Sampling versus full review when claim volume spikes

When claim counts jump after a conference season or a new subsidiary onboarding, finance desks face a choice: test everything or sample with intent.

When full review still makes sense

Full review fits small populations — for example fewer than two hundred claims in the window — or situations where prior periods showed concentrated issues in one cost center. It also suits cash-heavy categories where a single missed receipt can be material.

When stratified sampling is enough

Larger populations benefit from strata by claim type, amount band, or business unit. Entertainment and international travel usually deserve heavier sampling than office supplies. Document the method before testing starts so board readers understand why certain claims were not opened.

What sampling cannot replace

Sampling will not surface every duplicate or every policy stretch. Pair it with targeted scans for identical amounts on the same day and for vendors that appear unusually often. Those scans are quick and catch patterns random samples miss.

Closing the loop

Whatever method you choose, leave time for management responses. Findings without owner comments look unfinished in an internal audit file.
