MEDIUS SOLUTIONS

Connect the Purchasing-to-Payment Journey

Medius gives organizations an opportunity to think beyond invoice automation and connect more of the purchase-to-pay lifecycle—from the initial request and approval through invoice processing and supplier payment.

Lyndon Group helps organizations prepare the business for that transformation.

Our team brings decades of experience across finance, accounts payable, invoice management, payments, spend management, integrations, controls, reporting, and enterprise program delivery. We apply that experience to Medius engagements to help clients connect technology decisions with the people, processes, data, and operating practices required to make them successful.

For organizations beginning with AP automation, we can help build the foundation today while keeping the broader procure-to-pay journey in view.

A Broader View of Spend Transformation

From AP Automation to Connected Procure-to-Pay

Accounts payable is often where organizations feel process inefficiency most clearly—but many of the issues that surface in AP begin earlier.
Purchase requests, approvals, purchase orders, supplier information, receipts, invoice matching, exceptions, payments, and reporting all depend on connected processes and reliable data.

Medius brings these activities together across a broader purchase-to-pay platform. Lyndon Group helps clients understand how that connected environment affects finance operations, internal ownership, integrations, controls, adoption, and day-to-day work.

Our deepest delivery experience today is in the finance, invoice, payment, integration, and operational components of this lifecycle. As our Medius practice expands, we are applying those established capabilities across increasingly connected P2P initiatives.

The P2P Program Perspective

One Process. Multiple Business Functions

A successful procure-to-pay program crosses organizational boundaries. Lyndon Group helps clients bring the right stakeholders, requirements, and operating decisions together across the lifecycle.

Purchase & Approval

Support business requirements, approval design, policy alignment, ownership, data dependencies, and the change required as purchasing activity becomes more structured and visible.

Invoice & AP Automation

Improve invoice capture, matching, workflow, exceptions, processing, controls, reporting, and touchless automation.

Payment

Connect approved invoices to controlled supplier-payment processes with appropriate approvals, visibility, reconciliation, and financial oversight.

Data & Integrations

Coordinate the information moving between Medius, ERP, procurement, supplier, banking, payment, and reporting environments.

Controls & Governance

Help define ownership, approval requirements, documentation, exception handling, accountability, and operational governance across the process.

Users & Adoption

Prepare requesters, approvers, AP teams, finance leaders, administrators, and other stakeholders to work effectively in the new process.

A Growing Partnership Built on Established Trust

Lyndon Group’s Medius partnership is supported by long-standing professional relationships, shared industry experience, and complementary expertise.

That working relationship gives clients a coordinated model in which Medius provides the platform and specialized product enablement while Lyndon Group can lead or support the broader business, functional, project, and organizational work surrounding the deployment.
