Frequently Asked Questions
How do I migrate from SignNow to TurboDocx?
You rebuild your signing workflows in TurboDocx by recreating your templates and signer fields, then wire signing into your app using the REST and E-Signature APIs and the SDKs for JavaScript/TypeScript, Python, PHP, Go, or Java. Webhooks with event filtering and retry handling replace any polling you had on SignNow event notifications. There is no one-click importer, so plan to recreate templates rather than transfer them automatically.
Does TurboDocx charge per signature or per invite like SignNow API?
No. TurboDocx uses per-user monthly subscription pricing with a free tier and unlimited signatures on the Pro plan; its standard plans are not metered per envelope, and per-envelope pricing is available only as an option. The SignNow eSignature API is usage-based per invite, starting at $2 per invite for 500 invites and dropping to $1.20 per invite at 5,000 invites.
Is TurboSign legally binding like SignNow?
Yes. TurboSign e-signatures are legally binding under the U.S. ESIGN Act and UETA, with detailed audit trails for compliance and email authentication for signer verification. SignNow similarly provides court-admissible audit trails, so both meet the standard legal requirements for electronic signatures.
Does TurboDocx offer the same developer tools (API, SDKs, webhooks)?
Yes. TurboDocx ships a REST API, an E-Signature API for embedded signing, and webhooks with event filtering and retry and dead-letter handling. Its SDKs cover JavaScript/TypeScript, Python, PHP, Go, and Java. SignNow SDKs cover Node.js, C#, Java, Python, and PHP, so if you specifically need C# stay aware of that difference, while TurboDocx adds Go.
What can TurboDocx do that a signing tool alone cannot?
TurboDocx combines template-based document and presentation generation (DOCX, PPTX, PDF), sales quoting and CPQ through TurboQuote, and legally binding e-signatures in a single product, so you can create the document or quote and sign it in one workflow. It also maintains the MIT-licensed open-source @turbodocx/html-to-docx library for converting HTML to Word with no headless browser dependency.
