Revenue is recognized when obligations under the terms of a contract with our customer are satisfied. Generally, this occurs when we transfer control of our vehicles, parts, or accessories, or provide services. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. For the majority of sales, this occurs when products are shipped from our manufacturing facility. At the time of revenue recognition, we reduce the transaction price and record a sales return and allowance reserve against revenue for estimated variable considerations related to future product returns. Such estimates are based on an analysis of known pending returns and historical experience. We adjust our estimate of revenue at the earlier of when the value of consideration we expect to receive changes or when the consideration becomes fixed.
Sales and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. The expected costs associated with our base warranties and field service actions are recognized as expense when the products are sold. We do not have any material significant payment terms as payment is received at or shortly after the point of sale.
We have elected to recognize the cost for freight and shipping when control over vehicles, parts, or accessories has transferred to the customer as an expense in Cost of Sales.
Deferred revenue is related to any non-refundable amounts that are collected from customers related to our unsatisfied assembly services. Deferred revenue is recognized as revenue as the performance obligation is satisfied.
Deferred revenue is equivalent to the total service fee allocated to the assembly service performance obligations that are unsatisfied as of the balance sheet date. Deferred revenue was $4.9 million and zero as of September 30, 2022 and 2021, respectively.

Of the total deferred revenue for assembly services, we expect to recognize $3.4 million of revenue in the next 12 months.
Accounts Receivable
Accounts receivable primarily include amounts related to sales of our products and services rendered. We provide an allowance against accounts receivable for the amount we expect to be uncollectible. We write-off accounts receivable against the allowance when they are deemed uncollectible.
