How does e-invoicing work in the UK? 

8 min read

As electronic invoicing mandates are spreading and more businesses go digital, many sellers are enjoying the benefits of using e-invoicing software for business.  

Whether you’ve already made the switch from paper invoices or are thinking about it, here’s a beginner’s guide to help you understand everything you need to know. 

What is e-invoicing, and what is an e-invoice? 

E-invoicing is a modern version of the traditional paper invoice. It’s a digital method of sending and receiving invoices, doing away with the need for physical documents. This process streamlines how businesses handle their invoicing, making it more efficient, saving you time, and also cutting down on paper usage. 

What’s an e-invoice? 

An e-invoice, also known as an electronic invoice, is a type of invoice that’s delivered electronically in a standardised format. The sending and receiving systems both use the same format, making it easy for them to exchange and understand the information. It’s a simple and efficient way to handle invoices without the hassle of paper-based processes. 

How are e-invoices different to paper invoices? 

Everything you’d find in a regular paper invoice – seller and buyer details, a rundown of the products or services, quantities, prices, and any taxes – is all present in an e-invoice.   

E-invoices come with structured data, using formats like EDI (Electronic Data Interchange) or XML (Extensible Markup Language). This makes it easy for computers to understand and handle the information.  

The use of e-invoicing is becoming increasingly popular as businesses recognise its efficiency, accuracy, and cost-saving benefits. 

What’s not considered an electronic invoice? 

Not everything digital is considered an electronic invoice. Simply sending a PDF of a paper invoice by email doesn’t quite cut it. Here are some examples that aren’t seen as an e-invoice: 

  • Unstructured invoice data issued in PDF or Word formats 
  • Paper invoices sent via fax machines 
  • Scanned paper invoices 

True e-invoices involve structured data, which means the information is in a format that computers can understand and process, making it easier to handle and analyse. So, if you’re just sending a picture of a bill in an email, you’re not quite in the electronic invoice territory yet. 

How does e-invoicing work? 

E-invoicing operates through electronic transmission, enabling businesses to automate their invoicing procedures. It involves the use of specialised software or platforms that facilitate the creation, delivery, and processing of invoices in a digital format.  

Key features of e-invoicing systems include digital signatures for authentication, and electronic storage for easy access and retrieval of invoice data. 

The 6 benefits of using e-invoicing software 

  1. Time-saving: E-invoicing saves time and makes life easier for businesses. Bid farewell to piles of paper – by automating tasks and getting rid of manual data entry and invoice reconciliation, businesses can streamline their processes and save precious time and resources. It’s a win-win situation! 
  1. Eco-friendly: E-invoicing is more than just about efficiency – it’s also good for our environment. By going digital, it helps us reduce paper waste and protect our valuable trees. It may seem like a small change, but it adds up to a big win for our planet.  
  1. Cost savings: By switching to electronic invoicing, you can say goodbye to the paper and postage expenses in traditional invoicing. It also reduces labour costs by automating the handling of invoices and minimising storage requirements – leading to some serious financial gains.  
  1. Better organisation: E-invoicing has a fantastic feature that enables improved organisation. It helps streamline your invoicing process, making it easier to manage and keep track of your invoices. With e-invoicing, you can enjoy a more efficient and organised approach.  
  1. Fewer errors: E-invoicing comes with the major benefit of reducing errors. You can say goodbye to handwritten paper invoices and the fear of misplacing important documents, because this digital solution is all about accuracy and precision. Forget about deciphering illegible handwriting, or messing up during manual data entry, because those days are over – embrace a smoother and more reliable invoicing process. 
  1. Improved cash flow management: Another benefit of e-invoicing is its impact on cash flow management. Thanks to the automation and faster processing of online invoices, businesses can expedite their payment cycle and get their hands on funds faster. This in turn helps maintain a healthier cash flow, allowing organisations to meet their financial obligations. You can also make strategic decisions based on a more accurate financial picture. It’s like having a money magician in your corner, making sure your cash is always flowing smoothly. 

