Is it possible to show the installment table on the invoice pdf when using installment terms?

May be able to follow something like SA: 84302

I found that one as well, but I can’t figure out a way to utilize the info to do what I want, short of creating a ton of custom fields to store the information (I need installment number, date, amount, amount due, status)

Have you considered a custom data source pdf? You could hide the native button and give them another button that does the same thing but you control it a lot easier.

I can give that idea a try… I don’t understand why this is so difficult. I feel like it should just be an option

I've run across this several times lately where the data just isn't available as is and have had to do the custom data sourcing. You can certain get all of the data into fields and parse as well but its a matter of which one do you want to maintain.
