Choosing an eProcurement Solution: ERP Integration & Costs in 2026

Choosing an eProcurement solution is one of the most momentous decisions you can make for your purchasing department. This is because the right platform not only saves process costs - it also changes how your entire company procures. At the same time, the solutions available on the market differ considerably in terms of their integration capability, their degree of automation and their suitability for industrial companies.

This guide takes you through the most important evaluation criteria, shows you what is important when it comes to ERP integration and explains how you can realistically estimate the total cost of ownership. simple system helps industrial companies to bundle their procurement processes in one place - with a turnkey SAP interface and end-to-end automation right through to accounting.

Key findings: Selecting eProcurement

• Reliable ERP/SAP integration is the backbone of any successful eProcurement implementation in industrial companies.
• The degree of automation determines how much process costs you can actually save per order.
• Good supplier management reduces maverick buying and creates transparency across all expenditure.
• simple system enables you to save up to 150 euros per order through automated processes.
• In addition to license costs, the total cost of ownership also includes implementation, training and ongoing operation.

Why eProcurement is so important for industrial companies

Industrial companies with 500 to 5,000 employees face a particular challenge: procurement processes often run across several locations, different departments and different systems. This leads to high transaction costs, a lack of transparency and uncontrolled purchases outside of approved channels.

An eProcurement platform bundles these processes. It enables users to order independently, while strategic purchasing retains control. According to the BME SME Purchasing Barometer 2024, 60 percent of SMEs have already digitized their procurement processes - but 33 percent still do not have any digital processes for supplier qualification.

How to evaluate the ERP integration of your eProcurement solution

The connection to your ERP system determines whether your procurement processes really work end-to-end. Without a functioning interface, media disruptions occur: orders have to be transferred manually, error rates increase and the accounting department loses the overview.

When selecting a solution, make sure that it offers a turnkey interface for your system - especially for SAP environments. simple system provides a ready-made SAP connection that automatically transfers order and BANF data. This means that purchasing, merchandise management and financial accounting work with the same data, without manual input.

Which questions you should clarify for the ERP connection

Ask specifically whether the solution supports OCI punchout, how order data is transferred to your ERP and whether goods receipt and invoice data can be automatically reconciled. The more of these processes are automated, the less manual work you will have to do in your day-to-day business.

Automation in purchasing: these functions count

Automation determines how much time and money you actually save. Key functions include approval processes, automatic account assignment and the transfer of order data without manual intervention.

With a well-configured platform, it is sufficient for the requisitioner to place items in the shopping cart. Everything else - from approval and budget checks to posting - runs automatically. simple system automates order processes in a standardized way right through to accounting, saving up to 150 euros per order.

How to recognize the actual degree of automation

Check which manual steps are still necessary after ordering. Do cost centers have to be assigned manually? Are goods receipt postings carried out automatically? Are invoices reconciled without intervention? The less manual work, the greater your savings potential.

Supplier management: create transparency across all expenditure

Centralized supplier management prevents orders from bypassing unchecked or unapproved suppliers. You can see at a glance which suppliers you are buying from, on what terms, and where there is potential for bundling.

This transparency is particularly important when procuring goods such as office and IT equipment or MRO (maintenance, repair, operations) items. A platform that manages all suppliers centrally and makes their product ranges directly accessible reduces maverick buying and strengthens your negotiating position.

Total cost of ownership: how to calculate realistically

Comparing eProcurement solutions on the basis of license costs alone is misleading. The total cost of ownership (TCO) includes much more: implementation costs, training, ongoing maintenance, internal resources for administration and any adjustments.

Ask potential providers for a detailed TCO model. How long will the implementation take? What internal capacities are required? What costs will be incurred for updates or the connection of additional ERP systems?

What hidden costs you should be aware of

Hidden costs often arise due to a lack of integration capability. If your IT department has to program interfaces individually or data has to be synchronized manually on a regular basis, operating costs increase quickly. A platform with standardized interfaces saves money in the long term.

What is important when it comes to user-friendliness

The most technically sophisticated solution is of little use if your employees don't use it. An intuitive interface, quick article search and mobile accessibility ensure that users accept the platform on a daily basis.

Pay attention to whether the solution offers a central dashboard that shows order status, budget utilization and open approvals at a glance. The easier the access, the higher the acceptance - and the lower the risk of employees bypassing the platform when ordering.

Checklist: These criteria belong in your evaluation matrix

When comparing different eProcurement solutions, a structured evaluation matrix can help. You should cover the following criteria:

• ERP/SAP integration: is a turnkey interface available?
• Degree of automation: Which process steps run without manual intervention?
• Supplier management: Can you manage product ranges, prices and approvals centrally?
• User-friendliness: Is the interface intuitive and mobile-friendly?
• TCO transparency: Are all costs - implementation, training, operation - traceable?
• Scalability: Will the solution grow with your company?

Conclusion: How to find the eProcurement solution that suits your company

Choosing the right eProcurement solution depends on how well it fits with your existing systems, processes and goals. Prioritize a reliable ERP integration, check the actual level of automation and calculate the total cost of ownership realistically.

If you are looking for a platform that bundles your purchasing processes in one place and works with a turnkey SAP connection, it is worth taking a look at simple system.
