What should you do before adding additional items to the opening balances template?

The correct approach before adding additional items to the opening balances template is to create the additional items in Xero first. This step is crucial because the opening balances template requires that any items you wish to include already exist within Xero’s inventory.

By creating these additional items beforehand, you ensure that the system can recognize and link any transactions or balances to their corresponding inventory items. This prevents errors or mismatches that can occur if you attempt to add items that have not been defined in the system. It also helps maintain data integrity and ensures that all relevant details related to inventory items, such as descriptions, pricing, and categorization, are accurately represented in your financial records right from the start.

The other choices do not provide the necessary step for proper setup before using the opening balances template. Removing existing items does not relate to the task of adding new ones, importing balances without any additions would not make sense if new items are needed, and editing item details for accuracy is important but it comes after you have ensured that all items are already created in Xero.
