The FINAP doctrine Three pillars
Built on the three things every signature actually needs.
Existing e-signature tools were built for desktop era American sales workflows. TrueMarke was engineered from the ground up for regulated finance, mobile-first markets, and signatures that have to hold up under legal scrutiny.
01
Timing
Real-time multi-party signing from any device - web and mobile. No more chasing courier copies across time zones or waiting on someone to find a scanner.
02
Trust
A four-layer evidence trail: OTP-verified identity, recorded legal consent, page-by-page review mandate, and SHA-256 cryptographic sealing all bundled into a court-ready Audit Certificate.
03
Liberation
100% digital. eIDAS-compliant. Immutably archived in WORM storage for 7 years. No paper. No couriers. No in-person witnesses. No third-party trust dependencies - every seal is yours.
THE SIGNING EXPERIENCE END TO END
A signing flow that holds up
every step is evidence.
Most platforms collect a signature and call it done. TrueMarke records seven legally-relevant events across two portals, and seals the entire chain into the final document.
1
SENDER
Upload & configure
Drag in a PDF, set signing order, add signatories, draw signature and evidence zones across the document.
2
DELIVERY
Secure Email Dispatch
Enterprise-grade email dispatch powered by SendGrid API with real-time delivery and open tracking.
3
SIGNATORY
Secure Access & Consent
Secure single-use tokenized link access. Signatories pass double-consent gates before the document is unlocked.
4
VERIFICATION
Evidence & Verification
Upload supporting identity documentation. Legally binding declarations, IP, device headers, and timestamps logged on signing.
5
SEAL
Sealed & archived
SHA-256 integrity hash verification, custom visual Audit Certificate, and secure cloud storage with WORM archiving for 7 years.

TRUST & SECURITY COMPLIANCE BY DESIGN
Engineered for documents that have to win in court.
Every architectural decision in TrueMarke exists to defend a document under legal scrutiny. Key industry compliance requirements are mapped to four mechanical guarantees inside the platform.
Uniquely linked to the signatory
Hashed single-use signing token per signatory. OTP identity verification on Growth tier and above. Email-authenticated re-download for any subsequent access.
Capable of identifying the signatory
Name, email, IP address, device fingerprint, geolocation, OTP verification result and consent answers — all captured and bound to the signing event.
Created under signatory's sole control
Signatory draws or uploads their own signature on their own device. Single-use link. No shared credentials. Session is private and dies after signing.
Any subsequent change detectable
SHA-256 integrity hash verification. Every finalized document compiles with a tamper-evident cryptographic fingerprint. Any byte changed post-signing immediately breaks the seal.

Common Questions FAQ
Everything you need to know.
Is a WhatsApp signature legally binding?
Yes. TrueMarke uses WhatsApp as a delivery and verification channel, but the signature itself is an eIDAS-compliant Advanced Electronic Signature (AES) cryptographically sealed into the PDF. The legal weight comes from the HSM-backed certificate and the multi-factor audit trail.
Do I need a WhatsApp Business account?
No. TrueMarke provides the Meta-verified delivery infrastructure. Your documents are sent via our official channel, though you can white-label the sender identity in our Enterprise plans.
What is "per-document" pricing?
Unlike our competitors who charge per user or per "envelope", we charge for the final signed document. You can have 1,000 users in your dashboard at no extra cost. You only pay for the documents you actually execute.
Where is my data stored?
We use Microsoft Azure. For our regional clients, we ensure data residency within your specified geography (e.g., USA, Europe, or Asia) to meet local regulatory requirements.
Can I integrate TrueMarke into my existing ERP/CRM?
Absolutely. We offer a robust REST API and webhooks that allow you to automate document generation, dispatch, and archival directly from your existing core systems.
What is a legally binding digital signature?
A legally binding digital signature is an electronic signature backed by identity verification, signer intent, cryptographic sealing, and a tamper-evident audit trail. TrueMarke produces Advanced Electronic Signatures designed for evidentiary use in regulated business.
Is TrueMark the same as TrueMarke?
Yes. TrueMarke is the official product name, and TrueMark is commonly used as a short form. Both refer to the same FINAP digital signature platform at truemarke.com.
How does TrueMarke compare to DocuSign?
TrueMarke uses per-document pricing instead of per-user envelope caps, includes WhatsApp-native delivery, and provides SHA-256 tamper protection with geolocated audit logs and long-term WORM archival for compliance-focused teams.
How do I verify a signed PDF?
Upload your sealed PDF to the TrueMarke Verify page. Our engine checks cryptographic integrity and confirms whether the document matches the original signed record in the secure registry.
Is an electronic signature valid in the US and EU?
Yes, when implemented correctly. TrueMarke supports evidentiary standards aligned with ESIGN and UETA in the US and eIDAS Advanced Electronic Signature requirements in the EU, depending on workflow configuration and jurisdiction.
Does TrueMarke support unlimited users with per-document pricing?
Yes. TrueMarke uses per-document pricing e-signature economics with unlimited users e-signature access on eligible plans—an e-signature no per-user fee model compared with seat-and-envelope platforms.
Can I choose data residency for USA, Europe, or Asia?
Yes. As an Azure e-signature platform, TrueMarke supports data residency electronic signature controls so you can keep records in USA, Europe, or Asia to meet local regulatory requirements.
Is TrueMarke a DocuSign or Adobe Sign alternative?
Teams evaluating DocuSign alternatives, Adobe Sign alternative, Adobe Acrobat Sign alternative, HelloSign alternative, Dropbox Sign alternative, PandaDoc alternative, SignNow alternative, or OneSpan alternative often compare evidence quality and pricing. TrueMarke is built as a court-ready digital signature option with WhatsApp-native delivery, SHA-256 seals, geolocated audit logs, and WORM archival.
What makes a digital signature audit trail court-ready?
A court admissible electronic signature needs identity verification, signer intent, multi-factor document signing controls, an electronic signature audit log, and tamper-evident sealing—typically via HSM digital signature certificates and X.509 certificate digital signature standards where configured.
