The situation
A German customer’s supply contract and purchasing terms, uploaded
A component maker in Brno has been offered a five-year supply contract by a car-parts group in Stuttgart. The contract chooses German law and attaches the customer’s 22-page purchasing terms: payment at 120 days, unlimited supplier liability, a unilateral right to cut prices each year. The client’s sales director wants to know by Monday which clauses are worth a fight.
Reading the contract is not the slow part. The time goes on testing each clause against the rules the parties cannot contract out of: the control of standard terms, transparency, the late-payment rules. Then on writing it up as a list the client can take into the negotiation, weakest clauses first.
What the research has to settle
The rules behind the answer
- Name the law you are testing against
- Under the Rome I Regulation the parties may choose the governing law, and its mandatory rules then apply in full. Had the contract chosen Czech law, the Czech Civil Code’s split between mandatory and default provisions and its rules on adhesion contracts would be the test instead.
- Standard terms face content control
- German law reviews pre-formulated terms even between businesses. A term that unreasonably disadvantages the other party contrary to good faith is ineffective. Whether a clause was individually negotiated, and so escapes that review, is a question of fact the list should flag.
- Transparency is a test of its own
- Under German law a standard term can be ineffective simply because it is not clear and comprehensible. Annual price-reduction and rebate clauses in purchasing terms are typical candidates.
- Payment terms beyond 60 days
- Under the Late Payment Directive, payment periods between businesses longer than 60 days are allowed only if expressly agreed and not grossly unfair to the creditor. National law implements the rule and may be stricter, and the research confirms how Germany applies it to standard terms.

From the question to the document
The question, as you would type it
Attached: supply contract under German law between a Czech supplier and a German buyer, with the buyer’s purchasing terms. Which clauses are likely ineffective under the German rules on standard terms, in particular the 120-day payment term, the unlimited liability clause and the annual price reduction?

Supply contract with the Stuttgart customer: clauses to negotiate
Payment term, clause 7. The 120-day period sits in the customer’s standard terms, not in a negotiated clause. A term of this length is open to challenge, and we recommend proposing 60 days with a reasoned fallback.
Price reduction, clause 11. The customer may lower prices each year without stated criteria. A clause of this kind can fail for lack of transparency as well as on its content. We suggest tying any reduction to agreed cost drivers.
Liability, clause 14. The clause makes you liable without limit for all losses, including those you could not foresee. This is the clause with most at stake commercially. We propose a cap tied to annual contract value, with the usual exceptions for intent and personal injury.

Frequently asked questions
- Does azta mark up the contract itself?
- No. It reads the uploaded contract, researches the rules and drafts the issues list and redrafts. You make the changes in your own document.
- Can it review against a law other than the one chosen?
- Yes. Name the law in your question. azta researches the mandatory rules of that law and cites them, so you can compare outcomes under each.
- Is the uploaded contract kept confidential?
- Client documents are never used for training on any plan, and they stay in the EU/EEA.
