Hey there Antbrew 👋 Fantastic idea!
We always love hearing from our Solmates and the new ideas they bring to make Solo the very best it can be! While I don't have any concrete details on customised invoice reminders for now, it looks like someone has had the same train of thought over on our Ideas Board: Customisable payment reminders | MYOB Community
Our teams pay close attention to the thoughts and ideas expressed on the Forum, so if an idea has many comments or upvotes, the closer it becomes to landing on their radar 🚀
