More than a signature, it’s Proof

Automated document prep

Ensuring that every form is executed correctly can be a massive headache. Potentially hundreds of applicable laws, policies and business rules required to complete your signer’s documents. Proof dramatically reduces operational overhead by automating away many of these complexities.

Integrated identity verification

Collecting proof of identity from customers is a critical prerequisite for many solar contracts. You need to confirm that the people signing the agreement are eligible for solar installation, whether they’re the rightful property owner and whether they qualify for government incentives. Proof verifies identity using a combination of: SMS authentication, credential analysis, knowledge-based authentication, biometric comparison and third-party database checks.

Customer-friendly technology

Proof takes potentially complex processes like identity verification and notarization and makes them accessible to everyone. This includes supporting a wide range of device types. Our identity verification process is unique because signers having trouble with automated identity checks are instantly routed to a trusted referee for resolution.

Tamper-proof audit trail

Protections against contract disputes or repudiation are particularly critical in the solar industry where leases, loans and PPAs are often securitized. With Proof, Signed documents have a comprehensive audit trail trail with timestamps, identity verification results, and details of the actions performed by the signer.

Deploy in days

Upgrading technology is hard with constrained budgets and limited IT resources. Proof makes the decision easy with no code and low code deployment solutions that are up-and-running in days. There’s no need to endure a long and painful implementation or compete for a place on IT’s development calendar. Plus, the intuitive and easy-to-use design makes it simple for teams to adopt with minimal training.
