Procure-to-Pay (P2P): Understanding the End-to-End Purchasing Process

What is procure-to-pay?

The Procure to Pay (P2P), also called Purchase-to-Pay, refers to the entire purchasing process from the expression of the need to the payment of the supplier.

This process is intended to allow businesses to acquire the necessary goods and services at cost while optimizing margins at each stage.

To achieve this, they must set up a structured purchase flow, covering all stages: definition of needs, selection of suppliers, negotiation, contracting, receipt of invoices, and payment.
‍

The steps of the Procure to Pay (P2P) cycle

The Procure to Pay (P2P) cycle is generally based on 7 key steps, widely disseminated through specialized solutions and good industrial practices:

1. Identification of the need

A department detects a need for goods or services in line with the company's goals and budget. This first phase is essential to avoid superfluous or unbudgeted purchases.

2. Request Management

The need is formalized in the form of a purchasePurchase request, subject to validation. It may include product research, shopping carts, and budget receipts. Approval guarantees internal and budgetary compliance.

3. Creation and issuance of the order form

After approval, a purchase order is generated and sent to the supplier. This contractual document specifies quantities, prices, deadlines, and conditions.

4. Receiving goods or services

Upon delivery, a receipt note is generated. The company verifies the conformity, quality, and quantity of the products or services received.

5. Receiving and processing the bill

The supplier dispatches an invoice, which the system records. It is then aligned with the PO and the receipt of goods (process of three-way matching).

6. Approval and payment of the invoice

The invoice is validated if no discrepancies are detected. Then, it is sent to the accounting department for payment according to the contractual terms (bank transfer, card, etc.).

7. Closing and updating accounting

The process is completed with payment confirmation, complete registration in the accounting system, and supplier performance monitoring. This data feeds into reports and analyses.

The challenges of procure-to-Pay for businesses

A well-orchestrated Procure-to-Pay process represents a strategic lever for improving the overall performance of a company.

Reduced operational time and costs

By eliminating manual interventions (entries, reminders, reconciliations), businesses save time and reduce administrative costs. The ability to handle a larger volume with the same resources directly improves productivity without burdening teams.

Strengthening compliance and traceability

Each action (validation, approval, modification) is traced, facilitating audits, fiscal audits, and internal controls. Compliance with contracts and payment deadlines is also becoming more systematic.

Optimization of cash flow and working capital

Precise management of supplier deadlines makes it possible to anticipate disbursements, negotiate discounts, or delay payments without the risk of penalty.

Improving supplier relationships

By respecting payment deadlines and facilitating documentary exchanges, the company strengthens its reputation and position in the supply chain.

The risks of a poorly controlled P2P process

On the other hand, a poorly structured or too manual P2P process exposes the company to numerous flaws, both operationally and strategically.

Administrative inefficiency

Repetitive and non-automated tasks, such as manual data entry or email reminders, slow down daily operations. These delays weigh on teams, increase the risk of errors, and hinder business agility.

Uncontrolled expenses

The absence of formalized procedures can lead to out-of-process or unauthorized purchases, often outside of negotiated agreements. These practices reduce visibility on commitments, complicate budget monitoring and can generate unnecessary additional costs.

Degradation of supplier relationships

A poorly managed P2P delays invoice processing, causing late payments, penalties, and tensions with suppliers. The lack of visibility into transactions or structured communication can also lead to disputes that are difficult to resolve.

Increased risk of errors and fraud

Manual or insecure processes facilitate input errors and expose the company to fraud: duplicate payments, fictional invoices, unvalidated suppliers, etc. Without a robust control system, these incidents can have a heavy financial and reputational impact.

How to optimize your procure-to-pay (P2P) process?

Optimizing the Procure-to-Pay (P2P) cycle is a strategic lever for gaining operational efficiency, reducing costs, securing transactions, and strengthening supplier relationships.

