How to Allow Negative Amounts for Service Items


Negative Amounts on Sales Orders and Invoices can only be applied to service-type items, not product-type items. This restriction ensures accurate inventory management, as negative quantities on physical products could disrupt stock levels and complicate financial reporting. Since services do not require inventory tracking, they are the appropriate choice for adjustments such as discounts, credits, or refunds.
