The agreement gets negotiated over six weeks, marked up three times, signed, and filed. For most businesses that is the last time anybody reads it.
Not through carelessness. The people who negotiated it move on to the next thing, and the people who have to live with it were never in the room. The contract becomes a document, when what it actually is, is a set of instructions.
What the lawyer was asked to do, and what they were not
A good commercial lawyer protects you from the things that would hurt most if the relationship goes wrong. Liability, termination, what happens in a dispute, who owns what. That is the mandate, they are trained for it, and it is worth paying for.
Nobody asked them what your business has to do on the fifteenth of every month for the deal to work as intended. That was never their job. It is rarely anybody else's either.
The clauses that only pay if somebody works them
A good deal of what you negotiated is money you then have to go and collect.
An escalation clause permitting an annual increase does nothing unless somebody applies it, on time, against the right index. A volume rebate is claimed, not credited automatically. Interest on late payment is a right rather than an event. A milestone payment falls due when somebody raises the invoice that says it has.
Every one of those was argued for in the negotiation. Every one of them is worth nothing sitting in a folder.
The clauses that only bite if somebody misses them
The other half runs the opposite way.
Notice periods expire quietly, and an agreement you intended to renegotiate rolls over on the old terms for another year. Exclusivity you granted in year one blocks a customer you want in year three. A minimum volume commitment nobody is tracking becomes a shortfall payment nobody forecast. A covenant in a facility gets breached on a technicality months before anyone notices, which is the worst possible way for a lender to find out.
None of these announce themselves. They arrive as a letter.
The version everybody is working from
Ask three people what the payment terms are on your largest customer and you will often get three answers: what the sales lead agreed, what the system was set up with, and what the customer actually pays. Only one of those is in the contract, and it is frequently not the one being used.
That is not a filing problem. It means the terms you negotiated are not the terms you are operating on, and nobody has spotted it because each version is plausible on its own.
What a signed contract is supposed to turn into
In a business that runs its agreements properly, a signed contract does not stay a contract. It turns into other things.
A date in a diary, set months ahead of the last day for giving notice. A payment term in the system that matches the one on the page rather than the one somebody assumed. A line in the forecast for the volume you committed to and the money that follows it. A monthly check on any number you have promised somebody else you will stay inside.
That translation is the work. It is not legal work and it is not administration. It is the commercial reading of what you have signed.
Why it falls between two stools
The lawyer's mandate ended at signature. Operations never saw the document, and would not have known which parts mattered. Finance is usually told the headline value and the payment terms, and nothing else.
So the obligations sit in a folder and the business runs on what everybody remembers of the negotiation, which is not the same thing as what was signed.
A test worth running on your three largest agreements
Take the three biggest, by value or by how much you depend on them.
When does each one renew, and what is the last date you can give notice? What are you entitled to increase or claim this year, and has anybody claimed it? What have you committed to that you are not currently measuring? Does the payment term in your system match the payment term in the document?
If any of those four takes more than an afternoon to answer, the agreements are not being operated. They are being stored.
The commercial half of a legal document
None of this is an argument for spending less on lawyers, or for reading contracts as though you were one. It is an argument that a signed agreement has two halves.
The legal half is protection, and it belongs with people who do that for a living. The commercial half is a set of obligations, entitlements, and dates that somebody has to run, and it belongs to whoever owns the numbers. If nobody owns the second half, you are paying for protection you already have and losing money on terms you negotiated and never used.
