This company is a complete waste of web space never do business with this company if you care about yourself and your client and you don't want to waste time, money or get headaches. I had to fix errors in their script that they made up excuses about. Paid them to fix other errors in other scripts and they fixed it improperly every time so I had to move on to another company.
If you are okay with wasting money then do business with them but take my advice don't let them fool you. They are some of the worst programmers I've come in contact with. I wish I had listen to the many horror reviews out their it would save me a lot of money.
I had other problems similar to the page this guy wrote: http://www.truth-or-consequences.com/badder_business_bureau/stivasoft/stivasoft_sucks.html
In my opinion they are a scam they sell you a broken script and then charge you to fix it. In all my reviews I've never had to give a 1 star rating I always try to see the best in a company but I can't see myself giving them a 2 star rating. I wish their was a half star rating or a no star rating that would better suit this company.
On their site they claim to be a huge company but in fact they are not a huge company they are a small fry in a big basket. After this experience I've decided since I already have most of the knowledge necessary to write php or JavaScript applications I will start up my own software store and sell legitimate scripts.
