E-signature replaced paper for a reason: faster close, auditable trail, no printing or scanning. The useful work is picking the right tool, understanding the legal boundaries, and integrating signing into the sales motion.
An e-signature, or electronic signature, is any electronic method of signing a document that signals legal intent and authentication. It carries the same legal weight as a handwritten signature under US ESIGN Act, EU eIDAS, and most equivalent laws. Common examples include typing a name into a signature box, drawing a signature with a mouse or finger, or clicking an "I agree" button. Specialized tools like DocuSign and PandaDoc add audit trails, witness logs, and advanced identity verification.
Six things to understand about e-signatures: what qualifies, the legal frameworks, the difference from digital signatures, common use cases, how to pick a tool, and the limits.
An e-signature is any electronic representation of a signature that signals intent to agree to the document. Typing a name, drawing a signature, clicking "I agree," attaching an image of a signature all qualify under most laws. The key is intent plus authentication, not the specific format.
US ESIGN Act (2000) and state UETA laws make e-signatures legally equivalent to handwritten signatures for most contracts. EU eIDAS Regulation does the same across the EU and distinguishes simple, advanced, and qualified e-signatures. Canada PIPEDA, UK Electronic Communications Act, and Australia Electronic Transactions Act are the regional equivalents.
A digital signature is a specific type of e-signature using public-key cryptography (PKI) to verify identity and prevent tampering. All digital signatures are e-signatures. Not all e-signatures are digital signatures. For most commercial contracts, a simple e-signature is sufficient. For high-stakes documents, digital signatures or qualified e-signatures add rigor.
B2B use cases are everywhere a signature historically slowed the deal. MSAs, order forms, NDAs, SOWs, employment agreements, approval forms, HR paperwork. Enterprise sales motions that moved to e-signature typically see close time drop 2 to 5 business days per deal.
The dominant platforms are DocuSign (largest, enterprise-grade), PandaDoc (strong in SMB and mid-market, document-focused), Dropbox Sign (lightweight, developer-friendly API), and Adobe Acrobat Sign (bundled with the Adobe ecosystem). Each offers audit trails, templates, bulk send, and integrations. Strkr integrates with DocuSign and PandaDoc; it does not build native e-signature.
E-signature laws exclude certain documents: wills, codicils, trusts in some jurisdictions, divorce decrees, adoption papers, court orders. Real estate transactions in a few jurisdictions still require specific notary processes. For most B2B contracts (SaaS, services, procurement), e-signature is fully valid.
EU eIDAS defines three tiers of e-signature with increasing rigor. US ESIGN does not explicitly tier them, but mature programs apply the same framework. The right tier depends on the document and the counterparty.
A simple electronic signature is any electronic method of signing: typing a name, drawing with a mouse, clicking an agreement box, attaching a signature image. Valid for most commercial contracts. The audit trail of the signing session (IP, timestamp, document hash) provides the authentication.
An advanced e-signature is uniquely linked to the signer, capable of identifying them, created with controls under their sole use, and tamper-evident (any post-signing change invalidates the signature). Public-key cryptography is the common implementation. Required for some regulated contracts (healthcare, finance).
A qualified e-signature meets AdES requirements plus certified identity verification from an EU-approved Trust Service Provider. Legal equivalent of a handwritten signature in all EU member states for all documents. Required for some notarial acts, specific banking contracts, and public-sector documents.
Most B2B SaaS contracts, order forms, NDAs, and services agreements run on simple e-signature with full legal weight. Regulated-industry contracts (medical research, pharmaceutical, financial advisory) may require advanced. Qualified e-signature is for specific government-recognized use cases.
US ESIGN and state UETA laws accept simple e-signatures for almost all commercial contracts without tiering. EU eIDAS pushes more documents toward AdES or QES by regulation. Global contracts should match the strictest applicable jurisdiction. Most enterprise platforms support all three tiers.
The legal validity of a signature depends on the audit trail: who signed, when, from what IP, with what identity verification. Platforms that generate robust audit certificates survive disputes better than ad-hoc email signatures. Keep the signed document and audit trail together for the statute-of-limitations period.
The win from e-signature is not just the signature itself. It is the shorter cycle from "deal verbally closed" to "revenue booked." Four patterns pull the most time out of the cycle.
