What we are building, and what is happening to money in Britain.

People conflate the two constantly, and the difference is the part that matters most: who issues it, and who can attach rules to it.

Not generosity, and not a trick. They are sharing something they stopped paying somebody else — and it is cheaper for them than advertising.

It does not hold your money. It holds the proof that the money is yours, which is a stranger idea and a much better one.

Six mistakes that turn a simple set of accounts into an expensive one. Most of them look like nothing at the time.

It happens on a Sunday, badly, later than it should, by somebody who hates doing it. Which is exactly why late payers keep being late.

Every business software decision has two people in it. One of them signs up. The other decides whether it lasts.

Four things, in about a second, none of them mysterious. Worth knowing if only so you can tell when something is wrong.

The sensible move was America: bigger market, looser rules, more money. We did the opposite, and it has cost us time we are not getting back.

A percentage is easier to sell and grows on its own. It also means your success and our revenue are the same number, which sounds like alignment and is not.

Designers, developers, writers, photographers, bookkeepers. You did the work in March. The terms said thirty days. It is May.

You do not sell haircuts. You sell forty-five minute blocks of one person’s time, and every empty one is gone for good.

A shop haggles over pennies with suppliers and accepts a percentage on every sale without reading the statement. One of those is a negotiation. The other is a habit.

A table of eight that does not turn up on a Saturday is not a small loss. It is the best two hours of your week, given away for nothing.

A customer can show you they can cover the quote before you order the materials. You learn one thing and nothing else, which is why they will agree to it.

Electricians, plumbers, builders, fire and security installers. You bought the materials weeks ago and you are still waiting to be paid for them.

Low ticket, high volume, thin margin and a queue. Almost every quality of a café makes card fees worse than they are for anyone else.

A public ledger sounds like the opposite of private. The amounts were always visible; the part that says who you are never was, and that is the part worth protecting.

You sold a coffee. You did not buy an asset. HMRC disagrees, and the arithmetic — same-day, thirty-day, then the pool — is more particular than you would hope.

Sixteen digits that let anyone holding them take money from you, handed to every shop you have ever used. Plus the honest comparison, including what cards give you back.

Most small businesses do not fail because they were unprofitable. They fail because the money was always three days behind the bills.

A regulator publishing a rulebook is the least exciting news imaginable, and it is also the moment a technology stops being an experiment. What the June 2026 regime says.

A card terminal is a rented computer that takes a percentage. The alternative is a tag on your counter, and the customer makes the same gesture they already make.

Safe from what, specifically. Four things people actually mean, four straight answers, including the one that is genuinely worse than what you are used to.

Some numbers exist for a moment and then stop existing. If you did not write them down at the time, what you have later is an estimate wearing a number’s clothes.

The mechanism is simpler than you would expect. Reserves held, redemption promised, and the self-interest of strangers doing the rest.

Send them this. VAT at the time of supply, Section 104 pooling on disposals, and who is holding the money — answered properly rather than reassuringly.

Seventeen years from an experiment nobody understood to a payment method with a Bank of England rulebook. The interesting part is how dull it became.

Everyone knows a proportion of online reviews are invented. Almost no platform can tell you which ones. When the payment is the proof, there is nothing left to detect.

The money moves in milliseconds. The days are an arrangement between institutions, and we have simply got used to calling it speed.

Loyalty schemes have always been a good idea badly implemented. The plastic card was never the problem — knowing who came back was.

Nobody feels twelve pence. Everybody feels four thousand pounds. They are the same number, and that is before the three-day wait and the chargebacks.

The objection everyone reaches for first. A public blockchain is a permanent, published record of every transaction — the worst possible place to hide money.

Five minutes, no technical words, and no assumption that you know or care what a blockchain is. What it is, why it does not move in value, and three honest caveats.
