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.

01

Create a tracking link

Paste your invoice or destination URL. Optionally set the expected city and network for the recipient.

02

Drop it in your email

Use the generated button or a plain link. Send your invoice exactly like you always do.

03

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.
