What does procure-to-pay consulting cover, and when do you need it?

What is procure-to-pay consulting?

Procure-to-pay consulting is outside help with the part of procurement that starts when an employee needs to buy something and ends when the supplier is paid. The consultant works on the process and on the software: how requests are approved, how orders and receipts are recorded, how invoices are matched, and how the platform talks to the ERP that pays.

Procure-to-pay is the second half of source-to-pay. The first half, source-to-contract, covers suppliers, tenders and contracts. Ivalua draws the line in a similar way on its own site: eProcurement manages how you buy, from requests and catalogues to orders and approvals, while procure-to-pay adds invoices and supplier payments. If your project covers the whole chain, source-to-pay consulting explains the four moments when you need help.

For the process itself, step by step and with no vendor angle, eProcurement Toolkit’s procure-to-pay guide starts from the basics. This page is about the consulting work around it.

What does a procure-to-pay consulting engagement cover?

We read the pages where consulting firms describe their procure-to-pay work: Fluxym, The Hackett Group, and the UK government G-Cloud listings of BearingPoint, KPMG and Capgemini. They name the same eight blocks. Each block below was named by at least two of these firms. The right-hand column shows what the block looks like on a real project.

Public contracts confirm these blocks. Ivalua’s 2023 master agreement with the State of Maine asks for three-way matching, an integration with the finance system, hosted catalogues or punchout to suppliers’ web shops, and interface development as part of the implementation services.

When do you need a procure-to-pay consultant?

You need one when the process or the platform changes, or when it stops working and your team cannot say why. These are the usual situations:

• You add procure-to-pay to a platform you already use for sourcing or contracts. The catalogues, the approval rules and the ERP interfaces are new work, with new users in every department.
• Invoices wait between the platform and the ERP. For example, the platform sends approved invoices to the ERP, and the ERP sends back the payment status. When one of these flows fails, suppliers call accounts payable to ask when they will be paid.
• Your ERP changes. A move to a new ERP means every order, invoice and supplier flow must be specified, built and tested again.
• You must receive e-invoices. Suppliers have to be invited, invoice formats checked, and the matching rules adapted.
• Each upgrade takes longer. An approval rule built for one entity only still has to be retested at every upgrade. When a platform drifts like this, users go around the tool and reports need manual fixes.

In each case, the consultant must understand both the procurement process and the systems. A process expert who cannot read an interface specification, or a developer who does not know why a receipt is needed before an invoice is paid, will each solve only half of the problem.

How do you know if your procure-to-pay process needs help?

Compare a few figures from your own process with public benchmarks that publish their method. Few do. These are the ones we could check:

Be careful with savings figures. The Hackett Group shows an 80% lower procure-to-pay process cost for what it calls AI World Class organisations, but its own page says this comes from modelling scenarios based on peer medians. They are targets from a model, not results measured on real projects.

How long does procure-to-pay consulting take?

It depends on the scope, and no neutral source publishes a typical duration. The figures that exist come from vendors and integrators, so read them as their own claims:

• In March 2019, Ivalua launched a packaged procure-to-pay offer of 8 to 12 weeks, and cited a healthcare customer live in 8 weeks.
• CKS Consulting, a French Ivalua integrator, gives 8 to 10 months for a procurement system project, from scoping to deployment.

The ERP interfaces and the supplier set-up depend on teams outside the project, so put them in the plan from the start. For Ivalua costs and durations taken from public contracts, see Ivalua implementation cost and timeline.

Procure-to-pay consulting firm or independent consultant?

First check that you are buying consulting. In October 2026, the service pages Google shows for “procure to pay consultants” come from three firms. GEP and WNS describe outsourcing: their teams process orders, invoices and payments for you. Fluxym describes consulting, implementation and support on P2P software. Outsourcing runs your transactions; consulting changes your process and your platform.

If you need consulting, the choice depends on the size of the work. A large firm fits a programme across many countries that needs many people at once. An independent consultant fits one role or one workstream, when you want the person you interviewed to do the work.

Firms and independents are not priced the same way. In the UK, contract job ads that mention procure-to-pay show a median of £554 a day (134 rates, six months to 27 October 2026). KPMG’s rate card in the public G-Cloud catalogue lists £2,150 a day for an “Ensure, advise” consultant (April 2024). The two figures do not measure the same thing: a firm’s rate covers its own structure, and an ad rate may include an agency’s margin. Market day rates, contract routes and the checks before you sign are in how to hire a freelance procurement consultant.

How do I work on procure-to-pay inside Ivalua?

I am a certified Ivalua consultant (L1, L2 and L3), and all my services are on Ivalua. I have worked on three full-cycle Ivalua implementations at BNP Paribas. The first, v156, built the group’s source-to-pay platform, including the catalogue, the workflows and e-procurement. On the current one, v182, delivered and still evolving, my work includes the supplier and ERP interfaces, the catalogue, the data flows between systems, and advanced SQL for reports and controls.

On the procure-to-pay side of Ivalua, this is the work I do:

• ERP interfaces. Each flow is specified, built and tested from end to end: orders, invoices, payment status, supplier records. The Ivalua ERP integration guide shows the usual flows.
• Catalogue and workflows. Catalogue content, approval rules, and the exceptions that each entity asks for.
• Data checks. SQL reports and controls, so that procurement and finance trust the same figures.
• Rollout. Change management and user support when each entity moves to the platform, in France and abroad.

Ivalua’s procure-to-pay modules are described in Ivalua modules, and the supplier side in the Ivalua supplier portal. Under Ivalua’s 2023 contract terms, configuration needs Level 2 certification and integrations need Level 3.

On a procure-to-pay project, I join on a senior mission, as a techno-functional lead inside your team, at a day rate given in a written proposal. When one person is not enough, I lead an Ivalua team of certified consultants from my network. To agree the scope, book a call or write to me.
