A large company in Australia, called Alex Ltd, supplied $22,000 (GST Inclusive) worth of products to one of its local customers, Beta Pty Ltd, on 1 August 2019. Beta paid this bill in two equal instalments of $11,000 on 10 May 2020 and the second instalment on 15 September 2020.

Discuss how each entity should account for GST. Alex Ltd is a GST-registered entity with ATO and accounts for GST on accrual basis, files BAS monthly and remains registered, while Beta is not registered for GST at all in both years.
