Build a Customers database with a shopping cart

[stock_picks]

I have two "Members Only" kind of websites where customers pay a monthly subscription in order to get access to stock market information. I plan to launch new products next year, not necessarily subscription based, it can be DVDs or books.

Anyway, I'm looking for a solution that would allow me to create order forms, collect payments (a 1-click shopping cart that would integrate with Authorize.net), track campaign results, and manage the customers database. Does anyone know an existing company that offers a service like that?

My goal is to be able to create and modify order forms to cross sell easily. Also, I'd like to be able to track the results and make changes to the sales copy. And collect all the customers data into a single database.

My question is more about building a marketing database. Most shopping cart solutions would help you build a "transactions database", but I need to build a "customers database" too. This database will have contact info for all customers, wich products they have bought, how long they stayed as a subscriber, how many promo emails they received, etc.

Initially I was looking for a shopping cart that would have this CRM functionality. But if that's not possible, then I would settle for 2 separate solutions that can be integrated.

Which solutions do you recommend?

I suggest... get a good team (hint hint) to make you a customized solution integrating cart and crm

or if you can code yourself you can do this with php.

Sure you can do that. You can also do it in perl, asp, or any other server-side language. You can also expose your website and every other site on the hosting machine to injection attacks, virus attacks, or spam abuse because you're not aware of the security issues and how to program against them, you've taken a straight-line approach to completing your task.

Unless you're good at programming or have a year or two to learn the language, test your apps, test the usability of your interfaces, test for security vulnerabilities, scrap it all and start over learning from your mistakes, "suggestion A" is probably the wisest choice with someone who's experience you can trust.

Another and probably most used option is to purchase licenses for existing packages, but even those can suffer the same security issues, for which the liabilities are completely yours and usually waived in the license agreement.

Last is the free dogpile, everyone wants everything for free but wants to make money. I've seen a lot of these free applications and they are worrisome, if the stats on these sites are true (This "really bad app with tons of security vulerabilities" has been downloaded 1,200,000 times) then there are a lot of sites out there ripe for the picking.

But to be fair, there are probably millions of free solutions that are working fine without being hacked. It just means the bad boys and girls haven't found them yet. :-)
