Meet Illumis

We help businesses increase profitability, mitigate potential risks, and enhance internal processes throughout all facets of the supplier relationship.

What We Do

Auditing: Powered By People

It happens to everyone: unpaid invoices slip through the cracks, discounts and allowances are not applied, items with errors age out of visibility, duplicate invoices are pushed through…in short, no one is perfect but 99.9% is pretty darn close.


Recovery auditing helps you find and correct those pieces that keep your business from running at maximum efficiency. Many recovery audit contractors rely on mass mailing methods and artificial intelligence to request statements and find inconsistencies, but we take a human approach. While duplicate filings are easy to find with an automated program, they only account for 20-30% of available recoveries. At Illumis, our team works in conjunction with our software solutions to locate the other 70% of recovery potential.


Our analysts dig deeper, go further, uncover more, and most importantly, they have live discussions with your suppliers. They understand the nuances of a diverse supplier base, from business practices to language differences, and they deliver exceptional service for every client, every day.

BI Solutions: Insight. Visualize. Decide.

A SaaS solution that combines analytics and data visualization to help you easily find answers and take action on opportunities hidden in your data. IBIS is a suite of applications that work together to solve problems.

Vendor Scrub

We identify relationships between vendors so you can clean, validate and standardize your vendor master. This report scores each vendor group allowing you to direct your internal resources where the greatest corporate impact can be realized.



Our exclusive IQ identifies “non-matching” duplicates allowing you to see and uncover more than traditional match-based tests. By finding errors early, they can not only be prevented but others can be identified and recovered before they age.



You will see a meaningful display and analysis of payment terms offered by your vendors. You can then answer: Am I using the best terms available? Am I taking all the discounts I qualify for? Ensuring that you use the most profitable. 



We execute a range of tests across suppliers, employees, and payable data to identify suspect activity. Each vendor is scored based on thresholds and points assigned. You can visualize risk to ensure your profit is protected now and in the future.



Your vendor master is compared to government watchlists and provides a list of potential matches. This gives your organization continuous protection and compliance.  



The intuitive system enables you to easily select, extract and view data across divisions, locations, ERP systems, and more, effectively answering not only “who” and “what,” but “why” and “what if.” Knowledge is power. Power can impact. We intend to arm you with the information you need to make impactful decisions. 

Advisory: Verify. Confirm. Inform.

An Illumis Advisory audit assures that your vendor relationships are operating as efficiently as possible, while identifying leakage and highlighting potential risk areas.


Cost Savings

Verifying bills received from suppliers can help to improve cash flow by identifying overbillings and implementing best practices to address them going forward.


Improved trust and business relations 

Performing contract compliance audits and working with other companies to fix any issues – big or small – can establish trust with partners and build long-term relationships.


Find areas of non-compliance/Billing accuracy

Non-compliance comes in big and small forms. A deep-dive is often required to confirm billing inaccuracies. Inaccurate billing is rarely intentional. Instead, it is small mistakes that can add up. An audit could take a deep dive into confirming invoice amounts and determining if you have overpaid.


A better understanding of internal controls

How do you ensure a contract is being upheld? Are there steps in place to identify and rectify non-compliance, especially in its subtle forms? The findings from an Advisory audit can help to shed light on internal blind spots and allow for process improvements.

Improving How You Manage Contracts

There’s always room to improve how you manage contracts. Audits can offer data-driven guidance on upgrading internal processes and controls.


  • Cost Recovery — Review price changes, discount eligibility, per-unit prices, rebate calculations, and risk areas to maximize recoveries and savings
  • Contract Compliance — Analyze supplier contracts for comprehensive audit clauses, price change protection, reasonable insurance guidelines, clear document hierarchy, and accurate fee calculation methods
  • Infrastructure Review — Examine electric power, water, natural gas, and sewer accounts to ensure you’re receiving the most advantageous rate structure available and all applicable tax exemptions
  • Process & Procedure Review — Ensure that all documents are formatted correctly, are warehoused in the appropriate locations in the correct systems, and are being adequately reviewed by your team
