See how ARDEM helped a national environmental transportation company process 500 to 600 invoices weekly, maintain same-day turnaround, and manage pending items across two business entities.

Cross-trained coverage
A national environmental transportation company needed a more reliable billing lane for customer invoices tied to purchase orders, amount verification, customer-specific dispatch requirements, two business entities, and recurring pending-item follow-up.
The Challenge
More than 2,000 monthly invoices moved through weekly billing cycles, but missing purchase orders, amount mismatches, inconsistent subcontractor formats, and customer-specific requirements slowed finalization and dispatch.
Recurring AR employee turnover and separate entity coverage created continuity risk. Leadership needed stronger ownership of invoices that were ready, invoices that were blocked, and the follow-up required to move pending items forward.
The ARDEM Solution
ARDEM created a managed AR billing workflow around daily queue prioritization, PO and amount verification, exception follow-up, invoice dispatch by email or print, SharePoint and email visibility, weekly reporting, monthly summaries, and cross-trained support across both entities.
The model supported 500 to 600 invoices per week, maintained same-day invoice turnaround, and processed more than 99% of invoices without errors.

Why ARDEM
The Results
ARDEM maintained same-day turnaround across more than 2,000 monthly AR invoices while processing 500 to 600 invoices per week across two business entities. More than 99% of invoices were processed without errors, and the managed workflow gave the client clearer ownership of ready and pending invoices, stronger PO and amount verification, customer-ready dispatch, cross-trained continuity, and recurring visibility into volumes and blockers.

The Invoice Volume Was Only the Visible Problem
The Larger Risk Was Losing Billing Continuity and Pending-Item Visibility
The client did not only need faster invoice preparation. Every invoice had to be matched to the correct PO, checked for amount accuracy, completed according to customer requirements, and dispatched through the correct channel.
Missing POs, mismatches, inconsistent subcontractor formats, separate business entities, and recurring employee turnover made the workflow fragile. Blocked invoices could remain pending without clear ownership or follow-up.
Adding another clerk or using software alone would not have created one cadence for queue priorities, exception follow-through, entity coverage, customer-ready dispatch, and reporting.
