Electronic signature for communication agencies

Quotes, purchase orders, service agreements, confidentiality agreements with advertisers, subcontracting agreements with freelancers and copyright assignments: have all the documents that punctuate the life of a creative or media agency signed in minutes. Compliant with the Commercial Code, Intellectual Property Code, eIDAS regulation and article 1366 of the Civil Code.

Use cases in a communication agency

From advertiser brief to campaign delivery, all contractual documents of an agency can be signed online — including those that engage freelancers and media providers.

Client quote

Have each quote signed before production starts. The traced acceptance constitutes contract formation (article 1101 of the Civil Code) and prevents any dispute over the committed order — useful in Q3-Q4 when quote volumes explode.

Purchase order (PO)

Issue and have supplier POs signed (media buy, printing, post-production) with qualified timestamping. The audit trail certifies the order date, which secures invoicing under article L441-1 of the Commercial Code.

Master agreement & listing agreement

Annual master agreements with recurring advertisers, listing agreements with major account purchasing departments: multi-signer signatures (corporate communications, purchasing, legal) coordinated in a single envelope, 10-year archiving.

Creative brief NDA

Before the first presentation to a prospect, the confidentiality agreement protects your concepts. Electronic signature in less than 2 minutes on mobile to avoid slowing down the sales cycle.

Freelance subcontracting agreement

Brief, deliverables, deadlines and intellectual property rights assignment clauses (article L131-2 of the Intellectual Property Code) signed before project start. Dual-channel OTP formally identifies each independent contractor.

Copyright assignment

Separate assignments of reproduction, representation, adaptation rights: advanced electronic signature (AES) Certyneo satisfies the written requirement of article L131-3 of the IPC and records the express mention of each assigned right.

Why Certyneo for agencies

Six guarantees designed for agency constraints: high volumes, multi-stakeholder, strong seasonality and intellectual property.

Bulk sending for campaign peaks

Import 50 quotes or purchase orders at once from a CSV, each envelope is sent with its signatories and template — capacity designed to absorb back-to-school and Q4 weeks without overloading production managers.

Mobile signature without account creation

Your advertisers and freelancers sign from their phone in under 2 minutes, without downloading an app or creating an account. Observed conversion rate: 90% of signatures within 24 hours on quotes.

Audit trail admissible in court

Each envelope produces a signature certificate embedded in the PDF: timestamps, IP, OTP, SHA-256 hashes. Admissible before commercial courts in case of dispute over an order or rights assignment.

10-year archiving with probative value

Duration aligned with commercial statute of limitations (article L110-4 of the Commercial Code) and minimum retention period for purchase orders. Download at any time for tax audits or advertiser audits.

eIDAS compliant — advanced level (AES)

Signatures compliant with regulation (EU) no. 910/2014, recognized throughout the EU. Ideal for agencies working with European advertisers (Benelux, Germany, Spain) — the same certificate is valid in every jurisdiction.

API & agency workflow integrations

Webhooks, Zapier and Make to connect Certyneo to your CRM (HubSpot, Pipedrive), your project management tool (Asana, Notion, Monday) or your creative ERP (Workamajig, Boost). Automatic envelope creation from a validated quote.

Probative value of signed quotes and purchase orders

Under French law, a quote signed by a customer constitutes contract formation (article 1101 of the Civil Code): acceptance binds both parties on price, scope and deadlines. Advanced electronic signature guarantees that acceptance is attributable to an identified person and that the document has not been modified after signing.

Certyneo delivers for each signed quote or purchase order an audit certificate embedded in the PDF, which brings together all technical evidence:

  • Signer identity (verified email, phone number confirmed by OTP)
  • Qualified timestamp of acceptance — date enforceable against any late dispute
  • SHA-256 hash of the quote as presented, which demonstrates the absence of subsequent modification
  • Consultation log (how many times the customer opened the quote before signing)
  • IP and rough geolocation of the signer at the time of acceptance

This body of evidence prevents common disputes ("the quote had been modified", "I never received this version", "the purchase order is not mine") and secures amicable recovery and litigation before the commercial court.

