Let's be honest: getting past £1m didn't fix anything. It just raised the stakes.

You're doing £2.4m across TikTok Shop, Amazon and Shopify. The orders are coming in faster than the team can pack them. You hired three people last quarter and you'll hire three more this one. And the accounts? Still the same spreadsheet your bookkeeper updates "when they get round to it".

I see this exact scene every week. As a specialist social commerce accountant, I spend my days inside the finance systems of brands doing between £1m and £5m. And I can tell you the pattern: the business scales, the numbers don't, and the gap between the two is where the money quietly leaks out.

The jump from £1m to £5m isn't a bigger version of the jump from £100k to £1m. It's a different sport. Last week I wrote about the £1m revenue trap: why brands stall at seven figures. This is what happens after you get through that wall, when the volume really starts moving.

The Reality Check: What Multiplies When Revenue Multiplies by Five

Five times the revenue doesn't mean five times the work. It means five times the transactions, five times the fees to chase, five times the stock sitting in a warehouse, and five times the VAT flowing through your bank account. Most of it isn't even yours.

Run the numbers with me. At a £40 average order value, £5m of revenue is 125,000 orders a year. That's roughly 340 orders a day. Every day you don't reconcile, you add 340 transactions of drift to a pile you'll never want to dig through. At £2m, you can catch up over a weekend. At £5m, you can't.

Then there's VAT. On £5m of standard-rated sales, roughly £833,000 of VAT flows through your bank account every year. That is not your money. It's HMRC's, sitting in your account, waiting for the quarter end. Get the reconciliation wrong and you're funding HMRC's cashflow with your own.

And the platforms are watching. TikTok, Amazon and Shopify all report seller income to HMRC under the digital platform reporting rules. The data matching is automatic. If your books don't tie back to what the platforms reported, you'll be the one explaining the difference in an enquiry letter.

System One: A Chart of Accounts Built for E Commerce

Most brands at this stage are running on a chart of accounts designed for a window cleaner. One "sales" line. One "cost of goods" line. Maybe a "fees" line if someone got fancy.

That doesn't work at £2m+. You need sales split by channel, because TikTok Shop and Amazon and Shopify all charge differently. You need platform fees, referral fees, payment processing, fulfilment, refunds, promotions and TikTok credits as separate lines. Because if you can't see TikTok Shop fees on their own, you can't see what TikTok Shop actually costs you.

Here's the test I give every founder: can you tell me, from your P&L alone, what your gross margin was last month after platform fees? If the answer is "roughly", your chart of accounts is the problem. The fix is boring and cheap: a week of properly mapping your accounts, done once, and it pays for itself every month after.

System Two: Reconciliation You Can't Skip

Platform payout reports are not bank statements. They're invoices, receipts, fee schedules and a settlement summary all rolled into one, and they're full of deductions you never agreed to in the shop window.

Your margin is decided in the settlement report, not on the 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 return you'll refund one time in ten, you've got £6.57. And if your accounting system books the full £15, your P&L is lying to you by about 56%.

The brands that scale past £2m without the wheels coming off reconcile platform payouts to the penny, every week. Not every month. Not every quarter. Every week. It takes two hours once the system is set up. The alternative is a five-figure surprise at year end, and I've seen plenty of those. We've had clients walk in with five-figure VAT reclaims sitting unclaimed because nobody was reconciling their TikTok Shop settlement reports properly. The money was there. The system wasn't.

System Three: VAT Handled in the Software, Not in a Panic

VAT at £1m is annoying. VAT at £5m is a cashflow event.

You're well past the £90,000 registration threshold, so that's done. The questions now are mechanical: are you accounting for VAT on the sale price, not the payout? Are you separating marketplace-collected VAT from your own? Are your EU sales going through OSS so you're not registering for VAT in six countries one at a time? Are you claiming back the VAT on your TikTok Shop fees, your Amazon FBA fees, your warehouse rent?

