I would ask all users be aware that currently if you bill an item to a client that has a reminder attached to it and that reminder autocompletes another reminder on the patients file - if you later delete that item (eg you billed the wrong type of vaccination ) while the newly created reminder will also be rolled back the existing reminder will remain complete (even though it actually wasnt completed)  You system will NOT send reminders for that particular event as it believes you have done it.

Do not check prices in a uncompleted invoice under any patient, as it negate and reminders you have set.  This applies to all reminder types that are grouped as well.

EG the pet has a reminder for Tick control due in 4 weeks and you check the price of Bravecto - the client decides its too expensive to buy just then and says they will sort it when they get the reminder in a few weeks....the reminder will have been marked as complete by the price check.  on the uncompleted invoice.
