Question 1

Is SignDoxs legally binding?

Accepted Answer

Yes. SignDoxs signatures comply with the US ESIGN Act, UETA, EU eIDAS regulation, and equivalent eSignature laws in 190+ countries. Every signed document includes a cryptographic SHA-256 fingerprint and a complete audit trail with timestamps and signer hash chain — admissible in court.

Question 2

How is SignDoxs different from DocuSign?

Accepted Answer

SignDoxs offers unlimited documents on the $15 Business plan with REST API included. DocuSign charges $40+/user for Business and gates the API behind a $720/month add-on. SignDoxs also includes unique features: public QR verification page on every signed PDF, eStamp designer, AI field auto-detection, and mobile-first signing without requiring an app.

Question 3

Can I use SignDoxs without a subscription?

Accepted Answer

Yes. The pay-as-you-go option lets you sign or send one document or envelope for $1.50 without a monthly subscription. Monthly paid plans include a 7-day free trial.

Question 4

Which file types can I sign with SignDoxs?

Accepted Answer

Upload PDF, DOCX, TXT, PNG or JPG files. Non-PDF formats are automatically converted to PDF on upload so signers always receive a clean signing-ready document.

Question 5

How do recipients verify a signed document is authentic?

Accepted Answer

Every signed PDF includes a QR code on every page. Anyone — even without a SignDoxs account — can scan it to land on a public verification page showing the document status, completion date, SHA-256 fingerprint, and tamper-evidence proof.

Question 6

Does SignDoxs work on mobile?

Accepted Answer

Yes — SignDoxs is mobile-first by design. The signing portal uses a native bottom-sheet pattern with touch-optimized canvas signing, sticky CTAs in the thumb zone, and 44px+ touch targets following Apple Human Interface Guidelines. No app download required.

Question 7

Can I add a company stamp or seal to a document?

Accepted Answer

Yes. SignDoxs includes a stamp designer for company seals, official seals, approval stamps (APPROVED, PAID, RECEIVED), date stamps, and certified-true-copy marks. Place a stamp on any document like a signature field. On Business plans, the verified stamp library adds auto-incrementing serial numbers, locked metadata, workspace sharing, revocation, and a public QR verification link for every stamp applied.

Question 8

How do I verify a stamp is genuine?

Accepted Answer

Each stamp SignDoxs applies mints a unique verification token at /verify-stamp/:token. Scan the stamp's QR code or open the link from the document's audit certificate to see the stamp's name, serial number, the document it was applied to, and whether it has been revoked — so anyone can confirm a company seal or approval stamp is authentic and current.
