Automate Rental Agreements

The problem

Property managers send lease agreements, tenancy contracts, and rental renewals for every unit. Each agreement has different terms, dates, and tenant details. Managing paper or PDF signatures across a portfolio is time-consuming.

The solution

Generate lease agreements from your property management data and send for signing via API. Tenants sign on their phone, and both parties get a certified copy immediately.

What you need to know

Rental agreement automation solves one of property management's biggest operational headaches: getting lease documents signed efficiently across a portfolio. Whether you manage 5 units or 500, every lease involves the same process — customise terms, send for signing, chase the signature, file the copy.

The property management document cycle: New tenancies require lease agreements. Annual renewals require new signatures. Rent increases require amendment letters. Move-outs require deposit return documentation. Each creates a paperwork burden that scales linearly with portfolio size.

Dynamic lease generation: Every property has different terms — different rent, different deposit amounts, different permitted uses, different maintenance responsibilities. API-driven generation pulls these details from your property management system and produces a customised lease without manual editing.

Remote signing for modern tenancies: Post-pandemic, tenants expect to complete lease signing digitally. Many tenants are relocating from different cities and can't visit the property office. Mobile-friendly signing lets tenants complete the process from anywhere, on any device.

Renewal automation: The highest-value automation for property managers is renewal processing. When a lease approaches its end date, automatically generate a renewal offer with updated terms (rent adjustment, new end date) and send for signing. This reduces vacancy periods and administrative workload simultaneously.

Compliance: In many jurisdictions, landlords must provide specific disclosures (lead paint, mould, flood risk, energy performance certificates) as part of the lease. Automating these ensures compliance across all properties, regardless of which property manager handles the tenancy.

Example document template

# Residential Lease Agreement

**Landlord:** {{landlordName}}
**Tenant:** {{tenantName}}

## Property
{{propertyAddress}}

## Terms
- Monthly rent: {{monthlyRent}}
- Lease period: {{startDate}} to {{endDate}}
- Security deposit: {{depositAmount}}

## Conditions
{{leaseConditions}}

Replace the {{variables}} with your application data and send via API.

Send it with one API call

curl -X POST https://signb.ee/api/send \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "YOUR_RENDERED_MARKDOWN",
    "senderName": "Your Name",
    "senderEmail": "you@company.com",
    "recipientName": "Recipient Name",
    "recipientEmail": "recipient@email.com"
  }'

Why this approach works

• Sign leases remotely — no in-person meetings required
• Dynamic terms for different properties and tenants
• Certified audit trail for disputes
• Manage renewals programmatically
