License & Terms

Last updated: September 2026.

Courtesy translation. The French version (Licence et conditions) prevails.

1. Purpose

These terms govern the use of the DyaPi service and the modules/connectors distributed by Aytechnet. They prevail over the general Terms for the clauses concerned (Terms 7.4).

2. Ownership

DyaPi and its components (code, interfaces, trademarks, documentation) remain the exclusive property of Aytechnet. No intellectual-property rights are transferred to the user.

3. Right of use

For the term of your subscription, Aytechnet grants you a personal, non-exclusive, non-transferable right of use, for your own needs. On expiry or termination, no right survives: you stop all use and remove the installed integration components (plugin, connector, API tokens).

4. Modules and connectors (dyapiconnect)

  • Open-source components: under the stated licence (failing that, GPL v3 or later);
  • proprietary components provided free of charge: use limited to your own needs, no redistribution or modification, no durability commitment.

Free use grants no warranty, support or maintenance, unless an expressly ordered and invoiced service.

5. Third-party software

DyaPi may embed third-party open-source software, owned by their authors and subject to their licences (GPL, MIT, Apache, BSD or equivalent), which you undertake to comply with.

6. Acceptable use

  • use the service for its purpose and in line with applicable law;
  • keep your credentials, secrets and API tokens confidential;
  • do not circumvent usage limits, quotas or security mechanisms;
  • do not impair the availability or integrity of the service.

7. Electronic invoicing

  • DyaPi's role: DyaPi is an intermediary operator, not an accredited platform. Your e-invoices are transmitted and received through the accredited platform you link to DyaPi (SuperPDP), on your own account, opened in your name and governed by that platform's terms; your issued and received invoices are kept there and remain accessible at any time. DyaPi adds Factur-X generation, automated issuing, a consolidated view, the transfer into your management software, status tracking and a journal of acts.
  • Your obligations: you remain solely responsible for your invoicing, tax and reporting obligations (in particular Articles 289 bis et seq. of the French Tax Code), for the legal timeline applicable to your company, for the accuracy of your invoices and seller identity, and for your company's registration in the e-invoicing directory. Aytechnet provides a tool, not tax or legal advice.
  • Conditions of automatic issuing: DyaPi transmits an invoice only if automatic issuing is enabled for the licence and the invoice is dated on or after the chosen start date, if your seller identity is complete, if the platform is linked and active, if the recipient has an active entry in the directory and if your credit allows it (§ 8). Otherwise the transmission is held and not counted; DyaPi informs you in your workspace, in your scheduled report and, depending on the cause, by email and by an event in your software. It is up to you to clear the cause or to send the invoice to your customer through any other channel, notably as a continuity measure accepted by the tax administration; DyaPi transmits the same invoice as soon as the cause is cleared (recipient not listed: re-checked daily for 180 days). Aytechnet cannot be held liable for the non-transmission of an invoice held for one of these causes after having informed you.
  • Reception: the reception of your supplier invoices is never blocked. Their detailed consultation in DyaPi and their transfer into your software are subject to credit (§ 8); the invoices remain accessible on your platform account. You remain responsible for processing them and for the statuses the regulation requires you to return (acceptance, refusal); a status posted directly on the platform prevails over any later decision in DyaPi.
  • Manual deposits: DyaPi detects the invoices you deposit directly on the platform and never issues them a second time. An invoice deposited by hand while an automatic transmission is in progress may nevertheless reach your customer twice; you refrain from depositing by hand the invoices whose automatic issuing is enabled.
  • Traceability: DyaPi keeps a journal of acts (generation, directory check, transmission, manual deposit noticed, statuses) and mirrors the main ones in your software. These traces can be returned to you at the end of the relationship.

8. Credits and usage-based billing

  • E-invoicing operations are counted in units: one unit per issued invoice accepted by the platform, one unit at the first detailed consultation of a received invoice. A held or rejected transmission is not counted; the list of received invoices and status tracking are free.
  • Your subscription includes a monthly allowance of units; prepaid packs, valid one year, complement it. Beyond, subscribed customers' units are billed in arrears at the current rate; an account with neither subscription nor credit has its issuing held (§ 7) while reception continues.
  • DyaPi alerts you at 80% of consumption; any transmission held for lack of credit is flagged in your workspace and in your scheduled report. Top-ups are made from your workspace; the balance is recomputed on receipt of payment.

9. Availability and liability

The service is provided under the service levels set out, where applicable, in the Quote and Schedule A of the Terms. Aytechnet's liability applies within the limits of Article 11 of the Terms.

10. Personal data

See the Privacy Policy and, for data processed on your behalf, the DPA (Schedule B of the Terms).

11. Governing law

These terms are governed by French law; any dispute is subject to the jurisdiction rules of Article 15 of the Terms. Aytechnet may amend these terms by notice or publication.
