PBC list
A PBC list — “provided by client” — is the auditor’s itemized request for the documents and evidence your team must hand over: policies, access reviews, change tickets, logs, HR records. It arrives at the start of fieldwork and effectively defines the workload of the audit.
Short for “provided by client” — the auditor’s itemized list of documents and evidence the audited organization must deliver before and during audit fieldwork.

Glossary · PBC ListWhat lands on it
A typical SOC 2 PBC list runs dozens to a few hundred line items, each tied to a control the auditor plans to test: the access-review records with approvals, the offboarding tickets for a sample of departed employees, the vulnerability-scan reports, the signed policy acknowledgments. Because most items are the output of year-round evidence collection, the list is less a task than a retrieval exercise — for teams whose evidence exists. For everyone else, it is where the audit window comes due, since many artifacts are timestamped and cannot be recreated after the fact.
What first-timers misjudge
Three things surprise teams on their first audit. Volume: the list keeps growing, because auditor follow-ups spawn new items as testing proceeds. Deadlines: items are due in days, not weeks, and late delivery stretches fieldwork. Ambiguity: requests are written in auditor shorthand — “population of changes for the period” — and guessing at the meaning wastes a round trip. The teams that clear lists fastest ask clarifying questions on day one and over-deliver context on the first pass.
Working it like an operator
Mature teams treat the PBC list as a project: every line item triaged, assigned, and tracked to delivery, with ambiguous requests clarified early instead of guessed at. Slow or partial responses invite deeper sampling; fast, complete ones shorten the engagement. We keep a full breakdown of how the list is structured, who should own each category, and where teams lose the most time in our auditor PBC list guide.
