What Leverage Actually Is
Leverage is the ability to make something happen at a cost you are willing to pay. For a small supplier it is almost entirely spent before the work starts.
Yourswho controls this stretch
What can actually be done at each point, and what it costs
Ask for a deposit, or decline the work
Costs you: The work, if they say no — and sometimes the relationship
Refuse to start without a purchase order
Costs you: Two weeks of delay while it is raised, and the look it earns you
Stop at a milestone that has not been paid
Costs you: The job, the reference, and the argument about who breached
Send it the same day, to the right address, with the order number on it
Costs you: Nothing at all, which is why this is the only free move on the list
Ring accounts payable and ask where it is
Costs you: Twenty minutes, and the small cost of being the supplier who chases
Charge statutory interest
Costs you: Almost always the next order, whatever the law says you may do
Six moves, and exactly one of them is free. Every other lever is paid for in work, in time, or in the relationship — which is what having no leverage means in practice. One supplier's own list, not advice about what to do.
Leverage is the ability to change what somebody else does, at a cost you are willing to bear. A small supplier facing a large customer has some at the start, less once the work begins, and almost none once the invoice has been sent.
The commercial boundary in “What Leverage Actually Is” is clearer when estimated work, recorded time and authorised scope can be compared. For teams researching hybrid remote meaning, see the corresponding product overview can add that operational context, but purchase terms and payment obligations should remain in the signed agreement.
That curve is the subject of this whole collection, and most of what goes wrong is a decision taken late that could only have been taken early.

Before you agree
The widest moment. You can decline, ask for a deposit, set terms, ask who raises the order, check whether they pay anybody on time.
Nothing has been spent, nothing is owed, and refusing costs only the work itself.
Once you have agreed
Narrower. The price is set, the terms are set, and anything you did not ask for you are not going to get.
What remains is the order, the evidence and the milestones — real levers, but each already shaped by what was agreed.
Once the work is done
Very little. The thing they wanted, they have. The only genuine move left is to be correct: the right document, to the right place, with the right reference, on the right day.
That move is free, which makes it the most valuable one on the list.
Once the invoice is sent
None, in the sense that matters. You can ask, you can ask again, you can escalate, you can charge interest, you can sue.
Each is available and each has a price, and the prices rise much faster than the chances of being paid any sooner.
Why the curve is shaped this way
Because leverage comes from being able to withhold something the other side wants, and after delivery you are not holding anything.
This is not a complaint about large buyers. It is the arithmetic of the position.
What people do instead
Spend the leverage they have left at the point of greatest frustration, which is month three. By then the only levers available are the expensive ones.
The same energy applied in week one, as a question about the order, would have changed the outcome.
The question worth asking early
Who inside your organisation raises the order, and who approves the invoice? Asked before agreeing, it is a normal commercial question.
Asked in month three, it is an accusation.
The cost that is never counted
Your attention. An unpaid invoice occupies a disproportionate amount of a small supplier's week, and none of that time is billable to anybody.
Counting it changes which battles look worth having.
What this collection is not
Advice about what to do in any particular case. What may be charged, what interest may be claimed and what remedies exist differ by place and by contract.
It is an account of where the leverage sits, so that it can be spent while it still exists.
How the same curve looks from inside the buyer
Nothing about this is malice, and seeing it from the other side explains why appeals rarely work. Before the order exists, a buyer has a decision to make and a supplier it wants; your terms are one item in a negotiation it would like to conclude. After the order exists, the decision has been made and the work is a commitment already recorded. Once the invoice arrives, the buyer's own staff have no discretion at all: the document enters a process built to pay what matches and to hold what does not.
The person you have been dealing with has, at that point, roughly the same amount of control over your money as you do. This is why a friendly contact can be sincerely sympathetic and completely useless, and why suppliers who read that sympathy as influence wait an extra month before asking somebody who can actually act.
The part of the curve nobody uses
The flat stretch between agreeing and starting is where almost nothing happens and almost everything is still possible. An order can be chased, a reference confirmed, onboarding completed, the invoice address established and the approval route identified — all before a single hour of chargeable work exists.
Suppliers skip it because it feels like administration rather than progress, and because the customer is not asking for it. Then the work is delivered, the invoice is sent, and the onboarding form arrives afterwards with nine days of its own.
Those days were available for free and were spent at the worst possible moment. Doing them early is the single cheapest change available in this whole collection, and it costs an afternoon.
The one sentence version
Almost everything that decides whether you are paid on time happens before any work is done, and almost nothing after the invoice is sent is free.
