Key Considerations for your Procurement Platform Implementation

A winning game plan makes all the difference

Implementing a procurement platform alongside an ERP system and tax engine is a complex undertaking. Tax, finance, and IT teams each have a stake in the outcome. When any one group is left out of the planning process, costly problems follow. This white paper organizes the key questions your project team needs to work through, quarter by quarter, so nothing critical slips through the cracks.

Start with the fundamentals

Before implementation begins, your team should assess how tax automation currently fits into your environment. Is Vertex Indirect Tax O Series already integrated with your ERP system, or is that integration part of the current project? Was the tax team involved when the procurement platform was selected? If not, that is an early warning sign. Tax is often the last group to find out about a new platform, and that gap can limit access to the data needed for compliance and risk mitigation.

Understand how procurement will be used

Not all spend is the same, and your platform needs to reflect that. Procurement platforms are built for indirect spend (things like office supplies and laptops). Using them for direct spend, such as items in a manufacturing process, creates tax risks your team needs to anticipate. You also need to know where invoice payments will be processed and confirm that the ERP system will serve as the authoritative source of accounting truth. Procurement platforms cannot fulfill that role on their own.

Work through the technical and process details

The procure-to-pay cycle introduces specific points where tax calculations can go wrong. Self-assessed tax moving from a procurement application into the ERP via a payment file is one area that deserves close attention. Inventory movement and goods handled across multiple locations are another. Tax calculations in these scenarios often need to happen in the ERP system, not the procurement platform, because the determination depends on location data that most procurement tools do not have.

Define your reporting requirements early

Reporting is often addressed too late in the process. Your team should agree upfront on how indirect tax for procurement will be reported, whether returns are filed internally or through a third party, and what audit information needs to be captured and in what format. If relevant tax data lives across multiple systems, you need a plan to bring it together for compliance purposes, including input tax credits for value added tax.

Preparation is the real competitive advantage

Working through these questions before and during your implementation reduces surprises and keeps the project on track. The more alignment your tax, finance, and IT teams build early, the better positioned you are to handle whatever comes up along the way.
