You sold £41,000 yesterday. Across TikTok Shop, Amazon and Shopify, the dashboards all agree: £41,000. Now check the bank. If you're like most of the founders I meet at £1m to £20m, the bank says something else entirely, and nobody in the building can explain the difference.
That gap is not a banking error. It's your settlement cycles, your fee structures and your reconciliation colliding at once. As a specialist social commerce accountant, I spend my days inside the books of brands running all three platforms together, and this collision is the most expensive blind spot I see.
Here's the honest version: you're not running one business. You're running three money machines, each with its own rules about what it takes, when it pays and what it tells you. The founder sees one P&L. The bank sees three settlement patterns. The books see whatever the bookkeeper could make sense of before month end. Those three views never agree. That's not a software problem. It's a design problem, and it has a price.
The Reality Check: Three Money Machines, Three Different Rules
TikTok Shop pays you on delivery, not on sale. Then it holds the money through a settlement period, then a few more days to move it. TikTok's own Seller Centre documents five settlement tiers: 31 days for new sellers, 8 days standard, 3 days accelerated, 1 day express, and a 31 day deferred tier. The transfer to your bank usually takes about 3 business days after the settlement period ends, and if your seller fault cancellation rate misses TikTok's criteria, a 30 day reserve gets applied. The platform takes 9% commission, 5% in eligible electronics and beauty categories, plus affiliate fees. TikTok's standard rate rose from 5% to 9% in September 2024, a near-doubling of your biggest fee line, and most founders only noticed at year end.
Amazon runs on a slower, chunkier rhythm. Most professional sellers are on a 14 day settlement cycle: your balance transfers every fortnight, and the money can take another 1 to 5 business days to land. You don't get paid per sale, you get paid in batches. Referral fees run 8% to 15% for most categories, with cuts over the last year: clothing and accessories dropped to 5% for items up to £15 in December 2025, the new Home Products category runs 8% for items up to £20 from January 2026, and FBA parcel fees fell by an average of £0.26 a unit. Good news, but your fee model changed twice in six months.
Shopify is the fast one, the only channel where the money moves like a normal business. Shopify Payments payouts start from 3 business days after a payment is captured, longer at first while you build a fulfilment history. The minimum payout is £1, and orders from Friday to Sunday consolidate into a single payout. Card processing runs roughly 1.5% to 2% plus 25p per online transaction depending on your plan, and here's the trap: any other gateway triggers Shopify's own fee on top, up to 2% per transaction on the Basic plan. The cheapest rate is only available if you use their processor.
What £2m Across Three Channels Actually Costs
Now the numbers that make founders go quiet. Take a £2m brand, split the way scaling brands actually look: £800k on TikTok Shop, £700k on Amazon, £500k on Shopify.
| Channel | Sales | Fee drag, worked | When you get paid | Cash in limbo |
|---|---|---|---|---|
| TikTok Shop | £800k | 9% commission, £72k, plus affiliate fees | 8 to 31 days after delivery, then ~3 business days | Up to £67k |
| Amazon | £700k | Referral fees 8% to 15%, around £105k in a 15% category, plus FBA | 14 day cycle, funds 1 to 5 business days later | £30k to £40k |
| Shopify | £500k | Cards at ~1.5% to 2% plus 25p, around £10k | From 3 business days | ~£4k |
Add it up. Nearly £190,000 a year in platform fees before you've paid for stock, ads or staff, and more than £100,000 of your own money parked in settlement cycles on any given day. You are lending the marketplaces your cash, interest free, permanently. That's why growing brands feel rich in the dashboard and poor in the bank. Our cashflow guide covers the shape of it, and ordering stock while the platforms hold your cash is in our stock vs cash piece.
The Reconciliation Trap: Gross, Net and the £12,000 Detail
Each platform hands you a different version of your own sales. TikTok's numbers are gross GMV, before commission, affiliate fees and refunds. Amazon settles you net, fees stripped out, in a settlement report that lists every line. Shopify shows the order value, then takes card fees out of the payout. Book what the bank shows and you lose the fee detail. Book what the dashboards show and you've recorded sales you never received. Most books I inherit are a blend of both, and nobody can tell me the real gross margin by channel. That's not bookkeeping. That's guesswork with a spreadsheet.
The second trap is VAT inside the fees. TikTok's 9% commission is inclusive of VAT. On that £72,000 of commission, £12,000 is input VAT you can reclaim, if your records actually show the fee separately. Amazon invoices its fees with VAT too, same principle. I've lost count of the brands leaving five figures a year in reclaimable VAT booked as a lump sum. One client, a six figure TikTok seller, had £2,000 of unclaimed input VAT in a single year before we looked at his books. It's on our case studies page, and the TikTok Shop VAT checklist walks through where this hides.
