Invoicing with GnuCash
I get a lot of businesses asking me about running their businesses with open source software. Many assume there are not packages that Linux and open source has no offerings for the SMB (or the consultant) needing a tool to keep track of clients, vendors, and (especially) invoicing. And even though many users know of GnuCash, few know of it's wealth of tools.
One of those tools available with GnuCash is invoicing. With GnuCash you can create a professional invoice that will also automatically post to your accounts receivable. So not only are you able to issue invoices, the creation of these invoices will help you keep track of money owed to you and your company. Let's see how this is done.
First things first
I will be working with GnuCash 2.2.9 on a Ubuntu desktop machine. I will assume you already have GnuCash set up properly for your business and that you know how to properly track finances with this tool. Before you start creating invoices, you will have to have customers created to bill. Â Let's create a new customer. To do this open up GnuCash and go the Business > Customer > New Customer menu entry to open the New Customer editor (see Figure 1).
You will want to fill out as much information for this customer as possible. If you do not give the customer a Customer Number, GnuCash will automatically fill one in for you. Make sure you fill out both Billing and Shipping addresses for this customer.
When you are finished filling out this information, click OK to save the customer.
Now you are ready to create an invoice. Go to the Business > Customer > New Invoice entry to open up the Invoice creator (see Figure 2). Â To associate a customer to this invoice click the Select button and do a search for your customer. If you have a lot of customers, you will appreciate the well planned search filters here. After you have your customer associated to the invoice. If you have a Purchase Order number or another means of identifying this customer account, you can add it to the Billing ID section. If you want to add Billing Terms for this invoice you will need to create Terms in the Billing Terms Editor (you can find this tool in Business > Billing Terms Editor.
When you have filled out all of the information, click OK to create the invoice. The invoice will appear in the GnuCash main window, ready to add items.
In Figure 3 I have added a single item to the invoice (a mixer).Make sure you enter all of the details (such as the correct Income Account). Of course you can add as many items to this invoice as you need. Pay close attention to service items as they may not be taxable items.
Posting and Printing
You can not print the invoice, until you post the invoice. When you post an invoice it moves the transactions to accounts receivable. To post the invoice click the Post button. If your window is too small (as shown in Figure 3), you will have to click the drop-down arrow to reveal the Post button. When
you Post an invoice you can select a Post date. If you have added terms to the invoice the Due Date (see Figure 4) will reflect these terms. NOTE: If you have multiple items in an invoice, and you want them all to be recordedÂ separatelyÂ in your asset account, uncheck the "Accumulate Splits" box.
If you have not created an account to post to, you will need to click the New button now.
Once you have posted the invoice you can hit <Ctrl>P to print the invoice. A printed invoice will appear like the example in Figure 5.
GnuCash is a much more versatile application than most assume. Not only can you keep track of your personal finances, GnuCash easily can tackle the task of your small business or consulting finances. Give it a go and see how far you can push this fine open source application.Advertisement
