 We used to have the cycles that would have centers in them. So on the customers, you have the customer center. And then on the vendor, you have the vendor center. And then on the payroll, you had the employee's center. So we have similar concepts over here. So if you try to group that in your mind, you're like, how am I going to figure out all these things on the left-hand side? Well, if you think, well, I could think about it this way by cycle, right? I have the revenue cycle or customer cycle, the vendor cycle, the employee's cycle. So those I can think of as centers on the left-hand side. So the sales center is kind of like the revenue cycle or customer cycle. So if I go into the sales center, you can see I have the overview and all the stuff in it here. But if I just click on it, then all those options are up top in the tabs. So now you've got the overview. We've got the all sales. These are the transactions that happen for the sales side. We've got invoices. These are the things that we, when we build the client, the major tool that we're going to be using, we can create invoices from here as well as from here. So we can create invoices from multiple places. If I'm in the customer center or sales center, estimates, which are going to be tracking if we have an estimate for a job before we actually invoice the job. We have our customers. So this is us tracking the people that we do business with that are going to hopefully pay us. So of course, if we have accounts payable that we're tracking, we do the work, we send out invoices. They haven't paid us yet. Then this is going to be a very important area so that we can try to track who owes us the money. And then we've got the products and services. These are the things that we use to populate the invoices such as the things we do, the things that we sell, goods and services. And then on the expenses side, we have the expenses over here. This is going to be the expense center. Same thing if you hit the dropdown, this is kind of like where the vendor side of things is. So a lot of these forms could be found also in the expense center. If I look at the expenses tab, this is going to be the transactions. We can sort the transactions here. We'll get into this later with relation to the expenses or ultimately money going out. Bills represent things that we have entered a bill for but have not yet paid for. The vendors, for our purposes, vendors means people that we are going to be paying for. Right? You might think vendors is a confusing term because we might think of ourselves as a vendor because we sell stuff and we are a vendor if we sell stuff. But for QuickBooks, you got to remember which side of the table you are on. When QuickBooks says customers, we mean our customers, which is for me a little bit easier to click in my mind. When I hear vendor, I kind of like I'm a vendor. It's like I'm also a customer because I buy stuff from other people. But when I'm looking at QuickBooks, these terms could be used in common language on either side of the table. But for QuickBooks, you got to know which side of the table they are talking about. If the vendors are the people that we buy stuff from, money is going out ultimately. And so then we have the people that we are buying stuff from down here, the list, and then the contractors. And then the mileage, if we are tracking mileage, possibly for tax purposes, that's kind of a special area. We might have a little section on that to get in more detail if you want to. And then you have the employees. So that cycle is over here in the payroll. So the payroll cycle. So remember that we'll talk about payroll a little bit more later, but payroll is a special area in and of itself and you have a primary question being, do you want to do payroll within QuickBooks or do you want to do payroll outside of QuickBooks using a third-party provider like an ADP or a Paychex? So that's a big question that you want to make sure you think about if you have to deal with payroll because it's a pain to change payroll. You'd like to get it done correctly the first time if possible. Contractors, you have a question as to whether someone is a contractor or an employee with contractors. We have to deal with getting their information possibly to send out, in the United States, to send out 1099 forms and then workers comp again an issue which is related to the payroll. So those are the primary centers here. Now the other big center that you'll be dealing with all the time is going to be the banking information, cash, the cash flowing in and out. So that's going to be in your transactions over here. Note that most people, when you use QuickBooks, you might probably want to connect to the bank feeds and we will do that. We'll talk about connecting to the bank feeds, but the first practice problem we work through, we're going to do it without connecting to the bank feeds so that you can see the cycle of the process because when you connect to the bank feeds, it's kind of advertised and people often feel like everything's going to be automated really easily to connect to the bank feeds. In some companies it is really easy, but other companies it's not as easy and once you connect to the bank feed, all of this information is going to pull in here to what I call bank feed limbo and you're going to have to know what to do to pull it from here into your financial statements. How do you know what to do to pull it from here into the financial statements? You have to understand the normal accounting cycle and how the bank feeds fit in it. So that's why the first part of the course, we're going to just do normal accounting without the bank feed, the whole process, and then we'll think about how the bank feeds can fit in depending on the type of business that we have. But for many companies, obviously, this would be another common area that we would be working in a lot of the times. We'd be in the transactions. These are the bank transactions. Here's the different accounts that you could have connected, checking accounts, savings accounts, credit card accounts or the common transactions. We also have app transactions. We might have a special course that looks at or special part or special section that looks at this in a little bit more detail. If you use Shopify or eBay or Amazon, then you have some options in terms of how you're going to get the information pulled in from those online resources. And they have these resources here for that, which is nice. And you've got these app transactions, which is a specialized area for those types of things. And then your receipts. You can upload your receipts here and possibly attach receipts, for example, to certain forms, which can help you with your audit trail. And then your reconcile information is here.
