One of the first questions I get when someone is seriously considering outsourcing payroll is: “okay, but how does it actually work?” Not in theory – in practice. What happens on day one? What does the monthly cycle look like? Who does what, and when?
It’s a fair question, and the honest answer is that it’s more straightforward than most people expect. The anxiety around switching usually comes from imagining complexity that isn’t there. So let me walk you through what managed payroll actually looks like from start to month, the way I’ve come to understand it at Paybooks.
Step one: onboarding your company onto the platform
Before any payroll runs, there’s a setup phase. This is where your managed payroll provider gets to know your company – and it matters more than people realise, because a badly done onboarding is usually where problems later in the relationship trace back to.
The onboarding typically starts with your employee master data. Every employee’s name, PAN, bank account, date of joining, designation, department, and location needs to be captured accurately. If you’ve been running payroll in-house, this data likely exists somewhere – in a spreadsheet, in your existing HRMS, or spread across a few different files. The provider’s team helps you consolidate and migrate it.
Then come the salary structures. How is each employee’s CTC broken down? What’s the basic, the HRA, the special allowance, the LTA, the medical reimbursement? Are there different structures for different grades or roles? All of this gets configured in the system so the payroll engine knows exactly how to compute each person’s monthly take-home.
Alongside this, your compliance registrations get mapped. PF establishment code, ESI code, Professional Tax registration numbers by state, TAN for TDS – the provider needs all of these to file correctly on your behalf. If any of these registrations are missing or pending, a good provider will flag that early rather than letting it become a problem at filing time.
A proper onboarding takes anywhere from two to four weeks. At Paybooks, we typically run a parallel check – one month where both your old process and the new one run side by side – so you can verify the outputs match before you fully hand over. It’s an extra step, but it’s the kind of thing that earns confidence before it’s needed.
The monthly payroll cycle: what actually happens each month
Once you’re live, managed payroll settles into a rhythm. The same cycle repeats every month, with your HR team doing far less than they used to and the provider’s team handling the execution. Here’s how it flows.
Inputs come in from your end
Around the same date each month – usually somewhere between the 20th and 25th – your HR or finance team sends the payroll inputs to the provider. This typically includes attendance data (who was present, who was on leave, who had loss of pay), any variable pay or bonuses for the month, new joiner details for anyone who joined mid-month, and details of any exits or final settlements due.
Most providers have a defined input template that makes this process clean and consistent. You fill in what’s changed, the provider handles everything else. If your HRMS is integrated with the payroll system – which many providers offer – some of this data flows automatically without anyone having to export and send a file.
The provider processes and shares the output for your approval
Once the inputs are in, the provider’s payroll team runs the calculations. They apply salary structures, compute statutory deductions – PF, ESI, PT, TDS – factor in the attendance, variable pay, and any mid-month changes, and produce the payroll output. This typically includes a salary register showing every employee’s gross, deductions, and net pay, a bank transfer file ready to be uploaded to your bank, and a compliance summary showing what needs to be deposited and filed for the month.
Before any of this reaches you, it goes through an internal check at the provider’s end – typically a first review by the team lead and a second review by the payroll manager. Once that’s cleared, you get a draft output. You’re not just trusting blindly – you get to check the numbers, flag anything that looks off, and ask for corrections if needed. Once you’re satisfied, the provider sends the final output, your bank statement and salary payment instructions, and your HR team formally signs off on the month.
Salaries go out, compliance gets filed
Once you approve the payroll, the bank transfer file goes to your finance team or directly to the bank, depending on how your process is set up. Salaries hit employee accounts on the agreed date. Payslips are generated and either sent directly to employees or made available on a self-service portal where they can log in and download them.
The compliance side runs in parallel. PF and ESI challans are generated and filed by the due dates – the 15th of the following month for PF, the 15th for ESI as well. Professional Tax is filed as per the state-specific schedule. TDS is deposited by the 7th of the following month. The provider tracks all of these deadlines as part of the service, and your HR team doesn’t need to maintain a separate compliance calendar.
Handling joiners, exits, and mid-month changes
Payroll is not just about the people who were there all month. Growing companies have a constant flow of joiners and exits, and each one adds a layer of calculation – pro-rated salary, PF and ESI on partial months, gratuity eligibility checks, full and final settlement computation.
Under managed payroll, all of this is handled by the provider. Your HR team shares the relevant details – joining date, last working day, leave encashment eligibility – and the provider does the rest. Full and final settlements, which are often a source of delays and disputes under in-house payroll because they require careful calculation across multiple components, get processed within the agreed SLA.
Year-end: the part everyone dreads
The financial year-end is where in-house payroll teams traditionally spend a significant amount of anxious time. Investment declarations need to be collected and verified, final TDS computations need to be done, Form 16s need to be generated for every employee, and annual PF and ESI returns need to be filed.
Under managed payroll, this is all part of the service. The provider manages the investment declaration cycle – collecting declarations from employees, factoring them into monthly TDS, and then reconciling at year-end. Form 16 Part A and Part B are generated and distributed. Annual returns are filed. Your HR team’s year-end payroll workload goes from several weeks of stress to reviewing and approving outputs that someone else prepared.
What your team actually does in this model
This is the part that surprises people most. Under managed payroll, your HR team doesn’t disappear from the payroll process – they just stop being the ones executing it. Their role shifts to providing accurate inputs, reviewing outputs, approving the payroll run, and handling the human side of payroll queries that come from employees.
That last part – employee queries – is worth noting. Employees will always have questions about their payslips, their TDS, their PF balance. Many managed payroll providers offer an employee self-service portal that answers a good chunk of these without HR needing to get involved. But for the questions that do come through, your HR team needs to know the payroll well enough to respond, which means staying engaged with the outputs even though they’re not producing them.
In practice, most HR Managers find that managed payroll takes their monthly payroll time from two or three days down to a few hours. That’s not a small shift. That’s time that goes back into the things HR is actually supposed to be doing.
