A Coupa migration introduced new systems and handoffs across 15+ entities. ARDEM documented process knowledge and kept daily invoice work moving. Automation support, manual exception handling and a live pending-invoice tracker helped the finance team manage the transition.
GLOBAL AP TRANSFORMATION AND COUPA MIGRATION CASE STUDY
Protecting AP Continuity Across 15+ Global Entities During a Coupa Migration
15+ entities
Global AP coverage
1,000+ / month
Processed during OCR training
20-30 / day
Manual exceptions handled
150 to 80 / week
Pending invoice reduction
Coupa transition AP workflow control is essential when invoice continuity, process knowledge, OCR training, supplier adoption, and pending invoice follow-up must continue during a finance systems change.
The Challenge
A retiring AP employee created knowledge-transfer risk at the same time the client’s global entity footprint and system environment were changing. Domestic and international invoices required tax rules, service-type coding, entity-specific handling, and continuity across 15+ entities.
The move from SAP Concur to Coupa created cutover exposure, vendor-by-vendor OCR training requirements, supplier portal adoption work, and a manual queue for scanned or non-native PDFs. Pending invoices also depended on purchase orders and business-unit inputs outside AP’s direct control.
The ARDEM Solution
ARDEM documented process knowledge, continued daily invoice execution, backed up unapproved Concur invoices before cutover, supported re-upload into Coupa, trained OCR fields, handled manual exceptions, processed employee expenses, and maintained a live pending invoice tracker.
The Coupa transition AP workflow combined automation enablement with human review and weekly governance, helping the client reduce pending invoices from approximately 150 to approximately 80 per week while maintaining global AP continuity.

Why ARDEM
Daily invoice execution continued while systems, people, and entity coverage changed.
Tax, coding, and handling rules were documented before institutional knowledge was lost.
OCR training was paired with manual review for files automation could not process.
Unapproved invoices were preserved and reloaded to reduce missed-invoice risk.
Live tracking, proactive follow-up, and weekly review kept blockers visible.
A managed model expanded across 15+ entities and multiple countries.How a Coupa Transition AP Workflow Protected Invoice Continuity
ARDEM managed the transition as a live finance operations workflow, not as a one-time software implementation task.
The Results
ARDEM helped the client turn a high-risk AP transition into a controlled operating model with clearer ownership, exception handling, and visibility.
- AP Continuity During System Transition
- Coverage Across 15+ Global Entities
- 1,000+ Monthly Invoices During OCR Training
- 20-30 Daily Manual Exceptions Controlled
- Pending Invoices Reduced From 150 to 80 Weekly
- Broader Expense Workflow Support
A Coupa Migration Did Not Remove the Need for AP Workflow Ownership
The client was managing employee transition, global growth, invoice continuity, and system migration at the same time. Each change introduced a different form of risk, from lost process knowledge to missed invoices and expanding exception queues.
Coupa improved the technology foundation, but OCR still needed vendor-specific training and supplier adoption. Scanned files, non-native PDFs, missing purchase orders, and delayed business-unit inputs still required human follow-through.
The Coupa transition AP workflow created the operating layer around the software. ARDEM connected documentation, invoice continuity, cutover control, OCR training, manual exceptions, expense support, and pending invoice governance.
The result was a more visible transition in which automation adoption could advance without leaving daily AP execution or exception queues unmanaged.

Tracked pending invoices and reviewed blockers weekly.
What You’ll See in the Full PDF
The full case study shows:
- How AP knowledge was captured before a key employee retired
- How unapproved Concur invoices were protected before cutover
- How Coupa OCR was trained vendor by vendor on core fields
- How 20 to 30 daily manual exceptions were handled
- How supplier portal adoption reduced manual forwarding
- How pending invoices moved from approximately 150 to 80 per week
- Why automation needed a managed human-in-the-loop operating model
