What it does on a building job

  • Labour by the day, with materials, skips and hire on lines of their own.
  • The customer says yes on a link, and pays a deposit if you ask.
  • If the job grows, save a new version for the customer to agree.

On a home, the payment terms are the ones you agreed

The Construction Act sets rules on stage payments, and on suspending work when a sum due is not paid. Section 106 says those rules do not apply to a contract with a residential occupier.

A residential occupier is a customer who lives in the home, or means to. On that job, the Act adds no stage payments and no right to suspend.

What you say about the work matters too. Under the Consumer Rights Act, what you say or write can become part of the contract, unless a change is expressly agreed.

Read the sections behind this

Section 106 covers a contract that principally relates to work on a dwelling one of the parties lives in, or intends to live in. A dwelling means a house or a flat.

For contracts the Act does cover, section 109 gives a right to stage payments, unless the work is to last under 45 days.

Section 112 lets an unpaid party suspend work after giving at least seven days' notice. Section 111 sets out a notice to pay less than the sum due.

Under section 51 of the Consumer Rights Act, where no price was fixed, the customer must pay a reasonable price, and no more.

This page states what the documents say. It is not legal advice, and whether a rule reaches a particular job turns on facts a web page cannot see. Sources last read 13 September 2026.

What it does not do on a build

  • It takes one deposit on a quote, not a schedule of stage payments.
  • It does not take CIS off the people you pay, or file a contractor's monthly return.
  • It does not measure from plans or count up materials for you.

What it costs

Pro is £29 a month or £290 a year, with no per-seat fees and no contract. Every new account starts on a 14 day free trial of Pro with no card needed, and drops to the free tier rather than switching off.

Frequently asked questions

Can a customer approve an extra before I start it?

Yes. Save the quote as a new revision with the extra priced in. The customer approves the new version on a link, and the old link stops working.

Can I put another trade's work on my quote?

Yes. A subcontractor line carries what you pay them and the markup you add. What you pay out is saved as a draft expense.

Can I quote a range when I cannot see behind a wall?

Yes. A quote priced as a range stays a range on the PDF, on the link and in the email. It is never turned into one number.

Does it work out CIS when I work for a main contractor?

CIS deductions on your own invoices are switched on account by account, and are not part of a new account today. The free CIS checker on this site works out what should have come off.

What does the free tier include?

The free tier runs 3 quotes and 3 invoices a month, end to end: build the quote, send the PDF, let the customer approve it in the portal, and invoice it. The AI pricing and description tools, expense tracking, certificate filing and reports are Pro. The HMRC year-end tools are Pro + Tax. The cap is small on purpose. A free tier big enough to run a trade on has to be paid for by the traders who do pay, and they are one-person businesses on a flat £29 a month with no per-seat fee. What the free tier proves is the whole loop rather than the volume: build the quote, send it, let the customer approve it, invoice it.
