Auditing and vendor governance can examine the same evidence. A capable invoice or contract audit may test agreed rates, amendments, escalation clauses and approvals. The useful question is what is covered, how often it is reviewed, and who is responsible for delivering a documented result.
What invoice auditing asks
- Is the invoice mathematically correct?
- Was it approved?
- Was it paid once?
- Was it coded correctly?
- Does billing comply with contractual pricing and authorized changes within the audit scope?
What vendor governance asks
- Does the current relationship still match the agreement?
- How did rates and scope change over time?
- Can approvals and amendments be reconstructed?
- Are comparable locations governed consistently?
- What did the review establish, and what remains unresolved for the client?
Same test, a defined responsibility
An invoice for $463.50 reflects a 3% increase from $450. Both an audit and an SGG review can test whether that increase was permitted, effective in the billed period and supported by the record. SGG’s proposition is a defined review population, an agreed review cadence and a documented finding—not exclusive ownership of the test.
Why both matter
Existing audit and accounts-payable work should inform the scope, so the client understands any overlap. SGG accepts responsibility for delivering the agreed recurring-vendor review, identifying its evidence and limits, and reporting unresolved items within later review scopes. The client retains vendor contact, corrective action and operating decisions.
Frequently asked questions
Does SGG replace an audit?
No. It complements financial and operational controls by examining the ongoing vendor relationship across documents and time.
Can an invoice be correct but still raise a governance issue?
Yes. The amount may be accurate while the rate change, service description or approval trail remains unclear.
See the relationship, not just the invoice.
SGG reviews contracts, invoices, amendments and recurring service patterns across the organization.
