Electronic contract signing — from template to digital signature and archiving
Create contracts from templates, send for online signing, and store with full legal validity. Integrates directly with the CRM pipeline to accelerate deal closure.
- OTP SMS electronic signature — compliant with Decree 130/2018/NĐ-CP, no USB token or app required
- Mobile-friendly public signing page at /sign/{token} — no account needed for signatories
- Sequential multi-party signing — each party signs in order before the next is notified
- Upload PDF/DOCX templates — the system auto-detects {{variables}} and populates data from CRM Deal
- Append-only audit trail: IP, timestamp, user_agent — immutable once written
- Signed PDF with embedded legal evidence — downloadable at any time
- Signed contracts cannot be cancelled — only addenda can be created for amendments
- Auto-generated contract numbers in HD-2026-XXXX format
Challenges you're facing
Print → sign by hand → scan → email back and forth — a process that takes 3–7 days and loses impatient customers
Send a signing link in seconds; the customer signs on their phone via OTP SMS — the entire process completes in under 30 minutes
No visibility into where a contract sits in the process — who has it, who's signed, who hasn't
Contract dashboard shows each party's signing status in real time. Automatic reminders are sent to parties who haven't signed yet.
No legally admissible evidence in case of a dispute — scanned signatures aren't legally recognized
Every signing action is written to an immutable audit trail: IP address, timestamp, device. The signed PDF embeds all of this evidence.
Filling in contract details is time-consuming and prone to errors — wrong names, amounts, or dates
The system auto-fills variables from the CRM Deal: customer name, address, contract value, start date — just review before sending
Key features
Built for modern businesses — no complex setup, ready to use immediately.
Contract Templates
Upload PDF / DOCX
Upload your existing contract template. Supports both PDF and DOCX. The system automatically scans and identifies all {{variable_name}} placeholders.
Auto-Detect Variables
No manual configuration needed. The system lists every {{variable}} found and lets you map each to a field in CRM.
Template Library
Save and manage multiple templates: service agreements, lease contracts, addenda, and NDAs — reuse any template at any time.
Create & Send Contracts
3-Step Visual Workflow
Step 1: Choose a template. Step 2: Confirm variables from the CRM Deal. Step 3: Configure signatories and signing order. Send in one click.
Auto-Fill from CRM Deal
Company name, representative, address, contract value, effective date — all pulled from the Deal automatically. Just review before sending.
Auto-Generated Contract Numbers
Unique contract numbers generated automatically in HD-2026-XXXX format — no duplicates, no manual tracking.
Signing Process
Sequential Multi-Party Signing
Configure signing order: Party A signs first, then the system sends a link to Party B automatically once A completes. Easily add or remove parties.
OTP SMS Signing — No App Required
The signatory receives a link via SMS, opens it on their phone, reads the contract, enters an OTP to confirm identity, and signs — no app, no USB token.
Public Signing Page
A /sign/{token} URL for parties outside your system. Mobile-optimized, displaying the full contract before any action is taken.
Legal Validity & Storage
Immutable Audit Trail
Every action (open, sign, decline) is logged with IP address, millisecond-precise timestamp, and user agent. Append-only — can never be altered or deleted.
PDF with Embedded Evidence
The final PDF embeds the complete audit trail in its metadata. Open in any PDF reader to see the full authentication record.
Automatic Reminders
The system automatically sends reminders via email/SMS to parties who haven't signed after X days. Configure the number of reminders and frequency.
Contract Management
Status Dashboard
View all contracts: Drafting / Awaiting Signatures / Signed / Expired / Has Addendum. Search by name, contract number, or customer.
Amendment Addenda
Signed contracts cannot be cancelled. When changes are needed, create an amendment addendum — which also goes through the full signing process.

“Our customers are scattered across the country — signing contracts used to take a week because we had to mail documents back and forth. Now we send a link and the customer signs on their phone the same day. Deal cycle dropped from 7 days to 1.”
