Revenue from Contract with Customer [Abstract]  
Revenue and Performance Obligations Revenue and Performance Obligations

Subscription revenue is recognized over time and accounted for approximately 94% and 95% of our revenue for the three months ended April 30, 2019 and 2018.
    
The typical subscription term is one to three years. Most of our subscription contracts are noncancelable over the contractual term. Customers typically have the right to terminate their contracts for cause, if we fail to perform. As of April 30, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations was $574.0 million, which consists of both billed and unbilled consideration that we expect to recognize as subscription revenue. We expect to recognize 53% of the transaction price in the twelve months following April 30, 2019, in our consolidated statement of operations and comprehensive loss with the remainder recognized thereafter.

We elected to apply the practical expedient to not disclose the transaction price allocated to remaining performance obligations for contracts with a contract term of one year or less. In addition, we do not disclose the transaction price related to revenue from professional services, training services and web revenue as revenue from these sources is recognized within one year.
Contract Balances

Contract assets represent amounts for which we have recognized revenue, pursuant to our revenue recognition policy, for contracts that have not yet been invoiced to our customers where there is a remaining performance obligation, typically for multi-year arrangements. Total contract assets were $14.6 million and $11.9 million as of April 30, 2019 and January 31, 2019, of which $1.3 million was noncurrent and included within "Other assets—noncurrent" on our consolidated balance sheets as of both periods. The change in contract assets reflects the difference in timing between our satisfaction of remaining performance obligations and our contractual right to bill our customers.

Contract liabilities consist of deferred revenue and include payments received in advance of performance under the contract. Such amounts are generally recognized as revenue over the contractual period. For the three months ended April 30, 2019 and 2018, we recognized revenue of $157.0 million and $112.0 million that was included in the corresponding contract liability balance at the beginning of the periods presented.

We receive payments from customers based upon contractual billing schedules. We record accounts receivable when the right to consideration becomes unconditional. Payment terms on invoiced amounts are typically 30 days.
