Fast transaction delivery makes it simpler for businesses to view sales figures and make decisions when necessary. The role and contribution of business actors in the Indonesian economy vary depending on their size; small and medium-sized enterprises can have a significant impact. Cooperatives and MSMEs account for 99.99 percent of all businesses in Indonesia. MSME business actors account for 14.17% of the country’s exports, 97 percent of energy work, and at least 60% of the GDP of the country." Before information systems, practically all work was done manually online and took a long time, so there’s a chance anything could go wrong that may be fatal [2].

Inventory is one of the operational challenges that stores often face. Inventory can be in the form of goods displayed in the storefront or stored in the warehouse. When there is too little inventory, customer demand may not be met, leading to disappointment and the possibility that customers will not return. Conversely, if there is too much inventory, the store may incur losses due to having to provide larger storage space, the risk of depreciation in the value of goods, as well as additional costs such as maintenance and accounting. Therefore, management must determine the right amount of goods to stock in the store. Management also needs to be careful in understanding the needs of customers so that they are satisfied and get what they are looking for.

To determine the right amount of inventory and understand customer needs, the management needs to conduct various studies. These include market surveys, analyses of sales data, observations of buying patterns, and analyses of the interrelationships of items that customers buy. One way to understand market conditions is to analyse sales transactions and process the sales data. With sales data, management can determine the number of items that need to be prepared in the warehouse, set minimum and maximum stocks for each item, decide when to place reorders, and determine strategies for slow-moving items and items that consumers are not interested in. Information on the relevance of purchased items can be used for marketing strategies and improving customer service.

The growth of information technology in this age of globalization has affected business in both positive and negative ways. Businesses are vying with each other to use information technology in an effort to improve customer service and performance, build a positive company reputation, and win contracts. The point of sale system is one piece of equipment that’s frequently utilized in the commercial services industry to improve transaction efficiency.

2. Related Work

Point of Sale (POS) systems are critical in modern retail and service environments, enabling efficient handling of transactions and improving overall operational management. Mulyana (2023) defines a POS system as an information system used in the sales process, involving machines that manage cashier operations and transactions in various businesses such as shops, hotels, restaurants, supermarkets, and retail outlets . The adoption of POS systems is prevalent due to their ability to streamline transaction processes and enhance the management of sales activities.

Maydianto (2021) discusses the transition from manual to automated systems, highlighting that prior to the introduction of information systems, most tasks were performed manually, which was time-consuming and prone to errors that could be detrimental . The implementation of POS systems addresses these issues by providing an efficient means of transaction processing, reducing the likelihood of mistakes, and saving time and resources [8].

One significant advantage of POS systems is their capability to generate comprehensive reports that facilitate better decision-making. By providing fast transaction processing, POS systems enable businesses to quickly access sales figures and make informed decisions when necessary. This feature is particularly beneficial for small and medium-sized enterprises (SMEs), which play a crucial role in the Indonesian economy. According to data, SMEs and cooperatives constitute 99.99% of businesses in Indonesia, contribute 14.17% to exports, provide 97 of employment, and account for at least 60% of the country’s GDP .

Inventory management is another operational challenge that POS systems help to address. Effective inventory management involves maintaining the right balance of stock to meet customer demand without incurring unnecessary costs. POS systems assist management in determining optimal stock levels by analyzing sales data, observing buying patterns, and conducting market surveys. This analysis helps in setting minimum and maximum stock levels, deciding on reorder points, and devising strategies for slow-moving items.

Leveraging POS data for predictive analytics offers various benefits for businesses beyond inventory optimization. POS data can reveal patterns in customer purchases throughout the year, such as increased demand for certain products during holidays or special events. This knowledge enables businesses to anticipate demand fluctuations, optimize inventory levels, and plan marketing campaigns accordingly. Overall, the ability to understand customer preferences, trends, and behaviors based on demographics is a valuable asset for businesses. By utilizing these insights, businesses can make data-driven decisions that enhance customer satisfaction, drive sales growth, and achieve a competitive advantage in the marketplace.

