Payroll software for factory workers in plastics and packaging

Pay machine operators on the A and B shifts, helpers at the grinder and the packing team from one attendance record, and take back the advances given before the holidays without a diary.

In short

SimpleERP is payroll software for factory workers in plastics and packaging units. Operators on day and night shifts are paid monthly from attendance, with tax and social security deductions on the payslip, and advances recovered month by month.

A payroll day at Sierra Polymers

Sierra Polymers runs its machines on two twelve-hour shifts, A from 8 in the morning and B from 8 at night. Twenty-eight operators and helpers rotate between them, many from villages in Veracruz and Oaxaca, and several live in rooms the company rents near the industrial park. The A shift feeds HDPE and PP granules with masterbatch into the injection moulding and blow moulding lines for jerry cans and closures, the B shift runs regrind and packs cartons, and both are paid the same shift rate.

Before Holy Week and again before Christmas, half the floor takes an advance to travel home. The supervisor has to know who came back on time, the payroll has to know who owes what, and the owner wants salaries out on time.

How do I set up day and night shifts with rotating weekly offs?

Create the A shift and the B shift with their hours and grace minutes, and assign each operator to one. The supervisor marks the floor present in one tap at shift change, then fixes the absentees.

  • Late marks follow each shift's grace minutes the same way for everyone.
  • Weekly offs per employee, so the rotation does not show up as absence.
  • Unmarked days are flagged in the run, so a missed mark at shift change is caught.

Which components go on a machine operator's payslip?

Each operator has a salary structure. Income tax and social security are deductions you set on each structure from the rules that apply to you; SimpleERP does not read government tables.

  • Room rent for company quarters can be its own deduction component.
  • Overtime past the shift is added as an earnings line on the draft payslip.
  • Employer social security as its own component, posted on approval.

What does an operator's month come to?

Javier runs a blow moulding machine on the B shift. His Basic is $900 and shift allowance $90, a gross of $990. Income tax of $45, social security at 2.5% of gross, $24.75, a room rent deduction of $40 and an advance instalment of $50 leave a net of $830.25.

  • Absent days after the holiday trip become loss of pay automatically.
  • The advance stops being deducted once it is repaid.
  • Payslips print on A4 for those without a self-service login on their phone.

Honest limits

What SimpleERP does not do yet

  • Income tax withholding is not computed from government tables; you set the deduction per employee
  • Social security, pension and end-of-service amounts are components you set, not statutory calculations
  • No biometric device integration: attendance is marked on the phone or entered by HR
  • No overtime worked out from shift hours; enter the overtime amount on the draft payslip
  • No pay per piece moulded; operators are paid a monthly salary

Getting started

  1. Sign up with your email

    Name, email and a password. No card for the seven-day trial.

    Pick your country and, if you are registered, type your tax number. Accounts, tax rates, units, roles and numbering are seeded for that country.

  3. Add your people

    Add operators, helpers and packers with their shift, weekly off and salary structure, including room rent only where it applies.

  4. Run the first payroll

    Attendance and leave feed the run; payslips post to the books and staff see them on their phones.

FAQ

Questions, answered

My operators work twelve-hour shifts. How is the extra time paid?

SimpleERP does not calculate overtime from shift hours. Work out the overtime as you do today, then add it as an earnings line on each operator's draft payslip before approving the run. It posts to salary expense with the rest of the pay.

Some workers leave for their village and come back after three weeks. What happens to their pay?

The days they were marked absent become loss of pay in that month's run, pro-rated across every component. If they took leave you approved as paid, those days are paid. Nothing has to be worked out by hand.

Can a helper who left mid-month be paid his dues?

Yes. Mark him absent for the days after he left, and the run treats them as loss of pay, so he is paid for the days he worked. Any advance balance he still owes is shown on the advances page so you can settle it with him.

How much tax and social security do I deduct?

That depends on your country and each worker's pay, and the rates change, so check the current ones with your payroll consultant. In SimpleERP you set each amount or percentage on the structure and it is posted to its payable account.