Droits d'auteur, GDPR et secret professionnel

An agency handles sensitive data (confidential briefs, original creations, advertiser contacts) that require strict compliance framework.

Rights assignment — Intellectual Property Code

Articles L131-2 and L131-3 of the IPC require written documentation distinctly mentioning each assigned right (reproduction, representation, adaptation), territory and duration. Certyneo''s advanced electronic signature satisfies the written requirement and records the creator''s express acceptance.

Commercial Code — invoicing & purchase orders

Article L441-1 requires retention of purchase orders and general terms for 10 years (article L123-22 of the Commercial Code). Certyneo automatically archives signed purchase orders with their audit trail, accessible at any time for tax inspections.

GDPR — données annonceurs et freelances

Hébergement 100 % UE (IONOS Allemagne), aucun transfert hors UE, chiffrement TLS 1.3 en transit et AES-256 au repos, DPA standard disponible. Conforme aux obligations GDPR pour le traitement des données personnelles des contacts annonceurs et des freelances indépendants.

Confidentiality of creative briefs

Advertiser briefs and creative proposals are encrypted and isolated by agency account. No Certyneo access to document contents (zero-knowledge on content), only the metadata audit trail is accessible on the platform side.

Frequently asked questions from agencies

Does an electronically signed quote legally bind the customer?

Yes, without any ambiguity. Article 1101 of the Civil Code defines a contract as an agreement of wills intended to create legal effects: an accepted quote is equivalent to a firm order. Certyneo''s advanced electronic signature, compliant with article 1367 of the Civil Code, formally identifies the signer and guarantees the integrity of the quote as accepted.

How to manage peaks in quotes and purchase orders in Q3-Q4?

Certyneo integrates bulk sending: prepare a CSV with one line per customer (email, name, amount), upload your quote template, and the platform generates 50 or 200 envelopes in one operation. Each recipient receives their personalized link and signs on mobile without creating an account.

Are online copyright assignments enforceable?

Yes, provided that the assignment is express, written, and distinctly mentions each assigned right, territory and duration (article L131-3 of the IPC). Certyneo''s advanced electronic signature satisfies the written requirement and identification of the creator. For high-value works, we recommend using the AES level (default on Certyneo) rather than SES.

Can you get an NDA signed in under 2 minutes before a meeting?

Yes. You load your NDA template, add the prospect contact''s email, and send. The contact receives a direct link, signs on their phone without creating an account, and the envelope comes back to you signed — typically in 30 seconds on the signer''s end, ideal before a creative pitch.

Does Certyneo integrate with HubSpot, Pipedrive or our project management tool?

Yes, via native Zapier connectors, Make and our webhooks. You can automatically trigger the creation of a Certyneo envelope when a HubSpot quote is validated, or record the returned signature in an Asana / Notion / Monday project. Our REST API is documented for custom integrations.

How long are BDCs and contracts archived?

Our plans include 10-year archiving with probative value, which covers commercial prescription (article L110-4 of the Commercial Code) and the obligation to retain BDCs (article L123-22). Documents and their audit trail remain downloadable at any time, including after agency account termination upon request.

Do European advertisers recognize our electronic signatures?

Yes. The eIDAS regulation (EU no. 910/2014) requires mutual recognition of electronic signatures between the 27 member states. An advanced signature (AES) issued from Certyneo (EU platform) has the same legal value in Germany, Belgium, Spain or Italy as in France.

How to manage the signature of freelancers who have neither a professional email address nor KBIS?

No constraint on the Certyneo side: the signatory provides their personal email and phone number, dual-channel OTP formally identifies the natural person. The legal status of the freelancer (sole trader, individual business, SASU) has no impact on the value of the signature — article 1366 of the Civil Code applies to any identifiable natural person.
