AI Systems
Document AI: production AI systems built in the UK
In short
Document AI that extracts, classifies and routes invoices, dockets, contracts and PDFs at scale — with structured output your systems can actually consume. Production document processing pipelines that ingest PDFs, scans, emails and photos, extract the fields you care about, validate them against your rules and hand structured data to your ERP, CRM or accounting system.

Why UK operators are buying document ai in 2026
UK operators still process most of their inbound paperwork by hand. Modern LLMs and vision models turn a 4-minute manual step into a 4-second automated one — accurately enough to run in production.
Workflows we automate
Purchase invoice processing, delivery docket capture, contract review, expense processing, KYC document handling, insurance claims intake, tender response analysis.
The stack we build on
GPT-4o Vision, Claude 3.5 Sonnet, Gemini 1.5 Pro, plus open-source layout models (LayoutLM, Donut) for private-data workloads. Output goes to Xero, Sage, QuickBooks, SharePoint, Google Drive, DocuSign or your own database.
Real document ai use cases
• Purchase invoice capture from email attachments straight into Xero with line-item coding and supplier matching. • Delivery docket capture from photos taken on-site, matched against POs and posted to the ERP. • Contract review that surfaces unusual clauses, non-standard payment terms and missing signatures before a human reads the doc. • Insurance claims intake that reads the FNOL email, extracts the incident details and opens the case in the claims platform. • Tender response analysis — reading a 200-page ITT and producing a scored bid/no-bid summary for the leadership team.
Outcomes to expect
Typical accuracy in the 95–99% range on well-defined fields, with human review only on the tail. Processing cost per document drops from £0.80–£2.50 (manual) to £0.02–£0.10 (AI).
Pricing
£499 AI Ops Audit to size the volume and accuracy target. £2,500 Sprint to ship the first pipeline. £6,000/month embedded for scaling coverage across document types.
Timeline
First production document type live in two weeks. A full accounts-payable-grade pipeline across all invoice formats typically ships in 6–10 weeks.
How we engage
Every document ai engagement starts with our £499 fixed-price AI Ops Audit. That produces a scored, costed 30/60/90 day plan you own — whether you build with us or not. If you proceed, we ship the first production system in a two-week £2,500 Sprint, then continue on a rolling £6,000/month embedded build partnership. Delivered from Edinburgh, UK, with named engineers — never an offshore pool.
