Intelligent Document Processing & Document AI Services

We build intelligent document processing pipelines that classify what arrived, extract the fields that matter, validate them against your rules, and push the result into the system that owns the next step — with a human review path for anything the pipeline is not confident about.

Where This Starts

The documents that need a person to move them

Document work is expensive precisely because it looks trivial: read this, type that somewhere else, decide where it goes.

Invoices arrive in every format imaginable

PDF, scan, phone photo, email body — each vendor different, and someone keys them into the finance system by hand.

The OCR tool you bought only half worked

It reads clean documents fine and fails on anything with tables, multi-column layouts, or handwriting, so a person still checks everything.

Field paperwork gets re-typed at the office

Inspection sheets and job reports come back from site as photos or scans, then get manually transcribed into the system of record.

Contract terms live only in the PDF

Renewal dates, payment terms, and liability caps are locked inside documents nobody can query, so they are tracked in a parallel spreadsheet.

Volume grew but headcount could not

The process worked at fifty documents a day. At five hundred it is a backlog with a growing error rate.

Nobody can prove why a value was entered

An audit asks where a figure came from, and the answer is that someone read it off a document that may or may not still be findable.

The Pipeline

How a document becomes a system record

Each stage is instrumented separately, so when accuracy drops you know which stage caused it.

01

Classify

Identify the document type and route it to the right extraction schema before reading any fields.

02

Extract

Pull the fields that matter into structured output, with a confidence score attached to each value.

03

Validate

Check values against your own systems and business rules — not just whether text was read, but whether it makes sense.

04

Review

Anything below threshold goes to a human queue with the source document and extracted values side by side.

05

Route

Validated output posts to the owning system, with the original document linked to the record it produced.

Document Types

Workflows we build most often

The pipeline is the same shape each time. What differs is the schema, the validation rules, and where the output lands.

Accounts payable and invoices

Vendor invoices matched against purchase orders and receipts, with exceptions surfaced rather than guessed.

  • Line-item extraction
  • PO and receipt matching
  • Duplicate detection

Orders and purchase documents

Inbound orders read from PDF or email and turned into system records without manual entry.

  • Order header and lines
  • Customer and SKU resolution
  • Exception queues for unknowns

Contracts and agreements

Key terms extracted into a queryable form so renewals and obligations stop living only inside the document.

  • Dates, terms, and parties
  • Clause identification
  • Obligation tracking

Field and inspection reports

Site paperwork and photos captured and structured, so the office does not re-type what the crew already wrote down.

  • Handwritten form capture
  • Photo evidence linking
  • Asset and job association

Identity and compliance documents

Onboarding and verification packs checked for completeness and validity before they reach a reviewer.

  • Completeness checks
  • Expiry validation
  • Redaction of sensitive fields

Technical and engineering documents

Specifications, drawings, and datasheets made searchable and queryable across a document estate.

  • Table and spec extraction
  • Cross-document search
  • Revision tracking
Approach

Classic OCR, multimodal models, and where each wins

Most production pipelines use both. Choosing one for everything is how projects end up expensive and inaccurate at the same time.

Classic OCR + rulesMultimodal / LLM extraction
Best onFixed templates, clean scans, known layoutsVariable layouts, mixed formats, unseen vendors
Tables and layoutReliable when the template is stableHandles shifting structure without a template
HandwritingWeak outside constrained formsConsiderably better, still needs review
Cost per pageVery lowMeaningfully higher — matters at volume
ExplainabilityDeterministic and easy to traceNeeds confidence scoring and source linking
Typical roleHigh-volume known formatsThe long tail everything else falls into
Accuracy

How accuracy is established and kept

Nobody can quote you an accuracy figure before seeing your documents. Here is how we get to a number you can rely on.

Measured against your own labelled sample

We build an evaluation set from your real documents, including the awkward ones. Accuracy is reported per field, because a pipeline can be excellent at dates and poor at line items.

Confidence thresholds you control

You choose the trade-off between automation rate and review volume. A stricter threshold means more human review and fewer errors reaching your systems.

Review queues that improve the system

Corrections made by reviewers become evaluation cases, so the queue is a feedback loop rather than a permanent tax.

Regression testing before every change

Model and prompt changes run against the full evaluation set first, so an improvement on invoices cannot silently break contracts.

Where Output Lands

Systems we push structured data into

Extraction that ends in a CSV is a demo. The value is in the document arriving as a record in the system that owns the process.

Security

Handling documents that contain sensitive data

Data residency and model routing

Where documents cannot leave a jurisdiction or a network boundary, we route to models that satisfy that constraint, including self-hosted where required.

Redaction before processing

Fields you do not want sent to a third-party model can be masked before extraction, with the redaction applied at ingestion rather than after.

Retention and audit trail

Every extracted value links back to the source document and the run that produced it, so an auditor can trace a figure to its origin.

Access control on review queues

Reviewers see only the document classes their role permits, which matters when the same pipeline handles finance and HR documents.

How We Work

From a sample of documents to a running pipeline

Step 01

Document workflow assessment

We look at real samples across your formats, map what happens to them today, and establish what accuracy would need to be to remove manual work.

Step 02

Evaluation set and baseline

A labelled sample becomes the benchmark. You get a measured per-field accuracy figure before committing to a full build.

Step 03

Pipeline build and integration

Classification, extraction, validation, review queue, and the integration into the system that receives the output.

Step 04

Tune thresholds and hand over

Confidence thresholds set against your tolerance for review volume, with monitoring you can read without us.

Engineering

What we build with

Model and tooling choices follow the document types. Most production pipelines combine several rather than betting on one.

FAQ

Questions buyers actually ask

IDP is the pipeline that takes documents arriving in any format and turns them into structured data inside your business systems: classify the document type, extract the relevant fields, validate them against your rules, route low-confidence cases to a human, and post the validated result to the system that owns the next step. The distinction from plain OCR is that OCR reads text, while IDP produces validated, structured output that a system can act on.
Nobody can answer that honestly without seeing them, and you should be sceptical of anyone who quotes a figure up front. Accuracy varies enormously by document type, scan quality, and field — a pipeline can be near-perfect on dates and totals while struggling with line items on poor scans. We build an evaluation set from your real documents and report per-field accuracy before you commit to a full build.
OCR converts images of text into text. It does not know what the text means, whether a value is plausible, or where it should go. IDP uses OCR or multimodal models as one stage, then adds classification, schema-aware extraction, validation against your own data, confidence scoring, human review, and integration. If your OCR tool produces text that a person still has to read and re-key, the missing pieces are the ones that matter.
Usually yes, and that is the correct design rather than a failure. You set a confidence threshold that trades automation rate against review volume. Most pipelines automate the routine majority and route the ambiguous minority to a reviewer, which is both cheaper and safer than forcing full autonomy. Corrections reviewers make feed back into the evaluation set.
Better than classic OCR, but with realistic limits. Multimodal models handle handwriting and awkward layouts considerably better than template-based OCR, and we combine approaches rather than relying on one. Genuinely poor scans and free-form handwriting will still need review — we establish where that line sits for your documents during the assessment rather than promising it away.
In whichever system owns the process — SAP, NetSuite, QuickBooks, Xero, Salesforce, a custom database, or your data warehouse. The integration is part of the build, not a separate project, and the original document is linked to the record it produced so the value can always be traced back to its source.
A single document type with one target system typically takes 6 to 10 weeks, including the evaluation set and integration. Multiple document types, or targets with restrictive APIs, extend that. We deliver the evaluation and baseline accuracy early so you can make the go or no-go decision before the bulk of the spend.
