Intelligent Document Processing
Intelligent document processing that turns invoices, forms and contracts into checked data
We build document pipelines that classify incoming files, extract the fields you need, check them against your own records and rules, and send only the uncertain cases to a person. Approved data then flows into your ERP, accounting or case system, with a record of every value and every correction.
Documents in, structured data out.
The problem
The problem it solves
Intelligent document processing (IDP) is the automated capture of data from documents such as invoices, forms, contracts and shipping papers. It combines OCR, layout analysis and language models to classify each document, extract fields and tables, validate them against business rules and reference data, and route low-confidence results to people for review before the data reaches business systems.
Documents are still how organisations exchange commitments with suppliers, customers and partners, and most arrive as PDFs, scans, phone photos and email attachments. Someone has to read each one and re-key the data, and that step quietly sets the pace for payments, shipments and onboarding behind it.
- 01Accounts payable staff retype invoice headers and line items into the ERP, then chase differences with purchase orders over email.
- 02Suppliers and partners each use their own layouts, so template-based OCR needs rework every time a new format appears.
- 03Stamps, handwriting, skewed scans and tables that run across pages defeat basic text extraction and produce silent errors.
- 04Mistakes surface at payment, customs clearance or audit, when they are slowest and most expensive to correct.
- 05Trade paperwork such as bills of lading, packing lists and commercial invoices must agree with one another, and checking that by eye is slow and error-prone.
- 06There is no reliable record of which values were captured automatically, which were changed and who approved them.
Who it is for
Built for teams like yours

Teams that need parties, dates, renewal terms and obligations from signed agreements captured into a register they can search and report on.
Solution architecture
How it fits together
A dependable IDP system is a chain of narrow, observable stages rather than a single model call. Each stage stores its output and a confidence score, so a wrong value can be traced to the step that produced it and corrected there.
- 01
Intake
Shared mailboxes, upload portals, SFTP folders, scanners and APIs feed one queue, with duplicate detection and file normalisation on arrival.
- 02
Classification and splitting
Each file is identified by document type, and bundled PDFs are split into separate invoices, forms or shipping documents before extraction.
- 03
Extraction
OCR and layout analysis read text, tables, checkboxes and stamps, then language models map the content to your schema, including line items and free-text clauses.
- 04
Validation
Arithmetic checks, business rules, reference data lookups and cross-document matching, such as invoice against purchase order and goods received note.
- 05
Human review
A review screen showing the source page beside the extracted fields, with low-confidence values and failed checks highlighted and every correction recorded.
- 06
Integration and audit
Approved data posted to ERP, accounting, transport management or case systems through APIs, with the file, values, corrections and approvals stored together.
Workflow
From request to result
- 01
A document arrives
A supplier emails an invoice, a customer uploads a form or a partner sends a shipping pack, and the file is queued with its source and time of receipt.
- 02
Classify and extract
The pipeline identifies the document type, reads the layout and captures header fields, tables and clauses into a defined structure, scoring confidence for each field.
- 03
Validate against your data
Totals are recalculated, supplier and customer records are matched, orders and receipts are compared and dates are checked against your rules.
- 04
Route by confidence
Documents that pass every check continue automatically, while uncertain or inconsistent ones go to the right reviewer with the exact problem shown.
- 05
Post and archive
Approved data is written to the target system, and the document, its data, any corrections and the approval are archived as one record.
- 06
Review exceptions weekly
Corrections and exception reasons are analysed with the process owner and turned into new rules, prompt changes and evaluation cases.
Capabilities
What the solution includes
Invoice and accounts payable capture
Supplier details, invoice numbers, dates, tax and VAT lines, line items and payment details extracted and matched to purchase orders and goods received notes.
Form and application processing
Structured and semi-structured forms read field by field, including checkboxes, signature presence and legible handwritten entries.
Contract term capture
Parties, effective and expiry dates, renewal and termination terms, payment terms and liability clauses captured into a register, each linked to the clause it came from.
Trade and shipping documents
Bills of lading, packing lists, commercial invoices and certificates of origin extracted and cross-checked for matching consignees, quantities, weights and container numbers.
Cross-document reconciliation
Values compared across related documents and against system records, with the specific field that disagrees flagged for the reviewer.
Field-level review thresholds
Confidence thresholds set per field and document type, so amounts and bank details receive closer scrutiny than low-risk reference fields.
English and Arabic documents
Pipelines for English, Arabic and mixed-language files, tested on your own samples before scope is agreed, since accuracy varies by script and print quality.
Extraction evaluation
Ground-truth sets built from your historical documents that score accuracy field by field on every change to prompts, models or rules.
Benefits
What changes for your organisation
Review instead of retyping
Staff check the exceptions the pipeline cannot resolve instead of keying every field of every document.
Errors stopped at the door
Validation runs on arrival, before a wrong amount or quantity reaches a payment run, a shipment or a report.
Shorter processing cycles
Invoices, claims and shipping packs move to the next step as soon as they pass their checks, without waiting in an inbox.
