Your largest document backlog may be a good automation opportunity. It may also contain several different problems: missing information, inconsistent supplier formats, poor scans and approval delays.

Before commissioning a solution, separate those problems. Extracting fields faster will not resolve an unclear approval process or missing purchase-order data.

The first pilot should answer a commercial question: can automation reduce the total effort required to complete a defined workflow, at an acceptable cost and error rate?

That requires a bounded document family, representative samples and a clear destination for the extracted information. The aim is to learn enough to make an informed investment decision.

Start with the completed business task

Define what “processed” means before comparing tools.

For a supplier invoice, the task might include identifying the supplier, extracting line items, matching a purchase order, resolving discrepancies and preparing a draft accounting record. Reading the invoice is only one step.

Record the current process:

  • How many documents arrive and through which channels?
  • How much handling time does each document require?
  • Which fields or decisions cause the most rework?
  • What information must be obtained from another system?
  • Who reviews exceptions and approves the result?

Use this baseline to identify where automation could help. A workflow with modest volume but substantial repetitive handling may offer more value than a large queue whose main delay is waiting for approval.

Assess the documents you actually receive

Build your evaluation around production samples, including difficult cases.

Native digital PDFs can provide accessible text, but they may still contain confusing reading order, unusual tables or missing fields. Scanned documents and photographs introduce different challenges, such as skew, blur and handwriting.

Neither category should determine the decision alone.

If most of the business value lies in scanned forms, excluding them from the pilot could produce a technically successful demonstration that proves little about the real opportunity. Instead, define a manageable subset and test whether its quality is sufficient for the intended task.

Group samples by source, layout and condition. Include documents that previously caused corrections, rather than selecting only clean examples.

Measure variation within the document family

“Supplier invoices” is a business category, not a guarantee of consistent structure.

Some suppliers use stable layouts. Others change table headings, combine several orders or include credits and additional charges. Even one supplier may send revised documents that resemble earlier versions.

Document the variations that affect interpretation:

  • Different names for the same field.
  • Multiple currencies or date formats.
  • Tables continuing across pages.
  • Missing identifiers.
  • Credit notes and corrected versions.
  • Narrative conditions that affect processing.

Select a pilot scope broad enough to represent useful work, while remaining specific enough to investigate failures. For example, one business unit and a defined group of suppliers may provide a clearer starting point than every incoming finance document.

Choose a controlled downstream action

Decide what the pilot is authorised to do with its output.

An initial implementation might prepare draft records for review, populate a staging queue or suggest matches against existing orders. That lets the team evaluate extraction and workflow behaviour before granting authority to post transactions.

Staging does not remove every risk. Reviewers can still approve incorrect data, and draft records can trigger other processes if integrations are poorly understood.

Map the downstream effects explicitly. Identify which actions change inventory, create financial commitments, notify customers or update authoritative records. Keep those actions behind the appropriate approval and validation controls.

NIST’s AI Risk Management Framework provides broader, voluntary guidance for incorporating trustworthiness into AI design, use and evaluation. The pilot-selection method here is a practical scoping approach, rather than a NIST-prescribed checklist. [1]

Hypothetical example: supplier invoice preparation

Consider a distributor comparing two candidates: a mixed archive of historical invoices and current invoices from a small group of recurring suppliers.

The team selects current invoices because it has an operational owner, accessible purchase-order records and a measurable preparation task. The sample includes both digital PDFs and scans.

The pilot extracts supplier details, invoice references, amounts and line items, then prepares a draft record for review.

During testing, an invoice includes a packaging charge alongside goods. The system incorrectly treats it as an inventory item. A reconciliation check may identify the problem, but matching totals alone cannot prove the classification is correct.

The review interface therefore shows the original document beside the proposed fields and highlights unmatched or ambiguous lines. The reviewer corrects the classification, and the case enters the regression set.

The learning is specific: the pilot needs better handling of additional charges. It does not justify declaring the entire document family unsuitable.

Agree on acceptance criteria before development

A single overall accuracy percentage can hide errors in important fields. Evaluate the consequences of mistakes alongside their frequency.

Agree on how you will measure:

  • Critical-field correctness: Check supplier identity, invoice number, currency and other fields that determine downstream actions.
  • Document completion: Measure how many documents reach an acceptable draft state without correction.
  • Review effort: Measure the time spent checking and correcting results.
  • Exception workload: Track the frequency, causes and handling time of cases requiring intervention.
  • Integration behaviour: Test duplicate handling, interrupted requests and recovery without unintended records.
  • Operating cost: Calculate processing, infrastructure and human review cost per completed document.

Agree thresholds according to document variability and business consequences. A small initial sample can expose obvious defects, but it does not establish production reliability.

Keep evaluation documents separate from those used to tune the system, and expand testing as new variations appear.

For duplicate handling, define both technical and business identity. A file checksum can recognise an identical file, but it will not necessarily identify the same invoice rescanned or exported differently. Business identifiers and explicit rules for corrections are also needed.

Compare candidates with a scoping worksheet

For each candidate workflow, collect the following evidence and record the corresponding decision:

  • Business value: Collect volume, handling time, rework and delay data. Decide which measurable improvement matters.
  • Input quality: Gather representative files and difficult cases. Define which inputs are included initially.
  • Structural variation: Identify supplier layouts, document types and exceptions. Define the variation the pilot must handle.
  • Reference data: Check available supplier, order or customer records. Establish whether reliable matching information exists.
  • Review ownership: Identify reviewers and their exception-handling capacity. Assign responsibility for uncertain results.
  • Downstream impact: Map record states, permissions and triggered actions. Specify what the system may change.
  • Economics: Estimate implementation and operating costs. Define what result would justify expansion.

Avoid reducing the decision to a score that hides a blocking issue. A promising workflow still needs a responsible owner, usable samples and a workable integration path.

Commission a pilot that supports a decision

The pilot should conclude with evidence: observed performance, remaining exceptions, review effort, operating cost and the work needed to expand.

Possible outcomes include proceeding, narrowing the scope, improving intake or stopping because the economics do not justify further investment. Each is more useful than a demonstration with no agreed success criteria.

Xtreme Systems Solutions can help assess candidate document workflows and define a practical pilot. A focused scoping engagement can produce a sample inventory, workflow map, integration boundaries, acceptance criteria and implementation estimate.

That gives operations and finance leaders a concrete basis for deciding what to automate first—and what to leave for a later phase.

Practical takeaways

  • Select a complete business task, not simply a large document queue.
  • Test representative inputs, including difficult scans and exceptions.
  • Measure correction effort and operating cost alongside extraction quality.
  • Define review responsibility and downstream authority before implementation.
  • Use pilot evidence to decide whether and how to expand.
