Accounting issues and business organization

Yes.

No.

This is a hugely complicated and individual and location-specific question which can be answered for you only by a qualified professional in your jurisdiction, and that's who you should be asking. Nobody here can possibly answer it helpfully for you, when you don't even say which country you live in, let alone anything about your personal tax-position (and this isn't the place to do that), and so on.

Are you looking something like this? as TALLY. it is an accounting software. you can take a look on it.

Ditto what Alexa said and with the usual disclaimer that I can't give individual legal advice on a forum and I can only make generic statements:

IMHO, it is always a good idea to incorporate.

Online liability absolutely exists, whether its from inadvertent copyright infringement, republishing a defamatory statement or any other "gotcha". A corporation *may* provide you a legal shield.

In addition, when it comes time to sell your online property such as one website, it is far better to sell it as an asset of your corporation to someone else. That way too, if the buyer decides to sue you for whatever reason, the suit is still against your corporation.

Of course, to have any real protection from the corporation you need to follow all the proper statutory requirements, avoid commingling funds etc otherwise the corporation becomes useless from a liability perspective.

Finally, having a corporation and properly maintaining its books will let you enjoy tremendous tax benefits.

For the small cost of incorporation (in the US), it is my preferred approach. And you only need one corporation and then you treat each online venture as a distinct asset in the portfolio of this corporation.

Regarding software, I don't see much difference from an accounting perspective that would obviate using something like Quickbooks, that allows you to set up your own chart of accounts to tailor it to your business. There are some sales tax issues to take into account (potentially) and generally you'd need to look at whether you're using an accrual basis or cash basis, but if you can run your books for a brick-and-mortar, you can do so for an online biz.
