When we used to use Photo One, there was an option, when creating the invoice, for us to say what we wanted the Invoice Terms to be at the time of printing the invoice. That way if they are placing an initial order, we can have a certain set of terms and then when they are picking up a finished order, we can change those terms to say something different like "Picked up all" with a place for them to sign and date.
Now that we use MyStratus, the Invoice Terms are tied to the appointment type and we cannot change them at will, which is kind of frustrating, because now we have to take the time to hand write things we used to be able to just select from a drop-down menu.
