View 1 of 4: What was agreed?

Processing an invoice is not the same as validating it.

TriangleAudit goes beyond traditional AP automation by verifying invoice charges against what was agreed, what was delivered, and what was ultimately invoiced. The result is greater payment accuracy, stronger financial control, and valuable charge-level data that can be transformed into actionable insights.

What is a Triangle Audit?

A Triangle Audit validates three fundamental elements of every invoice:

1. What was agreed — contract, PO, quotation, rate card, discount, or commercial terms.

2. What was delivered — product, service, shipment, quantity, weight, supporting documentation, or project milestone.

3. What was invoiced — every rate, fee, surcharge, tax, discount, and line-item charge.

Then TriangleAudit determines:

Agreed → Delivered → Invoiced

Do they match?

This three-point validation helps ensure organizations pay the right amount, for the right product or service, under the right terms.

Validate Every Charge

TriangleAudit combines automation, digitized commercial terms, configurable audit rules, and industry expertise to validate invoices at the line-item level.

For freight invoices, supporting shipment documents can be verified while our rate engine digitizes contracts and rate tables to validate invoiced rates automatically.

Accessorial and service charges can be checked for validity, contracted pricing, and applicable discounts. Invoice and PO validation can compare pricing, quantities, services, and other agreed terms.

For project-based AP, invoices can also be validated against budgets, quotations, milestones, purchase orders, contracts, and approved changes before entering the appropriate approval workflow.

Every Triangle Audit Creates Data

The value of a Triangle Audit does not end when an invoice is validated.

Every audit produces structured, charge-level data that provides a deeper understanding of what an organization is actually spending.

Instead of seeing only the total invoice value, TriangleAudit can provide detailed visibility into individual cost components such as:

• Base charges
• Service charges
• Accessorials and surcharges
• Taxes and duties
• Discounts and credits
• Project or vendor costs
• Variances and exceptions

This transforms invoices from payment documents into a valuable source of spend intelligence.

From Cost Breakdown to Actionable Insights

TriangleAudit analytics can compare:

Agreed Cost vs. Invoiced Cost

and

Forecast Cost vs. Actual Cost

Organizations can identify what caused a variance, quantify its financial impact, and analyze patterns across suppliers, projects, locations, business units, expense categories, and individual charge types.

A recurring incorrect rate becomes a supplier performance insight.

Increasing surcharges become an operational cost insight.

Missed discounts become a contract compliance opportunity.

Actual costs consistently exceeding forecasts become a planning and procurement insight.

Turn Audit Data into Better Decisions

TriangleAudit dashboards and reporting provide visibility into invoice status, spend, cost breakdowns, exceptions, supplier performance, contract compliance, overpayments, and savings opportunities.

This creates a continuous value cycle:

Audit → Data → Insight → Action → Savings

The more invoices processed through TriangleAudit, the stronger the organization's cost intelligence becomes—supporting better forecasting, budgeting, procurement, supplier negotiations, and cost optimization.

More Than an Invoice Audit

TriangleAudit connects invoice accuracy with spend intelligence through one end-to-end process:

Receive → Validate → Verify → Approve → Analyze → Optimize

Know what was agreed. Verify what was delivered. Audit what was invoiced. Understand every charge. Turn the data into insight. Use the insight to reduce costs.

Agreed → Delivered → Invoiced

That is a Triangle Audit.
