Let's be honest: when did you last learn anything from your accountant?

I don't mean the tax return. The tax return gets filed, that's fine. I mean the conversation where you asked a real question and walked away with an answer you could use. Something like "what's my gross margin after TikTok Shop fees?" or "how much cash do I need for the next stock order?" If the answer you got was a shrug, a pause, or a subject change, read on.

As a specialist social commerce accountant, I spend my days inside the books of UK brands doing between £1m and £20m. I see the same pattern over and over: the business outgrows the accountant, and nobody says it out loud. The founder keeps paying the fee out of loyalty. The accountant keeps filing the return out of habit. And the gap between the two is where the money quietly leaks out.

Getting to £1m is a different job from running a £1m business. And the accountant who got you there is very often not the one who gets you through it. So how do you know when you've outgrown them? Here are the seven signs I see every week.

Sign One: They've Never Asked to See a Settlement Report

Your platform payout report is not a bank statement. It's an invoice, a receipt, a fee schedule and a settlement summary all rolled into one. It's also where your margin is actually decided, not on your product page.

A product you price at £15 doesn't give you £15. After the referral fee, the payment processing fee, the fulfilment cost and the returns you'll refund one time in ten, you've got £6.57. If your accountant has never asked to open a TikTok Shop settlement report or an Amazon FBA statement, they are working blind on the most important number in your business.

I've lost count of the brands who walked in with five-figure VAT reclaims sitting unclaimed because nobody was reconciling their settlement reports properly. The money was there. The system wasn't. And the accountant never asked.

Sign Two: Your "Management Accounts" Arrive Quarterly, If at All

At £500k, year-end accounts once a year are fine. At £2m, they're archaeology. By the time the pack lands in September, the numbers are four months old and full of adjustments nobody warned you about.

The test is simple. Can you tell me, right now, what your gross margin was last month, by channel, after platform fees? If the answer is "roughly", your accountant is doing compliance, not accounting. Compliance is filing what already happened. Accounting is telling you what's happening now, while you can still do something about it.

Sign Three: They Still Quote 19% Corporation Tax

If your accountant says "you'll pay 19% corporation tax" and leaves it there, they're quoting a rate that stopped applying to growing companies years ago.

The current rules are simple enough: profit of £50,000 or less, you pay 19%. Profit over £250,000, you pay 25%. In between, marginal relief tapers you up. On £300,000 of profit, that's £75,000 of tax at 25%, not £57,000 at 19%. An £18,000 difference. Your accountant should be planning around that gap, not quoting the old number.

And if you've got multiple companies, watch out. The £50,000 and £250,000 thresholds get divided by the number of associated companies you have. Two companies, the thresholds halve. Most founders find this out the expensive way.

Sign Four: They've Never Mentioned Making Tax Digital for Income Tax

If you're still a sole trader or a partnership, this one's for you. Making Tax Digital for Income Tax is not coming. It's here.

If your income was over £50,000 in 2024-25, you should have started using it from 6 April 2026. That's already happened. The net tightens to £30,000 from April 2027, and then to £20,000 from April 2028. At that point, nearly every serious seller is in.

If your accountant hasn't mentioned any of this, ask yourself why. It's one of the biggest changes to how UK small businesses report income in decades, and it's been on the calendar for years. What else are they not on top of?

Sign Five: They Don't Know the Platforms Report Your Income to HMRC

Here's a fact that still surprises founders: TikTok, Amazon and Shopify all report seller income to HMRC under the digital platform reporting rules. The data matching is automatic. HMRC doesn't need to guess what you sold. The platforms tell them.

What that means is brutal and simple. Your books need to tie back to what the platforms reported, to the penny. If they don't, you'll be the one explaining the difference in an enquiry letter, and "my accountant handles it" is not a defence HMRC accepts.

If your accountant doesn't know the platforms report your numbers, they don't know your risk profile. And you're carrying that risk, not them.

Sign Six: VAT Is a Twice-a-Year Panic, Not a System

The £90,000 VAT registration threshold is a distant memory for you. At £1.5m of standard-rated sales, roughly £250,000 of VAT flows through your bank account every year. That is not your money. It's HMRC's, sitting in your account, and you get to fund their cashflow with yours if the reconciliation is off.

