Revenue from Contract with Customer [Abstract]  
Revenue from Contracts with Customers Revenue from Contracts with Customers
The Company generates all of its revenue from contracts with customers. Many of the Company’s contracts with customers contain multiple performance obligations. For these contracts, the Company accounts for individual performance obligations separately if they are distinct. The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis. Standalone selling prices of software licenses are typically estimated using the residual approach. Standalone selling prices of services are typically estimated based on observable transactions when these services are sold on a standalone basis. The Company usually expects payment within 30 to 90 days from the invoice date (fulfillment of performance obligations or per contract terms). None of the Company’s contracts as of June 30, 2020 contained a significant financing component. Differences between the amount of revenue recognized and the amount invoiced are recognized as deferred revenue.

Practical Expedients
The Company generally expenses sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within sales and marketing expenses.
The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which revenue is recognized at the amount to which the Company has the right to invoice for services performed.
