Create Your First Proposal Free

Works in 30 seconds. · See what your client sees

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.

Sound familiar?

"Sent files. Client said will pay Friday. That was 3 weeks ago."

-- r/freelance, 2024 (100+ upvotes)

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

HoneyBook charges $66/month. You just need a pay-to-unlock link.

Files unlock on payment

Instant, automatic access

Create a proposal

Always free. Create a proposal, set your price, and get paid before your client downloads.

Quick-start templates

Client sees this on the proposal page as a preview of deliverables before paying.

Security you can trust

HMAC-verified webhooks

Every payment is cryptographically verified before unlocking files.

Hidden until paid

Flexible delivery

Link to Google Drive or Dropbox, or upload files directly for 30-day secure hosting.

Frequently asked questions

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.

Is ProposalLock really free?

Yes. Creating proposals is completely free for freelancers. When your client pays, LemonSqueezy processes the payment and takes a small transaction fee. You keep the rest -- no platform fee from ProposalLock.

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.
