Know the moment your
invoice is opened.
LinkProof turns any invoice link into a tracked link — so you see the exact time, location, device, and network behind every open. With a push alert the second it happens.
No credit card. Set up your first link in under a minute.
Without tracking, you're guessing
Sending an invoice into a black box is the norm. It doesn't have to be.
The old way
- Send an invoice and hear nothing back
- No idea if it was opened, ignored, or lost
- "I never received it" — and no way to disprove it
- Chase payment blind, with zero signal
- Generic open-tracking that bots trip constantly
With LinkProof
- Know the exact moment it’s opened
- See the city, device, and network behind each open
- Proof of delivery you can actually point to
- Follow up with timing and context on your side
- Bot and VPN detection so the signal is real
Create. Send. Know.
Create a tracking link
Paste your invoice or destination URL. Optionally set the expected city and network for the recipient.
Drop it in your email
Use the generated button or a plain link. Send your invoice exactly like you always do.
Get alerted on open
The moment it’s clicked, you get a push notification and a full breakdown of who, where, and how.
Everything you need to track an open
Location, device, network, and intent — captured the instant someone clicks, and surfaced the moment you need it.
Real-time push alerts
Get an OS notification the instant your invoice is opened — location, device, and network included.
Live location map
A 3D globe plots every open by city and country, so you can see exactly where your invoice landed.
Device & browser
Know whether it was opened on an iPhone in Safari or a Windows desktop in Chrome — down to the version.
Bot & prefetch filter
Email scanners and link prefetchers are detected and flagged, so a "real human opened it" means exactly that.
ISP, VPN & proxy
See the network behind each open and get warned when a click comes through a VPN or datacenter IP.
Email button generator
Generate a styled, copy-paste HTML button for your invoice emails in seconds — no code required.
