SignThis vs Zoho Sign
A Zoho Sign alternative outside the Zoho suite

How SignThis and Zoho Sign differ
Envelopes per user, or documents per plan
Zoho Sign Standard includes 25 envelopes per user each month, and Professional removes the limit. SignThis Basic includes 6 documents a month for one person, Standard 120 documents a year and Professional 200 documents a year; unlimited sending, subject to fair use, starts with the Business Standard team plan. No SignThis individual plan includes as many documents a month as Zoho Sign Standard gives each user.
Inside the Zoho suite, or on its own
Zoho Sign works with other Zoho apps, and its pricing page describes automations across them. SignThis has no catalog of ready-made integrations; it connects to other software through its API, signed webhooks and MCP server, from Professional. If your records already live in Zoho, that connection may matter more than anything in the table.
Certificates and seals
Zoho Sign’s paid plans list advanced electronic signatures with AATL-enabled certificates, and Enterprise adds qualified electronic signatures and blockchain timestamping. SignThis seals each completed PDF with a digital signature and an RFC 3161 timestamp from DigiCert. Its seal certificate isn’t yet from an authority on Adobe’s trusted list, so Acrobat may show the seal’s signer as unknown while still showing whether the file changed.
Paying per envelope, or per plan
Zoho Sign sells an API plan at $0.50 an envelope with no commitment, and its Enterprise plan includes APIs and webhooks; envelopes sent through the API use credits. SignThis includes its API, signed webhooks and MCP server in Professional at $25 a month, and API sends count against the plan’s 200 documents a year.
Where Zoho Sign is the better choice
Zoho Sign does things SignThis doesn’t. It may suit you better if:
- You already use other Zoho apps and want signing to work inside them.
- You want a larger free plan: Zoho Sign’s includes 5 envelopes a month for a single user, and SignThis’s sends 3 documents a month.
- You need advanced or qualified electronic signatures, signing with digital signature certificates, or controls for 21 CFR Part 11.
- You collect payments or stamp duty with documents, or deliver envelopes by text message or WhatsApp.
- You want desktop and mobile apps: Zoho lists both, even on the free plan, while SignThis runs in the browser.
- You send large volumes through an API and would rather pay per envelope than per plan.
SignThis suits someone who wants signing that stands on its own: no suite to adopt, a PDF in, a sealed PDF out, and a verify page anyone can use. The free plan sends 3 documents a month, and Basic costs $8 a month.