A system looks like this: VAT accounted on the sale price, not the payout. Marketplace-collected VAT separated from your own. EU distance sales going through the OSS Union scheme so you're not registering for VAT in six countries one at a time. VAT reclaimed on your TikTok Shop fees, your FBA fees, your warehouse rent.

A panic looks like this: a folder of export files in September and a prayer. If that's you, our VAT registration checker takes two minutes, and the TikTok Shop VAT checklist covers the specific traps on that platform. But the real fix is the system, and the system is your accountant's job.

Sign Seven: Stock Is a Year-End Mystery to Them

Ask your accountant what your true landed cost per unit is. Product cost, freight, customs, FX, FBA fees, TikTok commission. If they look at you blankly, you've found sign seven.

Growth eats cash, and stock eats it fastest. At £1m you order inventory when you're nearly out and it's fine. At £3m you're committing five figures to a container three months before you sell a single unit. If that product flops, the cash is gone for a year. You can be profitable on paper and bankrupt in the bank. I've watched it happen.

Your accountant should be asking how much cash the next 90 days of stock orders need, and where it's coming from. That's the difference between cashflow forecasting that protects you and a fire sale that finishes you.

What a £1m+ Accountant Actually Does

Here's my contrarian take: your accountant isn't a bad person, and they might not even be a bad accountant. They're the wrong size. A general practice built around compliance can't serve a business moving at your speed, and no amount of goodwill fixes that.

The job at your level looks completely different. Platform accounts reconciled every week, not every quarter. A chart of accounts where TikTok Shop fees sit on their own line, so you can see what the channel actually costs you. A monthly close you trust by the first week of the month. Tax planning that starts before the year ends, not after. Stock and cash treated as one problem, not two.

We get brands between £1m and £5m to a clean, reconciled picture within about four weeks, including the platform data they've never seen properly. That's not a brag, it's the standard the job requires. If you're wondering whether you're getting it, read what happened to brands at your stage in the £1m revenue trap, and what the systems fix looks like in Scaling from £1M to £5M.

Frequently Asked Questions

How do I test whether my accountant has outgrown me?

Ask three questions in your next meeting: what's my gross margin by channel after platform fees, what's my true landed cost per unit, and have the platforms reported my income to HMRC yet? If you get three blank stares, you have your answer.

Should I fire my accountant now or wait for year end?

Now. The problem isn't the filing, it's the data. Every month you stay, the mess gets deeper, and the clean-up gets pricier. You don't need to make a scene, you just need to move.

My accountant is cheap. Doesn't that count for something?

Cheap compliance is the most expensive thing in your P&L. At your size, one missed reclaim, one unreconciled settlement report or one enquiry letter costs more than a decade of fees. The fee is irrelevant. The risk is everything.

Can a good bookkeeper fix this instead?

A bookkeeper keeps the records tidy. That's valuable and it's not the same job. You need someone who reads the records and tells you what they mean for cash, tax and margin. Different skills, different person.

What if I'm not at £1m yet?

Then you've got time, and you should use it. Put the systems in before you need them. Every brand I've seen stall at seven figures could have fixed it in a weekend at £600k. By £2m it's a project.

Summary: You Haven't Outgrown Your Business, You've Outgrown Your Accountant

Seven signs. Settlement reports they've never opened, management accounts that arrive late, tax rates from a previous era, MTD they never mentioned, platform reporting they don't know about, VAT as an annual panic and stock as a mystery. Any one of them is a problem. Three or more and you're leaking money every single month.

Here's the thing to remember. The tax return gets filed either way. The difference is whether you know your numbers well enough to make the calls that matter, before the year end, while you can still change the outcome.

You built the machine that sells. Now get someone who counts what it actually makes, because the counting is where the profit is hiding.

If you're doing £1m+ across TikTok Shop, Amazon or Shopify and any of these signs felt familiar, book a call. We'll tell you what's actually wrong in the first conversation. You can see how we work with brands like yours on our case studies page, and if you're TikTok Shop heavy, we live in the settlement reports: that's our world.
