if a company does not deal in currency transactions or prefers to use online banking exclusively, they might still have occasional cash inflows or outflows that would need to be recorded, even if infrequently. Similarly, avoiding cash transactions altogether provides no cash for record-keeping but doesn't necessarily align with limited cash on premises; it would instead imply a completely different operational approach. Thus, focusing on the aspect of having limited cash directly addresses the practicality of maintaining a cash column in a cashbook.
