Hello, fellow warriors!

I'm trying to build a website offering an article writing service.

Let's say someone visits my website, buys ten articles of 500 words each, and is then forwarded to a thank you page. There, they would fill in a form, to make specific requests about their order (for example: "I want the articles to be about dog training").

Is there a program that allows to have that message saved somewhere online (some back office), so that a team can collaborate on that order?

I'm not looking for a contact form that just emails the message to me. Email can be unreliable and messages end up in spam sometimes.

What system do the service websites use?

I know support desk software can do this, but I was wondering if there's another (better?) way to do this.

Thanks!
