For companies, the biggest challenge in implementing a new procurement system is not the cost or lack of technology, but uncertainty. How can they be sure the investment will pay off? How can they know the software truly fits their unique business processes? The answer: a Proof of Concept (PoC).
A Proof of Concept is an initial implementation of a given idea or method whose primary purpose is to demonstrate the feasibility of the concept with minimal resource investment.
In the context of software procurement, this means proving that the chosen solution – and all its associated promises – actually works in the company's specific environment. This is not merely technical validation: a PoC also verifies whether the system can handle unique workflows, whether the promised time savings materialize, whether users truly accept the new tool, and whether integration with existing systems can be seamless.
A PoC conducted very early in the decision-making process – before significant time and financial resources are invested in full implementation – provides clear evidence that the software is viable in the given corporate environment and that the vendor's promises are well-founded.
This early preliminary validation ensures that only projects proven to be viable receive further funding. When an organization commits financial resources, it already has the certainty that the system fits its operations and that the promised benefits are realistic.
In the procurement decision process, the PoC is the first, most critical validation step. The main question it seeks to answer is: "Does this software work in OUR specific environment?" This is a short, 2-12 week test with real corporate data and processes. If this phase is successful, it's typically followed by a Pilot project, which tests the system on a larger scale with more users – asking not whether "it works," but whether "it scales" and "how it fits into the entire organization." Finally, during full implementation, the system becomes available to all users.
This gradual approach ensures that each step reduces risk before moving to the next, larger investment level. The PoC's role in this chain: to eliminate the greatest uncertainty at the lowest possible cost.
Risk Reduction: Identifies technical (does the integration work?), operational (does the system handle unique workflows?), financial (what will the total TCO be?, minimizes sunk costs), and change management (staff try out the system, reducing resistance) risks at the very beginning of the decision process.
Objective Decision-Making: Documented results – processing time, error rates, user feedback – are concrete evidence that helps win stakeholder confidence. Not promises, but measurable data.
Proof in Real Environment: Since real processes are tested with real data, after completing the PoC, a clear picture emerges not only of technical viability but also of business value.
Success is not measured by traditional project management criteria, but by whether it answers the key questions:
Clear Proof: Can the software handle the company's most critical process – whether that's complex integration, specific workflows, or unique data formats.
Negative Results Can Also Be Success: If it immediately demonstrates the software's unsuitability with minimal resource investment, this is actually a strategic success, as it prevents the waste of significant resources.
Disciplined Scope: It must provide focused, rapid answers to strictly defined questions. If the project drags on and slips into the Pilot phase, it means the loss of the PoC's original purpose.
Modern workflow platforms don't offer pre-manufactured processes, but rather a framework that adapts to unique processes. AI agents, low-code configuration, integrations – the possibilities are promising. But here's the critical point: these systems only show their true power when actually tried out by the specific company.
A generic demo can be misleading. It works with standard data and processes, follows a pre-prepared script, presents ideal conditions. It doesn't reveal integration challenges, doesn't show how the system handles unique cases, exceptions, non-standard formats.
The PoC, in contrast:
A PoC requires minimal resource investment, thus providing answers to critical questions at low cost. If it shows the software is unsuitable, the procurement decision can be changed without significant loss – this avoids the sunk cost trap. Furthermore, it provides a more accurate picture of how much additional energy the company needs to invest in implementing and maintaining the software, thus determining the total cost of ownership (TCO).
The short timeframe (2-12 weeks) enables agile decision-making: if necessary, you can quickly switch to an alternative solution.
Based on the results of a successfully validated PoC, a detailed implementation plan based on concrete experience can be developed. If it revealed infrastructure limitations or unique development needs, these become part of the plan – not speculation, but real knowledge.
The documented lessons provide comprehensive knowledge to the team, reducing the risk of further implementation. This organizational learning often extends beyond the specific project – it can be utilized in other digitalization initiatives as well.
In today's business environment, where uncertainty is increasing and every investment must be carefully considered, a Proof of Concept is not a luxury but a necessity. It is the cornerstone of software procurement strategy that resolves technical and operational uncertainties at the very beginning of the decision process.
For customizable procurement software, it's particularly critical: these platforms only show their true power when adapted to actual processes, data, and workflows. A generic demo will never provide the same level of proof as a targeted PoC running in a real environment.
The structured path – PoC, then Pilot, finally full implementation – ensures that software investment truly pays off with minimal risk, measurable results, and objective decision-making.
