Intervention Order
with Electronic Signature

Date and time of intervention, technician and company identification, client identification, detailed description of work performed, parts and supplies used (references, quantities), time spent, observations on the condition of the installation, client signature confirming completion. For tradespeople: mandatory disclosures required by consumer protection law.

Yes, the signed intervention order constitutes proof that the work was completed. It serves as evidence in case of dispute. It triggers the client's payment obligation and engages the company's contractual liability for the work performed. In case of defective work, it is the reference document. It is recommended to keep intervention orders for 10 years (civil statute of limitations).

In many jurisdictions, a quote is required for work exceeding a certain threshold. For emergency repairs, the professional must at minimum inform the client of the price before intervening. An accepted quote constitutes a contract. Exception: maintenance contracts generally provide for intervention conditions without a prior quote.

The intervention order is an operational document describing the work performed, signed on site. The invoice is a mandatory accounting and tax document issued after the intervention, with specific legal requirements: invoice number, VAT, payment terms. The intervention order can serve as the basis for invoicing but does not legally replace it.

Under commercial law, accounting documents must be kept for 10 years. For construction warranty purposes, keep for 10 years after acceptance. For equipment warranties, keep for 2 years. In practice, keep all orders for at least 10 years. Digital orders have the same value as paper if integrity is guaranteed (electronic signature, timestamping).
