From 1 April 2029, all VAT-registered businesses will need to change the way that invoices are handled.

Despite it being less than three years until the deadline, only nine per cent of SMEs are even aware that a change is coming.

Whether you have heard of the new rules or not, now is the time to learn what they are and how to prepare.

What is changing with e-invoicing?

Amidst all the chaos and excitement of the 2025 Autumn Budget, you may have missed the announcement that, from 1 April 2029, businesses will be required to issue all VAT invoices as e-invoices.

This does not mean that it will be sufficient to type up an invoice and send it as a PDF, but will instead need to be formatted in such a way that it can be transmitted between accounting software and read therein.

The stated goal of the measures is to assist businesses in tackling the deeply rooted issue of late payments that can cause immense harm to a business.

The Government note that e-invoices can reduce late payments by as much as 20 per cent and this mandatory adoption is done with the aim of achieving this objective.

However, HMRC discovered that 69 per cent of SMEs had not used e-invoicing at all and a staggering 91 per cent had not heard of the plans to universally adopt the system.

Understandably, it may take some time for those unfamiliar with e-invoicing to adopt the new system and it would benefit them to begin those preparations now.

How should businesses prepare for new e-invoicing rules?

As has become apparent with other major overhauls, like Making Tax Digital for Income Tax, early adoption and preparation is the most effective way of reducing the risk of errors and alleviating stress.

If you are using e-invoicing already, you will need to check with a professional or the provider of the software whether you are doing enough to meet the upcoming requirements.

For any business not yet using e-invoicing, take these months and years to get ready so that you do not find yourself in a panic when the deadline hits.

Reviewing your current practices and determining which of the many software services on the market best suits your needs will be vital in ensuring that this does not become an administrative hassle.

It is expected that a full timeline and road map will be unveiled in the 2026 Autumn Budget, after which there will be a clearer sense of what should be done and when.

However, given that the aim is to help businesses tackle the over-persistent problem of not being paid properly, it would be unwise for businesses to ignore these changes.
