Also if you are going to use 3rd party addons then you need to trust the developer.
1) How long have they being trading.
2) Are addons their main business.
3) How many addons have they developed.
4) Have they any reviews on specific forums (ie. WHMCS addons- have they any reviews on the WHMCS forum)