Pre-built templates with merge fields (customer name, pricing, terms) let a rep send a contract in minutes, not hours. Legal reviews the template once. Reps use it hundreds of times. The time save compounds. Mature programs template every common deal shape.
The best setup lets a rep click "Send contract" from the deal in the CRM, auto-fill the template from the deal data, and track signature status next to the deal stage. No copying data between systems. No manual signature-status updates. Strkr integrates with DocuSign and PandaDoc at the deal level.
Multi-party documents (MSA + order form, SOW with internal approver) need signature order. Platforms let you set the sequence: customer counter-sign, then internal legal, then CEO. The workflow enforces the sequence so you never end up with signed documents waiting on an upstream approval.
A contract sits in the signer inbox for a week. Automated reminders at day 2, day 5, day 10 recover 20 to 30 percent of lapsed signatures without a rep follow-up. Set the cadence once, every contract benefits.
After the final signature, the platform generates an audit certificate: who signed, when, from what IP, with what verification, how long on each page. The certificate attaches to the signed document and travels with it. Essential for any downstream dispute or compliance audit.
For NDAs, renewal forms, consent paperwork, bulk send lets you send the same document to hundreds of recipients with per-recipient fields. The savings versus one-at-a-time workflow are significant. Common at scale events, partner recruitment, and annual compliance refreshes.
Four patterns cause most e-signature pain. Each is avoidable with 30 minutes of setup. The common theme is treating e-signature as a thin wrapper around email rather than a managed workflow.
Reps draft each contract from scratch, legal reviews each one, delays stack. The fix is pre-approved templates with merge fields and a short list of permitted redlines. Legal reviews the template once per quarter, not every deal.
Customer signs the order form. Then the rep remembers legal and the CFO need to counter-sign. The deal sits for a week. The fix is multi-party routing baked into the template, with the sequence enforced before the first send.
Ad-hoc signatures over email, scanned PDFs, retyped names: all legally valid, all terrible under dispute. The audit trail is the point of using a platform. Keep the signed document and audit certificate together in the CRM record.
A pharmaceutical research contract signed with a simple e-signature may not survive FDA audit. A real estate transaction may need jurisdiction-specific notary. Match the signature tier to the regulatory requirement. For general B2B SaaS, simple is almost always sufficient.
Strkr integrates with DocuSign and PandaDoc so you can send contracts from the deal record and track signature status next to the pipeline stage. The audit trail travels with the deal.
An e-signature is any electronic method of signing a document that signals legal intent and authentication. Common forms include typing a name, drawing with a mouse or finger, clicking an "I agree" button, or applying a saved signature image. E-signatures carry the same legal weight as handwritten signatures under ESIGN, UETA, and eIDAS.
Yes, for almost all commercial contracts. In the US, the ESIGN Act (2000) and state UETA laws establish e-signatures as legally equivalent to handwritten signatures. The EU eIDAS Regulation does the same across the EU. A small set of documents (wills, codicils in some jurisdictions, specific court filings) still require wet ink.
E-signature is the general category: any electronic method of signing with intent. Digital signature is a specific type that uses public-key cryptography (PKI) to verify identity and prevent tampering. All digital signatures are e-signatures. For most commercial contracts, a simple e-signature is sufficient.
eIDAS is the EU Electronic Identification, Authentication and Trust Services regulation that governs e-signatures across member states. It defines three tiers: simple (SES), advanced (AdES), and qualified (QES). QES is legally equivalent to a handwritten signature in all EU member states for all document types.
DocuSign is the largest and most enterprise-ready. PandaDoc excels in SMB and mid-market with document-focused workflows. Dropbox Sign offers a developer-friendly API. Adobe Acrobat Sign is bundled with the Adobe ecosystem. For B2B SaaS sales motions, DocuSign and PandaDoc are the most common choices.
Almost all. The exceptions vary by jurisdiction: wills, codicils, some trusts, divorce decrees, adoption papers, and specific court orders typically still require handwritten signatures. For all standard B2B contracts (SaaS, services, order forms, NDAs, MSAs, SOWs), e-signatures are fully valid.
Strkr does not build native e-signature. It integrates with DocuSign and PandaDoc at the deal and document record level, so contracts can be sent, tracked, and attached to the deal without leaving the CRM. The integration path keeps the audit trail intact and shortens close time.