And don't fix it with three spreadsheets. Three sets of records for three channels is how you get a fourth set of numbers that matches none of them. You need one set of books with the channel as a dimension, so a single P&L can answer: what does this product make on TikTok versus Amazon?
The Finance Stack That Keeps Up
Right, here's the stack we actually run clients on.
One accounting system, channel coded. Xero, for our money, with the channel as a tracking category. QuickBooks works, but the marketplace ecosystem around Xero is stronger and the reconciliation tools plug in properly. Sales by channel, fees by channel, refunds by channel. Every report you need becomes a filter, not a rebuild.
Automate the settlement feeds. Tools like Link My Books pull Amazon, Shopify and TikTok Shop payouts straight into Xero, fee lines and all, so the gross and net detail survives. Manual reconciliation of three settlement formats is a full time job nobody wants to pay for. If your accountant says they'll do it manually each month, ask how many hours they're billing, because that cost lands on you either way.
Reconcile weekly, not monthly. At £1m plus, monthly is archaeology. You need to know this week that a commission change moved your margin by a point, not discover it at year end. Three numbers, every week: gross sales by channel, net settlement by channel, fees by channel. If they don't tie to the settlement reports, something's wrong, and cheaper to find at three days old than three months.
Treat fee changes as events. TikTok raised commission 50% in January. Amazon cut referral fees in December and again in January. A generic bookkeeper won't notice either change. Someone who lives in marketplace settlements will flag it before you ask. If you're wondering whether your finance function can deliver that, our financial controller piece sets out the test.
HMRC Already Has Your Numbers
One more reason this matters, and it's the one I'd build the whole system around. Under HMRC's digital platform reporting rules, TikTok and Amazon already report seller information to HMRC every year: who you are, what you were paid, fees withheld, transaction counts. The small seller exemption, under €2,000, roughly £1,700, and fewer than 30 sales of goods a year, doesn't touch you at £1m plus. You are reported, annually, by 31 January for the previous calendar year.
In plain English: HMRC already knows what the platforms paid you. Your declared turnover needs to reconcile to that through a documented bridge (timing, refunds, VAT, gross-to-net differences), or you get to explain the difference. The brands that sleep well are the ones whose books match the platform reports. Sloppy records stopped being a private problem the day digital platform reporting went live.
Frequently Asked Questions
Why doesn't my bank balance match my sales dashboards?
Because none of the platforms pay you what the dashboard sells. TikTok holds settlements up to 31 days after delivery, Amazon pays on a 14 day cycle, only Shopify moves money within days. Add fees, refunds and reserves, and the gap is normal.
Do I need separate books for each marketplace?
No. One set of books, channel coded. Separate spreadsheets or files per channel is how you end up with three versions of the truth and no way to price a product properly. The channel is a dimension in your chart of accounts, not a second business.
What's the best accounting software for multi marketplace selling?
Xero, paired with a settlement tool like Link My Books, is the combination we run clients on. QuickBooks is fine, but the marketplace integration ecosystem around Xero is stronger. The software matters less than the structure: sales, fees and refunds coded by channel.
Can I reclaim VAT on marketplace fees?
If you're VAT registered and the fee carries VAT, yes. On £72,000 of TikTok commission, that's £12,000 of input VAT. The catch is records: the fee has to be visible as a fee, not buried in a net settlement. Check your registration position against the £90,000 threshold while you're at it, because that line hasn't moved.
How often should I reconcile?
Weekly from £1m. The platforms move too fast and the fee structures change too often for monthly. Three reports, every week, tied to the bank. With automated feeds it's an hour a week.
Do Amazon and TikTok report my sales to HMRC?
Yes. Under digital platform reporting, both file annually on UK sellers by 31 January, with only a small seller exemption. Your numbers and their numbers need to agree, and that starts with the books.
Summary: One Set of Books, One Version of the Truth
Running TikTok, Amazon and Shopify together isn't three businesses. It's one business with three very different ways of getting paid, and the finance stack either reflects that or it doesn't. When it doesn't, you lose the fee detail, you lose the VAT reclaims, you lose track of £100,000 of your own cash in settlement limbo, and HMRC has better records of your sales than you do.
When it does, you get the one thing every scaling brand needs: a number you can trust, this week, per channel. That's the whole game. Turnover is vanity, profit is sanity, cash is reality, and in a multi marketplace business, all three live or die on the reconciliation.
