Vendor Invoice Audit · 100-Invoice Proof Audit
AP systems process and approve invoices. AllCaps is the audit layer that checks whether the commercial terms on those invoices comply with the governing contract.
Start with your own contracts and invoices. No ERP, CLM, or operational-system integration is required for the standard audit.

The question
Are we paying what we agreed to pay?
CFOs, CPOs, controllers, and AP or procurement leaders who want contract-level assurance beyond ordinary invoice workflow and approval controls.
Beyond workflow automation
An invoice can match a PO and pass every approval while still using the wrong contracted rate, missing a discount, exceeding a cap, or applying an unallowed fee. Those are commercial-term errors, not AP-workflow errors.
AP systems process and approve invoices. AllCaps reads the governing agreement and tests every invoice against the commercial terms your team negotiated.
AP automation processes invoices.AllCaps checks whether the contract was honored.
How it works
The standard Vendor Invoice Audit uses only vendor contracts, amendments or rate cards, and vendor invoices.
Send the contracts, amendments or rate cards, and historical invoices. PDFs and standard exports are fine.
AllCaps maps the governing commercial terms and connects amendments and rate cards to the correct agreement.
AllCaps checks invoice lines and calculations against the contract terms that can be established from those records.
Review evidence-backed findings with the relevant contract and clause support for material issues.
What you get
The Proof Audit demonstrates AllCaps on your records without turning the first step into a consulting engagement or systems project.
A focused set of invoice exceptions established from the supplied contracts, amendments, rate cards, and invoices.
Material findings connect back to the governing contract language so your team can verify the result.
A clear review of what AllCaps found, how each material finding was calculated, and what continuous audit would cover.

After the Proof Audit
If the proof is useful, move the same contract-to-invoice checks into an ongoing software subscription.
AllCaps continuously checks vendor invoices against their governing contracts as invoice volumes expand. Volume-based expansion lets coverage grow with the number of invoices audited.
Subscription pricing
Plans start at $2,000/month.
Standard onboarding is included with subscription plans. Custom integrations, unusual data formats, or significant bespoke normalization may be priced separately.
Send up to three vendor contracts and 100 historical invoices. Review the evidence, then decide whether continuous invoice audit is useful.
