Mega PDF Invoices

Initially installed this app without knowing it had a default setting which automatically started sending invoices out to hundreds of my customers without even letting me finish customising the invoice. This made my business looking rather silly and unprofessional.
However this initial hiccup has been rectified and as a result, the team at Mega PDF have implemented a few changes so this will not happen again. Now the app once installed needs to activate manually to get the invoices rolling. Well done guys!
I have now re-installed the app. and all is working well.
Mega PDF has worked patiently with me to custom design an invoice. Only when I was happy with the invoice layout did I activate the app to start sending them out. I found the team very helpful to work with.
This app does exactly what I want it to do which is send out tax invoices via email to my customers on receipt of payment. I am pleased to say I give this app and the team 5 stars.
