GENERAL VENDOR INVOICE REVIEW
Vendor invoice reviews,
backed by evidence.
Harbor reviews vendor invoices against your agreements and supporting records. A human reviewer checks potential billing discrepancies, explains the evidence, and identifies what needs clarification.

FOR THE PEOPLE RESPONSIBLE FOR VENDOR SPEND
Clarity for finance, procurement, and operations teams.
When a vendor charge does not match your expectations, Harbor helps you trace it to the applicable terms and supporting records.
WHAT WE REVIEW
Charges in context.
Contracted rates, quantities, recurring charges, duplicate billing, and approved extra work—where the available records support the comparison.
Usage, quantities, duplicate status, and other facts require supporting evidence. An invoice alone may not be enough.
01 / HOW IT WORKS
A focused review.
An explained assessment.
Document submission requires a separately authorized, approved intake process. Arrange the scope and authorized intake method with Harbor before sharing documents.
- 01
Provide the invoice and relevant records.
Define the scope and gather the applicable agreements, amendments, approvals, and supporting records.
- 02
Harbor compares charges with the applicable terms.
Differences and missing support are identified for review, with calculations where the evidence supports them.
- 03
A human reviewer assesses the findings.
The reviewer checks what applies, what is supported, and what needs clarification.
- 04
You receive an explanation and a next action.
A findings report distinguishes supported discrepancies, missing evidence, and unresolved questions.
02 / A FICTIONAL EXAMPLE
Same invoice.
Different evidence.
$1,200 billed. A $1,000 contracted base. See how an approved $200 extra—or missing records—changes the assessment.
One invoice. Different supporting records.
Switch fictional evidence with the buttons or arrow keys. This does not approve a finding, extra work, or a customer decision.

The billed amount stays the same in every scenario. The applicable evidence changes what can be concluded.
Quantities and usage need their own evidence. The invoice alone does not establish what was delivered, agreed, or authorized.
A difference worth checking.
Agreement § 2.1 · page 2
Equipment rental is charged at $100 per unit-day. Separately approved extra work is additional to this rate. Applicable amendments must be considered.

Human review required · not verified
Potential supported discrepancy · Fictional illustration
The fictional records support a $1,000 base amount against $1,200 billed: a $200 potential difference, conditional on no applicable amendment or approved extra.
$1,200 billed − (10 × $100 contracted + $0 approved extra) = $200 potential difference
Next action: A human reviewer must confirm the terms, quantity record, amendments, and extra-work approvals before presenting a finding.
Fictional, browser-only demonstration. No review completes and no approval, recovery, refund, credit, saving, or customer decision is recorded.
A difference is not automatically an invalid charge. Amendments, approved extras, missing records, and other applicable terms can change the assessment.
03 / HUMAN REVIEW
Technology assists.
People make the assessment.
Software can help organize records and surface differences. Human reviewers check the applicable terms, amendments, approved extras, and supporting evidence before a finding is presented.
The comparison workflow and human approval are separate. A flag is a question to investigate, not a decision to recover money.
04 / THE FINDINGS
Clear about the evidence.
Honest about the limits.
The outcome of a review should explain what the records support—and what they do not.
- 01Supported discrepancy
- The reviewed records support a specific difference.
- 02Clarification needed
- A material question must be resolved.
- 03Insufficient evidence to assess
- The available records do not support a reliable conclusion.
THE DELIVERABLE
A findings report.
A findings report showing the reviewed charges, relevant supporting records, calculations where supported, limitations, and recommended next actions.
The report distinguishes an evidence-supported difference from an unresolved question. It does not guarantee a credit or refund.
05 / PREPARE THE RECORDS
A bounded scope.
The relevant records.
Start with a defined set of vendor invoices and their applicable terms. Include changes and approvals that could explain a difference.
The initial conversation defines the review scope and the records needed. Documents are shared only through a separately authorized intake process.
Bring the whole picture.
- 01The invoice
Charged lines, dates, quantities, currency, and totals.
- 02The applicable terms
Agreements, rate sheets, purchase orders, and amendments.
- 03The support for the charge
Approved extra work, usage or delivery records, and evidence needed to establish recurring or duplicate charges.

CLEAR EXPECTATIONS
Before the review.
A few useful distinctions.
Which vendor invoices does Harbor review?
Harbor’s review model covers general vendor invoices against agreements and supporting records. The applicable records and scope determine what can be assessed.
Does a potential difference mean an invalid charge?
No. An amendment, approved extra, different service period, or missing evidence may explain it. A human reviewer must check the applicable records before presenting a finding. No savings or recovery is guaranteed.
Where does AI fit?
Software helps organize records and compare charges. Human reviewers remain accountable for the assessment. Live AI document processing is not currently available; this fictional example uses fixed records.
Can Harbor draft, approve, or export a dispute?
Versioned dispute drafting, approval, and export are not currently available. They are separate from the review and findings-report workflow. A customer’s acknowledgment records a response to a report; it does not authorize or send a dispute or vendor communication.
Can I submit documents or contact Harbor here?
Use “Discuss an invoice review” to start an email conversation with Harbor. Do not email invoices or confidential records. Document intake requires a separately authorized process; this website and the fictional example accept no uploads. There is no submission form.
