There have been a host of technological advancements in recent history that have contributed greatly to increasing the quality and efficiency of the service industry. As societies entered an era of post-industrial revolution, the technologies used in everyday financial transactions had to become more sophisticated to meet the growing demands of consumers. One of those technologies that are used with some variation in almost all supermarkets, drugs, and other types of stores is the point of sale software.

Point of sale software development begins with the first technologies present at a point of transaction. Financial transaction technology began with a simple exchange of goods by hand, to a currency exchange by hand, to a simple cash register, and finally to an electronically sophisticated cash register equipped with point of sale software. It was in 1992 that modern POS software came to the fore with Martin Goodwin and Bob Henry developing software that could run on a Microsoft Windows system. From that point on, point of sale software has become increasingly user-friendly and cost-effective (one can expect to pay $ 4,000 for a system), with all systems defined by their fast speed and variety of useful functions for any business. 

Customer service has become an industry that demands efficiency and therefore it is important to have a checkout system that is easy to use for both management and employees. Point of sale software can be easily customized according to the demands of a variety of industries. For example, the retail industry derives great benefits from implementing point-of-sale software and is subsequently one of the largest consumers of these systems. The combination of a computer, monitor, cash register, printer, display system, and scanner is complex enough that software is required to simplify transactions. Increasingly, point of sale systems includes all-in-one touch screen monitors that can handle all the functions necessary for a retail employee; returns, exchanges, gift cards, sales, discounts, etc. Not only does this allow retail stores to save valuable space, but it also gives managers and owners the ability to track all transactions to identify areas for needed improvement and tailor their future purchase orders. This type of software is also very popular in the hotel and restaurant industry to keep up with an increasingly fast-paced set of consumer demands. This includes demands for special customer loyalty offers and a growing variety of payment methods.

Additionally, point of sale software enables retention of customer information for delivery, more efficient checkout, and easy credit setup. This same system can be used to store and organize employee information and track employee sales, hours, and commissions. This ensures the responsibility of employees to properly record hours and earnings, as well as providing the opportunity for incentives to encourage sales. This may seem like a "big brother" situation indicating a lack of trust in employees. However, it is a product of the modern capitalist market, which along with its liberating economic effects, has also introduced a culture of vigilance. Every aspect of a person's life is electronically recorded and monitored, be it purchase records, criminal records, or the storage of her identity (via a driver's license, passport, etc.). Therefore, companies and other organizations need to use this monitoring technology to their advantage. Ultimately, using this technology to optimize efficiency will reward employees who perform at their best.

It is due in large part to the development of electronically sophisticated point of sale software that the customer service-oriented industry can provide the friendly and efficient service that is possible today. Without tracking and organizing inventory, storing customer records, and monitoring employees, many of the stores people frequent would be noticeably less competitive. In a market where being able to stay competitive is key, this would be a great weakness. Whatever your business needs; a point of sale system is a smart investment.