POS (Point-of-Sale) data is a valuable source of information that can be used to track individual employee performance, identify high-performing employees, and provide targeted training programs. This can help improve overall sales effectiveness and customer service, as demonstrated by the research of Li et al. (2017). Here are some specific ways in which POS data can be used to enhance employee performance: POS data can be used to track the number of sales made by each employee, the average transaction value, and the products or services they sell most frequently. By analyzing POS data, companies can identify employees who consistently exceed sales targets, provide exceptional customer service, or have low return rates. POS data can be used to identify areas where employees need additional training. For example, if the data shows that an employee has a high return rate, they may need training on how to handle returns more effectively. Companies can develop targeted training programs to address the specific needs of different employees. This training can be delivered in-person, online, or through a blended format. By tracking individual performance and identifying high-performing employees, companies can enhance overall sales effectiveness. Better trained and motivated employees can generate more sales and increase company revenue. By improving customer service, companies can increase customer satisfaction and encourage loyalty. Satisfied customers are more likely to return to the store and recommend it to others.

Data encryption is one of the essential elements in securing POS systems, but there are many other aspects to consider for building a truly secure system. A POS system should have strong access controls to limit data and functionality access only to authorized users. This can be achieved through the use of strong passwords, two-factor authentication, and different user roles with appropriate access levels. Employees should be trained on best security practices, such as creating strong passwords, not opening suspicious email attachments, and reporting any suspicious activity to a supervisor. Additionally, having a clear and comprehensive written security policy that outlines security procedures for the POS system is crucial. This policy should include protocols for handling data breaches, disaster recovery, and secure data disposal. Lastly, by implementing strong and comprehensive security measures, businesses can protect their POS systems from security threats and keep their customer data safe.

Modern POS systems are not only tools for processing transactions but also powerful instruments for collecting real-time customer feedback. Through brief surveys embedded in digital receipts and POS screen pop-ups, businesses can easily gain valuable insights into customer experiences and identify opportunities for improvement. Real-time feedback allows businesses to quickly identify customer service issues and address them promptly. For example, if many customers complain about long wait times, the company can take steps to hire more staff or improve the checkout process. Customer feedback can be used to identify popular and unpopular products and services. Companies can use this information to adjust their offerings and enhance the overall quality of their products and services. Additionally, feedback can be used to identify new features and services that customers desire. Companies can use this information to develop new products and services that better meet customer needs. Companies that actively collect and act on customer feedback have a competitive advantage over those that do not. Lastly, real-time feedback in POS systems is a valuable tool that businesses can use to improve customer satisfaction, enhance product and service quality, and strengthen their competitive edge. By proactively collecting and responding to customer feedback, companies can create positive customer experiences and foster customer loyalty.

Streamlining transactions and inventory management remain core functions, but the role of POS systems is evolving to encompass a more customer-centric approach. Modern POS systems integrate with various tools and technologies to personalize the shopping experience and foster customer loyalty in an omnichannel integration. POS systems bring significant transformation in how customers shop, creating a smoother and more connected experience across platforms. Customers can browse products online through websites or e-commerce apps, get complete product information, compare prices, and read reviews from other buyers. This easy access allows customers to conduct preliminary research and find products that meet their needs before visiting physical stores. Additionally, POS systems integrated with e-commerce platforms enable customers to check the real-time availability of products in physical stores. This helps customers save time and avoid disappointment when visiting stores and finding that desired products are unavailable. Customers can initiate product purchases online and choose either in-store pickup (click-and-collect) or home delivery options. Click-and-collect allows customers to conveniently and quickly pick up purchased products in physical stores, while home delivery provides convenience for customers who prefer to receive products directly at their homes. Furthermore, POS systems integrated with customer data from e-commerce platforms can offer personalized product recommendations based on previous purchases, browsing history, and customer interests. This increases the likelihood of customers finding products they like and boosts conversion rates. Omnichannel integration helps businesses manage inventory better by providing real-time visibility of product stock across all sales platforms. This allows businesses to avoid overstocking and understocking, ensuring the right products are available at the right time and enhancing operational efficiency. Finally, a smooth and integrated omnichannel experience can increase customer satisfaction and loyalty. The ease of shopping, flexible purchasing options, and personalization offered by integrated POS systems encourage customers to shop again and build long-term relationships with the business.

Integrating Internet of Things (IoT) devices with Point of Sale (POS) systems opens up exciting new opportunities for optimizing inventory management and enhancing operational efficiency. First, install IoT sensors on products and shelves to monitor inventory levels in real-time. This data can be integrated into your POS system, providing an accurate view of your product stock at all times.