1. Digitize and automate P2P workflows

The transition from a manual process to digital management makes it possible to streamline each stage: purchase requests, approvals, orders, receipts, invoices, and payments. Thanks to automation:

• Validation flows are accelerated;
• Repetitive tasks are removed;
• Input errors are reduced;
• Processing times are shortened.

Solutions centralize all documents (order forms, invoices), automate their collection, and guarantee rigorous monitoring on a unified interface.

2. Integrate P2P into your information system

Businesses have two approaches:

• P2P modules integrated into the ERP (SAP, Odoo, Oracle...) ensure consistency between purchasing, accounting, and cash flow data.
• Specialized P2P solutions (Coupa, Ivalua, Basware...) offer advanced ergonomics and specific functionalities: supplier portals, digital catalogs, integrated indicators, etc.

Regardless of the option chosen, the challenge is to ensure a smooth integration with the existing information system to avoid duplicates and ensure digital continuity.

3. Automate document processing using OCR and IDP

The integration of technologies such as OCR (Optical Character Recognition) and IDP (Intelligent Document Processing) allows:

• Automatic extraction of data from supplier documents (invoices, purchase orders, deliveries);
• The automation of reconciliations;
• The reduction of processing times;
• Paperless management, more reliable and secure.

Smart platforms like Koncile combine OCR and intelligent processing for Automatically classify, extract, and structure data complex documents. They make document processing more fluid, while facilitating the direct integration of information into accounting or ERP systems.

4. Manage cash flow and anticipate payments

Optimizing P2P also requires better financial visibility. Visualizing the deadlines in a cash flow plan allows you to:

• Better manage the DPO (Days Payable Outstanding) ;
• Avoid delays or penalties;
• Schedule payments at the most appropriate time.

Thanks to certain solutions, it becomes possible to adjust disbursement flows in real time according to available cash flow.

5. Ensuring the quality of supplier data

A clean and structured supplier framework is fundamental. It is essential to maintain:

• Unique and up-to-date supplier sheets;
• Verified banking information;
• Valid VAT numbers.

One clear data governance, with defined roles, controls and validations, reduces the risks of fraud, avoids payment errors and makes analyses more reliable.

6. Track relevant KPIs to measure performance

Performance analysis allows for continuous improvement. Key indicators include:

• The average invoice processing time:
• The successful automatic reconciliation rate;
• The rate of compliance with payment deadlines;
• The level of users' adoption of tools.

These KPIs make it possible to identify “bottlenecks” and to optimize processes continuously.

7. Strengthen internal and external collaboration

An effective P2P process is based on fluidity of exchanges :

• Between the purchasing, finance and accounting departments;
• With suppliers through dedicated portals.

Allowing everyone to access up-to-date information, track transaction status, or submit documents online improves productivity and partner satisfaction.

FAQ—Everything you need to know about the Procure to Pay (P2P) process

1. What is the difference between Procure-to-Pay (P2P) and Source-to-Pay (S2P)?

P2P only covers the operational chain from the purchase request to the supplier's payment. As for S2P, it includes strategic sourcing at the outset, i.e., the selection, evaluation, and contracting with suppliers. In summary, S2P encompasses P2P with a broader vision of procurement strategies.

2. Would it be possible to automate a P2P process without changing ERP?

Yes, there are modular P2P solutions that can integrate with existing ERPs without replacing them. These tools use connectors or APIs to synchronize data in real time, making it possible to benefit from automation without changing the company's IT architecture.

3. How to assess the return on investment (ROI) of a P2P project?

The ROI of a P2P project can be measured through several indicators: reduction of processing times, reduction of administrative costs, improvement of the compliance rate, reduction of supplier disputes, or even cash flow gains. A before-and-after analysis over a few months is often enough to demonstrate tangible benefits.

4. What are the impacts of an effective P2P on audits and internal control?

A well-structured P2P process makes audits much easier, whether internal or external. The traceability of each stage, the archiving of documents, and the standardization of flows make it possible to quickly meet the requirements of auditors and to prove the conformity of expenses.
