Anyone would think such "labor saving using IT", nowadays.
A Web site which is totally automated by connecting a 'Web form' and a 'Payment system' can be created easily, If limited to a particular method of payment to "PayPal" or "Google Wallet".
However in fact, for an event of about 50 or 100 people, you would like to correspond on the phone and by e-mail. Why?
In short, it is because there will be various demands (exceptions) such as "invoicing for corporation name" or "Cash payment of day of the event". If humans response, they could handle anything flexibly. (Though mistakes would occur, of course ...)
The Business process below is a Workflow that humans make the payment confirmation operations.
Taking over the participation application data received in the Google Spreadsheet, humans do the subsequent processing. Specifically speaking, humans confirm the settlement completion by "Invoicing + Bank Transfer" or "PayPal Credit Card" or "Handing Cash on the Day".
Excellent point of it is that an "Invoice PDF" will be sent automatically when the participation applicant designate "invoicing + bank transfer".
