Most companies don’t switch payroll software because the old system broke. They switch because it’s a spreadsheet held together by one person’s formulas, or a tool that never added Bangladesh specific compliance. The software isn’t the hard part. The actual risk is the migration itself, because a botched cutover means someone doesn’t get paid correctly, and that’s not a bug report, it’s a trust problem.
Why mid-cycle switches go wrong
The single most common mistake is trying to switch payroll systems partway through a pay period. Half the period’s attendance and deductions live in the old system, half need to go into the new one, and reconciling that split manually is exactly the kind of error prone work you were trying to get away from. Always time the cutover to the start of a new pay period, the day after the last payslip closes in the old system, not before.
What actually needs to migrate
It’s not just employee records. A payroll switch that only moves names and salaries, without historical data, creates problems the first time someone needs a past payslip or a year to date tax figure.
At minimum, plan for:
- Employee master data: names, designations, joining dates, bank or mobile wallet details for disbursement
- Historical payslips: at least the current tax year, so employees can still access past pay records
- Year to date figures: tax withheld so far this year, provident fund contributions, any loan or advance balances being recovered in installments
- Leave and attendance balances: carried over leave days and any pending regularizations that affect the next pay run
Bulk CSV import is the standard way to move this kind of historical data into a new system without re-entering it by hand. It’s worth confirming any platform you’re evaluating actually supports it before you commit, rather than finding out during the migration.
Run parallel before you cut over
Don’t trust a new payroll system with a live pay run on day one. Run one full pay cycle in parallel: the old system produces the official payslips, the new system runs the same inputs alongside it, and you compare the outputs line by line. Differences at this stage are cheap to catch. The same differences discovered after the new system is the only record are expensive, both in correction effort and in employee trust.
This is exactly what a trial period with no payment details required is for. It lets you run that parallel cycle and confirm the numbers match before any billing or commitment starts, instead of migrating live data into a paid system you haven’t verified yet.
After cutover, what to keep
Once the new system is confirmed correct and live, don’t delete the old system’s records right away. Keep read only access to historical data for at least one full tax year, since audits and employee queries about past pay don’t stop the day you switch.
Utso’s payroll software runs on a database isolated per company with CSV import for historical data and a 2 month free trial with no payment details required, so the parallel run and verification phase of a switch doesn’t require paying for a system you’re still validating.
One more thing
This is a general migration framework, not a substitute for planning specific to your current system’s export format or your company’s pay structure. Confirm what your existing provider actually allows you to export before committing to a cutover date.
