Enterprise SaaS
Document automation on a specialised SaaS product
A specialised document-automation product — Rossum, Nanonets, Mindee or an equivalent — connected to your systems, scoped by your identity provider, covered by a DPA, with a human-validation step and an audit trail. The vendor runs the model and the extraction; you own the contract and the integration.

01Objective
Automate extraction for a common document type using a finished vendor product, with the contract, identity and validation controls that make it defensible — and no pipeline to build.
- use caseData extractionPulling defined fields out of unstructured text into a schema — from forms, reports, emails, filings or web pages. The general case of invoice extraction, and the step that turns documents into something a database can hold.
- use caseDocument classificationSorting incoming documents into types and routing them — which team, which folder, which workflow, which retention rule. Usually the first step of a larger pipeline and the cheapest place to remove manual handling.
- use caseInvoice extractionReading supplier invoices — header fields, line items, tax, totals — into structured records. The extraction step only. What happens to the record afterwards is invoice processing automation.
- use caseInvoice processing automationThe whole accounts-payable path: capture, extraction, supplier matching, purchase-order and goods-receipt matching, approval routing, and posting to the finance system. Extraction is one step of it; exceptions are where the work actually is.
- use caseOCRTurning images of text — scans, photographs, faxes, historic files — into machine-readable text with layout. The step everything else depends on: no extraction, search or classification pipeline is better than the text layer underneath it.

External data transfer · YES
- confidential content leaves your control on the Finance / operations team (validation) → Document-automation product link.
- confidential content leaves your control on the Your accounting / ERP system → Document-automation product link.
- Documents, extractions and the audit trail are processed by the vendor under contract. What the vendor does with them is a matter for the DPA and the plan, not the architecture.
- The one flow back into your premises is the validated records posted into your own accounting or ERP system, which is not a transfer out.
03Suitable for
- Organisation size
- 50–20000 employees
- Data classes
- confidential, personal
- Constraints
- a common, well-defined document type the vendor already reads well; agreement that documents may be processed by the vendor under a DPA; a system to post the validated records into, and someone to own the vendor relationship

Indicative costUSD · one-off plus monthly
- Product licence
- Not estimated. These products are priced per document, per page or per tier and no price was fetched. Get a quote for your document volume; the licence is the largest cost and only the vendor can price it.
- Not estimated
- Model usage
- Not estimated separately: the model and the extraction are bundled into the product licence rather than metered to you. The vendor runs and prices the model.
- Not estimated
- Implementation (5–14 FDE-days)
- 5–14 FDE-days at US$760–1940 per day, converted from the HK$6,000–15,000 band at the HKMA Linked Exchange Rate band of HK$7.75–7.85 to one US dollar. One-off; excludes internal staff time.
- US$3,800 – US$27,160
- Implementation is the integration and the rollout: connecting the arrival channel and the target system, SSO, the validation workflow and a pilot — not building an extractor.
- Assumes an identity provider and a target accounting or ERP system already exist.
- The total is deliberately incomplete: the per-document licence is the largest cost and only the vendor can price it for your volume.

