 So we got the chart of accounts, enable account numbers. Now, account numbers can be great, but people often mess them up because they don't know how to add account numbers in a way that makes sense. So they get all tied up with account numbers. So by default, they turn the account numbers off, which is what we're going to do here. I think we're going to have a section that just shows you the general items of account numbers. We possibly have that or a course on that. So if you want to learn the account numbers, you can. But by default, we're going to be putting them off here. And the thing with account numbers, they give you a little bit more control about the orderings of your accounts and less flipping of accounts, changing the order year over year, because it's going to, in what not, because as the, as you add accounts and whatnot. So, so, but if you don't add the account numbers properly, the account numbers will actually be not making sense. They'll be out of order in essence because the, the chart of accounts is first in order by account type balance sheet accounts, then income statement accounts. The account numbers need to line up with that and that's how they have to be added. So we'll talk more. I think we have a section on that and it says tips, tips account and then billable expense account. So this account that, that goes with the settings, expense, bills, expense, track billable expenses and items as income in a single account. So we're going to keep that off by the default here. So I'm going to keep that. Okay. Next one, we're going to say categories and just, let me just recap this again. If you, that tips we saw setting before, this is the account that goes with the setting sales form contact. So if you set that up, then you need the account that's going to basically be set up with it here and that's what they're basically saying.
