Every figure at the negotiating table has a source.
Every negotiation target is data-driven and traceable: we combine your contract with price drivers and the index, the supplier’s position and our negotiators’ experience. You can use the public tools for this here, free of charge.
- Your contract: your cleaning service provider announces an increase of 12.0%.
- Industry metric: the wage component accounts for 75% of the price (assumption).
- Price drivers and index: the agreed wage for 2027 rises by 1.8% (offer) to 13.3% (demand).
- Supplier’s position: can the supplier afford a reduction? Its financial statements, the market situation and your share of its revenue tell you.
- Benchmark for your negotiation: at most 10.0% instead of 12.0% can be justified. The supplier must provide evidence for 2.0 percentage points.
Example: commercial cleaning. The calculation is shown further down.
Five building blocks make every negotiation target traceable
Each building block answers one question before the negotiation. Together they produce the price we negotiate for you, and the reasoning behind it.
Price drivers
freely accessible
Which part of the price is really getting more expensive?
Wages, materials, energy and travel by category, each with its change and source.
Terms Index
freely accessible
How much will wages and prices rise in 2027?
Minimum wage, collective agreements, diesel and surcharges, every figure with its source, updated quarterly.
Contract and clauses
freely accessible
What does your contract allow?
The price adjustment clause, term and notice period determine your room for manoeuvre. We check every announcement against them.
Supplier’s position
as part of a mandate
Can the supplier afford a reduction?
Published financial statements, the market situation and your share of its revenue show how much room for manoeuvre the supplier has.
Our negotiators’ experience
as part of a mandate
What can be achieved at the table?
More than 25 years in senior procurement positions and more than 8,000 supplier meetings: we bring this experience to the table. We know which arguments work.
Your negotiation target
A plausible, reasoned price that your supplier can recalculate.
Example: commercial cleaning, justifiable at most10.0%instead of the 12.0% announced
Today we work with public collective agreements, indices and prices, with the documents from your mandate and with our negotiators’ experience. Benchmarks from client projects will be added from 2027, only aggregated from at least five companies, anonymised and with no way of tracing them back to clients or suppliers. We do not publish the prices of individual suppliers.

Cost Driver Tree
Before you negotiate: you can see for each category whether to resist an increase or reduce the price.
27 documented price drivers in 31 categories
24 of the 27 documented price drivers are rising by 2% or more; 3 are stable. For 11 others, there is no reliable public figure. Figures and sources are in the Cost Driver Tree. October 2026 edition, next update November 2026

Check a price increase
When your supplier asks for more: you calculate which part is justified and reply with figures.

justifiableat most 10.0%
Example, commercial cleaning: the supplier must provide evidence for 2.0 percentage points.

Price adjustment clause
When you sign or renew a contract: you agree that only the cost share is adjusted, both up and down.
Index+4.0%
Your price+2.4%
Example with a 60% wage component: if the whole price were adjusted, it would be +4.0%.
How data becomes a negotiation target
Worked example for commercial cleaning: the service provider announces 12.0%; the wage component accounts for 75% of the price (assumption).
