Terms and Conditions

of SiSy Solutions GmbH


The relevant legal basis for all orders and contracts concluded by us (contractors) are the German Civil Code and the following terms and conditions. They are already agreed for all future business relationships and their priority over differing conditions of the client is stipulated. If our conditions are changed, they apply from the time they are first received by the customer. We do not recognize any conditions of the client that deviate from our terms and conditions, unless we have expressly agreed to their validity. There are no side agreements. We reserve the right to supply you with orders from abroad through our sales partners.

Offer and design documents

The property rights and copyrights to cost estimates, programs, drawings, programs and drafts prepared by the contractor as well as their arithmetic bases must be observed. The client must provide the contractor with all the documents necessary for the provision of the work / service and provide the information and information required for the provision of the service. All offers are binding for the contractor for 21 working days.


All prices apply only in the case of an undivided commissioning of the offered service and for uninterrupted service provision with subsequent commissioning / handover. Services not expressly quoted in the offer, which are necessary for the execution of the order or which are carried out at the request of the client, will be invoiced additionally. Deviations are also permitted if the contractor incurs additional expenses from breaches of duty by the client or if such expenses were not recognizable despite sufficient care. If the additional expenses that are necessary to perform the agreed work exceed the originally agreed scope of services by more than 5%, the contractor can exercise his right to terminate the contract. This applies mutatis mutandis if services are required that the contractor cannot provide. The prices apply 3 months from the conclusion of the contract. In the event of a longer delivery period for which the contractor is not responsible, the then valid prices apply. If the start, progress or completion of the work is delayed for reasons for which the contractor is not responsible, he is entitled to the extent that no agreement is reached with the client within two months of the contractor's request to negotiate Immediately stop work and invoice the services provided. The contractor reserves the right to bill the client for any additional costs and downtimes. Surcharges are calculated and charged for overtime, night, Sunday and public holiday hours as well as work under difficult conditions.


Unless otherwise agreed, all payments are due net within 10 days after the invoice has been issued. The deduction of a discount requires prior written agreement. A default occurs without a reminder. Payments are to be made in cash, without any deduction, free of charge to the contractor's payment office in euros. If the terms of payment are not adhered to or if circumstances become known that seriously question the client's creditworthiness or if a check is not cashed, all outstanding claims become due immediately. After the unsuccessful expiry of a reasonable grace period set by the contractor, the contractor is entitled to terminate the contract in writing and to cease the work and to invoice all previously performed services according to contract prices. Furthermore, the contractor reserves the right to assign his claims to third parties. If the client is in default of payment, we are entitled to demand default interest of 5% above the respective base rate of the Deutsche Bundesbank (according to ยง 247 BGB).

Delivery time and assembly

If execution deadlines have not been agreed, work must begin immediately after the order has been confirmed, but no later than twelve working days after being requested by the client, provided that the client has provided the necessary documents, an unhindered start of work is guaranteed and any agreed down payment has been received by the contractor. If we are in default for reasons for which we are responsible, liability for damages in the event of slight negligence is excluded. If we fall into arrears, our liability for damages in the case of slight negligence is limited to the adequate damage. The replacement of unforeseeable damage requires evidence of intentional or similar
