Before you start creating product and service records, you should establish your preferences.
You can always view the Products and Services screen by clicking on Sales in the toolbar, then Products and Services. (You can also access it by clicking on the gear icon, then Products and services under Lists.) This comprehensive table, a kind of dashboard for your products and services, displays real-time information about each item's pricing and inventory levels, as well as its type and tax status.
Click the down arrow in the Action column, and you can work with that product in a variety of ways. For example, you can run a report, adjust its starting value and quantity, and reorder. You can also edit the record from here. Large, colorful buttons at the top of the screen give you an instant view of the number of items that are low on stock or out of stock. Click on one, and a list of those items will appear.
Warning: Be sure you understand your reason for modifying inventory level numbers (either their starting value or quantity) and the impact this could have on your reporting. We recommend that you consult with us before taking either action. The same goes for reordering if you haven't worked with purchase orders in QuickBooks Online before.
Using Your Records
Once you start creating transactions like invoices and sales receipts, you'll see why we recommended that you complete all of the relevant fields in your product and service records. QuickBooks Online is good about allowing you to supply data "on the fly" (as you go along), but your daily work will go much faster if you do your setup work first.
Here's how you add a product or service to an invoice or a sales receipt, for example. Click on the +New button at the top of the screen and select your transaction type. Choose the appropriate Customer by clicking on the down arrow in the first field in the upper left. Check the rest of the fields in the top half of the form and make any necessary changes. Click in the field under Service Date, then click on the small graphical calendar to select the date of the sale. Click on the down arrow in the field below Product/Service.
