Introduction — Three Hundred and Forty Pounds
Four months of Wednesdays is evidence of habit, not permission - and habit cannot be shown to anybody.
The Arrangement
⚠ Bea started running errands the way almost everybody starts running errands, which is by accident.
A neighbour's car was off the road for a fortnight. Bea was going to the shops anyway. She picked up a few things, the neighbour gave her a twenty, and that was that.
Three weeks later the neighbour's sister rang and asked whether Bea would do the same for her.
By the end of that summer Bea had eleven people. Shopping, parcels, returns, dry cleaning, garden centre runs, the post office, the tip, the pharmacy. She had a spreadsheet, a magnetic sign for the car door, and more work than she could comfortably fit around her other job.
⚠ ⚠ She had, by any ordinary measure, a business.
⚠ ⚠ ⚠ What she did not have was a single piece of paper.
Wednesdays
The best client was a man in his eighties, four streets away. Every Wednesday morning Bea did his shopping.
It was the easiest work she had. He wanted the same things. He liked one particular brand of marmalade and did not want a substitute. He had a list, always in the same handwriting, always on the same pad, always left under a flowerpot by the back door.
⚠ Bea paid at the till with her own card, brought the shopping in, put the cold things away, and left the receipt on the counter.
⚠ ⚠ On Friday, when she came past with his parcels, he gave her cash: the shopping money and her fee, in an envelope, at the kitchen table.
It worked perfectly for four months. It never once went wrong. It felt, if anything, like the most solid part of the whole operation — a regular slot, a regular client, a regular envelope.
⚠ ⚠ ⚠ Then, on a Tuesday night in November, he had a fall.
What Happened Next
The ambulance came. He was in hospital for six days and then in a rehabilitation ward, and it became clear fairly quickly that he was not going to be living alone again.
⚠ Bea did not find any of this out for eleven days.
She did the Wednesday shopping as normal, because the list was under the flowerpot where it always was — written the previous Sunday. She let herself in with the key he had given her, put the shopping away, left the receipt, and went home.
She did it again the following Wednesday, because nobody had told her not to, and because there was no list but she knew what he wanted, and because she assumed he was away with family.
⚠ ⚠ On the third Wednesday the locks had been changed and there was a card in the window with a phone number on it.
⚠ ⚠ ⚠ By then Bea was out of pocket by three hundred and forty pounds: two weeks of shopping she had paid for herself, plus the Friday envelope she had not received for the week before the fall, plus a prescription charge, plus a parcel she had paid a redelivery fee on.
The Daughter
⚠ The number on the card belonged to his daughter, who lived two hundred miles away and held power of attorney.
She was not unkind. She was not unreasonable. She was dealing with a parent in a rehabilitation ward, a house that needed emptying, and a set of financial affairs she had inherited overnight and did not yet understand.
And into that, a woman she had never heard of rang up asking for three hundred and forty pounds.
⚠ ⚠ Bea had supermarket receipts. That was all.
The receipts proved that somebody had bought groceries. They did not prove who had asked for them, who they were for, what had been agreed, what Bea's fee was, whether she had permission to enter the house, whether she had permission to keep buying after the fall, or whether any of this had ever been sanctioned by anyone.
⚠ ⚠ ⚠ From where the daughter was standing, an unknown person with a key to her father's house was asking for several hundred pounds on the basis of some till receipts and her own account of an arrangement.
⚠ ⚠ ⚠ ⚠ She said no.
⚠ She was right to say no. That is the part Bea took longest to accept, and it is the part that matters.
What Bea Had Actually Been Doing
⚠ Bea thought she had been running errands.
She had not.
⚠ Bea had been extending unsecured credit to a stranger, on the strength of a friendly arrangement that existed only in her own memory.
⚠ ⚠ Every Wednesday she had made an unsecured loan of forty or fifty pounds to an eighty-four-year-old man, on no security, with no agreement, repayable at his convenience.
⚠ ⚠ ⚠ For four months he repaid it. That was not because the system worked. That was because he was well.
⚠ ⚠ ⚠ ⚠ The system had never worked. It had simply never been tested.
And underneath the money there was a second thing, which was in some ways worse: Bea had been letting herself into a vulnerable man's house, buying goods in his name, collecting a prescription with his details, and taking decisions about substitutions — none of which anybody had ever authorised her to do in a way that could be shown to a third party.
⚠ ⚠ ⚠ She had been acting as his agent without being his agent.
Why This Trade Is Different
⚠ Most small local trades involve doing something to a thing, or for a person, in exchange for money.
You mow the lawn. You clean the windows. You walk the dog. The work is visible, the boundary is obvious, and the money moves once, in one direction, at the end.
⚠ ⚠ Errand-running is not like that, and the difference is the whole book.
