Self-Service E-Signatures with Part 11 Evidence Chains
How Solace brings OAuth3-backed electronic signatures and FDA Part 11 Architected evidence storage to every pricing tier.
The compliance gap nobody fills
FDA Part 11 Architected storage starts at $15,000 per year from the cheapest dedicated vendor. For most teams, that price locks compliance behind an enterprise gate.
Solace takes a different approach. Every e-signature is backed by an OAuth3 token, linked into a SHA-256 hash chain, and stored with ALCOA+ metadata. The architecture supports Part 11 requirements by design, not as an expensive add-on.
How it works
The signing flow is simple: request a token, choose password or drawing mode, select an attestation statement, sign. Behind the scenes, each signature gets a unique evidence hash that chains to the previous signature, creating a tamper-evident audit trail.
This is not a checkbox. It is a hash chain. If anyone changes a record, the chain breaks and the system flags it.
Pricing that makes compliance accessible
Every Solace tier includes e-signatures. Free users get 3 per month. The $28 Pro tier includes 100 signatures with 90-day Part 11 Architected retention. Enterprise at $188 per month gets unlimited everything.
That is 85 percent cheaper than the cheapest dedicated Part 11 storage vendor, and the evidence quality is higher because it is hash-chained rather than just timestamped.
