[NSFW] refund amout not display in invoice pdf

Hello @dilipom13,

We follow GAAP (Generally Accepted Accounting Principles) which means that administrative changes should be documented separately. This means that an original invoice should never be modified by a refund. In most countries (at least in the EU) this is even considered fraudulent (and illegal). We have chosen to follow this in both the free and the paid extension. Just only the paid Professional extension has the capability of generating credit notes for the refund.

More about creating Credit Notes can be found here:
Creating a refund / credit note

Let me know if you have more questions!
