The Business Management System (SGC) is an Integrated Management System focused on the commercial side of a business, like the Finance, Sales, and Purchasing departments. This system must be run on a computerized processing unit, such as laptops, tablets, and desktop computers.
The Business Management System's main function is to manage every department of the business — or at least the most important ones — at the operational, managerial, and strategic levels. For example, an employee can log a sale and process it via credit card. The manager, in turn, can know both which products are running low on stock and which accounts payable are overdue. The director, based on the information generated by the employee and analyzed by the manager, can decide whether the business should invest more in marketing, purchasing, etc.
A Business Management System shouldn't simply be installed on a computer and operated freely. Every business has different processes, and so must adapt to the system. On top of that, more advanced, complete systems require specialized training to maximize their day-to-day use. That's why a business should go through a few steps before using an SGC. Among them:
Research the solutions available on the market;
Assess, together with the companies' support teams, whether the system meets your needs;
Go through the purchasing process and subsequent implementation of the business management system; and
Complete specialized training.
The TagPlus team offers free training so customers can learn to use the system. But what if you still run into difficulties? Don't worry, you can take as many training sessions as you need; and the best part, for free and from the comfort of your own home!
What is the difference between an Online and a Desktop Business Management System?
An Online Business Management System is an SGC operated remotely through an Internet Browser. This system is stored on a computer/server located in a Data Center maintained by a specialized company.
Using the system even when there's no internet connection (Note: This doesn't apply to the TagPlus system, since it lets you make sales even without an internet connection);
