Final delivery for freelance creatives
Never hand over finished work on a promise again.
Send a payment-gated handoff. They preview, pay, and unlock the files.
No client account. No Prooflock commission.

Close the job cleanly
Emailing final files and hoping they pay leaves the handoff loose. Prooflock makes payment the condition for delivery.
A real invoice
Every envelope carries a Stripe invoice: an invoice number, a PDF, and a due date. Something your client's bookkeeper can put through the books.
Chasing runs itself
Reminders go out halfway through longer terms, 3 days before the due date, and on the due date. Chasing stops being a task you own.
No client account
Your client clicks a link and pays. No account to create, no app to install.
How it works
Three steps. The handoff closes when the invoice is paid.
- Step 1
Create the handoff
Add the finished files, client email, price, and payment deadline.
- Step 2
They preview and pay
Your client opens a link, reviews the watermarked previews, and pays.
- Step 3
Files unlock after payment
The originals unlock for download as soon as payment clears.

Common questions
What file types can I send?
Images and PDFs, up to 50MB per file. Vector source files, archives, and fonts are not supported yet: if your final delivery is a .zip or an .ai, Prooflock cannot carry it today. Wider format support is planned but not shipped.
What if the client never pays?
Reminders keep going out while the link is live. If the payment term ends unpaid (7, 15, or 30 days, set by you), the link expires, the invoice is voided, and the files are deleted from Prooflock. Your client never had the originals.
Does my client need an account?
No. They get one link. Opening it shows the previews and the invoice; paying unlocks the download. No signup, no password, no app.
How does the money reach me?
Through Stripe, directly into your own Stripe account. Prooflock takes no commission on the payment. Connecting Stripe the first time takes 5 to 10 minutes, because Stripe asks for your bank details and identity so clients can pay you directly. You do it once; every envelope after that uses the same account.
