Online invoicing lets businesses email invoices with built-in payment options directly to customers. Compared with paper invoices or emailed PDFs, online invoices are easier to track and help companies get paid more quickly. While you’ll need to get set up with software that supports online invoicing, switching to a digital solution is usually easy. Here’s what you need to know about online invoicing.

🤓Nerdy Tip

Online invoicing is sometimes referred to as digital or electronic invoicing.

How does online invoicing work?

Online invoicing is a similar process to paper invoicing in that you send customers the same information but in a digital format.

You can use online invoicing software, such as Zoho, Hiveage or Invoice Ninja, to select a template and add the billing information. Once you generate the invoice, the software notifies the customer by email. The customer can view the invoice immediately and pay digitally on the spot if you've enabled online payments.

Online invoicing also streamlines aspects of the billing process for you. Some systems track invoices and can tell you when a customer has viewed an invoice and even send reminders when the due date gets close. You can also sort paid and unpaid invoices. Plus, many invoicing systems allow you to set up recurring billing, so you don’t have to worry about initiating new invoices for repeating services.

Invoicing is often a common feature of popular accounting software services, such as FreshBooks and Wave, as well as an additional feature of payment processing and point-of-sale options, like Square.

Pros of online invoicing

Online invoicing creates a number of benefits for small businesses, including:

  • Immediate customer receipt. Customers receive online invoices immediately and can pay just as quickly, cutting out the delivery time of nondigital methods.

  • Faster payments. Adding a link in an invoice to pay it online is not only convenient for customers, but also good for your business’s cash flow.

  • Streamlined accounting records. Many software options for online invoicing integrate with accounting programs and consolidate record-keeping into one location.

  • Saved time. You’ll spend less time tracking which invoices are paid, prepping new ones and mailing them to customers.

Cons of online invoicing

There are a few disadvantages to using online invoicing, which include:

  • Some invoicing software or features require a monthly fee. Not all options are free and might require a small investment on your part, depending on which one you choose.

  • Spam filters can hide invoices. Sending invoices by email means a customer’s inbox could tag them as spam, so you might still have to call a few customers who are unaware they have an invoice waiting.

  • Email can be hacked. Privacy might be compromised if a customer’s email is hacked, which is much less likely if an invoice is mailed.

  • Some customers might not like digital formats. You’re likely to have at least a few customers who aren’t tech savvy and want good old-fashioned paper invoices.
