Evaluating the Quality of Point of Sale (POS) Software

Posted by Jim Walker

Many times when in the middle of the night or early morning, we wake up abruptly and feel the urgent need to know how much  and where is what we have invested in our company, cataloged or translated into tangible and intangible products, ignoring the volume of sales, profit margin, Management processes, and purchasing value, additionally without knowing  who our customers are and much less our suppliers …, the nightmare, the terror of commercial failure stuns us and we rush the next day to buy a system accountant or something similar that a friend or close family member recommends to us to help us support and justify the investments of the company. it is there where we find ourselves in a dead-end from which not even the most daunting circus contortionist takes out.

But when we look for a computer solution according to the rules of our business, with the help and professional advice of an accountant or a professional with knowledge in administrative areas and IT solutions, who knows and intuits where we are going with the company, we can find a route or a good path to move forward and find prosperity and abundance in running the company.   

It is important to carry out an evaluation of the quality of pos software – POINT OF SALE solutions that exist in the market, before making the respective investment, based on the application of the following premises:

The parameters for Evaluating the Quality of Point of Sale (POS) Software

The parameters that allow you to create quality pos software are divided into two families, often correlated with each other:

External parameters that define the quality perceived by the user:

Correctness:  that is the ability of the pos software to do exactly what it was designed to do, in some “agile” development modes, it also means customer satisfaction;

Robustness: means the measure according to which a pos software behaves reasonably in the face of unexpected situations, such as errors, interruptions, resets, or exceptions of various kinds;

Reliability: the concept of a reliable system that is, there is little chance of serious malfunctions;

Efficiency: that is the factor that measures the probability of deterioration of performance or of inefficiency in the use of resources;

Usability: usability is a subjective quality that indicates the simplicity of the system on the user side;

Eco- compatibility: eco-friendly pos software takes into account the impact on the environment in the design.

Scalability:  a system is scalable if it can be adapted to different contexts and different degrees of complexity, without the need to redesign the entire structure.

Internal parameters that distinguish the quality of software on the development side:

Verifiability: a pos software can be defined as verifiable if its properties are easy to verify.

Maintainability: that is the ease with which a system can be modifiable and re-adaptable.

Repairability: parameter given by the simplicity through which errors can be corrected.

Evolvability: the ability of a system to evolve and be modified.

Reusability: parameter very close to the concept of evolvability but more oriented to the ability to reuse components of one pos software to create another.

Portability: a system with this feature is able to operate in environments other than the native one. The application of a portable system allows a considerable advantage in economic terms, as the application is transportable and can be used easily in different environments.


The quality of a pos software is defined step by step in the production process and requires the combination of different design and development methodologies.
