DuoAI
New
Duo AI is DuoApp’s own assistant, built into the screens your team already uses. It reads certificates and receipts, writes your Monday summary and prices from your own past jobs – then leaves you to check and save. And now you can simply ask it about your business.
Which projects are overspent? What’s waiting for approval? How has the price of 1st fix wiring moved in two years? Type the question and Duo AI answers in a line or two, with the figures behind it – straight from DuoApp’s own reports.
Answers link straight to the right page in DuoApp – a project, an invoice, a plot – so you can act on what you find. Ask a follow-up like “And last month?”, or pick one of the questions it suggests next.
Available now to company admins, as part of Duo AI.

Upload a CSCS, Gas Safe or ECS card or an insurance certificate. Type, number, name and expiry fill themselves in – and it flags a name that doesn’t match or a card that’s expired.
Snap a receipt on site. Duo AI picks the expense type and fills in the supplier, date, amount and VAT, then attaches the receipt when you save.
Every Monday at 7am directors get what moved last week – money claimed, overspend added, approvals waiting, documents expiring – with a plain-English summary on top.
Compare every rate in an estimate with what you’ve actually priced on similar plots, and draft inclusions, exclusions and assumptions in seconds.
Break work into phases and tasks. Assign people. Hide tasks from those who shouldn't see them. Report site issues straight from the task. Every job has a clear owner and a clear status.
Generated directly from project data, with approval workflows and split billing baked in.
Step-by-step workflows for variations, applications and invoice sign-offs. Real-time visibility - no more "who approved this?" emails on a Friday afternoon.
Auto-notify everyone when drawings update. No more chasing the latest revision over WhatsApp.
Project-level controls. The QS sees costs. The site team sees tasks. Subbies see what they need.
Captured from real task activity. Approve and export to payroll in a single click.
Save your house types once, drop up to 500 plots into a project in one go, and build a live what-if price for a whole development - with charts, revisions, optional materials and a professional estimate PDF or Excel export. Win the job, create the project in one click, then see how it's tracking against the estimate.
Stylised illustration. Figures are examples.
Full visibility into all your projects and their values. Assign tasks, hide them from unassigned users, report issues directly within the task to instantly notify management.
Approve and decline variations to keep costs in check. Approval workflows on every project. Add automatic deductions and split invoices between users.
Manage all documentation in one place with automatic notifications when files are updated, so everyone works from the latest version - every time.
Admin users get five numbers on every job - and on every block and level within it - calculated live from tasks, timesheets and sub-contractor claims, and updating on screen the moment work is completed or approved. No month-end wait, no spreadsheet, no asking the accounts team.
Most systems tell you what you've spent. Very few tell you what your subbies have claimed and you haven't yet approved - that's a liability you can see coming.
See the full pictureWe've been working with DuoApp since July 2023, moving subcontractor payments from Excel to an online platform. They've been consistent, reliable, and supportive - always delivering on their promises. The result is software that feels tailor-made for us and a partnership many would envy. We're now expanding DuoApp into other areas of our business - and we haven't looked back.
It has been instrumental in improving our business and our processes efficiencies. From streamlining our sub-contractor payment process, to offering our labour force a platform for document sharing, they've helped us and met our needs.
Since using DuoApp, our sub-contractor payment processes have become a breeze. It's efficient, easy to use and looking forward to seeing how it evolves to further help our business requirements.
No contracts. No setup fees. Up and running in days, not months. See DuoApp on a real project before you commit.