07Deployment steps
Commands are copied from each project’s own documentation, and the page they came from is linked under the step. 0 of 7 steps currently open an evidence record. The rest are linked to their source; §10 says which of those documents were fetched and which were fetched without their anchor being found — two different states, named differently there.
- 01
Shortlist on the document type and the terms
AssessmentWrite down the document type, the fields, the arrival channel and the target system, then ask each vendor the same questions. The products describe broad coverage — Mindee’s "AI-driven OCR API provides high-precision data extraction for all document formats", Rossum’s agents "read documents, capture, validate, and transform data, send emails, ask for approval" — but a published claim is where the evaluation starts, not where it ends. Test on your own documents.
- 02
Evaluate on your own documents before signing
AssessmentSend a representative, labelled set through each shortlisted product and measure field-level accuracy — the vendor’s benchmark is not evidence about your suppliers, your formats or your handwriting. Mindee describes turning "your document data into structured JSON"; the test is whether that JSON is right for your documents, and at what confidence.
- 03
Get the DPA, the subprocessors and the residency in writing
AssessmentAsk for the data processing agreement, the current subprocessor list, where processing happens, and the retention and deletion terms. Vendors describe security postures — Rossum states it meets "the highest industry standards, ensuring the confidentiality of your documents" — but that is a starting point for the contract, not a substitute. Get the commitments into the agreement.
- 04
Confirm encryption, key management and the audit trail
AssessmentCheck how documents are encrypted and who holds the keys. Nanonets, for example, states "AES-256 at rest, TLS 1.3 in transit. BYOK supported for customer-managed keys", and that "every agent run, approval, and data access is recorded, and streams to your SIEM". Confirm the equivalents for the vendor you choose, and that you can export the audit trail.
- 05
Connect the arrival channel and the target system
AssessmentWire the mailbox or folder documents arrive in, and the accounting or ERP system the validated records post into. This integration is most of the work and most of the value: a product that reads perfectly but cannot post into your ledger has automated the easy half.
- 06
Keep a human validation step, and set the confidence threshold from data
AssessmentThese products are built around review: Rossum’s agents "capture, validate, and transform data" and "ask for approval". Keep the validation queue, set the auto-accept threshold by measuring accepted-and-wrong against reviewed-and-right on a labelled sample, and keep the corrections — they are the record that the automation is improving.
- 07
Confirm the compliance posture and put the vendor on a review cycle
AssessmentNanonets states it "meets the highest industry standards for your security & compliance"; treat every such claim as a question for the security review rather than an answer. Diary a quarterly check of the subprocessor list, the retention terms and the audit export, and re-read the terms at renewal.
08Compliance considerations
Structured issue-spotting to support your own review — not legal advice. Verify against the cited primary sources and your counsel.
Applies everywhere
Data processing agreement · Subprocessors · Vendor jurisdictionhigh
A processor agreement is the foundation. Get the DPA, the subprocessor list and the contracting entity, and confirm how you are notified when a subprocessor changes. Rossum states it protects the confidentiality of your documents — get that into the contract, not just the website.
Data residency · Cross-border transfershigh
Establish where documents are processed and stored, not only where your tenant is. For a residency rule, confirm the region in the contract and check whether support access or a subprocessor sits outside it.
Security · Confidentialityhigh
Check encryption at rest and in transit, and whether customer-managed keys are supported. Nanonets states AES-256 at rest, TLS 1.3 in transit and BYOK; verify the specifics for your chosen vendor rather than assuming parity.
Human oversight · Automated decision-makinghigh
Keep the validation step. Where an extracted value drives a decision about a person, auto-accepting on the vendor’s confidence alone is an automated decision — set the threshold deliberately and keep a person in the loop for the exceptions.
Logging · Auditability · Retentionmedium
Confirm the audit trail records runs, approvals and data access, that you can export it, and how long the vendor retains documents and records. Nanonets streams its audit trail to a SIEM; check whether your vendor offers the equivalent.
09Alternatives
Build it in your own cloud account
When the document type is unusual or the schema keeps changing, a managed extraction service plus a model in your own account gives more control than a finished product — at the cost of building the pipeline.
- — Full control over the schema, the model and the review logic
- — You build and run the pipeline instead of buying it

Self-hosted, if documents may not leave the network
Where confidentiality rules out a processor, run OCR and the model on your own machines and remove the vendor from the data path entirely.
- — No vendor sees the documents
- — You own the GPU, the operations and the accuracy
- Self-hostedInvoice capture and extractionInvoices arrive by email or watched folder, Docling converts them (OCR included), a local vision-capable model fills a JSON schema under constrained decoding, code checks the arithmetic and the supplier against your master data, and n8n posts the clean ones while routing the rest to a person.
- Private cloudDocument extraction pipeline in your cloud accountA landing zone in object storage, a managed document-understanding service (Azure AI Document Intelligence, Amazon Textract or Google Document AI), a managed model constrained to a JSON schema, validation in code, and a confidence-thresholded review queue — all in the region you pin, reached over private networking.
