This is coercion! MYOB decides to remove a feature we are paying for when subscribing (sending invoices by email through MYOB), UNLESS we sign up to a payment service (financial service) we do not want. This has nothing to do with security. This is about forcing customers who signed up for an ACCOUNTING SOFWARE to accept FINANCIAL SERVICES (this why they need information about business owners, directors etc just like a bank would in order to comply with banking and anti-money laundering regulations).
MYOB need to give the option to opt out without loosing the ability to email invoices. All we want is an accounting software. Customers will go to XERO in droves.
