Moving HR off spreadsheets and into an HRMS

01

Inventory every spreadsheet before you plan anything

Ask every person who touches HR data to list the files they keep. Not the official ones, all of them. The leave tracker a manager maintains for her team, the list of laptop serial numbers, the sheet that tracks who has submitted investment proofs. Each one is either data that must move, a process the new system must replace, or something that can stop.

For each file, note who owns it, who reads it, how often it changes and what decision depends on it. That list becomes your migration scope, and it usually reveals at least one process nobody in management knew existed.

02

Sequence the switch around payroll

Payroll is the module with a hard monthly deadline and statutory consequences, so it sets the calendar. Everything else either feeds payroll or does not, and that determines its place in the order.

1. 1Employee master: every other module refers to it
2. 2Salary structures and statutory registrations: payroll cannot compute without them
3. 3Leave balances and the holiday calendar: they decide paid days
4. 4Attendance capture: where loss-of-pay and overtime come from
5. 5Payroll, with a parallel month against the old process
6. 6Self-service for employees and approvals for managers
7. 7Performance, onboarding workflows and documents, once the monthly cycle is stable

Watch for itResist going live with everything at once to save a month. If the first payroll run disagrees with the old one, you want as few new moving parts as possible to search through.

03

Decide what history to bring across

You do not need to migrate every spreadsheet row since the company was founded. You need what the new system must act on and what you may be asked to produce.

Bring across current employee records, opening leave balances, current salary structures and, for a mid-year switch, year-to-date payroll figures. Archive the rest in a read-only, dated location with a clear owner, so the history is retrievable without pretending it lives in the new system.

04

Clean the data once, at the boundary

Migration is the one moment when every record passes through a single point, which makes it the cheapest moment to fix it. Duplicate employees, inconsistent department names, missing statutory identifiers and joining dates that differ between files all have to be resolved before load, not after.

Decide who has authority to resolve a conflict. When the leave tracker and the payroll sheet disagree on a joining date, someone must decide which is correct and record why. Without that authority the cleanup stalls on every disputed record.

05

Bring managers and employees across with a plan

The system replaces the spreadsheets only when people stop sending requests by chat and email. Announce a date after which leave is applied for only in the system, and hold to it. A manager who keeps approving on chat keeps the old process alive for their whole team.

Show managers the two or three things they will do every week, not the full product. Show employees how to apply for leave and download a payslip. Everything else can be learned when it is needed.

06

Retire the spreadsheets, visibly

The most common failure in a spreadsheet migration is that the spreadsheets survive. Someone keeps updating the old salary sheet just in case, and within six months there are two sources of truth again.

After the first clean payroll close, move each old file to the archive, make it read-only and tell everyone it has happened. If a report still depends on a spreadsheet, build it in the new system or write down why it cannot be.
