“It’s worth noting the following advantages of working with 4Service Group: – User friendliness of “Shopmetrics” platform. – A large base of mystery shoppers, thus facilitating “rotation” standards. – Flexibility and high-professionalism of the project team. As a result of our experience, UniCreditBank would like to fully recommend 4Service Group as a reliable and competent Mystery Shopping provider.”


“The polls are carried out with a certain frequency in order to keep track in time; the procedure has been done for decades. We conduct them once in half a year, measure brand knowledge, brand attitude, consumer perception of price level, quality level compared to specific competitors as well as how our consumers perceive the level of service in the store, that is, we evaluate all the factors. ”


“A large base of mystery shoppers allows evaluating the quality of service with the coverage of the whole country. Comfortable functionality of the report-system allows producing the statistic data in the frame of each store and consultant, in addition to the questionnaire components. Such a method of data flow allows to rapidly monitor the level of service, as well as to provide prompt feedback to our employees. All of the above help us to greatly increase the level of professionalism.”


“We started out with an open audit concept. But this concept did not reflect our real goals. In other words, the customer’s point of view was missing from the equation. And then we decided, after receiving the first results from our Russian colleagues, to start afresh with mystery shopping as a new tool to improve our sales performance.”

A payment process is an important component of any application developed for receiving payments from consumers. Consequently, you must carefully review this procedure. Any trouble scenarios or defects in operation may affect the seller’s sales or transactions, and adversely affect shopping experience for a consumer.

Payments Testing: Why Is It Needed

When customers make payments in a store, POS terminal confirms or declines it. The same happens with transactions proceeded online.

A client expects that e-payment transaction will be processed without any delay. After consumer presses confirmation button, in a few seconds a notification appears showing if a payment was successful or declined.

A seller needs to check if the entire payment process (transaction in online store, authorization, etc.) is working properly. If a problem arises at any stage, the seller will face problems, too.

Conducting test card payment makes possible inspecting operator’s workflow and determine if selected options are the best choice for work performance and operating an application.

Test Payments Types

Depending on payment operator, type of goods and application, subsequent types of tests could be needed:

  • Functional Testing is considered the most important type of software testing. It gives complete information about the current state of a product, as well as detailed description of defects found, and recommendations on how to eliminate them.

Functional software testing will help you to:

  • check the correct operation of application under various conditions of use, including testing time payment;
  • check product compliance;
  • analyze the level of software quality and prioritize the defects found in accordance with the degree of criticality.
  • Integration Testing. Integrated solutions allow users to establish connection between them via API for online store. In other words, a client pays without switching to third-party resources. On the one hand, this is convenient because it will not reduce the conversion rate. And on the other, you are responsible for the security and safety of client data. Therefore, most likely you will need the help of a developer to provide such payment system with necessary level of security.
  • Performance testing. Failures in product performance can adversely affect your business. Software stress testing is an opportunity for preventing failures in its work and ensuring stable functioning of all components. We will identify current problems and identify hidden defects that may adversely affect the operation of software.
  • Security testing is aimed to:
  • minimizing risk of loss, distortion, data theft;
  • unauthorized Access Prevention;
  • Online Transaction Security Check;
  • increased resistance to DoS attacks;
  • Penetration Testing.


Today, amid ever-increasing volumes of bank card emission, issues of increasing the effectiveness of quality control of manufacturing and personalization of card products are coming to the fore for issuers. It is especially important to emphasize the ability not only to sift low-quality products, but also to work for minimizing defective items. Scheduling Worldwide is ready for providing everything necessary for solving this critical task for both large customers and small companies.
