Fixed vs Per-Employee Payroll Pricing: Which Costs Less?
Seasonal hiring, a new branch, a growth year: each one moves your software bill under one pricing model and leaves it untouched under the other. Plus six things to ask any vendor before you sign.

Payroll software in India is sold on two pricing models. The difference shows up on the invoice every month rather than in the feature list. Attendo (formerly Petpooja Payroll) charges a flat annual fee. Most of the category charges per employee per month.
This guide sets out how the two models behave, what changes as a team grows past 100 people, and which one suits which kind of business.
Key Takeaways
- A flat fee usually works out better when headcount moves during the year, because growth costs nothing extra on the software line
- Per-employee billing has the lower entry point if the team is small and likely to stay small
- Attendo runs on the flat model, with the attendance device, installation, support and every software feature inside one yearly fee
- The gap widens with size: on per-employee billing the bill keeps climbing, on a flat fee it does not move
The Two Pricing Models in Payroll Software
Both models are common in India. The difference is not the software you get, but how the bill behaves when your team size changes.
1. Flat Fee Pricing
The business pays one fee for the software, and the number of employees does not change it. Attendo works this way: a flat annual software fee, with no per-employee charges and no tier-based feature unlocking. Unlimited branches, departments and designations are included.
What works well:
- The bill is known in advance, which makes budgeting straightforward.
- Hiring does not trigger a price change, so seasonal peaks cost nothing extra.
- One invoice to reconcile rather than a headcount reconciliation each cycle.
- Nobody needs to time an employee exit around the billing cycle.
What this means as you grow: the fee is set once and then stops mattering. The same amount covers ten people or four hundred, so every person you hire after that costs nothing more on the software line, and the device, installation, support and every feature are already inside it. A team under ten with no plans to grow may find the entry point steep, and per-employee billing will start cheaper for them. For a business that is hiring, that is the point: the flat fee stops climbing, and per-employee billing does not.
2. Per-Employee Pricing
The vendor charges for each employee processed in the payroll cycle, usually per employee per month. This is the norm across the HR software category, and it is what most quotes in the market are built on. The Darwinbox comparison works through what that looks like against a flat fee.
What works well:
- The entry cost is low for a small team, so it is easy to start.
- A business that shrinks pays less the following cycle.
The honest trade-off:
- The bill moves every time the team does, which complicates budgeting.
- Growth is charged twice: once in salary and again in software.
- Seasonal staff carry a software cost for the months they are on the books.
- Headcount has to be tracked and reconciled against the invoice each cycle.
What Changes at 100 Employees
Neither model is cheaper in the abstract, because the rate decides that. What can be compared is the shape of the two bills as a business grows.
| What happens during the year | Flat fee | Per-employee billing |
| Team grows from 60 to 100 | No change | The bill rises with every hire |
| 20 seasonal staff join for three months | No change | Those three months cost more |
| A second branch opens | No change, branches are unlimited | More employees on the bill |
| Ten people leave in a quiet quarter | No change | The bill falls the next cycle |
| Budgeting for next year | One known number | Depends on the hiring plan |
Take a garment manufacturing unit in Surat running 100 staff that adds 20 tailors for the October to December wedding season (an example). On a flat fee those three months cost nothing extra. On per-employee billing they carry a software cost for as long as the tailors are on the books. A hotel in Jaipur staffing up for the wedding season, or a coaching institute in Indore hiring extra faculty for the exam months, meet the same arithmetic (both examples).
Package prices are not listed here because they change. The Attendo team confirms the current one on a call, along with which device suits the site.
What You Get with Attendo
The pricing model is only half the question. What sits inside the fee is the other half, and with Attendo that is the full workday rather than payroll alone:
- Attendance through fingerprint, NFC card, face recognition, an on-screen passcode, or a mobile punch with photo and geofence.
- Shifts and rosters covering 9 to 5, rotating, overnight and 24-hour timings.
- Leaves, holidays and multi-level approvals.
- Payroll on monthly, daily, weekly and hourly cycles inside one organisation.
- Settlements for loans, advances and arrears, deducted inside the salary run.
- Compliance for PF, ESIC, Professional Tax, TDS and LWF.
- An attendance device included with every package, with a lifetime warranty and on-site installation.
The full feature list goes deeper on each of these. The Employee App runs in 11 Indian languages, and support is 24×7×365, including on salary-processing days. More than 40,000 businesses use Attendo, with manufacturing and corporate offices the two largest groups.
Which Model Fits Your Business?
The answer usually follows from how much your headcount moves during the year.
| Your situation | Flat fee suits you when | Per-employee suits you when |
| Headcount | It moves during the year, or you plan to grow | It is small and likely to stay small |
| Budgeting | You need one number you can commit to | You can absorb a bill that moves monthly |
| Seasonal staff | You hire for peaks and release afterwards | Your team size barely changes |
| Multiple branches | You run several and want them all included | You operate from one site |
| Admin time | You would rather not reconcile headcount each cycle | You already track headcount closely |
The short version: a business whose team size moves is usually better served by a flat fee, because the cost of growth is already paid for. A small team that will stay small may find per-employee cheaper at the entry point.
How to Work Out Which One You Need
Six things to check before you sign anything, whichever vendor you are talking to.
- Write down your headcount today, and your realistic headcount in twelve months.
- Add any seasonal peak, and how many months it lasts. The attrition rate calculator helps if you are unsure how much your headcount actually moves.
- Ask each vendor for a written quote that separates the software fee, the hardware, the installation and any one-off implementation charge.
- Check what happens to the bill when someone joins or leaves mid-cycle.
- Confirm whether extra branches, extra devices or extra features cost more.
- Run your own numbers with the salary per day calculator to size the payroll the software has to handle.
Conclusion
Fixed and per-employee are the two ways payroll software is sold in India. The right one depends on whether your team size is stable or moving. A flat fee buys predictability and makes growth free on the software line. Per-employee billing keeps the entry cost low and charges you as you grow.
Attendo is built on the flat model, with the attendance device, installation, support and every software feature inside one annual fee. If your headcount moves during the year, that is exactly the case the flat model is built for.
