Invoices are a core part of any business. To receive payment, many companies send invoices and bills, ranging from roofing services to healthcare. Initially, invoices were entirely paper-based. The advent of electronic invoicing (or e-invoicing) in recent years has revolutionized how invoices are managed, bringing workflows to a new level and simplifying the entire process.
Approximately $8.74 billion was generated by e-invoicing in 2021, with $29.68 billion by 2027 expected. While the trend toward e-invoices is on the rise, over a third of accounts payable departments still receive paper invoices, despite facing the paper invoice error costing $53.50. The road ahead remains long.

E-Invoicing (Meaning, Pros & Cons, and Legal Requirements)
E-invoices are invoices that are electronically delivered and in a standardized electronic format sent from one service provider to the client. The use of electronic invoicing systems comes with numerous advantages to both businesses and clients.

Legal requirements for e-invoicing
According to a Federal Ministry of Finance ruling on 1 July 2011, electronic invoices are just as valid as paper. Email-based electronic invoicing no longer require signatures and can be sent via email.
Compliance Requirements

Types of e-Invoicing
Electronic invoicing is becoming more prevalent in many countries. Even though e-invoicing is not legally required in some countries, it is nevertheless carried out since it promotes smooth electronic invoicing and payment efficiency. Thus, it can be divided into two invoice types: those that do not comply with laws and those that do.
e-Invoicing without compliance
This is where the buyer and supplier, i.e., the parties involved in the transaction, decide the details and format of the invoice document. The buyer and supplier agree only to the format of the data to be sent and do not comply with the electronic invoicing regulations of the country in question.
Key characteristics:
- Invoices include structured data using either EDI (Electronic Data Interchange) or simple forms hosted on the web
- Electronic invoice is created and sent either through the e-invoicing solution of the supplier or via a web-based form
- Payment systems receive electronic invoices in a format that can be processed immediately by their accounts payable systems
e-Invoicing with compliance
E-invoicing rules and regulations vary from country to country. Compliant e-invoices follow the same process with these key differences:
- Regulations and legislation of the trading parties determine the invoice format
- Electronic invoicing adheres to government guidelines regarding content validation and security
- Invoices can be used for auditing and VAT (value-added tax) calculations

How Does e-Invoicing Work?
e-invoicing is another name for electronic invoicing. Essentially, it involves sending invoices electronically or over the Internet rather than via email address or in person. e-invoicing is different from digitizing scanned paper invoices.
What Doesn't Qualify as E-Invoicing
Photocopies of scanned paper invoices sent via fax machines, and apps that convert them to PDF or word formats invoices aren't considered e-invoicing. Invoices not issued electronically and do not contain structured data readable by machines are not considered e-invoices.
Since the early days of the XML file format and the inception of Electronic Data Interchange EDI - machines for material procurement and document processing, e-invoicing has been around. In the modern age of digital invoices, creating them using billing software solutions like InvoiceOwl is often possible, enabling customers to access their invoice data remotely through email or online in a secure environment. There are a lot of invoicing systems out there that allow customers to pay through their portals as well.
Like with paper invoices, you will also need to include a lot of information on your electronic invoice, including information about the trading partners i.e., buyer and seller, the amount due, the date of payment, and the invoice number, just like with paper invoices.

e-Invoicing vs. Manual Invoicing
E-Invoicing vs Manual Invoicing Comparison
| Feature | E-Invoicing | Manual Invoicing |
|---|---|---|
| Pre-filled invoices | Customize templates once; information appears automatically on all future invoices | Manually enter sales and business information for each invoice |
| Follow-ups | Configure automated payment reminders sent at intervals you set | Manually follow up with customers to ensure payment |
| Real-time reports | Access invoices in real-time; make predictions and decisions instantly | Manually retrieve and collate data from previous invoices using spreadsheets |
| Online payments | Accept online payments through integrated payment gateways | No direct integration; must attach bank account details or accept cash |
Invoices pre-filled
Invoicing clients manually requires you to enter sales and business information manually. The invoice amount can be calculated, discounted, taxed, and your logo uploaded. If you choose to use e-invoicing, you can customise the invoice templates as per your needs and specifications. You will only need to upload information that will appear on all of your future invoices, such as your business' logo, name, address, and contact information, once. This will result in the automated generation of them on all future invoices. So, welcome the new automated business rules and say bye to the old manual techniques.
No more manual follow-ups
With manual processing, you will have to follow up manually with your customers to ensure they pay their invoices. When you use e-invoicing, you can configure payment reminders, which will be automatically sent to your customers at intervals configured by you, informing them when their payment is due.
Creating real-time reports
In the manual processing, you will be required to manually retrieve and collate data from previous invoices and create reports. As a result, using spreadsheets or word processor records to show the results. With e-invoicing, you can access your invoices in real-time, making predictions and decisions based on the data without waiting. Electronic invoicing software, like InvoiceOwl, one of the most common reports available is the one on payments received, bad debts, and outstanding invoices to help you make business decisions that will benefit your business in the long run.
Accepting online payments is simple
There is no direct integration between third-party applications and manual invoicing business systems. The invoice must be attached with the bank account details of your business, or payment must be made in cash. It is possible to accept online payments when using e-invoicing through a payment gateway easily when you use e-invoicing. The manual payment methods can be time consuming whereas accepting online payment is quick and accurate.
