The obligations most likely to slip through the net are often the everyday ones.
Keep reading whenever you get five quiet minutes to see where these obligations most often go wrong in practice.
Based on our recent experience across a range of clients we take a clear view on this. Most contract problems do not start with the big headline clauses. They start with the obligations the team assumes are being handled, but often are not.
Price, liability and programme matter. Of course they do. But in live delivery, weaker performance usually shows up somewhere else. It shows up in notices, change control, payment conditions and reporting discipline.
For public sector contracts, this is particularly timely. Further provisions of the Procurement Act 2023 came into effect during 2026, bringing greater transparency around areas including supplier performance and payment. The wider commercial lesson applies well beyond public procurement. Obligations cannot simply sit in the contract. They need ownership, evidence and active management.
That is why we suggest paying close attention to obligations that look routine. They are the clauses people often skim past in negotiation and regret later in delivery.
If your team misses the notice window, the right is gone. That is not just paperwork as the commercial value is lost.
This is where projects drift fastest. People agree work in meetings, delivery moves on, and the contract record never catches up. We see this in projects across numerous sectors and this can be rectified with good process, discipline, clear communication and records. In fact we have found the key point is “records, records and more records”.
Performance regimes are often negotiated with considerable attention and then managed with much less discipline.
That is where value leakage can begin.
This has become even more visible in public procurement. From January 2026, the Procurement Act’s contract performance provisions require contracting authorities, where the relevant KPI requirements apply, to assess supplier performance and publish specified performance information at least annually and on termination.
Whether or not your contract falls within those requirements, the principle is useful: if performance matters commercially, it needs to be measured and actively managed.
Payment often depends on the right evidence, format or milestone sign-off. Teams need to get that right consistently because cashflow depends on it.
There may also be contractual and legislative requirements governing payment processes and timings.
Again, 2026 has sharpened the focus for public procurement. New Procurement Act requirements have increased transparency around payment performance. Separate requirements applying to certain procurements commenced from 1 April 2026 require information about individual payments over £30,000 including VAT to be published quarterly.
The first publication deadline for that new contract payment information regime fell in July 2026.
Payment administration is therefore increasingly not just a back-office process. It is part of visible contract governance.
Teams often see issues early and raise them late. That delay turns manageable risk into a harder commercial position.
We see this dismissed as admin far too often. It is not admin. It is how you keep visibility and control.
These obligations are easy to forget once the contract is live. They typically matter most when the pressure is already on.
If you accept obligations upstream and fail to mirror them downstream, the risk stays with you. That is a basic control failure, so attention needs to be given upstream and downstream within the supply chain.
These clauses tend to be negotiated late and embedded badly. They become very real when there is a breach, a handover issue or a dispute over ownership.
Too many teams treat exit as a future problem. In our experience this is a mistake to overlook this or put this off. Exit planning should start long before the contract ends.
We have seen a project team agree extra work in good faith, start delivery straight away and leave the change paperwork until later.
The work got done. The payment argument came later. By then, the baseline was blurred and both sides thought they were right.
That issue was avoidable and not only tainted the relationship but cost both parties more than the cost of doing it right in the first place.
So here is the trade-off. You can keep things light and trust the team to work it out as they go. That feels quicker. It also creates ambiguity, weakens leverage and stores up avoidable disputes.
Or you can treat obligation management as part of delivery from day one. That takes more discipline with clear processes and responsibilities that need to be followed consistently. It also gives you cleaner decisions, stronger evidence and fewer surprises.
Our view is straightforward. If an obligation affects entitlement, payment, risk or control, it should be managed actively or risk the consequence later.
