driven by the continued increase in active users on the company 's evidence.com platform . to gain more immediate feedback regarding activity for axon camera products and evidence.com services , we also review bookings for these products . we consider bookings to be a statistical measure defined as the sales price of orders ( not invoiced sales ) , including contractual optional periods we expect to be exercised , net of cancellations , placed in the relevant fiscal period , regardless of when the products or services ultimately will be provided . most bookings will be invoiced in subsequent periods . due to municipal government funding rules , in some cases certain of the future period amounts included in bookings are subject to budget appropriation or other contract cancellation clauses . although the company has entered into contracts for the delivery of products and services in the future and anticipates the contracts will be fulfilled , if agencies do not exercise contractual options , do not appropriate funds in future year budgets , or do enact a cancellation clause , revenue associated with these bookings may not ultimately be recognized , resulting
