As of 28 Oct 2026, the panel rates Dropbox Sign 3/5 and Zoho Sign 2.5/5 in E-Signature. Weighted by what each judge cares about, 6 of the 6 judges pick Dropbox Sign and 0 pick Zoho Sign. Dropbox Sign scores higher on 5 of 7 criteria (Signer identification, eIDAS levels & trust services, Integrations & API, plus 2 more). Zoho Sign scores higher on 2 of 7 criteria (Signing workflow & signer experience and European sovereignty). Provenance — Dropbox Sign: Rest of world; Zoho Sign: Rest of world. Ratings are the AI panel’s opinion, formed from public evidence: how scores are made.
The benches split. Dropbox Sign holds the higher mean on five of seven criteria — signature levels 6.0 to 4.2, identity verification 6.0 to 2.8, evidence and retention 5.2 to 4.3, integration and API 7.0 to 5.5, pricing transparency 4.0 to 3.7 — and six judges lean its way on signature levels, identity verification and integration and API. Zoho Sign takes signing workflow 6.7 to 6.0 (four leans, two ties) and sovereignty 4.5 to 3.8 (five leans to one). Pricing transparency splits two leans to Dropbox Sign and four ties. Weighted totals favour Dropbox Sign on six of six judges, 5.2 to 6.0 against 3.8 to 5.3, yet the attributes list Zoho Sign's data residency as EU only and Dropbox Sign's as US default, while Dropbox Sign's pages name connectors, SDKs and an eID add-on and Zoho Sign's say identity is verified before a qualified signature without naming a method.

The Skeptic
Knows "legally binding" usually means a simple signature. Reads for the level the default plan actually signs at, the QTSP the provider does not operate itself, the per-QES and ident fees on top of the plan, the envelope limit, and "eIDAS-compliant" from a provider that names no trust service at all.

Zoho Sign
Criterion by criterion
eIDAS levels & trust services
Dropbox Sign
Advanced and qualified signatures are named as eIDAS levels and delivered through named providers — InfoCert as an EU QTSP, Swisscom stated as QES under ZertES, plus Belgian eID, Finnish eID, Danish Mit-ID and EvroTrust with their countries — which is more than a bare compliance claim. But the qualified route sits only on the Dropbox Sign API Premium plan as an add-on purchase, limited to one signer at a time, and we found no EU Trust List link, no qualified seals for company documents and no statement of which level appears in the signed file. The default service is marketed as legally binding under the ESIGN Act of 2000.
Zoho Sign
Qualified signatures are genuinely on offer — the homepage describes certificates issued by a qualified trust service provider after the signer's identity is verified, and the enterprise tier lists QES alongside 21 CFR Part 11 controls. But we found no public information naming the trust service provider or its trust-list entry, nor on simple and advanced levels, countries, ZertES or seals — a QES badge with no chain behind it.
Signer identification
Dropbox Sign
SMS verification codes are documented on the Standard and Premium API plans, and the eID methods are listed by name with their countries — EvroTrust even with a long list of accepted identity-document countries — with InfoCert named as the certificate issuer for some methods. We found no public information on reuse of an identification for later signatures, on what specifically happens to identification data afterwards beyond the general privacy policy, or on any of these methods outside the API Premium add-on.
Zoho Sign
The qualified-signing description says the signer's identity is checked, but we found no public information on how — no video ident, eID card or bank ident by name, no countries, and nothing on what happens to ID data. Recipient authentication and SMS delivery are the only concrete mechanisms named.
Signing workflow & signer experience
Dropbox Sign
Templates with signer roles and field placement, a gallery of over forty, bulk sending with per-signer reminder targeting, decline-to-sign, reassignment and variable signers are documented, and recipients sign without an account at no cost. The captured pages give no signing order, conditional fields, signer languages or accessibility statement, and signature requests requiring eID go to only one signer at a time and cannot be bulk-sent.
Zoho Sign
Templates, signing order, reminders, bulk sending, self-service SignForms, approval workflows, custom roles, branding and no-account signing with mobile and desktop apps are all documented — a solid core workflow. We found no public information on conditional fields, delegation or substitute signers, signer languages or accessibility.
Evidence, validation & retention
Dropbox Sign
A non-editable audit trail with timestamps and IP addresses is appended to executed requests, can be delivered as its own file, and carries an identifier Dropbox looks up in its own database plus a PDF hash comparison — validation that runs through the vendor, not an independent tool. We found no public information on PAdES long-term validation, qualified timestamps or a validation report; retention is stated only as long as necessary for the stated purposes, and the terms permit Dropbox to delete customer data at any time after 30 days from termination.
Zoho Sign
Audit trails, document timestamps and a blockchain timestamp feature are listed, and documents can be exported or deleted on request — but we found no public information on what the audit trail records, on qualified timestamps from a named provider, on long-term validation, or on a retention period for signed documents; the terms only promise deletion from the active database within six months of cancellation.
Integrations & API
Dropbox Sign
A documented API with endpoints, walkthroughs, SDK libraries, free test mode, embedded signing in an iFrame, text tags, events and callbacks and an embedded testing tool is evidenced, with Google Drive, HubSpot and Microsoft Word as named connectors and the is eid parameter exposing the qualified route through the API. We found no public information on a versioned API with published rate limits, or on connectors for DMS, ERP or HR systems.
Zoho Sign
A REST API for signing automation, webhooks, web and mobile SDKs, an API-only plan and white-label options are documented. Integrations are described only as Zoho apps and unnamed third-party apps — we found no public information naming Microsoft, Google, CRM or DMS connectors, nor on a sandbox or API versioning.
European sovereignty
Dropbox Sign
EU customers contract with Dropbox International Unlimited Company, a data processing agreement is published, and qualified signatures run through InfoCert, an EU trust service. But the terms expressly permit Dropbox and its subcontractors to transfer and store customer data in locations other than the customer's country, with Data Privacy Framework certification and standard contractual clauses as the transfer story, and the captured pages do not confirm where documents and audit trails reside — a 'Data residency' row on the pricing comparison carries no location detail.
Zoho Sign
The German homepage states data storage in an EU data centre, a Dutch entity in Utrecht is the data protection contact, and a DPA is available on request. The privacy policy however discloses processing in the USA, the EEA and other Zoho countries under standard contractual clauses, and we found no public information on the contracting entity's jurisdiction, ownership, named data centres or a subprocessor list.
Pricing transparency
Dropbox Sign
Only the Standard plan carries a price in the captures — €24 EUR per user per month, 'Starting at €576 EUR billed yearly' — with signature requests unlimited on Essentials, Standard and Premium but no figures captured for the other plans. The eID add-on that carries advanced and qualified signatures is bought by contacting your account manager or support, other add-ons are 'contact sales', the overage mechanism auto-upgrades you into a higher plan at non-refundable cost, and API pricing appears only as a pointer with no numbers.
Zoho Sign
Envelope limits per tier are public — five documents a month free, 25 per user on standard, unlimited on professional — plus a credit add-on at €0,10 apiece in increments of 500, a 20 % annual saving and taxes on top. We found no public information on the plan prices themselves, the per-signature cost of qualified signing, or identification fees; volume and OEM pricing are quote-only.
