How can you make sure that all office supply transactions are divided evenly between the finance department and the public relations department?

To ensure that all office supply transactions are divided evenly between the finance and public relations departments, establish a systematic tracking method, such as using a shared ledger or spreadsheet that records each transaction along with the associated department. Implement a policy that mandates splitting costs for shared supplies, and review transactions regularly to confirm compliance with this policy. Additionally, consider using project codes or department identifiers in your accounting software to automate the division of expenses. Regular communication between departments can further help maintain transparency and accountability.
