The problem

No contract, every job is a gamble

If you start work on a WhatsApp deal alone, you pay the price: clients who don't pay, scope that keeps growing, deadlines no one respects.

Clients who don't pay and you have nothing to claim with

They ask for extras and tell you "we assumed it was included"

Generic Word templates that protect nothing

Lawyers are expensive and take days to send a contract

The solution

You make the quote. Exhaling drafts the contract.

Templates written by lawyers for tradespeople, freelancers and businesses. They auto-fill from the quote. The client signs from their phone.

Real legal templates

Construction contract, services agreement, maintenance, binding quote, NDA. Drafted by lawyers.

Auto-filled

Pulls data from the quote: client, line items, totals, deadlines, payment terms. You don't type a thing.

Signed from the phone

Client gets the contract on WhatsApp and signs with their finger. In 30 seconds. No printing, no scanning.

Holds up in court

Timestamp, document hash and IP record. If there's a dispute, you have evidence that holds up legally.

Dead simple

From accepted quote to signed contract.

01

Pick the template

Construction, services, maintenance, whatever you need. Loaded in one tap.

02

Send it on WhatsApp

Client receives the contract ready to sign. They read it, tick the boxes and sign with a finger.

03

Ready to start

Comes back signed to your phone. Timestamped and legally valid. You start the job with peace of mind.

Everything included

Everything you need to protect yourself

Electronic signature

Client signs from their phone with a finger. Compliant with the EU eIDAS regulation on e-signatures.

Trusted timestamp

Every contract carries a certified date and time. No one can claim it was signed on a different day.

Tamper-proof document

Once signed, the contract is sealed with a hash. If anyone changes a comma, it shows.

Court-ready evidence

We log IP, time, device and geolocation of the signer. If it goes to court, you have evidence.

Ready-made templates

Construction, services, maintenance, NDA, binding quote. Drafted by specialised lawyers.

Payment clauses

Set deposit, milestone payments and terms. If the client doesn't pay, you stop the job with legal backing.

Locked-in scope

Quote line items flow into the contract. What's not written, isn't included. Extras get billed separately.

Penalties & guarantees

Late-payment, warranty and termination clauses. If the client wants to back out, they pay.

Send via WhatsApp

Client gets the link on WhatsApp, opens it and signs. Nothing to install.

Templates

A template for every type of job

Drafted by lawyers specialising in construction and renovation. Ready to use.

Construction contract

For renovations and new builds. Defines scope, price, deadlines, milestone payments and warranties.

Services agreement

For one-off jobs and small works. Quicker, less paperwork.

Monthly maintenance

For recurring clients. Fee, scope, auto-renewal and termination notice.

Binding quote

If the client signs it, they can't haggle later. Protects you from price-shopping.

NDA / confidentiality

For clients sharing sensitive info. You sign, they trust.

Addendums & changes

When the job changes, you generate an addendum. Client signs. Everything documented.

I used to start jobs with nothing but a WhatsApp chat. One client backed out halfway and I lost £8,000. Since I started using Exhaling contracts, I don't start anything without a signature. I've collected every outstanding bill.

FAQ

Common questions about contracts

You have both options, depending on the size of the job. For small repairs, when you share a quote you can flip on "Ask for client acceptance": the client sees a one-tap "Accept" button (no legal signature, just a timestamp record). For serious jobs, generate a full contract with eIDAS signature here — with milestone payments, warranties and court-ready evidence.

Yes. Electronic signatures are covered by the EU eIDAS regulation. They hold up in any EU court. It's the same as a wet signature, but with more proof.

We log their IP, device, exact time and location when they signed. If they deny it, you have the technical evidence to prove it.

Of course. They're drafted by firms specialising in construction. If your lawyer wants to tweak a clause, they can.

It helps you not have any. With a signed contract, milestone payments and a non-payment clause, you stop the job at the right moment and have what you need to claim.

You generate an addendum in 30 seconds: new line items, new price, new signature. Work done, work paid. No arguments.

Yes. Templates adapt whether you're a sole trader, ltd or co-op. Pick the type and the tax and liability clauses adjust.
