When you use Fienta to sell tickets, the revenue is your own sales directly to your customers. Although the money moves through Fienta's bank account, it is still your sales with your VAT amount. Fienta just acts as a payment processor in this context.
You should register your sales the same way as you were selling tickets at the venue or if your event goers were making you direct payments. In accounting, the sales can be registered as one entry with reference to off-balance sheet report in Fienta or in Excel spreadsheet, downloaded from Fienta.
Payouts from Fienta
Payouts are made on a monthly basis - at the beginning of each month, for last month sales. From the payout, we deduct Fienta's service fee and ticket refunds, if there were any. We also send you an invoice for our fee, with terms marked as "paid".
Our payouts and service fee is calculated based on the actual cash inflow. However in bookkeeping, usually the accrual accounting is used. The two principles match in most cases, but sometimes the ticket purchase and actual payment are done in separate periods. For example, when the purchase is done by invoice issued in one month but paid in the next one.
