How SGG checks what happens after signing.
Establish the governing record. Test current billing against it. Document what the evidence supports—and what remains unresolved.
The complete review framework
Define exactly what is being reviewed
Select the recurring service category, review period, vendor relationships, locations and available billing population. The final report states those boundaries so “reviewed” never implies more than was actually tested.
Start with what the client already has
An AP export, CSV, invoice folder or existing contract file is enough to begin. SGG organizes the starting population, identifies duplicates and gaps, and returns a targeted request for only the additional records needed.
Establish the governing record
Executed agreements, proposals, amendments, purchase orders, rate notices, approvals and renewals are placed in sequence. Merely possessing a document is different from determining that it governs the period being reviewed.
Build the source-linked ledger and run the tests
Billed rates, descriptions, dates, recurring and non-recurring charges, and documented changes are normalized so unlike records can be compared. Each tested item remains traceable to the invoice and governing evidence used. Where the accounting data contains usable transaction identifiers, SGG can also reconcile invoice-source records against ledger postings as an additional verification control.
Investigate before classifying
An apparent mismatch may be an exception, an authorized change, a timing issue or a limitation in the available record. SGG records the evidence finding as Passed, Exception or Could Not Verify. Human Review Required is a separate flag that can accompany a finding when judgment is needed. Passed means the stated test aligns with the available governing record; Exception means an evidenced departure; Could Not Verify means necessary evidence is missing. Each result applies to the stated test and period. Client follow-up is recorded separately.
Deliver the result and preserve continuity
The report separates tested facts, open questions, decisions and recommendations, with an executive view and supporting evidence. The governing record and unresolved items carry forward so the next cycle does not begin from zero. A later review covers billing issued since the last one, any terms or authorizations that changed in the interval, and the current status of items left unresolved. The report delivered now is complete on its own terms.
What SGG does—and doesn’t do
SGG owns the defined review. Your team retains the vendor relationship, operating authority and decisions about what to address.
SGG handles
- Defining the review scope and population
- Establishing the governing record from the available agreements, amendments and approvals
- Testing billing against that record
- Documenting findings, evidence limits and open questions
- Preserving unresolved items for later review
Your team retains
- Vendor communications and response chasing
- Procurement, legal review and negotiation
- Operational and service-level judgments
- Decisions about whether and how to act
- Day-to-day vendor management
The client should not need to do a second job to receive the review.
