01 / Define the boundary
Set a clear expense-review boundary.
Begin with one observable slice of work rather than a broad goal to “automate expenses.” Identify where receipts arrive, which records are compared, who can resolve questions, and what the final review must leave behind. A narrow boundary makes it easier to see where assistance ends and accountability begins.
- Which receipts are in scope: employee expenses, company-card transactions, reimbursements, travel, or another defined group?
- What starts review, who owns the queue, and what counts as a complete review?
- Which policy, budget, accounting, tax, or approval records are used for comparison?
- Which person can resolve an uncertain vendor, amount, category, or business-purpose question?
Defining a workflow is not evidence that AI assistance is appropriate, accurate, available, compliant, or beneficial for it.
02 / Walk the process
Follow this sample receipt-review workflow.
Adapt the stages to the organization’s actual intake channels, policies, approvals, and recordkeeping. Each stage includes a human checkpoint before the next consequential step.
Receive and prepare the receipt
Collect the receipt through the organization’s established channel, associate it with the relevant expense or card transaction, and check that the image or document is readable and complete enough to review.
Human checkpoint
A person confirms that the receipt belongs to the intended expense, is not an obvious duplicate, and may be used for this review before any extracted information is relied on.
Extract and organize information
AI may assist with a draft of fields such as vendor, date, total, currency, tax, line items, payment method, and a proposed category. Keep the original receipt beside the proposed fields and label missing or uncertain values.
Human checkpoint
A reviewer checks each consequential field against the receipt, corrects omissions or misreads, and marks uncertainty rather than allowing a plausible-looking field to become fact.
Compare with policy and source records
Compare the reviewed receipt details with the applicable expense policy, transaction record, approval context, budget or project information, and any required business-purpose evidence.
Human checkpoint
The responsible reviewer decides whether the evidence supports the proposed category or treatment. AI output can point to a possible mismatch, but it does not interpret policy, approve an expense, or replace qualified accounting or tax review.
Route exceptions for resolution
Classify open questions such as a missing receipt, unclear business purpose, duplicate, unusual vendor, amount mismatch, policy exception, sensitive purchase, or suspected fraud, then send each to the established owner.
Human checkpoint
A person reviews the evidence and chooses the route: request clarification, send to a manager or finance reviewer, hold the item, or escalate a sensitive case. Do not auto-reject, reimburse, or accuse someone from an unverified flag.
Record the final outcome
After the review and any escalation, record the decision, corrections, reviewer, evidence checked, unresolved questions, and follow-up in the organization’s authoritative expense or accounting record.
Human checkpoint
An authorized person gives the final approval for the record change or payment-related step. The reviewer verifies the saved result against the source receipt and preserves the original rather than silently overwriting it.
03 / Bound the assistance
Choose assistance that stays inspectable.
Consider AI for information-friction that a reviewer can inspect and correct. Keep the source receipt, the proposed output, and the reviewer’s decision together so the process does not turn an unverified suggestion into a financial record.
- Draft field extraction
- Suggest receipt fields for a person to compare with the original document, including a visible indication of missing or uncertain information.
- Organize a review queue
- Group items by missing information, possible duplicate, policy question, or another documented review category for human triage.
- Prepare neutral notes
- Draft a source-linked summary of what was checked, what differs, and what question remains without deciding the outcome.
- Highlight possible mismatches
- Point out differences between reviewed receipt fields and supplied records for a reviewer to inspect, not a rule to apply automatically.
Assistance is not approval, reimbursement authorization, accounting or tax advice, fraud determination, or permission to change a source record.
04 / Protect the data
Treat receipts as financial and personal data.
A receipt can expose names, locations, habits, payment details, employee information, or sensitive purchases. Apply the organization’s privacy and security responsibilities at the point of intake and again before any assistive processing.
- Minimize the data
- Send or expose only the receipt fields and supporting context needed for the defined review. Avoid unrelated purchases, full card numbers, authentication data, or personal details that are not necessary.
- Control access
- Limit receipt images, extracted fields, prompts, outputs, and review history to people with a legitimate role. Check that access follows the organization’s existing permissions and separation of duties.
- Set retention and deletion rules
- Decide how long source receipts, intermediate outputs, logs, and rejected drafts should remain, who can delete them, and which accounting or legal retention duties apply before deletion.
- Redact sensitive fields
- Consider masking card numbers, addresses, medical or employee information, loyalty identifiers, and other sensitive details before using a receipt in an assistive step when those details are not needed.
- Verify data use
- Before using a provider or model, read its current terms, privacy information, retention settings, access model, and any option affecting whether submitted data is used for training or service improvement. Do not assume a setting exists.
- Escalate uncertainty
- Pause and use the organization’s privacy, security, finance, legal, or safeguarding route for uncertain, sensitive, disputed, or high-consequence cases.
Provider or model behavior can change. Verify current data-use terms and settings for the service under consideration; do not infer privacy, retention, security, or confidentiality from a marketing label.
05 / Stay accountable
Keep consequential decisions and records human-reviewed.
Human review is a control only when the reviewer has the context, time, authority, and source material to challenge the output. Do not let a draft silently alter a receipt, expense category, approval status, reimbursement, accounting entry, vendor record, or payment instruction.
- Require a named reviewer to accept, correct, reject, or escalate the proposed result.
- Preserve the original receipt and show corrections rather than hiding the history of an output.
- Pause for unusual, disputed, sensitive, potentially fraudulent, or out-of-authority cases.
- Record the evidence checked, reviewer, decision, escalation, and unresolved uncertainty in the established system of record.
06 / Keep the scope honest
Use a practical checklist before relying on a workflow.
Start with a small, read-only or draft-only review if the organization decides to test assistance. Observe corrections, missed or unnecessary flags, privacy concerns, review effort, and escalation quality. Those observations are local evidence—not a guarantee that another workflow, provider, model, or integration will produce the same result.
Before you begin
- Is the receipt and its source record identifiable, readable, and linked to the right expense?
- Which fields may be drafted or organized, and which fields must a person verify before use?
- What policy or record is authoritative when the receipt, transaction, and proposed output disagree?
- Which exception types have a named owner, response path, and stop condition?
- What data is minimized, redacted, access-controlled, retained, and deleted at each step?
- Who authorizes the final decision or source-record change, and how is the review evidence preserved?
