Audit process

How a Think Online engagement moves from claim extract to findings memo for travel expense applications.

A process shaped by claim files

Financial audit of travel expense applications is document work. The sequence below is what we follow on most engagements, adjusted for sample size and whether original paper stays on your premises.

1. Engagement letter and intake

We confirm the period, entities, and cost centres in scope. You provide the travel policy, the application extract, and any known risk notes (for example, cash advances or multi-city sales tours). A deposit may be required for larger engagements — see Fees and Refunds.

2. Population understanding

Before sampling, we scan the extract for obvious clusters: destinations, average claim size by department, weekend travel, and repeat applicants. This step shapes the sample; it is not yet a full test of each line.

3. Sample design

Materiality and risk drive selection. High-value lodging, overseas per-diems, and applications with prior exceptions receive heavier weight. Pure random selection is used only for a portion of the sample so routine domestic trips are not ignored.

4. Evidence testing

Each sampled travel expense application is matched to receipts, itineraries, and approvals. We note missing boarding evidence, date mismatches, amounts above caps, duplicated routes, and approvals that lack a dated signature or system stamp.

5. Interim discussion

Material findings are shared with your nominated finance contact before the final memo. This is the moment to supply late evidence or correct misfiled attachments — not to renegotiate policy after the fact.

6. Findings memo

The memo states exception counts and rates by category, lists claim references, and offers remediation notes (policy wording, approval checkpoints, or traveller guidance). Appendices can include working-paper summaries when your internal audit team requests them.
