Terms &
Conditions

Last updated: 11 July 2026

These Terms & Conditions are an English translation of the original Dutch version ("Algemene voorwaarden"), provided for convenience. In case of any discrepancy, the Dutch version prevails and is governed by Dutch law.

Article 1 - Definitions

In these terms and conditions, the following definitions apply:

• Convolutio: the sole proprietorship/business Convolutio, based at Roode Steen 7, 1621 CV Hoorn, the Netherlands, registered with the Dutch Chamber of Commerce (KvK) under number 75851792, VAT identification number NL002375522B48.
• Client: the natural or legal person who instructs Convolutio to carry out work.
• Agreement: any arrangement between Convolutio and Client to carry out work, as recorded in a quote or written confirmation.
• Services: all services provided by Convolutio, including data management, software development, business automation, mobile applications and (advanced) websites.

Article 2 - Applicability

These terms apply to every quote, agreement and delivery by Convolutio, unless otherwise agreed in writing. Any purchasing or other terms of Client are explicitly rejected.

Article 3 - Quotes and formation of the agreement

All quotes from Convolutio are non-binding and valid for 30 days, unless stated otherwise. An agreement is formed at the moment Client accepts the quote in writing (including by email), or as soon as Convolutio begins work at Client's instruction.

Article 4 - Performance of the agreement

Convolutio will carry out the work to the best of its insight and ability. Stated timelines are indicative and never constitute a strict deadline, unless expressly agreed otherwise in writing. Client will provide, in a timely manner, all information and cooperation reasonably required for performance.

Article 5 - Changes and additional work

Changes to the original assignment, or work falling outside the agreed scope, will always be discussed with Client first and only carried out after Client's approval of the resulting adjustment to price and/or timeline.

Article 6 - Prices and payment

All stated prices exclude VAT, unless stated otherwise. Invoicing takes place in the installments agreed in the quote. Payment must be made within 14 days of the invoice date. If this term is exceeded, Client is in default by operation of law, and Convolutio is entitled to charge statutory commercial interest and reasonable collection costs.

Article 7 - Delivery and acceptance

A project is considered delivered as soon as Client has approved the work in writing, or, in the absence of a response, 14 days after Convolutio has given notice of completion. After delivery, a bug-fix period of at least 30 days applies, during which defects attributable to Convolutio are resolved free of charge.

Article 8 - Intellectual property

Upon full payment of the agreed price, all rights to the source code and project data developed specifically for Client transfer to Client, unless otherwise agreed in writing. Rights to any generic libraries, frameworks or tools used by Convolutio remain with their respective rights holders.

Article 9 - Warranty and liability

Convolutio will make every effort to carry out work carefully and in accordance with the agreed specifications. Convolutio's liability for damages arising from the agreement is limited to the amount invoiced for the relevant assignment, with a maximum of the amount paid out by Convolutio's liability insurance in the relevant case. Convolutio is never liable for indirect damages, including consequential damages and loss of profit.

Article 10 - Force majeure

Convolutio is not obliged to fulfil any obligation if prevented from doing so as a result of force majeure. Force majeure includes, among other things, disruptions at hosting providers or other third parties on whom Convolutio depends and over whom it cannot reasonably exercise control.

Article 11 - Confidentiality

Both parties are obliged to keep confidential all confidential information they have received from each other in connection with the agreement, even after termination of the agreement.

Article 12 - Termination and dissolution

Both parties may terminate the agreement in writing with immediate effect, subject to compensation for work carried out up to that point. Convolutio is entitled to dissolve the agreement with immediate effect if Client remains in default of payment even after being given notice.

Article 13 - Governing law and disputes

Dutch law applies to all agreements between Convolutio and Client. Disputes will be submitted to the competent court in the district where Convolutio is based, unless mandatory law provides otherwise.
