Built

Everything here works in BuilderOS today.

July 2026

Price a job, send a proposal, the client says yes online

Price the job stage by stage with your own charge-out rates. Turn it into a proposal and send the client a link. They read it on their phone and accept, and the price locks in.

July 2026

Timesheets from a photo, and a clean file for payroll

Snap a paper timesheet or forward it in. The hours land against the right person and job. Approve the week and hand payroll a clean file.

July 2026

Costs against what you quoted

Every supplier and subbie invoice sits against the line it was priced on, so you see a stage running over while there's still time to do something about it.

July 2026

Progress claims and variations

A proper payment claim and tax invoice, sent as a PDF and a link. Variations priced and signed off before the work gets done.

July 2026

Site diary and the job timeline

A running diary for every job. A timeline showing the programme you agreed next to where the job is actually tracking, with delays recorded as they happen.

August 2026

It reads supplier quotes and invoices

Drop in a PDF and it reads every line and total. It works out which stage each line belongs to, in builder's words, and learns from every correction you make.

September 2026

Quotes go straight into your price

The lines from a subbie or supplier quote drop into your pricing schedule. When the invoice arrives it's checked against what was quoted. Before a proposal goes out, it warns you if a quote hasn't been accounted for.

September 2026

One Inbox for everything that arrives

Uploads and emails are read and sorted for you. A PDF with seven invoices in it becomes seven invoices. Each job gets a code the merchant counter can quote back to you.

September 2026

Subbie licences and insurance, with reminders

Insurance certificates and LBP licences are filed against the subbie, with the expiry date. When cover is about to run out, you're reminded, and one click asks them for the new certificate.

September 2026

Ask it anything

Type a question about any job, like what did we price the framing at, or who hasn't sent a timesheet, and get a straight answer from your own numbers. Your chats are saved.

September 2026

Your company's own email address

Forward or CC emails to it and they're filed on the right job, attachments and all. Every job keeps a history of what happened, and the reading and reminders carry on when nobody has the app open.

September 2026

Your whole team, each seeing their own bit

Invite your office manager, foremen and crew. Each person sees what their job needs. Your foreman sees his crew's hours, and your margins stay yours.

September 2026

Variations your client approves on their phone

Attach photos and the subbie's quote, send it, and the client approves or declines on their phone. If they decline, you get their reason straight away.

September 2026

Proposals that look the part

Three designs to choose from, with your logo, your team, past projects and what clients say about you. Your own words throughout, and the price broken down the way you want the client to see it.

September 2026

Charge-up jobs

Set a rate card for the job and claims are built from the hours your crew approved and the costs that came in, so you're never charging ahead of the work.

September 2026

PC sums and provisional sums, done properly

When the real invoices come in, firm up the allowance. The difference goes on the next claim with a plain explanation your client can follow.

September 2026

Fix a timesheet before you approve it

The office can correct a crew member's day, and the crew member sees what changed and why. Once a day has been billed to a client, it locks.

Being built now

What's on the bench this month.

Setting up our first builders

Moving BuilderOS onto its live system and setting up our first builders on their real jobs, with their own rates and their own crews.

Just say it

Hold the button, say your question on site, and it answers. No typing in the ute.

BuilderOS on your home screen

Add it to your phone's home screen and it opens like an app. Nothing to download from an app store.

Next

Coming next, in roughly this order.

Reports

Which jobs made money and which didn't. What you quoted against what it cost, and what's coming up in the next few months.

Updates for your client

Progress updates with photos your client can open on their phone, so the Saturday phone call doesn't need to happen.

Photos and voice notes in the site diary

Snap it, say it, and it lands on the right job and the right day.

Won and lost

Mark a job lost with the reason, and see which work you win and why.

After that

Planned, and early builders help decide the order.

Xero

Claims and invoices sent straight to Xero, with no double entry.

Health and safety

Site safety plans, toolbox talks and critical risks, built around the law changes coming into force in April 2027.

Search

Find any job, person or document by typing a few letters.

The build note

Stay up to date with progress.

A short note when something ships: what got built and what it fixes on a real job. No drip campaign.
