Electronic invoicing is used for transmitting payment information from a business to a buyer. The information is structured in a standard format so that the electronic invoicing system of the seller and buyer can recognize and share the information.
E-invoicing takes the place of traditional paper invoicing, which is slower and requires more time and effort to match the invoice to the appropriate order and then pay the amount due.
There are a few different types of electronic invoices you should know about. Each of them is structured differently but are readable by most invoicing systems.

| Credit memo/invoice | Sending discounts or refunds |
| Debit memo/invoice | Requesting a larger amount of money from the customer (commonly sent after completion of a project that had an estimate) |

| Recurring invoice | Requesting payment for services that repeat at regular intervals |
| Interim/progress invoice | Requesting partial payments during large or long-term projects based on predetermined milestones |

Now that you know what kinds of electronic invoices there are, let’s take a look at how you make and send an electronic invoice.

4. Add payment details so the customer knows how and when you want to receive payment

Now that you know how to create and implement an electronic invoice, let’s look at the options for e-invoicing systems.
When you’re looking for an e-invoicing system, five of the most important factors to consider are:
The most common e-invoicing systems are found within accounting software, either as a native component or as an integration. Because accounting software is designed to make tracking and managing your business’s finances easier, invoicing is an important feature of these systems. Within your accounting software, you should be able to create invoices in conjunction with orders. Creating an electronic invoice within the system should also accurately update accounts receivable.
If your business isn’t big enough to need dedicated accounting software at the moment, online invoicing generators can save you some money. Unfortunately, many don’t allow you to connect them to your spreadsheets or orders, so you’ll need to input the information manually.

The benefits of e-invoicing are so big that they might convince you to stop creating manual invoices altogether.
However, there are some disadvantages of electronic invoicing that you need to be aware of before you start using them.
While the downsides of e-invoicing are usually outweighed by the benefits, it’s important to understand where you might run into problems.
