Your margin lives in the detail — a variation never logged, a bill filed in the wrong month, a decision agreed on site and never written down. ClientBuild puts every project, every pound and every conversation in one place.
Every trade section tracked against budget — billed, awaiting and remaining — with progress bars that move as bills land. Spot an overrun weeks before it becomes a problem.
Photograph or upload any supplier invoice — supplier, date, net, VAT, CIS and gross read automatically. Assign the trade section in one tap and it flows straight into your live budget.
Monthly valuations across the life of a project, retention held automatically at your set percentage, VAT applied, and a professional invoice generated in one click.
Every variation gets its own code and value — including FOC items — so nothing is forgotten at final account. PC sums tracked separately with running balances.
A Gantt-style programme your client can actually read, plus snag lists with photos and completion tracking — from any phone, on any site.
Assign decisions to your client with due dates and priorities, and keep project conversation in a threaded discussion — out of WhatsApp and on the record.
Scope of works, drawings organised by floor and revision, and client choices — kitchens, tiles, fittings — with an approval trail. No more "I never agreed to that".
Every bill, photo, drawing and document stored against its project — organised by section and revision, searchable, available from any device. No hunting through email for last month's invoice.
Set a percentage claimed against each work item and the invoice writes itself — on your letterhead, itemised line by line, with retention and VAT calculated. Save as PDF and send.
Add a Client Login button to your own website and clients land in a portal carrying your logo and company name only. They see progress, valuations and documents — you control exactly what's visible.
Bills and invoices auto-sync straight into Xero — enter it once, never again. No double adding, no month-end catch-up, no re-keying. Included in the same price at no extra cost.
Encrypted in transit and at rest, with automated daily backups and versioned snapshots. Back up, import and restore from inside the app — and export your data whenever you want.
Suppliers still send paper. Merchant tickets live on receipts. Emails arrive as PDFs. Snap it or upload it and the figures are read for you — then you assign the trade section and your budget updates instantly.
From the first budget to the final payment, ClientBuild keeps your numbers connected so your margin stays protected — and you can prove every figure.

Tick off what's been done this month and ClientBuild writes the invoice for you — on your letterhead, itemised by work completed, with retention and VAT calculated and a breakdown your client can actually follow.
This is the screen your client actually sees — your logo, your company name, your project. No mention of us anywhere. Pick a company below and watch the portal re-brand.

Drop one link into your site's menu and your clients log straight into their project. They land on your branding and nothing else — our name never appears in front of your customer.
Spreadsheets don't chase decisions. Enterprise software needs training and a per-user licence. ClientBuild sits where the trade actually lives.

* Free — until an overrun you never spotted costs you five figures. Enterprise pricing shown is typical market range, not a quote from any named product.
Move the sliders to your own numbers. This is an illustration based on your inputs, not a promise of savings — but most of the time it makes the £59 look small.
No per-user fees. No per-project fees. No feature tiers. No card needed for the trial. Join during the launch window and your price is fixed for as long as you stay subscribed.
Subscribe during the launch window and you pay £59/month. That price is fixed for as long as your subscription stays active — it does not rise on you later. Once the window closes, new customers pay £89/month. If you cancel and come back afterwards, you'd rejoin at whatever the standard price is then.
No — it's built for the whole industry. Main contractors, design & build firms, developers, electricians, plumbing & heating engineers, joiners and landscapers — any trade running projects with budgets, bills and clients. Trade sections are fully customisable to how your business works.
Every client you invite sees a portal carrying your company logo and branding — not ours. You control exactly what they see: progress, valuations, drawings and choices — never your internal margins or supplier costs.
No. Sign up and you get 14 full days of everything, no card required. If you decide to continue, add your card and you'll be billed from day 15 at your founding-member rate.
Upload a photo or PDF of any invoice and the figures are read for you — supplier, invoice number, date, net, VAT and gross, with CIS tracked where it applies and reverse-charge VAT totalled separately for HMRC. You assign the trade section it belongs to and your budget updates instantly. The original document stays stored against the project.
It comes out as a proper letter on your own letterhead — your logo, your client's address, a reference line, and every work item listed with the percentage claimed this month. Sub total, retention and VAT are calculated for you, with the grand total due clearly set out. Save it as a PDF and send it straight to your client.
Xero integration is in development and will be included in your price at no extra cost. Bills and invoices sync so you enter something once — no double adding, no re-keying at month end. Email support@clientbuild.co.uk to be notified when it goes live.
Yes. It runs in the browser on any phone, tablet or laptop — photograph a bill, check a budget, tick off a snag or answer a client from wherever you are. Nothing to install.
Data is encrypted in transit and at rest, with automated daily backups and versioned snapshots. Backup, import and restore are built into the app, and you can export your data at any time — you own it.
Yes. Cancel with one click from the billing portal and you won't be charged again.
Email support@clientbuild.co.uk — a real person in the UK will get back to you, and we can walk you through your first project.
No card, no commitment. Set up your first project in minutes, invite a client, and see what a properly professional workflow looks like.
