“…extra €400 on one job.” — John, carpenter
Job extras
The extra was easy to agree. It's the bill that's hard.
"Yeah, go ahead" on a Tuesday. Then the invoice lands and suddenly it's "I don't remember agreeing to that." Now you've got two bad options: eat the cost, or fight for money you already earned.
Variation Vault keeps the extra, the price, the photos and the customer's approval together on the job — so when the invoice goes out, there's nothing left to argue about.
One written-off extra costs more than a year of Variation Vault.
However it comes up
Two ways an extra comes up. One way to handle it.
You spot it
“While I'm here, that cable's perished.”
You see work the customer never would. Send the price before you start — and get paid for what you'd normally swallow.
They ask for it
“While you're here, can you sort the hallway too?”
Don't kill the goodwill saying no, and don't do it for nothing. Send the price, they tap approve — you stay the good guy and get paid.
Either way — take a photo, set the price, send the link, get the yes on record.
The short version
Variation Vault is an app on your phone that gets every extra approved in writing — before you bill it.
Two minutes on site. That's the whole job.
The customer doesn't download anything. They just tap a link.
It's not invoicing software. It's the step before the invoice — so the invoice never gets disputed.
How it works
From “just add it” to approved — in three steps.
1
Set up the job
Customer, address, what was quoted. Two minutes, once per job.
2
Capture the extra
On site, on your phone: take the photos, type the price, add the VAT. Done before the kettle's boiled.
3
Send the link
Text it, WhatsApp it, email it. The customer taps Approve — and the yes is saved with the date and time, attached to the job forever.

What the customer sees
The link does the awkward part for you.
You never have to chase, justify, or argue the price face to face. You send a link. The customer sees the work, the photos, the cost and the VAT — and taps Approve. To them it feels like a normal confirmation, not a confrontation.
One link, sent by text, WhatsApp or email
They see the photos, the price, the VAT, the timing
One tap to approve or reject — no app, no account, no password
The decision saves itself to the job

Proof & billing
Every approved extra becomes proof you can bill on.
Each approval is saved with the timestamp, the photos, the notes and the price — so the extra is ready to add to your invoice, and easy to back up if anyone ever questions it.
Timestamped yes
The exact date and time the customer approved, on record.
Photos attached
Site photos stay pinned to the extra, not lost in a camera roll of 4,000 pictures.
Proof PDF
One tap pulls a clean proof pack for your records, your accountant, or a stubborn customer.
Ready to bill
Approved extras carry the price and VAT, ready to drop into your invoice.

A note from the founder
I'll be straight: I've never been on the tools. I build software — and when I went looking for a problem worth solving, trades kept handing me the same one: the work gets done, then the bill gets argued. So I built the fix, and nothing else. If something's not working, you email me and I fix it.

Built for trades who spot extra work — and trades who get asked for it
Whether you see work the customer missed or they hit you with “while you’re here, can you just…”, if extras come up mid-job, this is for you.

Trade reviews
What trades are saying
Real extras, spotted on site and approved before the invoice went out.
Extra €400 on one job
“I was in doing a fit-out when the owner asked for new wardrobes and presses on top. Raised the extra in Variation Vault, sent it over, got the yes. Easy.”
€240 extra, first residential job
“Booked in for window cleaning, but on site I spotted the gutters were in bad shape. Raised the extra using Variation Vault — customer approved it in 5 minutes.”
Upsold hedge trimming on site
“Was already on site doing the usual. Spotted the bushes needed doing, sent the approval, got it signed off there and then.”
