Comparison
Adobe Acrobat Sign is a great fit if you already live in Adobe Acrobat or Microsoft 365. If you don't — and most landlords + contractors don't — you're paying for an ecosystem you'll never touch.

FAQ
Under the U.S. ESIGN Act (2000) and UETA, yes — both vendors capture intent, identity, timestamp, and IP, which is what those laws require. Adobe Sign additionally supports EU eIDAS Qualified Electronic Signatures, which carry stronger legal weight in EU jurisdictions; we don't. If you're operating in the U.S., the practical legal difference is small.
If you're using Acrobat Pro daily for PDF editing, probably don't switch — you're getting two tools for the bundle price. Switch if you're paying for Acrobat *just* to e-sign, or if you want a separate signing flow that you can cancel without affecting your PDF editing setup.
Yes — we accept any PDF up to 32 MB. Edit in whatever tool you like, upload here when it's ready to sign.
We don't integrate with M365. You'd attach the sealed PDF to an email by hand, same as you would with any other contract. If that step is a dealbreaker, Adobe Sign is the better tool.
At some volume — typically when you need eIDAS, KBA, or deep Microsoft 365 hooks — Adobe Sign or DocuSign becomes the right call. Your existing sealed PDFs stay valid (they verify by hash, not by vendor). We'd rather see you graduate than retain you with features that don't fit.
Sample plan covers 2 documents lifetime — enough to see how the full flow works. No card required.
