Signing and archiving properly
An unsigned document binds no one
A perfect contract sitting in your drafts is worth nothing until it's accepted. And the scanned signature emailed back, or the "fine by me" in a chat thread, are fragile: hard to date, to attribute, to prove. Electronic signature solves this — it timestamps, identifies the signer, and seals the document. In Europe, the eIDAS regulation gives it real legal value, with several levels (simple, advanced, qualified) depending on the stakes. For nearly all everyday commercial contracts, the advanced signature of a recognized service is more than enough.
Signing online isn't a modern gimmick: it turns a fragile verbal agreement into dated, enforceable proof.
Electronic signature tools
Several services cover everything from a simple quote to a sensitive contract:
| Need | Tools | Indicative price | For whom |
|---|---|---|---|
| Everyday signing, FR/EU market | Yousign | ~€9-40/month | eIDAS-compliant, simple, French-speaking |
| International standard | DocuSign, Adobe Acrobat Sign | ~€10-45/month | International clients, high volume |
| Proposals + integrated signing | PandaDoc, Qwilr | ~€20-50/month | Quotes and proposals signed online |
| Light / free to start | native PDF signature, HelloSign (Dropbox Sign) | free to paid | First contracts, small volume |
Practical rule: in France and Europe, Yousign is a safe, compliant default. If your sales proposals are already written in a dedicated tool, prefer a solution that merges proposal and signature (PandaDoc, Qwilr) to remove a step.
Archiving: the reflex everyone neglects
Signing isn't enough: you have to find the signed document two years later, in case of dispute or audit. That's where most entrepreneurs lose the game — the contract is somewhere, in an inbox or on a hard drive. Set up a single, organized vault:
- Structured cloud storage: Google Drive, Dropbox, OneDrive with a clear folder tree (clients / contracts / invoices / company).
- Digital safe: Digiposte, or the vaults built into business banks (Qonto, Shine) for durable legal documents.
- Backup: an offline copy or a second cloud for critical articles, contracts, and invoices.
The golden rule: every binding document must be dated, signed, and findable in thirty seconds.
How long should you keep documents?
Each type of document has a legal retention period, and discarding too early can cost you in an audit:
- Invoices and accounting records: generally 10 years.
- Commercial contracts: at least 5 years after the end of the relationship (longer for some).
- Corporate documents and articles: the lifetime of the company, sometimes beyond.
- Tax documents: generally at least 6 years.
These periods vary with the nature of the document; when in doubt, keep them longer, and confirm the sensitive ones with your accountant.
Automation so nothing gets left lying around
The real risk isn't the signature, it's the filing that never happens. No-code connectors (Zapier, Make) automate archiving: a document signed in Yousign lands automatically in the right Drive folder, an issued invoice files itself by client, a contract sends a renewal alert before its deadline. What isn't automated ends up forgotten.
Key takeaways
Electronic signature turns a fragile agreement into dated, enforceable proof; in Europe, eIDAS gives it value, and an advanced signature (Yousign, DocuSign) is enough for everyday use. But signing is pointless if you can't find the document: organize a single vault, back up the critical files, respect retention periods (often 10 years for accounting), and automate archiving. With documents signed and filed, you now need to protect another sensitive material: personal data.
