Why sign a quotation electronically
Getting a quotation signed is transforming a proposal into an order. The faster it happens, the warmer the prospect remains. Electronic signature allows you to move from "I'll think about it" to "approved and signed" in 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. Quick, 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 mobile or computer
- Signed quotation automatically returns to your CRM and accounting
"Approved" mention
Traditionally, the handwritten mention "Approved" was required before the signature. In electronic signature, clicking "I sign" with OTP provides the same consent, legally equivalent.
You can nonetheless integrate a "Approved" text field in the electronic quotation to reassure clients accustomed to paper.
Operational benefits
- Sales staff freed from manual follow-up
- Fewer "forgotten" or lost quotations
- Impressive responsiveness for the prospect
- Direct feed into invoicing (accounting gain)
Common mistakes
- Not including Terms & Conditions in annex
- Using AES for a simple quotation (over-dimensioned, unnecessary friction)
- Forgetting payment terms
- Not setting up automatic reminders
Real case: industrial SME
An industrial SME sent 150 quotations/month by email. Paper signature rate: 40%, average delay 8 days. Switch to electronic signature:
- signature rate: 62%
- average delay: 2.5 days
- estimated annual commercial gain: +€180,000 additional revenue
