The Price Is Agreed Once. The Work Changes Fifty Times.
Most owners can price work properly. They know their costs, they know their margin, and the number that goes out is a fair one. The trouble is that the work they priced and the work they end up delivering are rarely the same work.
Everything moves after the price is fixed
The scope gets revised. The timeline slips because someone upstream was late. A client asks for something to be done differently in a review, and the team does it, because stopping to raise a change over something small feels petty and slows everyone down.
That instinct is not a failing. Being easy to work with is usually why a business gets asked back, and plenty of good businesses are built on exactly that reputation. But the commercial consequence still lands, whether or not anyone intended it.
The margin does not go in one place
When a piece of work comes in well under the quoted margin, owners tend to look for a single cause: the price was too keen, or one bad month ate the schedule. It is almost never that.
It is twenty or thirty small pieces of work that were carried out and never priced as changes. Individually none of them looked worth the paperwork. Together they are the difference between the margin that was quoted and the margin that was banked. The gap between what you quoted and what you actually kept covers the wider version of this problem.
This is not a sector problem. It shows up in a software company absorbing feature requests between sprints exactly as it does in an engineering firm absorbing extra scope mid-project. The vocabulary changes. The commercial mechanism does not.
Why it cannot be recovered afterwards
The reason this is worth attention now rather than later is simple. A change is straightforward to price on the day it happens, when everyone remembers the conversation and the work has not been done yet. It becomes almost impossible to price six months later, once the work is delivered, the people have moved on and there is nothing in writing.
At that point you are not negotiating. You are asking a client to voluntarily pay for something they already have. That conversation rarely goes well, and it is the one that damages the relationship, not the change that was raised politely at the time.
This is commercial management, not legal work
The fix is not a solicitor and it is not a heavier contract. It is a habit that costs minutes: every change gets written down, priced and acknowledged before anyone starts it. An email confirming what was asked for and what it will cost is enough for most of it.
It matters if you are ever selling the business, because a buyer reads a delivery history full of unpriced changes as a business that does not control its own commercial position. It matters just as much if you never sell, because it is your money either way. The same discipline sits behind knowing how much of your income really sits with one customer.
Start with the last piece of work
You do not need a system to begin. Take the last piece of work you completed and list what was delivered that was not in the original scope. Then check how much of it was ever priced. Most owners find the gap is wider than they expected, and the pattern is usually the same on the work they are running right now.
