Define document types and sample files
A pilot for AI document and invoice processing needs more than the cleanest available file. Text PDFs, scans, rotated images, multi-page invoices and missing pages create different failure conditions. List the document types the business actually receives. Have a reviewer prepare expected fields from the source documents; the model’s own output cannot serve as the reference answer.
Separate invoices, purchase orders, delivery documents and credit notes. Similar layouts do not imply the same accounting action. If the type is uncertain, establish how the system pauses and routes the document for review before creating a record. Starting with one supported class can be appropriate; unsupported files should not be counted as successful processing examples.
Use controlled files representing real business layouts without exposing unnecessary supplier or bank details. Keep the source readable for review. Associate filename, sample identity, page count and reference fields in the test set. Do not remove difficult documents to make the pilot appear more accurate. Their failure conditions are part of the acceptance question the business needs to answer.
File conditions
Review text, scan quality, rotation and page completeness separately.
Document class
Invoices, orders and correction documents may require different treatment.
Reference fields
A responsible reviewer verifies expected values against the actual source.
Write field and normalization rules
Create an invoice extraction field dictionary for supplier, date, invoice number, currency, subtotal, tax and total. Describe where a value may appear and the required output format. Agree how absence is represented, such as a blank value with a review reason. A missing date or identifier should not be invented merely because a plausible value would make the record look complete.
Normalization should not silently overwrite source evidence. Keep raw and standardized values comparable where needed. Agree date order, decimal notation, supplier-name variation and currency-symbol treatment with the business. An ambiguous amount or date should be flagged instead of converted through an unstated assumption. The reviewer should be able to explain why a normalized value differs from the printed one.
Keeping the source page or region associated with a field can make correction practical. If a confidence indicator is available, treat it as a signal rather than a guarantee. Required fields, document class and amount relationships also matter. When a field definition changes, track the mapping version expected by the destination, so an old approval does not hide a new interpretation.

Share the document classes, required fields and intended accounting step. We can define scope through controlled samples and a usable human review process.
Check amounts and currency consistency
During invoice extraction validation, check the relationship between the printed total and extracted subtotal, tax, discounts and other charges. Have the accounting owner define rounding and special tax conditions. The expected relationship may depend on document class. Applying a universal addition rule and automatically changing the source total is not a sound way to establish acceptance of every invoice.
Match currency to an explicit document indication. A symbol can represent more than one currency, and the supplier’s country alone is not sufficient evidence. Any conversion needs its own approved rule and data source. The extraction workflow should not independently choose an exchange rate or change the document currency to make downstream fields fit.
Route inconsistent records to a reviewer with a reason: missing line, decimal ambiguity, lost page or unclear currency. The reviewer needs the source and extracted fields together. Preserve the distinction between the first result and a corrected value. Record whether an incorrect amount was prevented from reaching the destination, not just whether someone eventually noticed it.
Test repeated uploads and missing fields
In the document processing pilot, upload the same invoice as the original file, under a new filename and as a fresh scan. A filename alone is insufficient for duplicate checking. Evaluate the business’s document identity rules, including supplier and invoice number where appropriate. Missing identifiers or similar documents may need review rather than automatic deletion; genuinely separate invoices should not be merged by a broad similarity rule.
Test an interrupted upload separately from a delayed destination acknowledgement. On retry, establish the first request’s state before creating another accounting entry. Maintain an operation record distinguishing a repeated request from a new document. Extraction and destination transfer may have separate replay behavior. Inspect both, because a correctly deduplicated upload can still be transferred twice.
Observe where processing stops when a required field is absent. Do not guess an invoice number to fill an empty field. A missing page can leave some amounts visible without making the document complete. The review queue should explain what is missing and what information would resolve it. An unresolved record should remain visibly unresolved rather than be closed as successful output.
Repeated upload
Try the same document through different filenames and image versions.
Distinct invoice
Check that legitimate separate records are not blocked by superficial similarity.
Missing field
Record a review reason and owner instead of inventing the absent value.
Verify human review and approval
Place the source, extracted fields and exception flags together in the invoice extraction review task. A reviewer seeing only an AI summary cannot compare it with the document. Record approval, correction and rejection as distinct actions. Make the approved version identifiable; generating a new extraction should not automatically carry the previous approval onto a changed set of values.
Separate permission to read a file from authority to approve accounting treatment. Do not assume the uploader or technical support person can make that decision. Use controlled roles to check that an unauthorized reviewer cannot approve a record. Explain the pending state to users. The accounting team should decide when a corrected value requires another review.
Include access and retention in the acceptance matrix. Invoices may contain supplier and banking information, which should stay out of public example screens. Identify the locations of archives, extracted outputs and error copies. Control unnecessary duplicates and follow the business’s applicable retention policy. Technical convenience should not silently determine how long each copy is kept or who can inspect it.
Separate accounting transfer from payment authority
Within a document processing workflow, JSON demonstrates structured field output. Separately test whether the accounting destination accepts the mapping, creates the intended status and preserves the approval boundary. Examine supplier matching and transfer errors. A working connection does not establish the complete accounting workflow. Keep extraction acceptance and destination acceptance distinguishable so their owners can investigate failures without conflating them.
Preparing and executing payment require authority beyond reading an invoice. A community workflow example does not grant that authority for your business. A pilot might stop at a review queue or draft entry. Document the selected boundary and the responsible approver. The existence of a technical action button should not be treated as permission to move money.
Include sample identity, document class, expected field, observed field, consistency result, duplicate status, reviewer and destination outcome in the acceptance file. Classify extraction defects separately from transfer defects. After correction, rerun the same sample and check that no unwanted new record appears. State which stages were accepted and which remain untested rather than describing the entire process as approved.

BEFORE YOU DECIDE
Frequently asked questions
Are OCR and document automation the same?
OCR covers reading text or fields. Document automation can also include classification, validation, review and transfer. Acceptance of the reading stage does not demonstrate that the other stages are working.
What happens when an amount is extracted incorrectly?
Route an inconsistent or uncertain amount to human review. Preserve the source total, the reason for correction and the approved version. Do not silently modify the document’s meaning to reconcile the output.
How should repeated invoices be handled?
Use the business’s document identity rules as well as file information. Flag possible duplicates where judgement is needed. Re-uploading should not create another accounting or payment entry.
Does JSON output mean accounting integration?
No. JSON is structured output. The destination’s mappings, record status and error handling require separate integration tests before an accounting transfer can be accepted.
Should payment execution be automatic?
Extraction does not grant payment authority. If payment actions are in scope, define the responsible person, approval conditions and operation boundaries separately. They should not be enabled by assumption during a reading pilot.
