QuickBooks is a great resources for keeping track of your business's bookkeeping needs. At Intuit, we know each business has different management tools they're looking for, which is why there are three versions of QuickBooks to choose from: Self-Employed, Online, and Desktop. I'll go over the options to make sure you have the best fit for you.
QuickBooks Self-Employed is the simplest version of the QuickBooks program. With it, you can enter expense and invoices transactions while keeping track of your sales tax and mileage. When you create transactions in this version of the program, you add the name of the customer or vendor directly to the transaction, rather than creating a profile for them.
There are a couple options for entering expense transaction you've already paid in your books. You can enter the transactions manually by going to the Transactions section and clicking Add transaction or by connecting a bank or credit card account to QuickBooks Self-Employed. When you work through these transactions, you can add the vendor names as needed.
When you have a situation where you'd like a bit more structure, such as having the ability to add a vendor profile with opening balances, it's best to consider QuickBooks Online or QuickBooks Desktop. The QuickBooks Online option is a similar platform to Self-Employed, and includes more fleshed out features to give you more control over managing your books.
I'll leave you with this link that goes over all QuickBooks products so you can see what's best for you. There isn't yet a way to transfer information from QuickBooks Self-Employed to the other versions of the program, so starting with Online or Desktop would mean starting fresh. As I mentioned, though, you'll be able to take advantage of options such as entering opening balances, which could help expedite your setup.
