Your Top Questions Answered

How long does the audit take?

Our audits typically take 90–120 days from kickoff to final report. This includes time for secure data transfer, automated analysis using our IQ platform, expert validation by our audit team, and delivery of verified recovery opportunities.

What systems are supported?

We integrate seamlessly with all major ERP and AP platforms, including SAP, Oracle, Microsoft Dynamics, PeopleSoft, Workday, JD Edwards, NetSuite, and others. If you have a custom or hybrid system, our team can adapt our process to fit your environment.

Is this success-based pricing?

Yes. You only pay if we recover funds. Our fee is a percentage of the validated recoveries we identify. There are no upfront costs or hidden fees, and our rigorous validation process ensures accuracy and protects your vendor relationships.

Will this burden our AP team?

No — the lift for your internal team is minimal. We handle the data extraction and analysis, and our audit specialists manage the entire review process. Your AP staff may only need to provide access to data and occasionally answer clarifying questions, keeping their day-to-day work uninterrupted.
