Why e-signature tools are bleeding your budget

Per-envelope pricing, vendor lock-in, and limited customization are costing you more than you think.

Per-Envelope Pricing

Every signature costs money. High-volume teams pay thousands monthly for a commodity feature.

Vendor Lock-In

Your documents, templates, and audit trails are trapped in someone else's system.

Limited Customization

Generic workflows that don't match your industry's compliance or process requirements.

Per-Seat Licensing

Adding team members means adding costs. Growth becomes a budget conversation.

Compliance Gaps

Industry-specific requirements (HIPAA, real estate, legal) require expensive add-ons.

Data Sovereignty

Your sensitive documents live on third-party servers with limited control.

The average mid-size company spends $2,400/month on e-signature tools. That's $28,800/year for a feature you could own.

Own your e-signature workflow

A custom platform built for your exact needs. No per-envelope fees. No vendor lock-in.
