The following table reflects contract balances with customers (in thousands):

Accounts receivable, net$72,242 $62,069 
Deferred revenue, current93,230 80,824

We receive payments from customers based upon billing cycles. Invoice payment terms usually range from 30 to 90 days.

Accounts receivable are recorded when the right to consideration becomes unconditional.

Contract assets include amounts related to our contractual right to consideration for performance obligations not yet billed and are included in prepaid and other current assets in the condensed consolidated balance sheets. The amounts were immaterial as of June 30, 2026 and December 31, 2025.
Deferred revenue primarily consists of amounts that have been invoiced but not yet been recognized as revenue and consists of performance obligations pertaining to support and subscription services. We recognized revenue of $28.5 million and $26.4 million during the three months ended June 30, 2026 and 2025, respectively, and we recognized revenue of $52.7 million and $47.0 million during the six months ended June 30, 2026 and 2025, respectively, related to deferred revenues at the beginning of the respective periods.
Deferred Contract Acquisition Costs

We capitalize certain contract acquisition costs consisting of incremental sales commissions incurred to obtain customer contracts. Deferred commissions related to product revenues are recognized upon transfer of control to customers. Deferred commissions related to services revenue are recognized as the related performance obligations are met. Deferred commissions that will be recognized during the succeeding 12-month period are recorded as prepaid expenses and other current assets, and the remaining portion is recorded as other non-current assets. Amortization of deferred commissions is included in sales and marketing expense.

As of June 30, 2026, the current and non-current portions of deferred contract acquisition costs were $8.8 million and $5.3 million, respectively. As of December 31, 2025, the current and non-current portions of deferred contract acquisition costs were $8.3 million and $5.7 million, respectively. Related amortization expense was $1.9 million and $1.8 million for the three months ended June 30, 2026 and 2025, respectively, and was $3.9 million and $3.2 million for the six months ended June 30, 2026 and 2025, respectively.

We had no impairment loss in relation to the costs capitalized and no asset impairment charges related to contract assets during the three and six months ended June 30, 2026 and 2025.

Remaining Performance Obligations
Remaining performance obligations represent contracted revenues that are non-cancellable and have not yet been recognized due to unsatisfied or partially satisfied performance obligations, which include deferred revenues and amounts that will be invoiced and recognized as revenues in future periods.
