The UK government has confirmed it is mandating electronic invoicing for most VAT-registered businesses from 1 April 2029; and while that might sound like a long way off, the businesses that find this transition smooth will be the ones that started thinking about it early.
We have been watching this closely for a while and as of 7 August 2026, Right Click Accounting is already registered on the Peppol network and testing the process. This post covers what e-invoicing actually is, why the government is pushing it and (most importantly) what you can do now to make sure your business is ready.
What E-Invoicing Actually Is
Most people assume e-invoicing just means sending a PDF by email, when in reality it’s the structured, digital exchange of invoice data directly between software systems. This means no manual entry, no chasing attachments, just clean automated exchange of invoices.
The UK is adopting the Peppol network as its standard and they’re already an internationally recognised framework used across Europe. Once registered, your invoices talk directly to your clients’ systems and theirs talk back to yours, automatically.
So what does that actually look like day to day?
✔ Sales invoices sent digitally through a compliant system, directly to your client’s software rather than as an email attachment.
✔ Purchase invoices received the same way, landing straight into your accounting software without any manual processing.
✔ Faster payments with fewer delays caused by lost emails, incorrect formats or manual keying errors.
✔ A cleaner audit trail with invoice data flowing directly between systems, the record is automatic and consistent.
Why the Government Is Doing This
This is part of a broader push to tackle late payments, reduce fraud and improve financial transparency across UK businesses. The logic is straightforward; when invoice data flows directly between systems, it is harder to manipulate, easier to audit and less likely to get lost in someone’s inbox.
It sits alongside the Fair Payment Code, led by the Small Business Commissioner, which is pushing for faster and fairer payment practices across the board.
The government’s consultation response sets out the full reasoning behind it, but the headline is…“E-invoicing is coming, and 2029 will be here faster than you think.”
How Xero Is Making This Easy
Xero is one of the first accounting platforms to launch Peppol registration functionality in the UK, which means businesses already using Xero can get set up well ahead of the 2029 deadline!
Registration is straightforward. You will need your business name, VAT number and primary contact details, and once registered your business appears on the Peppol directory and can begin sending and receiving e-invoices through Xero immediately.
Xero’s full guidance on registering is available here.
We're Testing The Process So You Don't Have To
We officially registered Right Click Accounting on the Peppol network in August 2026 (via Xero) as we wanted to understand exactly how this works in practice, not just in theory, before it becomes a requirement for the businesses we work with.
As part of that, we requested to receive our own Xero subscription invoice as an e-invoice to test the process end-to-end, and it works exactly as it should! You can see our listing on the Peppol directory right now.
The reason we are sharing this is not to show off, it’s because knowing it works and how straightforward the setup is, means we can tell you with confidence that this is not something to be anxious about. Get set up early, test it with a low-stakes invoice, and by the time 2029 arrives it will already feel like second nature.
How to Prepare for E-Invoicing
April 2029 gives you time to adjust, especially if your current processes or software need updating. Here is what we recommend working through now.
Step One: Confirm whether you are in scope.
The mandatory requirement applies to VAT-registered businesses. If you are not VAT-registered, e-invoicing is unlikely to be a legal obligation for you; though some clients, particularly larger businesses and public sector organisations, may start requiring it from their suppliers before the mandate kicks in. It is worth being aware of that regardless.
Step Two: Check your accounting software.
Not all software is ready for this yet. Xero is already equipped for the change but if you use a different platform, check with your provider what their plans are for e-invoicing compliance. The sooner you know whether your current setup will support this, the more time you have to make changes if needed.
Step Three: Register on the Peppol network.
If you are on Xero and VAT-registered, there is nothing stopping you from registering today. You will need your business name, VAT number and primary contact details. Then once you are on the Peppol directory, you can start sending and receiving e-invoices immediately. Xero’s registration guidance is here.
Step Four: Think about your internal processes.
E-invoicing changes the day-to-day flow of how invoices are raised and processed. Think about who in your business creates invoices, who processes incoming ones and what the current workflow looks like. The sooner you understand where the changes will land, the easier it will be to adapt when the time comes.
Step Five: Talk to your bookkeeper or accountant.
This is not just a software change as it also impacts your invoicing workflow, your audit trail and potentially how you manage supplier relationships. Your bookkeeper or accountant should be able to assist and help you plan for it. If they are not talking to you about it yet, it is worth asking if it’s on their radar.
Frequently Asked Questions
Your existing invoice templates will not simply disappear, but they will need to work within a compliant e-invoicing system rather than being sent as standalone PDFs. In practice, if you are using software like Xero, your invoice data will be sent in a structured digital format automatically. (Meaning the information stays the same, it is just the way it travels that changes). It is worth reviewing your current templates now to make sure all the required fields are present and accurate.
Yes for a true e-invoice to be exchanged, both sender and recipient need to be registered on the Peppol network. If your client is not yet registered, the invoice cannot be delivered that way. That said, most accounting software will still allow you to send invoices through alternative methods in the meantime, and as the 2029 deadline approaches, Peppol registration will become increasingly standard across UK businesses.
The UK mandate applies to VAT-registered UK businesses, but Peppol is an international network already used across Europe and beyond, so cross-border e-invoicing is entirely possible where both parties are registered. For international invoices specifically, the rules will depend on the country your client is based in and whether they have their own e-invoicing requirements. This is an area worth discussing with your accountant if international trade is a significant part of your business.
Actually the opposite as the e-invoices create a cleaner, timestamped digital record of exactly what was sent and when, which makes disputes easier to resolve rather than harder. There is no ambiguity about whether an invoice was received, no lost emails to chase and no question over what version was sent. That audit trail is one of the genuine advantages of the switch.
Final Thoughts
E-invoicing is one of those changes that feels distant until suddenly it is not. April 2029 sounds like a long way off, but the businesses that find this transition effortless will be the ones that took an hour to understand it now rather than a panicked week in 2028.
We are already registered, already testing and already helping clients think through what this means for them. If you want to be in that same position (confident, prepared and ahead of the curve) we would love to be the people who help you get there.