⚠ ⚠ ⚠ In this trade you spend somebody else's money, in somebody else's name, on things they have not seen, while they are not there.
That is a genuinely unusual position for a sole trader to be in. It is closer to what a bookkeeper or an attorney does than to what a cleaner does. It carries the same exposures — money, authority, records, trust — and almost nobody entering the trade recognises that, because the surface of the work looks so ordinary.
⚠ ⚠ ⚠ ⚠ Picking up a prescription looks like a favour. It is a controlled item collected in another person's name from a regulated business.
⚠ ⚠ ⚠ ⚠ Doing somebody's shopping looks like a kindness. It is a purchase made as an undisclosed agent with funds that belong to a third party.
⚠ ⚠ ⚠ Returning a parcel to a shop looks trivial. It is a transaction in somebody's name that may produce a refund to an account that is not yours.
None of that means the work is dangerous or that you should not do it. It means the work needs a system that ordinary local trades do not need, and the people who fail at it are not the unreliable ones. They are the reliable ones who never wrote anything down.
The Two Failure Modes
⚠ In eleven years of this trade, the serious failures come in exactly two shapes.
⚠ ⚠ The first: you spent money that was not yours to spend, and you cannot get it back.
The float. The card in your own name. The "settle up at the end of the month." The client who is slow. The client who dies. The client who moves into care. The client whose family arrives and does not recognise you. The client who genuinely believes they already paid you.
⚠ ⚠ ⚠ The second: you did something in somebody's name that you were not authorised to do.
Signed for a delivery. Accepted a substitution they did not want. Collected medication for somebody who was not entitled to have you collect it. Bought alcohol on behalf of a person you never saw. Returned an item and accepted a credit note instead of a refund. Let yourself into a house after the arrangement had ended.
⚠ ⚠ ⚠ ⚠ Everything else — a late arrival, a wrong brand, a bruised avocado — is an inconvenience. These two are business-ending.
The Four Rules
Everything in this book comes out of those two failure modes. There are four rules, and every chapter is one of them applied to a specific situation.
⚠ Rule 1: You never spend your own money.
Not as a preference. Not usually. Never. The moment your card, your cash, or your credit funds a client's purchase, you have converted a service business into a lending business, and you are very bad at lending because you have no agreement, no security, and no recovery process.
⚠ ⚠ Chapter 4 is the whole argument.
⚠ Rule 2: You are not their agent.
You carry out defined tasks. You do not represent them, decide for them, sign for them, or speak for them. Where a task genuinely requires acting in somebody's name — collections, returns, prescriptions — it requires specific, written, dated authorisation for that specific task, and there are tasks where no authorisation you can obtain is sufficient.
⚠ ⚠ Chapter 5, and then Chapters 17, 19, and 20 in detail.
⚠ Rule 3: Every task has an end.
A task is a written instruction with a defined finish. "While you're there, could you just —" is a new task. It gets written down and priced, or it does not happen. This sounds petty and is the difference between a business and an unpaid obligation that grows every week.
⚠ ⚠ Chapter 6.
⚠ Rule 4: The receipt is the job.
The errand is not the deliverable. The record is. You spent somebody's money on something they did not watch you buy, and the only thing standing between you and an argument you cannot win is a complete, timestamped, reconciled record that a stranger could read.
⚠ ⚠ Chapter 7, and then Chapters 22 and 23.
What Success Looks Like
⚠ Most people in this trade measure the wrong things.
They measure whether the client was happy. Whether the errands got done. Whether the diary is full. Whether the reviews are good.
Bea's diary was full. Her clients were delighted. Her reviews, had she asked for any, would have been excellent. Right up until the Wednesday it wasn't.
⚠ Every task was authorised in writing before it started, funded by somebody other than you, and closed with a receipt that reconciles.
⚠ ⚠ Three numbers, checked at the same time every week:
⚠ ⚠ ⚠ Tasks carried out without written authorisation. Target: zero.
⚠ ⚠ ⚠ Spend that has not been reconciled to a receipt and a funding source. Target: zero.
⚠ ⚠ ⚠ Money you are personally owed. Target: zero.
⚠ ⚠ ⚠ ⚠ If all three are zero, you can lose a client without losing anything else. If any of them is not zero, you are carrying a risk you have not priced.
Chapter 26 builds the weekly close that produces these three numbers in about ten minutes. Chapter 36 tracks them over time. Resource 37 is the sheet.
Where AI Fits, and Where It Does Not
⚠ This is an AI-powered business book, and it is worth being precise about what that means here, because the honest answer is narrower than the marketing.
⚠ ⚠ AI is very good at the writing you will otherwise not do.
