On paper, omissions (removing work from the scope) seem like simple arithmetic: you don't pay for work that isn't done. The reality is far more cynical. Clients often pay a 'phantom tax' on cancelled work, simply because they missed the fine print regarding 'loss of profit'.
The "Loss of Profit" Trap: Why Cancelling Costs Money
Here is the counter-intuitive truth: Cutting a high-cost item rarely equals a 1-to-1 saving. If you decide to remove that €10,000 bathroom renovation from the contract, you won't get €10,000 back.
Why? Because the contractor is contractually entitled to the profit they would have made. This is often buried in general terms and conditions (such as the UAV paragraph 35). The contractor has already incurred costs for:
- Planning and work preparation.
- Procurement risks and administration.
- The margin already booked into their annual revenue.
The result? A flat deduction of often 10%. You save on paper, but effectively pay for air.
Strategic Scoping: Protecting Your Budget
Smart clients don't wait for the final invoice. They negotiate omissions before the signature hits the paper.
1. The "100% Credit" Clause
During contract negotiations, demand that omissions, if notified in time (e.g., 4 weeks before start), are credited at 100%. Contractors often agree to this to close the deal, saving you thousands in 'administrative costs' later.
2. The Unit Price Strategy
Ensure your quote contains specified unit prices. If it reads "Tiling: €80 per m2", and you cut 10 meters, the debate is over: you get €800 back. Without unit prices, you are at the mercy of the contractor's "reasonableness".
3. The Timing Effect
Announce omissions the moment you have doubts. The closer to execution, the stronger the contractor's argument that costs have already been incurred. An email sent six weeks in advance is legally bulletproof.
Insider Tip: Use omissions as leverage. Need additional work (e.g., extra sockets)? Propose offsetting this against omissions (e.g., doing the painting yourself). This 'netting' often avoids the administrative surcharge on both items.
Conclusion: Manage Scope, Manage Wallet
Minderwerk (Omissions) is not an administrative detail; it is a negotiation tool. Those who wait passively pay the 'tuition tax'. Those who proactively manage unit prices and settlement terms control the final balance.
Frequently Asked Questions about Omissions (Less Work)
How much is refunded for omissions?
Rarely the full amount. Contractors often deduct 10% for lost profit and overhead, unless agreed otherwise.
Can I cancel work unilaterally?
Yes, clients can reduce scope, provided it is reasonable and doesn't make the project unfeasible.
How do I avoid price disputes?
Ensure specific unit prices are in the original quote. This locks in the value of each item for future settlement.
