Thesis about Computerized Payroll System for Barangay Hall, Dita

  1. 1. A Computerized Payroll System for the Barangay Dita 1.1 Background of the study HISTORY OF PAYROLL SYSTEM A computerized payroll system, the employer invests in a computerized payroll software. Using a software such as quickbooks allows the employer to enter the wages into the system after he has manually calculated them. The payroll and check printing are processed through the system. The employer has access to payroll reports that he/she can print and use to double-check against what she has entered before printing the checks. This allows his/her to correct any detectable errors beforehand. Computerized payroll system allow you to process all your normal payroll task via a computerized system, rather than by hand. Essentials like name, address, Social Security number and withholding rate for each employee are automatically filled in for every pay period until you make an employee’s record inactive. Many different vendors offer computerized payroll system. Like different word processors or other computer programs, they largely offer the same types of features with slightly different interfaces. Payroll is essentially how employees are paid. It’s the legal paperwork involved. There's more to payroll than just handing out cash or checks. However, after gathering data on what the employees did and compared it to their salaries, some simple payday mathematics will let the employer hand out the dough. 1.2 Objectives 1.2.1 General Objective The main objective of the study is to design and develop a Computerizes Payroll System for Barangay Hall, Dita that fast transactions, minimize the manual checking of employees, monitor the status of employee’s charges, deductions and generate the essential reports. A computerized payroll system must be able to keep and generate accurate reports on employee income. An equally important objective of any payroll system is to generate paychecks and pay stubs. Computerizing this task saves managers and business owners time and money; rather than reviewing time cards manually and calculating a check amount based on the hours worked, the payroll system should be designed to automatically calculate these figures. A computerized payroll system must automatically factor in the overtime pay. This helps employers stay within the law when it comes time to pay overtime. Additionally, since an employer can use the system to check the number of hours an employee works, the employer can shift schedules to avoid paying additional overtime. 1.2.2 Specific Objectives To minimize the manual checking of each daily time record.
  2. 2. To develop a module that will generate essentials reports. To develop that will monitor the status of employee’s loan and other deductions such as cash advance and charges. 1.3 Significance of the study This part of the study discusses about the importance of creating computerized Payroll System. It provides sample discussed how to run a Computerized Payroll System and here are some examples of how it run. Many employers use a timekeeping system, such as clock time, to track work hours employees '. Can separate this system regular hours from overtime hours worked. Payroll all people will do is make edits / adjustments, if necessary. If time employees are imported into the computerized Payroll system, the latter rounds up and down time employees appropriately, as the nearest quarter hour. It calculates the total hours worked and paid. It is saving the time spent manually calculating time and reduces errors. If the person enters Payroll time system itself, automatically calculates its income, based on its input. The system calculates all pay frequencies, such as weekly, biweely, and twice a month. Only people attended Payroll data which the reduction is based, such as form for withholding information federal income tax. Necessary you a manual payroll system to print paychecks on a typewriter or by hand. A computerized Payroll system has direct deposit capability, which saves money spent on live checks and reconciliation. Moreover, paycheck and pay stub generation occurs rapidly, regardless of the quantity. developing a computerized system and Prints Payroll reports . If you want to double - check before printing Payroll stubs paychecks / pay, just refer to the corresponding report. A computerized payroll system allows hard - copy printing of Payroll registers pertaining to each pay period. Also saves its information systems without boundaries .The system generates reports to ensure compliance with tax Payroll tax. This includes quarterly and annual wage reporting and development of employee forms. If a related departments such as accounting office holding Payroll taxes and reconciliation of the company, print the required reports would require the department through the computerized system. Furthermore, these days, such as vacation and personal time, taken and paid to benefit the track system . 1.4 Scope The study will covers the process of preparing the pay slip of each employee, monitors loans, cash advances, charges, keeping the records and easily computers the basic pay, regular overtime pay, pay during day off, special and legal holiday pay, gross pay, SSS contributions, PhilHealth contributions, Pag-Ibig contributions, cash advances, charges, deductions, lates, and net pay. 1.5 Delimitation The study does not cover any other not employee of the Barangay Hall, Dita .This is not a group pay slip. This system is not cover by any deduction that may not belong to the pay slip. And also the other income that not belong in Barangay Hall, Dita .
  3. 3. 1.6 Definition of Terms 1.6.1 Operational Terms Computerized Payroll System- A computerized payroll system has many prominent advantages over paper systems. They prevent clerical error in calculating hours and a gross payment. They also automatically deduct taxes based on the gross payment. Work Hours- is the period of time that an individual spends at paid occupational labor. Unpaid labors such as personal housework or caring for children/pets are not considered part of the working week. Overtime hours- is the amount of time someone works beyond normal working hours. Normal hours may be determined in several ways. Regular Hours- is usually when a store opens and closes. Total Hours- compute the number of hours you work every week counting overtime and then average these hours over a set period. Income Tax- is a government levy (tax) imposed on individuals or entities (taxpayers) that varies with the income or profits (taxable income) of the taxpayer. Details vary widely by jurisdiction. Many jurisdictions refer to income tax on business entities as companies tax or corporation tax. Deposit- account is a savings account, current account, or other type of bank account, at a banking institution that allows money to be deposited and withdrawn by the account holder. Paychecks- is traditionally a paper document (a cheque) issued by an employer to pay an employee for services rendered. In recent times, the physical paycheck has been increasingly replaced by electronic to bank accounts. Such employees may still receive a pay slip, but any attached cheque is marked as non-negotiable and cannot be cashed. Payslip- a slip of paper included with your pay that records how much money you have earned and how much tax or insurance etc. has been taken out. 1.6.2 Technical Terms Data- is a set of value of qualitative or quantitative variables; restated, data are individual pieces of information. Data in computing or data processing are represented in a structure. Data consists of a series of facts or statements that may have been collected, stored, processed and/or manipulated but have not been organized or placed into context. When data is organized, it becomes information. Information can be processed and used to draw generalized conclusions or knowledge.
  4. 4. 1.7 Methodology Used in Developing the Software Product Data Gathering : Conducting of 5 interview, involving of 30 personnel of the Barangay Hall, Dita to understand the roles, the procedures, issues, opportunities, and challenges of payroll process. VB orVisual Basic is a Programming tool that user to develop Windows or GUI(Graphical User Interface) applications. It means that rather than writing numerous line for code to describe the appearance and location for interface elements like C, C++, or Basic. User can simply drag and drop pre-built objects into the form window on computer screen. VB is a enhanced version of BASIC programming language(NASIC is Predecessor of VB)/ The main difference is that the VB can create windows programs by just Drag & Drop where as BASIC could only create DOS programs or work only in CUI (Command User Interface) 1.8 User’s Manual Public Class dbSelect Inherits System.Windows.Forms.Form Public Shared StartUp As dbSelect Private Sub btnNSM_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNSM.Click Dim Login As New Login
