From 1 January 2026, the new revenue recognition standard introduced a structured five-step model for recognising revenue (download our factsheet). But while most of the focus has been on how revenue will be recognised going forward, there’s a more immediate question that often gets less attention:

How do you transition into the new rules?

It might sound like a technical accounting choice, in reality, It’s anything but.

The decision that shapes your numbers

When adopting the new standard, businesses have two options:

• Apply the rules as if they’ve always been in place (full retrospective)
• Or apply them from the transition date only (modified retrospective)

On paper, both achieve compliance.

In practice, they can lead to very different outcomes. This isn’t just about how revenue is recognised, it’s about how your business performance is presented, understood and challenged.

Same business. Different story.

The transition approach you choose can significantly influence how your numbers look in the year of adoption and beyond and we’re already seeing businesses underestimate the impact this can have.

For example:

• Revenue may shift between periods, making growth appear stronger or weaker than it really is
• Year-on-year comparisons can become harder to explain
• KPIs and internal reporting may no longer align with historic trends
• Stakeholders may question movements that are purely accounting-driven

Nothing has changed operationally, but the story your numbers tell has.

Why this matters beyond finance

It’s easy to view this as a finance team decision, but the implications stretch much further.

Boards will need to understand changes in reported performance, investors and lenders may challenge apparent volatility. Bonus structures and targets could be impacted. Sales and operational teams may need to rethink how contracts are structured and measured, so it’s as much a commercial consideration as it is an accounting requirement.

Where complexity really sits

Not every business will feel the impact equally. For example, those with simple, short-term contracts may find the transition relatively straightforward. But for others, the challenge increases quickly. Businesses with long-term contracts, bundled services, milestone billing or variable consideration will often need to revisit historical data, reassess performance obligations and apply significant judgement. In these cases, the transition becomes as much about data, systems and interpretation as it is about accounting rules.

Choosing the “right” approach

The reality is, as demonstrated above, there’s no universal answer. The full retrospective approach provides consistency and a cleaner long-term view, but often requires significant time and resource. The modified approach is more practical and less resource-intensive, but can make performance harder to interpret in the short term.

The right choice depends on your business, your stakeholders and how important comparability is to your story. What matters most is making that decision deliberately and not by default.

What businesses should be doing now

The businesses that will handle this well are already moving. They’re stepping back to understand the implications of both approaches, reviewing the contracts that will drive the outcome, and modelling how their numbers will look under each scenario. They’re also bringing auditors, boards and stakeholders into the conversation early, so there are no surprises later, because once the numbers are published, the narrative is already set.

Final thought

Revenue recognition has always been about judgement. The transition into the new standard is no different – handled well, it provides clarity and consistency, but handled poorly, it creates confusion and unnecessary questions.

The earlier you address it, the more control you retain over the story your numbers tell.
