Payroll outsourcing vs payroll software vs spreadsheets: which fits an Indian MSME?

There are three basic ways to run payroll in an Indian MSME: spreadsheets with a CA or consultant handling filings, payroll software operated by your own staff, or an outsourced payroll bureau that processes payroll from your inputs. Software usually has the lowest three-year cost once you pass roughly 15–20 employees and have someone to run it; a bureau suits businesses without payroll staff or with many sites and high churn; spreadsheets work only for very small, simple payrolls. Whichever you choose, the employer stays legally responsible for correct wages, deductions and deposits. The sums below are illustrative.

This guide is part of the best-fit selection method.

The three options compared

	Spreadsheet + CA	Software in-house	Outsourced bureau
Who calculates	Your staff, with formulas	The software, operated by your staff	The provider
Who files PF, ESI, PT, TDS	Your staff or the CA	Your staff using generated files	Usually the provider
Typical pricing	Staff time + professional fees	Per employee per month + setup + staff time	Per employee per month or per payslip + fees
Control and speed	High control, slow	High control, fast	Less control; depends on cut-offs
Key-person risk	Very high	Medium	Low internally, but provider dependence
Labour code changes	You must redesign formulas	Vendor updates the engine	Provider updates its process
Employee self-service	None	Usually included	Varies; sometimes via provider portal
Best for	Under about 10–15 staff, one state	15–500 staff with a payroll owner	No payroll staff, many sites, high churn

Three-year illustrative comparison for 40 employees

Option	Lines	Three-year total
Spreadsheet + CA	Staff 30 h/month × ₹400 × 36 = ₹4,32,000; CA filing support ₹5,000/month × 36 = ₹1,80,000	₹6,12,000
Software in-house	40 × ₹100 × 12 × 3 = ₹1,44,000; setup ₹40,000; staff 8 h/month × ₹400 × 36 = ₹1,15,200	₹2,99,200
Outsourced bureau	40 × ₹300 × 36 = ₹4,32,000; onboarding ₹15,000; internal 4 h/month × ₹400 × 36 = ₹57,600	₹5,04,600

All amounts are before GST and illustrative. The ranking flips with your assumptions: if you have no one able to run software, the "staff time" line for software is really the cost of hiring someone, and the bureau may win. If your payroll person costs ₹800 an hour, not ₹400, spreadsheets become far dearer. Put your own numbers into the payback calculator and the 3-year TCO example.

When outsourcing fits

No one in the business understands PF, ESI and TDS well enough to check results.
Many sites or states, with high joiner and leaver volumes.
You need confidentiality for senior salaries.
You prefer a predictable monthly fee and accept fixed input cut-offs.

What to insist on: a written scope (which returns, which states), a monthly cut-off and delivery calendar, your right to review the payroll register before bank upload, access to all filed returns and challans, a process for urgent off-cycle settlements within the two-working-day rule, data protection terms and full data return on exit.

When software in-house fits

You have an HR or accounts person who can own payroll.
Attendance, leave and shifts need to flow automatically into pay.
You want employee self-service, and journals posted to your accounting system.
You expect to grow; per-head software cost falls as headcount rises.

What to insist on: statutory updates included, support during payroll week, and a successful parallel run before go-live.

Hybrid options

Many MSMEs mix approaches:

Software plus a CA review: you run payroll in software; a CA reviews TDS quarterly and the year-end.
Software with managed payroll: some vendors offer an add-on where their team processes payroll in your software.
Bureau for contract labour, software for staff: shop-floor workers through a contractor, salaried staff in your own system. Remember your principal-employer duties to check the contractor's PF, ESI and wage payments.

Risks that cost money in every option

Risk	Typical cause	Control
Wrong PF wages	50% rule not applied, ceiling not updated	Monthly exception report, test cases
ESI dropped too early	Contribution-period rule ignored	Rule check at the period start
TDS short deduction	Regime choice or proofs not updated	Quarterly review of projections
Late full and final settlement	Approval delays	Off-cycle workflow, two-working-day target
Bank file errors	Manual edits	Locked files, maker-checker approval

Moving from one option to another

From spreadsheets to software, the main work is cleaning employee masters and setting up salary structures. From a bureau to software, get year-to-date data and filed returns back from the provider first; your contract should require this. From software to a bureau, export registers and history before the subscription ends. The payback guide shows how to judge whether a switch is worth it.

Frequently asked questions

Does outsourcing transfer legal responsibility?

No. The employer remains responsible under the labour codes and the Income-tax Act, 2025 for correct deductions and deposits.

Is a bureau cheaper for 20 employees?

Sometimes, if you would otherwise need to hire or train someone. Compare total cost, including your own time in both cases.

Can a CA run our payroll?

Many CA firms offer payroll processing. Treat it like any bureau: written scope, calendar and data terms.

Does GST apply to payroll outsourcing fees?

Yes, payroll services are generally taxed at 18% GST.
