Electronic signature for communications agencies
Quotes, purchase orders, service contracts, confidentiality agreements with advertisers, subcontracting agreements with freelancers, and copyright assignments: have all the documents that shape the life of a creative or media agency signed in just a few minutes. Compliant with the Commercial Code, the Intellectual Property Code, eIDAS regulation, and Article 1366 of the Civil Code.
Use cases in a communications 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. Recorded acceptance constitutes contract formation (article 1101 of the Civil Code) and prevents any dispute over the order placed — 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.
Framework agreement & supplier agreement
Annual framework agreements with recurring advertisers, supplier agreements with large account procurement departments: multi-signatory signatures (communications director, procurement, 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 keep the sales cycle moving.
Freelance subcontracting agreement
Brief, deliverables, deadlines and intellectual property rights assignment clauses (article L131-2 of the Intellectual Property Code) signed before work starts. Dual-channel OTP formally identifies each independent contractor.
Copyright assignment
Separate assignments of reproduction, distribution, and adaptation rights: Certyneo's advanced electronic signature (AES) satisfies the written requirement of article L131-3 of the IPC and traces express mention of each right assigned.
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 POs 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 overwhelming production managers.
Mobile signature without account creation
Your advertisers and freelancers sign from their phone in less than 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 anytime 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 each 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 POs
Under French law, a quote signed by a client constitutes contract formation (article 1101 of the Civil Code): acceptance binds both parties on price, scope and timelines. Advanced electronic signature guarantees that acceptance is attributable to an identified person and that the document has not been modified after signature.
Certyneo delivers for each signed quote or PO an audit certificate embedded in the PDF, which groups together all technical evidence:
- Signatory identity (verified email, phone number confirmed by OTP)
- Qualified timestamp of acceptance — date that can be invoked against any late dispute
- SHA-256 hash of the quote as presented, which demonstrates the absence of subsequent modification
- Access log (how many times the client opened the quote before signing)
- IP and rough geolocation of the signatory at the time of acceptance
This body of evidence prevents typical disputes ("the quote had been modified", "I never received this version", "the PO is not mine") and secures amicable recovery as well as litigation before the commercial court.
Copyrights, GDPR and professional confidentiality
An agency handles sensitive data (confidential briefs, original creations, advertiser contacts) that require a strict compliance framework.
Rights assignment — Intellectual Property Code
Articles L131-2 and L131-3 of the IPC require written documentation that specifically mentions each right assigned (reproduction, distribution, adaptation), territory and duration. Certyneo's advanced electronic signature satisfies the written requirement and traces the creator''s express acceptance.
Commercial Code — invoicing & POs
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 POs with their audit trail, accessible at any time for tax audits.
GDPR — advertiser and freelance data
100% EU hosting (IONOS Germany), no transfer outside the EU, TLS 1.3 encryption in transit and AES-256 at rest, standard DPA available. Compliant with GDPR obligations for processing personal data of advertiser contacts and independent freelancers.
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 metadata audit trail is viewable on the platform side.
Frequently asked questions from agencies
Does an electronically signed quote legally bind the client?
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 constitutes a firm order. Certyneo's advanced electronic signature, compliant with Article 1367 of the Civil Code, formally identifies the signatory 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 client (email, name, amount), upload your quote template, and the platform generates 50 or 200 envelopes in a single operation. Each recipient receives their personalized link and signs on mobile without creating an account.
Are copyright assignments signed online enforceable?
Yes, provided the assignment is express, written, and specifically mentions each right transferred, the territory and duration (article L131-3 of the CPI). Certyneo's advanced electronic signature satisfies the writing 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 less than 2 minutes before a meeting?
Yes. You upload 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 from the signatory's side, ideal before a creative pitch.
Does Certyneo integrate with HubSpot, Pipedrive or our project management tool?
Yes, via native Zapier and Make connectors and our webhooks. You can automatically trigger the creation of a Certyneo envelope upon validation of a HubSpot quote, or record the return signature in an Asana / Notion / Monday project. Our REST API is documented for custom integrations.
How long are purchase orders and contracts archived?
Our plans include 10-year archiving with probative value, which covers commercial limitation periods (article L110-4 of the Commercial Code) and the obligation to retain purchase orders (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) imposes 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 signing by freelancers who have neither a professional email address nor KBIS?
No constraints on Certyneo's side: the signatory provides their personal email and phone number, the dual-channel OTP formally identifies the natural person. The freelancer's legal status (sole proprietor, individual enterprise, SASU) has no impact on the value of the signature — Article 1366 of the Civil Code applies to any identifiable natural person.
