Terms of use and estimates

1. Use of this website

This website is intended for businesses and professionals. By using it you agree to use it lawfully and not to interfere with its operation.

2. Online estimates are not offers

The online estimator produces an automatic, indicative figure from your answers and our standard effort model. It is not binding and does not constitute an offer or a contract. The actual scope, price and timeline are defined only in a written quotation issued after an engineer has reviewed your project, and they may differ significantly from the online estimate. The detailed breakdown we send by e-mail is also indicative until it is confirmed as a quotation.

3. Quotations

Written quotations state scope, deliverables, assumptions, price and schedule for each phase and are valid for 30 days unless stated otherwise. Prices are in euros excluding VAT. Work starts once the quotation is accepted in writing and the phase has been paid.

4. Summary of standard service conditions

  • Payment. Each phase is paid in full in advance. Work on a phase starts only when its payment has been received. Debugging is sold in prepaid blocks of hours. Hardware is invoiced when ordered.
  • Results. We are paid for the engineering work, not for a particular test outcome. Testing can show that a design, whether supplied by the client or by us, does not work as intended, and hardware can be damaged during tests. In that case the phase is delivered with its findings and the following phases are re-planned and re-quoted.
  • Communication. In writing, by e-mail or a shared chat channel. Decisions and approvals are valid in writing.
  • Changes. Changes of scope are agreed in writing with their effect on price and schedule before they are carried out.
  • Ownership. Intellectual property rights in the deliverables of each phase are assigned to the client on full payment of that phase. We retain our general know-how and pre-existing tools.
  • Confidentiality. Our NDA is signed before the client sends documentation.
  • Responsibility. We perform the work with professional care. Compliance of the final product with legal requirements, including CE marking, remains the responsibility of the manufacturer placing it on the market. Our liability is limited to the fees paid for the phase concerned, except in cases of wilful misconduct or gross negligence.
  • Law. Spanish law applies; courts of Barcelona.

The signed quotation and, where applicable, a framework agreement prevail over this summary.
