From site evidence to invoice in one connected system — photos, quotes, invoices, timesheets, receipts and email on one dataset. Keeps Building Control happy. Free for every site worker.
Arqor OS is opening to a first group of trades — no card, no commitment.

Print a QR code on the site board. Any trade scans it, types a name, and is capturing evidence in seconds — timestamped, GPS-tagged, pinned to the exact spot on the plan. It works with no signal and syncs later.
1 · Scan
The QR on the site board. No account, no app store, no login.
2 · Snap
Photos stamped with time and place, marked up on site, offline-first.
3 · Proven
Pinned to the plan, ready for Building Control — share links, PDF reports, Part L before/after.
Unlimited site workers. No accounts. Free forever — Arqor never charges per worker, so a bigger crew never means a bigger bill.
“Your team's WhatsApp photos won't pass inspection.”
The moment a photo is sent, the time and place are stripped out. SiteRecord keeps the proof intact — the difference between a folder of pictures and real evidence.

Each pillar works on its own — buy just what you need. But these aren't separate apps: the same job carries the site photos, the quote, the invoice, the hours worked and the receipts — which is exactly what makes the AI engine below possible.
Site photo evidence
Timestamped, GPS-tagged photos pinned to the plan — evidence that satisfies Building Control, captured in seconds from a QR scan. Offline-first, Part L before/after, branded PDF reports.

Everything the office side of a trade business runs on, sharing one customer list and one set of numbers — and shaped around your quote style, your numbering, your habits. Running real firms today.
Customers, their sites and their jobs in one record — payment terms, customer types, and a job page that shows the photos, the hours and who’s on site right now.
Branded PDFs with your logo and colours, VAT handled properly, one-click Mark paid — and line autocomplete that learns your phrasing, so quotes write the way you do.
Quoted → Accepted → Scheduled → Invoiced. Drag a quote to Accepted and the job creates itself. Nothing falls down the gap between “they said yes” and “we started”.
The day, week or month at a glance — drag a job onto a day and everyone knows where they’re going.
One-tap clock in and out from the worker app, weekly timesheets, crews, payroll CSV — with per-job labour totals live on the job page. No timesheets to chase.
Every active job on a map with a live headcount, and each on-clock worker’s actual position — never tracked off the clock. Geofenced auto clock-in/out is on the way.
A worker photographs a receipt; the AI reads the supplier, total, VAT and date. The office approves it, the accountant gets a tidy CSV, and job costing gets real.
A full inbox inside Arqor — connect the company Gmail and every email files itself against the right customer. A signature designer builds your signature from your brand, and starter templates written for trades fill the details in themselves.
An append-only payments ledger, CSV bank reconciliation and polite, opt-in overdue reminders under your brand. A live bank feed and pay-by-bank with our open-banking partner Fena are on the way.

Also on the way: per-job messaging, so every conversation — office, crew and client — lives in the job's thread, not five group chats. Want Office early? Join the pilot →
Arqor doesn't bolt AI on. It's built on a connected dataset that makes the AI smarter about your business every week you use it.
Today — it assists
Next — it recommends
Then — it predicts
The AI understands the job; Arqor does the arithmetic.
It never invents a price — totals, VAT and margins are always calculated, and every suggestion is explainable. And while anyone can rent the same AI models, nobody can copy your accumulated history: your estimating, your real job outcomes, your customers. That history lives in your account, isolated per company. Your data is yours.
Established firms run Arqor fully white-labelled: your logo, your colours and your own domain — app.yourcompany.com — across the app, the PDFs, the sign-in emails and the QR surface your clients and subbies see.
A London landscape & maintenance company runs its whole operation on Arqor — office and field — under its own name, on its own domain.
In daily production use on real UK sites since May 2026. Built in the UK, for UK rules: Building Control evidence, Part L and VAT.
Simple, per company. Every tier — including Free — has unlimited QR site workers, GPS and timestamped photos, plan pinning and share links. Prices + VAT.

Office and The Arqor OS (all three pillars, priced as two): being finalised with design partners — join the pilot. Extras: admin seats £25/seat/mo (Pro) · storage £5 per 5 GB.
Operative tickets and cards, expiry tracking and alerts, H&S records — the third pillar. Leave your email and be first to know.
Arqor is the operating system for UK trade and construction businesses — three pillars on one connected dataset: SiteRecord for site photo evidence (live), Office for running the business (live with design partners), and Compliance (coming). The same job carries the photos, the quote, the invoice, the hours and the receipts.
Each pillar is purchasable on its own, or all three together as The Arqor OS — priced as two pillars. SiteRecord starts free — £0 forever, up to 3 active jobs — with paid tiers from £19/month (£15/month billed annually), and every tier includes unlimited free QR site workers. There is a 14-day free trial of everything, no card required. Office and OS pricing is being finalised with design partners — get in touch to join the pilot.
