The problem
Without proof of delivery, you're exposed to disputes, late payments, and scope creep.
Clients deny receiving work. Without proof, you lose the argument and potentially the payment.
A client raises an issue 3 months later. You have no timestamp, no record, no evidence.
Screenshots in Slack, emails in Gmail, files in Drive. Nothing consolidated, nothing timestamped.
The solution
Create a proof. Send to client. Get acknowledgement. Done.
Screenshots, files, descriptions. Bundle everything into one proof package for your client.
Your client reviews and clicks "Acknowledge". No account needed. One click in their browser.
IP address, timestamp, client email, SHA-256 hash — a tamper-proof certificate you can show in court.

FAQ
Acknowledgement certificates include IP address, timestamp, email, and SHA-256 hash. While not a replacement for formal contracts, they provide strong supplementary evidence in disputes.
