Why sign a quotation electronically
Getting a quotation signed is transforming a proposal into an order. The faster it is, the warmer the prospect stays. Electronic signature allows you to move from "I'll think about it" to "approved and signed" in just a few minutes.
Concrete benefits:
- shortened sales cycle (1-3 days instead of 7-15)
- improved conversion rate (+15 to 30% depending on sectors)
- traceability of agreement (exact date, IP, identification)
Recommended level
Simple electronic signature (SES) is sufficient for the majority of commercial quotations. Fast, frictionless, legally valid: once signed, the quotation is binding.
For high-value quotations (> €20,000) or regulated sectors, AES provides additional security.
Typical procedure
- Draft the quotation in your invoicing tool (Sellsy, QuickBooks, Sage…)
- Export to PDF
- Send via your signature platform, SES or AES
- Client signs from their mobile or computer
- Signed quotation automatically returns to your CRM and accounts
"Approved" mention
Traditionally, the handwritten mention "Approved" was required before signature. With electronic signature, clicking "I sign" with OTP provides the same consent, legally equivalent.
You can nevertheless integrate a "Approved" text field in the electronic quotation to reassure the client accustomed to paper.
Operational benefits
- Sales teams freed from manual follow-up
- Fewer "forgotten" or lost quotations
- Impressive responsiveness for the prospect
- Direct feeding of invoicing (accounting gain)
Common mistakes
- Not including Terms and Conditions in appendix
- Using AES for a simple quotation (over-dimensioned, unnecessary friction)
- Forgetting payment terms
- Not setting up automatic follow-ups
Real case: Industrial SME
An industrial SME was sending 150 quotations/month by email. Paper signature rate: 40%, average time 8 days. Switch to electronic signature:
- signature rate: 62%
- average time: 2.5 days
- estimated annual commercial gain: +€180,000 additional revenue
