Choose two answers. A zero dollar sale is showing up in your statistics. It means that:

A zero-dollar sale typically indicates a transaction with no monetary value exchanged, which can occur in two primary scenarios. First, when a client activates a free trial, they gain access to the service without an immediate charge, thus registering as a "sale" with a zero-dollar value. This allows tracking of trial activations within sales metrics. Second, if a customer purchases a service and then promptly cancels it, the initial transaction might be recorded, followed by a refund or cancellation that effectively nets out to zero dollars. This can appear as a zero-dollar sale in some systems, reflecting the initial intent to purchase and subsequent reversal. A non-standard payment plan would still involve a payment, even if deferred or customized, and therefore would not result in a zero-dollar sale.
