Filing by which method is typically used for general files like invoices and correspondence?

Filing by subject matter is typically used for general files like invoices and correspondence because it allows for an organized and intuitive way to categorize documents based on their content or topic. This method focuses on the context of the documents, making it easier for staff members to locate and retrieve files related to specific subjects or issues.

When using a subject matter filing system, documents are grouped according to themes or topics, such as by department, type of transaction, or specific projects. This way, related documents are kept together, which can enhance efficiency and ease of access. For example, all invoices related to a particular client can be filed under that client's name, making it straightforward to find all relevant correspondence and financial records.

Other filing methods, like by numbers or date, have their specific uses but do not provide the same level of context for general files like invoices and correspondence. Number-based systems might be more suitable for tracking inventory or account numbers, while date-based filing could serve records that depend on chronological order, such as project timelines or dated correspondence. However, neither method emphasizes the subject matter, which is often crucial for business communications and records management.
