What occurs when the deposit total exceeds the order amount?

When the deposit total exceeds the order amount, the correct action is that the excess deposit can be applied to any invoice. This functionality in NetSuite allows for flexibility in managing customer deposits and outstanding invoices.

This means that if a customer has overpaid via deposit, rather than being refunded or voided, the excess can be reallocated to other open invoices the customer may have. This approach streamlines the accounts receivable process, allowing businesses to efficiently manage customer balances and ensure that funds are utilized towards satisfying other debts the customer owes, rather than needing to track a refund or a void on the deposit.

The other options do not align with the system's ability to provide practical solutions for handling excess deposits. For instance, stating that the excess cannot be applied anywhere would limit the utility of deposits and create unnecessary complications in financial management.