The tools exist. Our VAT registration checker takes two minutes, and the TikTok Shop VAT checklist covers the specific traps on that platform. The point is the VAT return should come out of your reconciled books, not out of a folder of export files. If your bookkeeper is building the return from spreadsheets, you're one mistake away from a very expensive conversation with HMRC.

System Four: Stock and Cash, Treated as One Problem

Here's the thing nobody warns you about: growth eats cash. Stock eats it fastest.

At £1m, you order inventory when you're nearly out and it's fine. At £5m, you're committing five figures to a container three months before you sell a single unit, and 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.

You need to know your true landed cost per unit: the product cost, the freight, the customs, the FX, the Amazon FBA fees, the TikTok commission. Then you need a forecast that asks the question your accountant should be asking: how much cash do the next 90 days of stock orders need, and where is it coming from?

This is where cashflow forecasting and proper inventory accounting stop being textbook terms and start being the difference between a great year and a fire sale.

System Five: A Monthly Close You Actually Trust

By the first week of the month, you should know three things: the real profit for last month, the cash position, and what's coming next month. That's it. That's the whole job.

Most £2m brands know none of them until the accountant's year-end pack arrives in September, four months late and full of adjustments. That's not accounting. That's archaeology.

A proper close is: bank and platform accounts reconciled, stock counted and valued, accruals booked, VAT return filed from reconciled data, and a one-page management summary. It takes a good system and a person who runs it.

And on the tax side, the stakes are rising whether you like it or not. Above £250,000 of profit you're paying Corporation Tax at 25%, not the 19% small profits rate your old accountant still quotes. On £500,000 of profit, which is a 10% net margin at £5m, that's £125,000 of tax.

If you're still a sole trader, Making Tax Digital for Income Tax has you already: over £50,000 of income and you were in from April 2026, with the net tightening to £30,000 from April 2027. And the moment you hire, the £10,500 Employment Allowance should be cutting your payroll bill. These are free points. Most brands don't claim them properly.

My Contrarian Take: Don't Hire a Financial Controller Yet

Everyone's instinct at £2m is to hire a financial controller. Mine is the opposite: fix the ledger first.

A financial controller can't fix a system that records garbage. They'll spend six months cleaning up a chart of accounts that should have been sorted in a week, and you'll pay £70k a year for the privilege. Sort the systems, then hire the person to run them. And if you're choosing software, for UK e commerce I'd pick Xero over QuickBooks every time. The e commerce apps, the MTD filing, the bank feeds, the whole ecosystem works better for this kind of business. That's a hill I'll die on.

Frequently Asked Questions

How often should I reconcile TikTok Shop payouts?

Weekly. Two hours a week once the system is set up. At £3m+ you can justify daily if the volume is wild.

When do I actually need a financial controller?

When your month end takes more than two weeks, or when you're making decisions on numbers that are more than a month old. Usually somewhere between £3m and £5m. But only after the systems are sorted, or they'll spend their first year cleaning.

My accountant says the books are fine. Should I get a second opinion?

If your accountant has never asked to see a TikTok Shop settlement report, get the second opinion. The compliance can be perfect and the management information useless. They're different jobs.

Is my spreadsheet good enough at £2m?

No. And it's not about the £30 a month you're saving. It's about what a spreadsheet can't tell you: gross margin by channel, true landed cost, cash runway. At £1m those are nice to know. At £5m they're the whole game.

How long does it take to fix this properly?

For most brands between £1m and £5m, we have the full picture clean and reconciled within four weeks, including the platform data you've probably never seen properly. The systems after that run themselves. That's the point.

Summary: Turnover Is Vanity, Profit Is Sanity, Cash Is Reality

The difference between the brands that stall at £2m and the ones that push through to £5m isn't luck and it isn't harder work. It's systems. The five above: a real chart of accounts, weekly reconciliation, VAT handled in the software, stock and cash treated as one problem, and a monthly close you trust.

None of it is complicated. All of it is skipped until it hurts. And by the time it hurts at £5m, it's a six-figure problem instead of a two-hour fix.

You've built the machine that sells. Now build the one that counts, before the counting catches up with you.
