One-time $29 on first proposal. No recurring charges. No per-proposal fees.
Built after losing $4,200 to a client who gave glowing feedback, approved every revision, then vanished the day files arrived. ProposalLock does one thing: your files don't move until money does.
No mobile app. No team plans. No monthly fee. Just the thing you need.
"Sent files. Client said will pay Friday. That was 3 weeks ago."

2+ hours chasing invoices every week instead of doing client work.

Every payment is cryptographically verified before unlocking files.
Hidden until paid
File URLs are never exposed in the browser, API, or source code until payment clears.
Flexible delivery
Link to Google Drive or Dropbox, or upload files directly for 30-day secure hosting.
Does my client need an account?
No. Your client clicks the link you send, sees the project summary and price, and pays with a credit card. No signup, no account, no friction. Files unlock automatically the moment payment clears.
Does this work with Google Drive or Dropbox?
Yes. Paste any shareable link -- Google Drive, Dropbox, OneDrive, or a direct URL. Use "anyone with link" sharing so the file is accessible once unlocked.
What happens if my client doesn't pay?
The file URL stays hidden. They see a locked state with the payment button. No file access until payment clears.
Can I change the price after sending?
No. The price is locked when the proposal is created. This protects both you and your client. Create a new proposal if you need a different price.
How much does ProposalLock cost?
$29 one-time for lifetime access. No subscription, no per-proposal fee, no recurring charges. When your client pays, LemonSqueezy takes a small transaction fee and you keep the rest. ProposalLock itself never takes a cut of your proposal revenue.
How do I track my proposals?
Log in with your email to access your dashboard. You will see all your proposals, payment status, and total revenue at a glance.
Can I upload files directly instead of linking?
Yes. Toggle to "Upload file" when creating a proposal. Files up to 50MB are stored securely in Supabase Storage. After payment, your client gets a signed download link valid for 30 days.
Is my data secure?
Yes. We use HMAC-SHA256 webhook verification, encrypted database connections, and Supabase Storage with signed URLs that expire after 30 days. Payments are processed securely through LemonSqueezy.
