Contract liabilities consist of cash payments received (or unconditional rights to receive cash) in advance of fulfilling performance obligations. As of June 30, 2021, the Company did not have a contract assets balance.

The following table is a summary of the Company’s opening and closing balances of contract liabilities related to contracts with customers.

(Amounts in thousands)	Total
Balance at December 31, 2020	$	864
Additions through advance billings to or payments from vendors		768
Additions through business acquisition		3,315

The increase in contract liabilities during the six months ended June 30, 2021 was primarily due to invoiced amounts that did not yet meet the revenue recognition criteria, partially offset by the revenue recognition criteria being met for previously deferred revenue.
