A plant does not have a payroll problem in month one. It has an attendance problem that becomes a payroll problem on the thirtieth.
Rotating shifts, night allowance, overtime and a contract workforce that changes every week mean the input data is the hard part. The calculation is the easy part.
Get these five right
- Rosters that reflect reality - who was scheduled on which shift, including swaps.
- Attendance captured at the gate, not reconstructed from a register.
- Overtime derived from the roster, at the correct rate.
- Contract labour on the same system, so total labour cost is one number.
- Statutory deductions from the same run - PF, ESI, PT, tax declarations.
HR, GPS attendance, shifts, leave, payroll, tax declarations, onboarding, engagement, projects and timesheets — one employee record behind all of it.

Attendance in a biometric export, overtime in a supervisor’s notebook, contract labour in a contractor’s bill, and payroll in a spreadsheet that someone rebuilds every month. It works until the person who understands the spreadsheet takes leave.
How MizUp BMS handles it
MizUp BMS holds employee management, GPS attendance, shifts and rosters, leave and holidays, and payroll with tax and loans behind a single employee record. Overtime and allowances are derived from the roster and the attendance that is already in the system, so the payroll run is a calculation rather than a reconstruction.
Contract and permanent staff can be held with different types and cost centres, and access is controlled per module so a shift supervisor sees attendance without seeing salaries. Induction and safety training can run in MizUp EOS from the same employee record.
What it costs
From Rs 79 per employee per month. See BMS pricing.
Where to start
Put one month of rosters and gate attendance into the system before running payroll from it. The gaps you find are the gaps you were already paying for. Explore MizUp BMS.
Where plants usually go wrong
- Overtime from a supervisor’s notebook. It is the most disputed number in any plant, and the only fix is deriving it from the roster and the gate.
- Contract labour outside the system. If the contractor’s bill is the only record, the plant does not know its own labour cost.
- Rosters published on Friday for Monday. Almost every avoidable absence problem in a plant starts with a roster nobody saw in time.
- Shift swaps recorded informally. A swap agreed between two operators and never entered is a payroll dispute waiting for the thirtieth.
- Statutory deductions assembled separately. PF, ESI and PT calculated outside the payroll run is how a plant ends up with three versions of the same month.
- Attendance data that arrives too late to act on. Knowing on the fifth that a line ran short on the second is history, not management.
A realistic first thirty days
| Week | Focus | What good looks like |
|---|---|---|
| Week 1 | Employee master | Permanent and contract staff loaded with type, cost centre and shift pattern. |
| Week 2 | Rosters | Published two weeks ahead. Swaps entered in the system, not agreed verbally. |
| Week 3 | Gate attendance | Captured daily. Compare one week against the existing register before trusting it. |
| Week 4 | Parallel payroll | Run it alongside the current process once, reconcile, then cut over. |
A plant should never cut over payroll on the first run. One parallel cycle is the difference between a smooth transition and a shop-floor problem.
The numbers worth watching
| Metric | Why it matters | How to read it |
|---|---|---|
| Overtime as a share of rostered hours | Usually a rostering problem, not a discipline one | By line and by shift, monthly. |
| Absenteeism by shift | Night shifts behave differently and should be measured separately | Absent days divided by rostered days. |
| Contract labour cost per line | Often the largest invisible cost | Needs contract staff inside the same system. |
| Payroll disputes raised | The clearest measure of data quality | Should fall to near zero within two cycles. |
| Roster publication lead time | Predicts most of the above | Days between publishing and the shift starting. |
The data problem, not the calculation problem
Payroll software rarely fails at arithmetic. It fails because the inputs arrive late, in three formats, from people who were solving a different problem. A plant that fixes rostering and gate attendance finds payroll becomes uneventful without anyone touching the payroll module.
That is why the sequence above starts with the roster. It is the least exciting part of the system and the one that determines whether every downstream number is defensible.
There is a second benefit that plants notice within a quarter. When overtime is derived rather than negotiated, the monthly conversation between supervisors and accounts disappears, and both sides get their time back.
Contract labour is the last piece. Until it is inside the same system, the plant is managing a cost it cannot see.
How this fits with the rest of your stack
A manufacturing unit runs two businesses that rarely share data: the plant and the office. Labour cost sits in one, material cost and invoicing in the other.
On MizUp, BMS holds the employee record, the roster, gate attendance, leave and payroll with statutory deductions, and Finance covers purchases, job work challans, finished-goods invoices and GST reports. Both read the same organisation with the same access rules, so a cost centre means the same thing in both.
Induction and safety training can be delivered as courses in EOS against the same employee record, which matters for audits more than most plants expect.
Before you change anything, measure one month
The most useful thing a plant can do in its first month is not configure. It is compare. Run gate attendance alongside the existing register for four weeks and look at the difference, line by line and shift by shift.
The gap is almost always larger than expected, and it is rarely about dishonesty. It is late entries, swaps that were never written down, half-days recorded as full, and contract labour counted differently by two people. Each of those has a different fix, and none of them is visible in a monthly summary.
That four-week comparison also settles the internal argument before it starts. Supervisors who have seen their own line’s numbers tend to defend the new system rather than resist it, because the alternative is being blamed for a discrepancy they did not create.
Only after that comparison is payroll worth moving.

Frequently asked questions
What makes manufacturing payroll harder?
Rotating shifts, night allowances, overtime at statutory rates and a contract workforce that changes weekly. Each adds a rule that a generic payroll tool does not know about.
How should overtime be calculated?
From actual attendance against the rostered shift, at the rate your policy and law require - not from a supervisor’s note at month end.
Can it handle contract workers alongside permanent staff?
Yes. Keep them as employee records with a different type and cost centre, so the plant’s true labour cost is visible in one place.
Does GPS attendance make sense in a plant?
For gate-based staff, a fixed device or geofence is usually better. GPS matters for field and maintenance teams who are not at the plant.
What about statutory compliance?
PF, ESI, professional tax and tax declarations need to come out of the same payroll run rather than being assembled separately each month.
