Everything you need to run profitable projects.

The client's own view — valuations, retention and VAT laid out in full. Figures from a sample project.
Your clients never see your profit. Client mode has no route to it — no tab, no total, no export.

What your client sees

  • Contract value, budget by trade section and remaining
  • Monthly valuations with retention and VAT set out in full
  • Total due, balance paid and balance outstanding
  • Programme dates, drawings, choices and approvals
  • Their own actions, deadlines and project discussion

What stays private to you

  • Every supplier bill and what you actually paid for the work
  • Anticipated profit, actual profit and loss absorbed
  • Trade-by-trade spend against budget and your mark-up
  • CIS deductions, reverse-charge VAT and amounts held for HMRC
  • Subcontractor rates, payment status and internal notes
The Bills tab simply is not there in client mode. Your margin is not hidden behind a permission you could switch on by accident — the client view has no access to it at all.

FAQ

Straightforward answers

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.

Take a fortnight. See if it fits.

No card, no commitment. Set up your first project in minutes, invite a client, and see what a properly professional workflow looks like.