Is e-invoicing required in the UK? 

In the UK, e-invoicing isn’t a blanket requirement for all businesses, but there are some important points to note: 

  • It’s on a voluntary basis: If you and your customer both agree to e-invoicing, then it’s game on! You can send those digital invoices without any legal hurdles. No specific format is forced upon you; just make sure the details are correct. 
  • Making Tax Digital (MTD): If you’re a UK VAT-registered business, they want your VAT return via an Application Programming Interface (or API, which connects the software you’re using to HMRC’s) .  
  • Archiving and integrity: Keep your e-invoices safe and sound for 6 years – they must be tamper-proof and ready for inspection. HMRC might knock on your digital door someday. 

So, while e-invoicing isn’t mandatory for everyone, it’s important for businesses to know the local regulations and adjust accordingly. The main goal of e-invoicing is to make things simpler, improve accuracy, and be eco-friendly. 

Is e-invoicing mandatory in the rest of the world? 

The requirements for e-invoicing differs from country to country, and even within different regions.  

In some places, like Italy, Brazil and Mexico, it’s mandatory for certain transactions. But in other areas, it may be more of a choice or something that’s encouraged rather than forced.  

E-invoicing regulations and compliance in Europe 

E-invoicing regulations can differ from one region to another in Europe. 

The EU Directive 2014/55/EU is an important regulation that has a big impact worldwide – setting the standard for e-invoicing in public procurement. The goal is to make things easier and more efficient for businesses when it comes to cross-border transactions within the European Union.  

You’ll also find that many European countries have their own specific mandates and regulations when it comes to e-invoicing, so businesses need to follow them when implementing their systems. For example, in Germany e-invoicing will be mandatory for B2B transactions by German-based businesses, effective from January 2025. 

To be ready for this change (or any others), your electronic invoices should have the correct format and content, complete with structured data for seamless automation. It’s also important to meet archiving requirements in order to keep a solid audit trail and fulfil your legal obligations. 

Tax authorities have an important role in e-invoicing, overseeing compliance and ensuring the correct application of tax regulations. This helps ensure a smooth process for tax control and auditability. 

How do you implement e-invoicing into your business? 

Getting e-invoicing up and running isn’t a walk in the park – it takes some careful planning and execution.  

Organisations need to follow specific steps to successfully adopt e-invoicing within their operations. This includes assessing their requirements, selecting the most suitable e-invoicing solution, and adequately training employees on the new system. Integration with existing accounting software is also essential for seamless data transfer. 

Now, even though e-invoicing is a game-changer, some challenges might come up along the way: 

  • People can be a bit resistant to change, and it can be difficult to switch up how they’ve been doing invoicing  
  • There might be some technical issues when trying to fit e-invoicing into existing accounting software 
  • It isn’t easy to stay compliant with regulations – things like invoice formats, structured data, and archiving can add an extra layer of complexity during implementation 

So, while e-invoicing brings many benefits, it’s good to be ready for a few hurdles along the way. 

How do you choose an e-invoicing solution provider? 

When it comes to choosing the perfect e-invoicing solution provider, you need one that’s reliable and works with your business needs. Are you a small local start-up or a growing global business? Understanding your size and business ambitions will help you find a provider that’s tailored to your scale. 

Next up, look for options that are user-friendly – you don’t want to find yourself lost in a maze of features. It’s also important to ensure compatibility with your existing systems. Your chosen provider should also take cybersecurity seriously. 

With the ease of digital transactions, small businesses can keep things organised, track payments, and avoid the hassle of manual paperwork. So, if you’re running a small business, consider making the switch to e-invoicing.

Small businesses can definitely benefit from electronic invoicing. It can help streamline their billing process, saving time and reducing the headache of dealing with physical documents. Plus, it’s environmentally friendly, cutting down on paper waste.
