Protect your company’s reputation and revenue from the first time you engage with a supplier and throughout the supplier lifecycle.
How does a procure-to-pay recovery audit, revealing and recovering duplicate payments, statement credits and overpayments outside of ERP controls help The Mosaic Company protect profit? Laureen Stephens, AP Manager for EBS/North America Shared Services tells us how procure-to-pay errors occur in the normal course of running a $19B mineral production business and why she is committed to recovering overpayments before they are lost forever. Want to hear Laureen’s story? Listen to the recorded webinar.
Laureen: Yes, we had five people who focused on reconciling supplier statements. We used a combination of staff and contractors. While it was a valuable process, it was time-consuming, not a primary focus for the AP organization, and not the specific skillset of the team. We realized that the skill and time of some of these team members could be directed to more value-added AP and P2P activities. So when we changed to a shared services model, we dissolved the statement reconciliation team and eliminated the need for contractors to support the statement reconciliation process.

Pete: For vendor credits, I recommend that internal teams focus on statement credits in the 90 days after the payment. It is a manageable time frame for the AP team to resolve open credits, while also making sure that they are doing the priority work: paying vendors according to terms, meeting key performance indicators (KPIs) and managing communications with suppliers. But once that 90 days is over, apexanalytix can come in and start our process, one that has been refined for 35 years, to find duplicate payments, statement credits and other overpayments that haven’t been identified or recovered.
Laureen: We did an audit that included disbursements for the US, Canada and LATAM. Our ERP system is SAP. The apexanalytix audit team reviewed 2.5M invoices, expenditures of $19.5B, credits aged over 90 days, for 2,318 suppliers. There were 293 recoveries totaling $1.8 million that went right back to the bottom line. The scope included duplicates and statement credits but we are looking at other audit areas in the future.
Pete: A basic review includes three areas:
Four other areas of audit that we can perform are:
An uncashed check review, in which we research uncashed checks to identify those that don’t require escheatment to U.S. government authorities.
An unclaimed property review, that involved review of states’ and other local jursidictions’ databased for client funds escheated by other parties and owed to our client.
Contract and pricing compliance reviews, where we compare contract terms and related transactions to identify non-compliance and recover associated overpayments.
And a sales and use tax review that looks at sales transactions and use tax returns to identify overpayment of taxes according to taxability rules for products and services.
The cool thing is, once we have a relationship with a client for an AP audit, and their transactional data it makes it easy to move into other areas of value. For each of these, we have distinct practice under the leadership of professional experts in each audit area.
Laureen: There are a few reasons this makes sense for us:
Laureen: apexanalytix’s audit team works directly with suppliers. You may be surprised at how many times something is on the supplier’s books that isn’t on our books. It could be because of a pricing versus invoice error, a return, overpayments related to a material PO or a service PO, or a unit of measure error – a tonnage issue that leads to a unit of measure overpayment, for example.
Pete: We call our method “People Empowered With Technology.” Think about this: Laureen has 2,318 suppliers. That’s 2,318 back-and-forth communications to ask for a statement, get a current statement, identify if credits exist, verify the credit, get the supplier agreement, and post the recovered amount. We reach out to them through a process that combines calling, emailing, and most importantly, a workflow that takes care of follow up. We also use intelligence to identify credits on statements. I challenge any other recovery audit company to be able to manage communications with suppliers more efficiently. It’s a process that the supplier appreciates and gets the client money faster. Sometimes people forget that an overpayment is a financial error on the books of the supplier. They want to clear it up as timely as possible. Nothing is worse for a supplier than to have to issue a credit months after the transaction. And nothing is worse for the client than money that should have been profit but is gone forever because a supplier can’t be reached to confirm the recovery.
Four things are unique assets apexanalytix has when we perform an AP recovery audit.
Laureen: I have a recommendation for other companies on this topic. Give apexanalytix what they need so they can work as independently as possible. They have an automated data extraction process for SAP, so that’s easy. They get the transactional data they need for the duplicate review right at the start. And once we decide on the scope – the suppliers to be included in the audit – they get to work right away with the outreach based on the supplier list we provide. We go a step further and gave apexanalytix a secured laptop with read-only access into our SAP system so they can research the claims on their own. This way they can do nearly 100% of the work themselves, and even get the authorization from the supplier to make the final deduction.
One of the best parts of the audit is the apexportal auditview application. Every single claim in progress, updated in real time, is there for me to see. I use this to watch the progress of the audit. And when apexanalytix has a question or is having any problem resolving an issue, we are looking at the same information together to work on the solution.

Laureen: If you have had any changes in our AP process or systems, like the one we are going through now, don’t wait to do a recovery audit. An audit on your past AP transactional data will give you not only the recoveries, but you’ll have an AP benchmark of your payment process. You have the potential to uncover possible control weaknesses in procure-to-pay, in areas like returns, receiving, procedural errors in AP, and much more. And then, once you’ve gone through the upgrade, consolidation, or whatever change is happening in your world, you should do another recovery audit. We are looking forward to comparing the audit results to see what we need to correct and improve upon, within AP, and with our partners in procurement. And of course, we look forward to the return of the recovered dollars.
Pete: Just an invitation to any company out there who is disbursing billions of dollars to give apexanalytix a try. I’ve been here for 24 years, and the progress I’ve seen in the industry and in our approach to audit has kept me excited about how we can help AP leaders like Laureen make a real difference for their companies.
| Topic | Key Point |
|---|---|
| What it is | An AP recovery audit is a review of accounts payable transactions designed to identify and recover duplicate payments, supplier credits, tax overpayments, and other financial leakages that fall outside ERP controls |
| Why it matters | Overpayments occur even in well-managed organizations due to process complexity, system changes, supplier errors, and human mistakes. Recovery audits help organizations recover lost profit and strengthen financial controls |
| Core audit areas | Standard reviews typically include duplicate payments, supplier statement credits, and debit balances, with additional opportunities in uncashed checks, unclaimed property, contract compliance, and sales and use tax recovery |
| How it works | Audit teams analyze transactional data, review supplier records, identify discrepancies, validate claims, and work directly with suppliers to recover funds owed to the organization |
| Recovery results | Organizations can uncover significant value through recovery audits. In The Mosaic Company’s audit, 293 recoveries totaling $1.8 million were identified across 2.5 million invoices and $19.5 billion in spend |
| Best practice | Allow specialized recovery audit teams to operate independently with access to the required data while internal AP teams remain focused on supplier payments, KPIs, and day-to-day operations |
| Bottom line | Recovery audits help organizations protect profit, recover lost funds, identify process weaknesses, and improve procure-to-pay controls without disrupting core AP operations |
apexanalytix reviewed 2.5 million invoices and $19.5 billion in spend across 2,318 suppliers, identifying 293 recoveries totaling $1.8 million in overpayments and credits.
Overpayments accumulate through normal business activity: pricing-versus-invoice mismatches, returns, and unit-of-measure errors. Many only appear on the supplier’s books, rather than the buyer’s.
Internal AP teams are best positioned to resolve credits within the first 90 days after payment. Specialized recovery audit providers then take over to find older, more complex overpayments that internal teams do not have the time or supplier access to pursue.
Supplier statement reviews tend to be the largest source, since they surface credits, pricing discrepancies, and other balances sitting on a supplier’s books that never appeared in the buyer’s own records.
