Contract Balances

Generally, all sales are contract sales (with either an underlying contract or purchase order). The Company does not have any material contract assets. When invoicing occurs prior to revenue recognition, a contract liability is recorded (as deferred revenue on the consolidated balance sheet). Revenues that were included in the beginning balance of deferred revenue during the three and six months ended June 30, 2023 were $157,000 and $519,000, respectively. Short-term deferred revenues were $986,000 and $782,000 at June 30, 2023 and December 31, 2022, respectively. Long-term deferred revenues were $758,000 and $911,000 at June 30, 2023 and December 31, 2022, respectively.
