03 Design
Why set the threshold per field?
Because the fields are not equally dangerous. One threshold across a document either wastes review effort on the safe fields or lets the risky ones through, and both are avoidable.
| Field | Measured accuracy | Cost of an error | Threshold we set |
|---|---|---|---|
| Invoice amount | 99.2% | A wrong payment | High, plus a rules cross-check on the arithmetic |
| GSTIN | 97.4% | A blocked input tax credit | High, plus format and checksum validation |
| Vendor name | 71.8% | A misposted ledger, easily spotted | Always review, until accuracy improves |
| Invoice date | 98.6% | A wrong ageing bucket | Medium, with a sanity range check |
| Line description | 88% | Almost none | Permissive, no review |
Step 1: Measure per field
On 50 to 200 of your own documents, with the correct answer defined by your team rather than by us.
PilotStep 2: Price the error
What a wrong value actually costs, which is a business judgement and yours to make. We supply the accuracy and the review load each choice implies.
DecisionStep 3: Add the rules layer
Format checks, checksums, arithmetic that must tie and range sanity tests. A model should never be the thing that adds up a column.
BuildStep 4: Staff the review queue
A real queue with a named owner, a service level and escalation, exactly as an approval workflow would have.
BuildStep 5: Watch the review share
A rising proportion below threshold is the earliest warning that the document mix or the provider model has changed.

04 Governance
The two rules that follow the data
Both are cheaper designed in than retrofitted, and both are questions an audit or procurement team will eventually ask in writing.
- Personal data. Documents contain names, phone numbers, addresses and bank details, and sending them to a model is processing them. The Digital Personal Data Protection Rules, 2025, notified on 13 November 2025 by the Ministry of Electronics and Information Technology, apply, with the main obligations commencing on 13 May 2027.
- The accounting record. Anything posting entries is part of the accounting system and inherits the Rule 3(1) audit trail obligation administered by the Ministry of Corporate Affairs, in force since 1 April 2023, with the eight financial year retention Section 128(5) of the Companies Act, 2013 requires.
- What we put in writing before a pilot. Which provider, which region, whether inputs are used for training, what retention applies, and what never leaves your systems at all.
05 Reference
Terms used on this page
- Intelligent document processing
- Written IDP: extracting structured fields from documents that arrive in no fixed layout.
- Confidence threshold
- The level below which an output is sent for human review instead of being accepted. Set per field, from the cost of an error.
- Review queue
- Where below-threshold output goes, with a named owner, a service level and escalation.
- Straight-through rate
- The share of items processed with no human touch. The number that decides whether the automation pays back.
- Drift
- Behaviour changing over time, either because the provider updated the model or because the incoming documents changed.
- Audit trail
- A non-erasable log of each entry and each later change with its date, required of company accounting software since 1 April 2023.
- Data Protection Board of India
- The adjudicating body under the Digital Personal Data Protection Act, 2023. The Schedule to that Act sets fixed rupee ceilings rather than a share of turnover: up to ₹250 crore for failing to take reasonable security safeguards against a personal data breach, up to ₹200 crore for failing to notify the Board and the people affected, and up to ₹50 crore for a breach of any other provision. That is why consent, retention and access control are build decisions here rather than paperwork.

We will pilot it on your own documents and come back with a measured accuracy figure per field, a cost per item, and the review load it implies.