Task briefs. Authorisation wording. Client policies. The message that explains a substitution. The complaint response you need to send while angry. The service menu you have been meaning to write for eight months. Route planning drafts. Pricing scenarios. The eleven questions to ask an insurer. Practice conversations for refusals you find difficult.
That is genuinely valuable, because the paperwork is exactly what people in this trade skip, and the paperwork is exactly what would have saved Bea.
⚠ ⚠ ⚠ AI is not a source of truth about your obligations.
⚠ ⚠ ⚠ ⚠ It does not know whether your motor insurance covers carrying goods for reward in your area, whether a pharmacy will release medication to you, what age-restriction rules apply at the till, whether you can accept a refund on somebody's behalf, or what your tax position is on money that passes through your hands.
⚠ ⚠ ⚠ It will answer all of those questions fluently and it may be wrong, and the consequence of the wrong answer lands on you, not on it.
⚠ ⚠ ⚠ ⚠ Every rule, requirement, and limit in this business comes from a named human source, obtained by you, written down with the date you obtained it.
⚠ ⚠ ⚠ Resource 3 is where those go. Chapter 37 is the full discipline.
How the Book Is Built
⚠ Thirty-seven chapters in five parts.
Part One — Getting Started (Chapters 1–7). What the trade actually is, what people buy, the business models, what this work is not, and then one chapter per rule.
Part Two — Setting Up (Chapters 8–16). Refusals, credibility, the service menu, niche, market research, the plan, the money, the name, and the legal, insurance, and vehicle footing.
Part Three — Doing the Work (Chapters 17–26). Authorisation, payment mechanisms, restricted items, prescriptions, routes, chain of custody, records and reconciliation, privacy, safeguarding, and the weekly close. This is the operational heart of the book.
Part Four — Pricing and Operations (Chapters 27–32). Packages, prices, agreements, partnerships, communication, and procedures.
Part Five — Clients, Money, and Growth (Chapters 33–37). First ten clients, marketing, complaints, money tracking, and responsible AI use.
⚠ ⚠ Every chapter ends the same way: How AI Helps, Common Mistakes, Safety and Legal Considerations, Do This Now, and a Chapter Summary.
⚠ ⚠ ⚠ Four prompts per chapter. One hundred and forty-eight in total, all repeated in the library at the end.
⚠ ⚠ ⚠ Sixty-eight resources across six parts: forms, registers, logs, protocols, worksheets, and templates. They are referenced by number throughout, and every one of them is cited in a Do This Now list somewhere in the book.
What This Book Will Not Give You
⚠ ⚠ It names no shop, chain, pharmacy, courier, platform, app, payment provider, bank, or insurer.
⚠ ⚠ It states no law, no licensing requirement, no insurance position, no vehicle regulation, no age-restriction threshold, no data-protection rule, and no tax obligation.
⚠ ⚠ ⚠ This matters more here than in most trades. Whether you may carry goods for reward, collect a prescription, buy age-restricted goods for another adult, hold a client's funds, or keep a key to somebody's house are all questions with real answers that differ by country and change over time.
⚠ ⚠ ⚠ ⚠ Every one of those answers comes from your insurer, your accountant, your local authority, the pharmacy, the retailer, or the platform — obtained by you, dated by you, and written into Resource 3.
⚠ ⚠ Every figure in this book is in U.S. dollars, and every figure is blank.
⚠ ⚠ ⚠ There are no rates here. Not a suggested hourly figure, not a mileage rate, not a package price. Chapters 14 and 28 show you how to calculate yours from your own numbers, which is the only price that means anything.
A Note on the Warning Markers
⚠ The ⚠ marks throughout this book are load-bearing.
⚠ ⚠ They mark places where getting it wrong costs somebody real money, real medication, real privacy, real safety, or costs you the ability to keep trading.
⚠ ⚠ ⚠ They are not emphasis and they are not decoration. Where you see one, slow down.
About Bea
⚠ Bea is a composite, assembled from the way this trade actually goes wrong.
⚠ ⚠ They are not a real person. No real client, family, household, shop, pharmacy, or organisation is named anywhere in this book.
⚠ ⚠ ⚠ The three hundred and forty pounds is not a real debt. It is the shape of a real debt, which several thousand people are carrying right now without a piece of paper that would let them collect it.
Before You Start
⚠ If you are already running errands for money, do one thing before you read Chapter 1.
⚠ ⚠ Add up what you are currently owed. Every float you are carrying, every "settle up next week," every receipt in the glovebox that nobody has paid you back for.
⚠ ⚠ ⚠ Then, for each amount, ask whether you have a document that a stranger — a daughter, an executor, a small claims clerk — would accept as evidence that the money was authorised.
⚠ ⚠ ⚠ ⚠ Whatever that total is, it is the number this book is about.
