AI & Automation · Document Processing

AI document processing from inbox to ERP, with checks at every step

We build pipelines that read incoming documents, extract the fields you need, validate them against your vendors, orders and products, and post clean records to your ERP, with uncertain documents sent to a reviewer.

Definition

What is AI Document Processing?

AI document processing is the automated reading of business documents such as invoices, purchase orders, forms, receipts and contracts, using optical character recognition (OCR) and AI models to extract structured data. The extracted fields are validated against existing business records and either posted to a system such as an ERP or sent to a person for review. It replaces manual re-keying, not the judgment of the people who approve financial and contractual records.

Documents arrive as PDFs, scans, phone photos and email attachments in every layout imaginable. Template-based OCR tools break each time a supplier changes their invoice design, so staff end up re-keying anyway. Modern AI models handle layout variation far better, but they can still misread a figure or pick the wrong date, so extraction has to be paired with validation rules and a review step before data touches the books.

Business challenges

Why manual and template-based processing fall short

01

Endless document layouts

Each supplier, customer and government form uses a different layout, which defeats fixed templates.

02

Poor scan and photo quality

Skewed scans, low-resolution photos, stamps and handwriting reduce what any OCR or model can reliably read.

03

Errors with financial impact

A misread amount, tax figure or bank detail posted straight to accounting causes reconciliation problems or worse.

04

Data that doesn't match records

Vendor names, product descriptions and units on documents rarely match your master data exactly.

02

OCR and layout analysis

Text and table recognition for scanned and digital documents, using OCR services or vision-capable models suited to your document types.

03

Field and line-item extraction

Extracting header fields and table rows such as vendor, document number, dates, totals, taxes and line items into a defined schema.

04

Validation and matching

Checking totals add up, matching vendors and products to master data, and comparing against purchase orders or receipts where available.

05

Review interface

A screen showing the document beside the extracted fields, with low-confidence values highlighted for a person to confirm or correct.

06

ERP posting

Creating draft vendor bills, orders or records in Odoo or another ERP, with the original document attached for audit.

Business benefits

What AI Document Processing changes for your business

01

Less re-keying

Staff check and approve extracted data instead of typing it in from scratch.

02

Errors caught before posting

Validation rules flag mismatched totals, unknown vendors and duplicates before they reach the ledger.

03

Searchable document archive

Every record keeps a link to its source document and extracted text.

04

Handles new layouts

AI extraction copes with layout changes far better than fixed templates, reducing maintenance.

Use cases

Where it makes the biggest difference

Vendor bill processing

Supplier invoices extracted, matched to purchase orders and goods receipts, and created as draft bills for accounts payable to approve.

Customer purchase orders

Incoming PDF orders read and converted into draft sales orders with products matched to your catalogue.

Delivery and logistics paperwork

Delivery notes, bills of lading and proof-of-delivery documents digitized and linked to shipments.

Forms and applications

Registration, admission or claim forms extracted into structured records, with handwritten fields flagged for review.

Process

Seven steps from sample documents to live processing

Extraction is measured on your own documents before the build, and a parallel run confirms results before manual entry stops.

  1. Collect samples

    Gather a representative set of real documents, including poor-quality and unusual ones, and the records they should produce.

  2. Define the schema

    Agree exactly which fields to extract, their formats, and the validation rules each must pass.

  3. Prototype extraction

    Test OCR and extraction approaches on the samples and measure field-level results against the correct values.

  4. Build validation

    Implement matching against master data and business rules, and decide what triggers human review.

  5. Integrate

    Connect intake, review and ERP posting on staging, creating records as drafts rather than final entries.

  6. Parallel run

    Process live documents alongside manual entry and compare results before switching over.

  7. Operate

    Monitor review rates and corrections, add new document types, and refine rules as suppliers change formats.

Security, quality and scale

Sensitive data controls

Bank details, identity numbers and personal data can be masked, restricted or processed on self-hosted models.

Draft-only posting

Records are created as drafts so financial entries always pass through a person with posting rights.

Document retention

Storage location, retention periods and access rights for original files are defined to suit your policies.

Provider review

OCR and model providers are checked for data retention and processing terms before any documents are sent.

FAQ

AI Document Processing: questions we hear most

How accurate is AI document processing?

Accuracy depends heavily on document quality, layout variety and which fields you need, so we measure it on your own samples rather than quote a figure. Validation rules and human review of low-confidence fields are what make the overall process reliable.

Can it handle handwritten or poor-quality scans?

Partly. Clear handwriting and reasonable scans can often be read, but faint, skewed or heavily stamped documents reduce reliability, and those fields are flagged for review. Improving capture, such as scanner settings or a mobile capture guide, often helps as much as the model.

Does it work with Odoo?

Yes. We post extracted data into Odoo as draft vendor bills, sales orders or other records through its API, with the source document attached. We can also integrate with other ERPs that offer an API.

Are our documents sent to an external AI provider?

They can be, under provider terms we review with you, or they can be processed with self-hosted OCR and open-weight models if documents must not leave your infrastructure. The trade-off is usually between convenience and running effort.

What does document processing cost to run?

Running cost depends mainly on document volume, page count and the OCR or model services used, plus hosting. We measure cost per document during the prototype so the figure is based on your real documents.
