Hi Lambilia , a lot of the reasoning behind the change has been outlined in my post and subsequent replies under the main thread here
But to give it another go here, one of the outcomes this change hopes to achieve is to help reduce invoice fraud in Australia.
By ensuring that only a verified business can utilise the MYOB platform for distributing invoices, we are taking steps to help reduce invoice fraud for the end consumer.
Additional features like secure payments then provide added security for our customers when receiving payments while also helping get paid faster and save time reconciling.
The payments feature can absolutely be disabled after the upgrade if it is not wanted however.
