Turnover is measured at the fair value of the consideration received or receivable, net of discounts and value added taxes. Turnover includes revenue earned from the sale of professional services and software subscriptions.
Supply of professional services
Turnover from the supply of professional services is recognised by the sales, which are invoiced monthly, to charge clients with the actual amount of billable time costs incurred by staff in that month.
Turnover from sales of software subscriptions is recognised as earned when each accounting month completes. These monthly amounts are calculated as a proportion of the total number of months' subscription that comprises each sale. Amounts not yet earned at any accounting period end are shown as Deferred Income liability in the balance sheet.
