Contract Balances

We receive payments from customers based on a billing schedule as established in our customer contracts. Accounts receivable are recorded when we contractually have the right to consideration. In some arrangements, a right to consideration for our performance under the customer contract may occur before invoicing to the customer, resulting in an unbilled accounts receivable. The amount of unbilled accounts receivable included within accounts receivable, net on the condensed consolidated balance sheets was $8.5 million and $7.2 million as of July 31, 2019 and January 31, 2019, respectively.

Contract liabilities consist of deferred revenue. Revenue is deferred when we have the right to invoice in advance of performance under a customer contract. The current portion of deferred revenue balances are recognized over the next 12 months. The amount of revenue recognized during the three months ended July 31, 2019 and 2018 that was included in deferred revenue at the beginning of each period was $64.6 million and $30.6 million, respectively, and $90.7 million and $38.9 million during the six months ended July 31, 2019 and 2018, respectively.

Remaining Performance Obligation

The terms of our subscription agreements are monthly, annual, and multi-year, and we may bill for the full term in advance or on an annual or monthly basis, depending on the customer preference. As of July 31, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations was $457.6 million, which consists of both billed consideration in the amount of $181.4 million and unbilled consideration in the amount of $276.2 million that we expect to recognize as revenue. We expect to recognize 62% of our remaining performance obligations as revenue over the next 12 months, and the remainder thereafter.
