This week: why context, not access to AI, will create competitive advantage, how associated-company rules can reduce Corporation Tax thresholds, and which simple, integrated finance tools can give a new consultancy or service business a strong foundation.

1. The New Competitive Advantage Isn't AI. It's Context.

If you've spent any time on LinkedIn recently, you'd be forgiven for thinking AI is the competitive advantage.

It isn't.

ChatGPT, Claude, Gemini... they're all becoming table stakes. Anyone can open a browser, ask a question and get a decent answer. That's no longer where the edge is.

The businesses that will pull away over the next few years are the ones that can give AI context.

Imagine asking AI to draft a proposal. Without context, it'll produce something perfectly acceptable. Generic. Forgettable.

Now imagine it has access to your meeting transcript, previous proposals, pricing model, client emails, CRM notes and internal knowledge base. Suddenly it's producing something that actually sounds like your business and reflects the conversation you had yesterday.

That's a completely different proposition.

The same applies across the board. Client emails. Meeting summaries. Knowledge sharing. Internal processes. Reporting. The quality of the output is determined less by the AI model and more by the quality of the information you feed it.

That's why we're spending far more time thinking about how systems connect than which AI tool is flavour of the month.

Most businesses already have the data. It's just trapped in inboxes, PDFs, meeting notes and half a dozen disconnected apps.

The winners won't necessarily be the businesses using the most AI. They'll be the ones who've done the hard work of organising their information so AI can become genuinely useful.

Knowledge used to be power. Now, accessible knowledge is.

2. HMRC Is Looking At Associated Companies

If you've got more than one limited company, this one's worth paying attention to.

HMRC has started writing to businesses it believes have incorrectly said they have no associated companies. Why? Because getting this wrong can mean you've underpaid Corporation Tax.

The rules aren't new, but since Corporation Tax rates changed a couple of years ago they've become much more expensive to ignore.

In simple terms, if two or more companies are under the common control of the same person (or people), they're likely to be associated. That could be a trading company and a holding company. It could be two separate trading businesses. In some cases, family ownership comes into the equation too.

The impact isn't that you pay more tax just because you have two companies. It's that the Corporation Tax thresholds have to be shared between them.

So instead of getting the full £50,000 small profits threshold, two associated companies only get £25,000 each. Five companies? Just £10,000 each.

We've already seen HMRC using Companies House data to identify businesses that may have got this wrong. If they think you've declared zero associated companies when you shouldn't have, don't be surprised if a letter lands on your desk.

If your business has more than one company in the structure, or you're thinking about setting one up, it's worth checking the position now. A ten-minute review today is a lot cheaper than explaining it to HMRC later.

3. My Recommended Finance Stack For New Consultancies and Service Businesses

If I was starting a consultancy or other service business in 2026, I wouldn't waste time comparing dozens of apps. I'd get the basics right and get on with finding clients.

Here's the stack I'd start with.

Accounting software: FreeAgent. If that wasn't an option, Xero.

Business banking: Mettle. Second choice, Starling.

Collecting recurring payments: GoCardless. If that didn't fit, Adfin.

Invoice and receipt capture: Dext. If the budget was tight, Hubdoc.

Could you run a business using different apps? Absolutely. There are plenty of good alternatives.

The point isn't that these are the only options. It's that having a simple, integrated finance stack from day one saves an incredible amount of time and frustration later. These tools talk to each other, automate the boring bits and give you a solid foundation to build on.

As your business grows, you can add specialist tools where they genuinely add value. Reporting software, expense cards, forecasting tools and cash flow apps all have their place.

But don't start there. Keep the foundation simple. You'll spend less time doing admin and more time doing the work that actually earns you money.
