- Multi-signer sequential (3 signers): Autenti 3–7 days median completion in sample workflows; Dropbox Sign 2–6 days. Automated reminders, embedded signing and signer verification affect outcomes.
Migration and integration guidance
Migration checklist (Autenti ⇄ Dropbox Sign)
- Export templates and audit logs from source platform.
- Map fields and merge tags between systems; confirm date, initial and signature anchors.
- Transfer signer roles and recipient groups.
- Recreate conditional logic and workflow triggers.
- Validate legal metadata (audit trail, certificate chain) after migration.
API and integration examples
- Dropbox Sign quick API call (curl) to create a signature request:
curl -u "API_KEY:" https://api.hellosign.com/v3/signature_request/send /
-F "title=Purchase Agreement" /
-F "subject=Please sign" /
-F "message=Sign this document" /
-F "signers[0][email_address][email protected]" /
-F "signers[0][name]=Buyer" /
-F "file[]=@/path/to/agreement.pdf"
- Autenti API: many Autenti customers use RESTful endpoints to create offers, set signer authentication and fetch a certified audit trail. Refer to the vendor portal for enterprise API details: Autenti.
Common integrations
- CRM (Salesforce, HubSpot): map signed documents to account records and trigger follow-up workflows.
- Document management (SharePoint, Google Drive, Dropbox): automate storage and retention.
- RPA / automation (Zapier, Make/Make.com): connect signature events to billing, user provisioning or records updates.
Industry use cases and vertical recommendations
Real estate and property conveyancing
- Requirement: high evidentiary standards; qualified signatures often required for final deeds.
- Recommendation: Autenti where EU-certified trust services are needed; Dropbox Sign for preliminary agreements and negotiation stages.
HR and onboarding
- Common need: rapid signing, template reuse, bulk sending.
- Recommendation: Dropbox Sign for fast template management and integrations with HRIS; Autenti where candidate/employee identity verification must meet eIDAS levels.

FAQ
What is the main legal difference between Autenti and Dropbox Sign for UK/EU use?
Autenti emphasises EU-focused signatures with options aligning to eIDAS levels; Dropbox Sign covers widely accepted commercial e-signatures and developer-friendly APIs. For qualified signatures, a certified trust service provider is required under eIDAS. See the regulation: eIDAS regulation.
Can Dropbox Sign be used for documents requiring qualified electronic signatures?
Dropbox Sign supports advanced signature workflows but typically relies on third-party qualified trust services for fully qualified electronic signatures. Enterprises should contract for qualified signature support explicitly.
How does data residency differ between the two vendors?
Autenti commonly offers EU-located processing and storage. Dropbox Sign uses global infrastructure; EU-only residency is usually available on enterprise contracts but requires confirmation in the data processing agreement.
Dropbox Sign has more established connectors (Zapier, Make) and broader third-party ecosystem support. Autenti supports integrations but may require custom API work for complex automations.
Include direct license fees, API call costs, storage costs, professional services for migration, and internal change management. Create scenarios for low, medium and high signature volumes and include expected savings from reduced cycle time.
Are audit trails tamper-evident and admissible in court?
Both vendors produce audit trails; admissibility depends on signature level, certificate chain, and legal context. For the highest assurance, use qualified signatures and retain signed package and verification metadata.
Is BYOK or HSM support available?
BYOK / HSM support is often part of enterprise agreements. Request explicit clauses and proof of HSM (FIPS 140-2/3) implementation if key custody is a compliance requirement.
What are common migration pitfalls?
Field mapping mismatches, missing conditional logic, lost signer metadata, and insufficient validation of audit evidence. A dry-run migration with legal review of retained signed packages is recommended.
Competitive gaps and recommended procurement questions
- Ask vendors for sample signed packages showing audit trails and certificate chains.
- Request pen test reports and SOC 2/ISO certificates.
- Confirm exact pricing per API call, per user and per template for expected volumes.
- Verify SLAs for uptime and support response times.
Conclusion
Decision criteria must prioritise the organisation’s legal exposure, integration needs and required signing speed. For EU-centric, regulation-sensitive workflows and data residency, Autenti often provides closer alignment with eIDAS-focused requirements. For rapid integrations, broader marketplace connectors and developer convenience, Dropbox Sign typically accelerates automation and developer adoption. Procurement should request sample evidence, run a migration pilot, and calculate TCO over a 3-year horizon before finalising the vendor.