Evidence for every value
Each figure links back to the region of the page it came from and to anyone who changed or approved it.
New layouts without new templates
Model-based extraction copes with unfamiliar supplier formats, while rules and review catch what it gets wrong.
Clear view of document operations
Dashboards show volumes, exception reasons and queue age by document type and source.

Intelligent Document Processing FAQ
Frequently asked questions
OCR converts an image of text into characters, while intelligent document processing turns a document into checked, structured data. IDP uses OCR as one step, then adds layout analysis to understand tables and fields, classification to recognise the document type, language models to map content to your schema, validation against your rules and records, and human review for uncertain values. OCR alone gives you text; IDP gives you data a system can act on.
Yes, modern IDP reads invoices by understanding their content rather than relying on a fixed template for each supplier. Language models and layout analysis locate the invoice number, totals and line items wherever they sit on the page. New layouts are still worth watching, so we track accuracy by supplier and add supplier-specific rules where a format repeatedly causes errors, rather than building templates up front for every sender.
Accuracy depends on your documents, so we measure it on your own samples before committing to a scope rather than quoting a general figure. PDFs generated by accounting systems are the easiest case, while dense tables that run across pages and low-quality images are harder. We score accuracy field by field against a ground-truth set, then set review thresholds so that values the system is unsure about are always checked by a person before they are used.
Partly, and we test it on your own samples before agreeing scope. Printed text on reasonable scans is read reliably, and clear handwriting in boxed form fields can often be captured. Joined-up handwriting, faint carbon copies, stamps over text and low-resolution phone photos are harder, so those fields get stricter confidence thresholds and usually go to a reviewer. Where you control intake, scanning guidance or an upload screen that rejects blurred images improves results before extraction starts.
Three-way matching compares each supplier invoice with its purchase order and the goods received record before it is approved for payment. The pipeline extracts invoice lines, retrieves the order and receipt from your ERP and checks supplier, quantities, unit prices and totals within the tolerances you set. Fully matched invoices proceed automatically, and mismatches go to accounts payable with the differing lines highlighted, so staff resolve the problem instead of searching for it.
Yes, trade documents are a strong fit because they follow recognisable structures but vary widely between carriers and shippers. We extract shipper, consignee, notify party, ports, container and seal numbers, package counts, weights and goods descriptions, then cross-check them against the commercial invoice, packing list and your booking records. Discrepancies are flagged before documents are submitted or goods are released, when they are cheapest to correct.
Yes, IDP can capture parties, dates, renewal and notice periods, payment terms, liability caps and other clauses you specify into a structured contract register. Each value links back to the clause it came from, so legal or procurement staff can verify it in one click. Because contract language varies, we treat extracted terms as a draft for review and measure accuracy clause type by clause type on your own agreements.
Documents go to review when any field falls below its confidence threshold or any validation check fails. Thresholds are set per field and document type with the process owner, so bank details and totals are held to a stricter standard than a reference number. Reviewers see the page beside the extracted data with the problem highlighted, and their corrections are logged and reused to improve rules and evaluation sets.
Yes, once a document passes validation or review, the data can be posted through your ERP or accounting system's API, a supported import format or an integration service we build. We match records against existing suppliers, customers and cost codes before posting, use idempotent writes so a retry does not create a duplicate, and log each transaction. Where a system has no usable API, we agree a controlled file-based import instead.
Documents are encrypted in transit and at rest, stored in the cloud account and region you choose and visible only to roles that need them. Review screens can mask bank account and identity numbers for reviewers who do not need to see them, and fields a step does not use can be removed before a model call. Model providers are used under enterprise terms that exclude training on your data. Retention rules delete source files on your schedule, and every view and change is logged.
Yes, both are standard validation checks in an accounts payable pipeline. Each invoice is compared with those already processed on supplier, invoice number, date and amount, including near matches where a number was retyped slightly differently. Bank details on the invoice are compared with the supplier master record, and any difference holds the invoice and alerts finance, because changed payment details are a common sign of invoice fraud. A genuine change is then confirmed through your own call-back procedure.
Buy a packaged product if your documents are common types, your volumes are steady and its built-in connectors reach your systems. A custom pipeline makes sense when documents are unusual or multilingual, validation depends on your own data and rules, review must fit an existing workflow, or per-page licence fees grow too fast with volume. We compare both options against your real documents during discovery and recommend the cheaper one that meets the requirement.
Timelines depend on the number of document types, how varied and clean your samples are, the validation rules required and the systems the data must reach. A first release covering one high-volume document type, such as supplier invoices into one ERP, is a sensible starting point and gives measurable results early. Further document types are added in stages, each with its own evaluation set and review settings.
Build cost depends on scope, and we give a fixed quote after a discovery phase in which we test extraction on your sample documents. The main drivers are the number of document types, validation complexity, review screen requirements and integrations. Running costs come from OCR and model processing per page, hosting and storage, and we estimate them from your monthly volumes so you can compare them with the cost of manual handling.
