Every expense claim checked against policy, not just a sample

What is the business problem, and what does it really cost?

Expense claims look small one at a time. Across a year, across hundreds of employees and thousands of card transactions, they add up. Most finance teams cannot review every line. They rely on spot checks, manager sign-off and a hope that the big problems will surface on their own.

The hidden cost is not only the leakage. It is the time spent by finance analysts re-keying receipts, chasing missing details and debating minor amounts that do not deserve a senior person's attention. Good staff end up doing low-value checking work, and the policy that the board approved is applied unevenly.

• Sampling leaves most claims and card transactions unchecked.
• Duplicate receipts and split purchases are hard to spot by eye.
• Managers approve claims without time to compare them with policy.
• Finance analysts spend hours on routine, compliant items.

What changes for the organisation?

Every claim and card transaction is reviewed against the policy as it arrives. Claude checks each item for the rules that matter: spending limits, approved categories, receipt requirements, travel booking rules, duplicates and unusual patterns. Compliant items move forward without anyone needing to touch them.

Items that break a rule are flagged with a short explanation, such as "hotel rate is above the agreed city limit by a clear margin; receipt attached; no approval recorded". The reviewer sees the reason, the evidence and the suggested next step. Finance stops being a checkpoint that reads everything, and becomes a team that decides the cases that need judgement.

How does Claude connect to your systems?

Claude works with the tools your team already uses. Expense claims and card data are read from your financial system, such as Oracle, so the source of record does not change. Receipts and policy documents can be held in SharePoint or OneDrive, and Excel workbooks can hold reference tables such as city rate limits and approved merchant lists. Where a claim needs follow-up, Claude can prepare a draft message to the employee or approver in Outlook for a person to review and send.

Because Claude reads through Microsoft's secure connection layer, called Microsoft Graph, and the connections your organisation has already approved, it does not need copies of your data scattered across new tools. It works with the access each person already has. A closely related automation is Invoices captured, checked and coded without manual data entry. It is built on Claude for financial services, from Anthropic.

• Oracle remains the system of record for claims and payments.
• Policy documents and receipts stay in SharePoint or OneDrive.
• Excel holds the rate tables and approved lists that Claude checks against.
• Outlook drafts follow-up messages for people to review before sending.

A day in the life: before and after

Before: an expense analyst opens a queue of several hundred claims on Monday morning. She checks a sample, reads receipts by hand, looks up hotel limits in a spreadsheet and sends emails asking for missing details. By Friday she has reviewed a fraction of the claims and feels that the rest are a matter of trust.

After: the same analyst opens a short list. Claude has cleared the compliant claims and flagged twenty items, each with a clear reason and the evidence attached. She reviews the flagged items in under an hour, approves two, sends a question to one manager using a drafted email, and spends the rest of her week on policy questions and process improvements that she never had time for before.

How are governance, security and permissions handled?

Claude only sees what each user is already allowed to see. An employee's claim is visible to that employee, their approver and the finance reviewers who already handle it. No one gains new access to salary, personal or card detail they do not already hold. Every flag shows the rule it was checked against, so the policy remains the single source of truth and can be audited.

Claude never approves or pays a claim on its own. Named people make every consequential decision, and each decision is recorded in the audit trail. The design supports the internal control expectations that finance and audit teams work to, but it does not replace your own controls, and it is not legal or audit advice.

• Access follows each person's existing permissions.
• Every flag cites the policy rule it relates to.
• Named approvers make every payment decision.
• Decisions and reasons are recorded for audit review.

How will you measure success?

Measure what finance cares about. Track the share of claims and card transactions reviewed, not just sampled. Track the number of genuine exceptions caught and how many were resolved before payment. Track the hours returned to the team and how quickly claims move from submission to decision. Finance leaders typically look at policy breach rates over time, as employees learn the rules and the flags become clear.

Set a baseline in the free automation audit so that the results can be compared honestly after the first few months.

• Share of claims and card spend reviewed against policy.
• Number and value of genuine exceptions caught before payment.
• Analyst hours returned to higher-value work.
• Average time from submission to approval decision.

How should you start?

Start with a free automation audit. The audit looks at your current expense policy, the claim volumes, the systems involved and where exceptions are found today. We identify the rules that are easiest to check automatically and the judgement calls that should stay with people. A pilot usually covers one business unit or one type of spend, so the team can see the flags and tune the rules before rolling out more widely.

Many organisations also review how their wider Microsoft 365 setup supports finance work. Our flagship guide to Claude and Microsoft 365 explains how these pieces fit together across the whole organisation.
