Stop chasing printed, signed, scanned copies. PracticeStacks lets clients accept and sign engagement letters and proposals digitally with OTP verification — every signature captured with a tamper-proof audit trail your firm can rely on.
Purpose-built for CA, CS & Tax firms in India.
Clients confirm their identity with a one-time password before signing, so you know the right person accepted — not just anyone with the link.
Every signature records the timestamp, IP address, and viewing history. If terms are ever questioned, you have a complete, defensible record.
Clients accept and sign from a phone or laptop in their browser — no app, no printer, no scanner. Most engagements close the same day.
E-signatures are part of the proposal flow. Send a branded proposal, the client reviews and signs, and onboarding triggers automatically.
Unsigned engagement letters get gentle WhatsApp and email nudges until the client signs — no manual chasing from your team.
Once signed, both firm and client get a stored, accessible copy. No more hunting through inboxes for the final executed document.
Share the proposal or engagement letter via WhatsApp or email. The client opens it in their browser — nothing to download.
The client confirms identity via OTP and signs digitally. The timestamp, IP, and view history are captured automatically.
The signed copy is stored for both sides and onboarding kicks off — document and credential collection starts immediately.

The client confirms a one-time password (OTP) sent to them before signing, so you have evidence the intended client accepted — not an anonymous link visitor.
Each signature records who signed, the date and time, the IP address, and the document viewing history. If terms are ever disputed, you have a complete record.
No. Clients sign in their browser on any device. There's no app, no printing, and no scanning — most engagement letters get signed the same day.
