Stop losing money to "small changes" requested on WhatsApp.
ChangeProof by LinkVault captures client requests from WhatsApp and email, detects potential billable changes, and lets you convert them into approved work before starting.
The client does not need to create an account.
Your clients continue using WhatsApp and email as usual.
Client (WhatsApp)
Online
Your client requests are scattered everywhere.
Your clients request changes via WhatsApp, email, calls, voice notes, and scattered messages.
"Can you change this quickly?"
At first it seems like a quick five-minute adjustment.
"I thought that was included."
Then it turns into unbudgeted extra work.
"We already talked about it on WhatsApp."
No one remembers what was included, what was approved, or if it was billable.
"Why is this extra?"
Tense conversations at the end of the project due to a lack of clear boundaries.
"ChangeProof helps you convert messy conversations into clear, approved, and billable work."
Your clients keep writing to you as usual.
ChangeProof keeps the proof.
ChangeProof does not force your clients to use another complicated portal or to sign up. They can keep sending you messages via WhatsApp or email just like they always have.
The system detects and registers. The freelancer decides.
You decide which messages convert into official change requests.
You define the scope, price, and deadline for the additional change.
Your clients approve with a single click from a secure link.
Total Control in Your Hands
ChangeProof's AI analyzes the commercial intent of the message and presents you with suggestions. You can convert it into an official change quote, archive it, or simply add it as an internal client feedback note.
From client message to approved change in minutes.
The ultimate workflow to protect your time and ensure every hour of extra work is properly compensated.
Capture the request
Clients send messages via WhatsApp or email as usual. ChangeProof captures or registers the message inside your LinkVault workspace.
Detect the intent
ChangeProof analyzes the message and suggests what it could be: billable change request, bug, urgent question, or delivery.
You review it
Nothing is automatically sent to the client. You have the commercial control to ignore, save as a note, or create an approval link.
Send approval
Create a clear proposal with what is included, what is not, the price, and the deadline. You send a simple and clean link for the client to sign.
Get proof
The client approves the change without creating an account. You get a record with date, time, approved scope, price, and client identity.
Convert WhatsApp messages into controlled work.
Most clients won't open a complex project management tool just to request a small tweak. That's why ChangeProof adapts to the way they already communicate with you.
Your client can continue using WhatsApp as usual. You get a structured inbox where messages are classified and converted into billable changes in seconds.

Important note: ChangeProof does not make commercial decisions for you automatically. It only suggests. You maintain full commercial control.
Detect potential billable changes before they get lost.
The Smart Inbox helps you detect client messages that could turn into extra work. It organizes the flood of incoming messages and visually shows you what needs attention and what actions you can take.
You decide what becomes a change.
Not all client messages should turn into an additional invoice. Sometimes it's a bug to resolve, sometimes it's included in the original scope, and sometimes it's just a clarifying question.
ChangeProof helps you identify the underlying conversation intent using AI, but the final decision is always yours.
AI helps you organize the conversation. You manage the relationship with the client.

Want automatic capture from WhatsApp?
We are building a robust integration with WhatsApp Business so that incoming client messages are automatically registered and classified within your ChangeProof panel.

Your clients will continue using WhatsApp normally. You will have more control over what becomes official work.
Communication with your clients remains under your control.
ChangeProof is designed to help you organize client requests, not to take control of your conversations or automate replies without your explicit consent.

Nothing is sent to the client until you review, edit, and decide to explicitly send it.
AI is only an assistant
Suggestions for intent, scope, and price are pure commercial recommendations. You decide.
No signup for clients
Your clients do not need to register or create accounts to approve the proposed scopes.
