Use caseAccountingExpense reimbursementMonthly closing

Using AI to first-check month-end expense reimbursements against internal policy

Submitted expenses were automatically checked against expense policy, spending limits, and required documents. Over-limit claims, missing receipts, and suspected personal use were sorted with evidence, sharply reducing return work.

"At month-end, hundreds of expense claims arrive at once, and checking each one against policy takes days." We tested how INDX Compliance handles the monthly workload faced by accounting reviewers, using real product screens.

Background

Why monthly expense policy checks are so painful

At one company, the accounting team receives expense claims from employees at the end of every month.internal expense policy, limit tables, invoice requirements, and travel expense policyThey manually judge each claim against those standards. Individual amounts may be small, but a missed issue can create meaningful tax risk.

The hard part is that the standards are spread across multiple documents: entertainment limits in an appendix, invoice requirements in tax rules, and taxi-use reasons in workplace rules.which claim is caught by which policy clauseThe answer depended heavily on reviewer experience. When reviewers changed roles, the same violation could slip through.

Challenges encountered

  • Hundreds of claims arrived at month-end, and checking them against policy took more than 20 hours per month.
  • Missed over-limit claims, receipt defects, or missing invoice numbers could be flagged in a tax audit.
  • Every return triggered email back-and-forth with the applicant, often requiring multiple rounds before finalization.
  • Reviewers had to explain the basis for each return, adding significant communication overhead.
01Trial

Describe the check in plain business language

First, there is no complex setup."Check whether this month's expense claims satisfy the internal policy limits and invoice requirements."We entered that in everyday language, and AI automatically built the review workflow.

Your instruction (plain language is fine)

"Check whether this month's submitted expense claims satisfy the internal expense limits, required documents, and invoice requirements. Sort policy-violating claims with evidence."

AI generated the checklist workflowdraft · 4 steps
  1. 01Import expense policies and related requirements

    Import the internal expense policy, limit tables, invoice requirements, and travel expense policy.

  2. 02Assess each claim against the policy

    Check limits, required documents, and stated reasons claim by claim.

  3. 03Verify evidence and confidence

    Confirm the cited policy clauses and receipt details actually exist.

  4. 04Final human review

    Route only needs-review and non-compliant claims to accounting.

Screen 1From a plain-language instruction, AI generates a 4-step workflow: import policies -> assess each claim -> verify evidence -> final human review. Review the contents and save.

No programming knowledge or complex rule configuration is required. The generated workflow can be reviewed and edited, then reused every month with the same checks.

02Trial

Run it to see pass/fail results with evidence for each claim

After saving and running the workflow, AI checks each claim against internal policy requirements. The results are consolidated on one screen. The key point isevery decision includes the exact policy and clause used as evidence so reviewers do not have to take the AI conclusion on trust and can confirm the source text.

    The meal claim is JPY 8,200 per person, exceeding the limit. It should be returned as a policy violation.

In this test, AI found two issues: entertainment expenses exceeded the JPY 5,000 per-person limit, and an invoice had no registration number and did not meet input tax credit requirements. Both are policy violations that can lead directly to tax risk if missed.

03Trial

Humans review only the needs-review and non-compliant items

The 4 items AI marked as passing have evidence attached and can be checked quickly. Human judgment is reserved forthe 2 needs-review items and 2 non-compliant items, 4 items in total. The reviewer returned the non-compliant claims to the applicant, reran the corrected resubmissions, and finally approved and locked the results.

Final review (human confirmed)

Non-compliantEntertainment expenses must stay within the per-person limit

The meal claim is JPY 8,200 per person, exceeding the JPY 5,000 policy limit. The applicant was asked to resubmit the receipt and correct the amount.

Humans review only the 4 needs-review and non-compliant items.The 4 passing items can move through with evidence attached, so reviewers can focus on judgment.

Screen 3Left: humans review only items that need action. Right: every action, from AI decision to human approval or return, is automatically preserved in a tamper-proof log.

Every action and decision is recorded in a tamper-proof audit log. Teams can later trace who decided what, when, and based on which evidence, and reuse that record for tax audits and internal audits.

Outcome

Result: monthly reimbursement checks dropped from 20 hours to 3 hours

The first-pass review workload, previously over 20 hours per month, was completed from check preparation through final confirmation in3 hours. Most importantly, over-limit claims and missing invoice numbers were automatically detected before returns went back to applicants.

Key points from this case

  • Configure the check with a plain-language instruction. No specialist knowledge or programming is required.
  • Every pass/fail decision includes the original policy or invoice requirement as evidence, so people can verify the AI work.
  • Humans review only needs-review and non-compliant items, allowing them to focus on judgment and reduce missed issues.
  • Actions and decisions remain in a tamper-proof log that can be used directly for tax audits and internal audits.
Summary

Expenses, contracts, applications: rule checks follow the same pattern

This example focused on expense reimbursement, but INDX Compliance works the same way across use cases.Provide the standard documents, such as internal policies, laws, or invoice requirements, along with the documents to check, such as claims and receipts, and compare them with evidence attached. The same workflow applies to contract reviews, approval checks, ISO audit preparation, and any operation that requires checking documents against rules.

Try it in your workflow,starting with one document.

Bring a policy, contract, or application document, and we will demo the actual judgment screen. Closed-network and on-premise deployments are supported.
