How Green migrates your payroll.
Five steps, start to finish. Step 4, reconciliation, is what separates a real migration from uploading a CSV and hoping for the best.
- 1
Export your data
We tell you exactly what to pull.
A simple checklist of the exports and reports to run from your current provider. Most take under 15 minutes.
Employee details, pay rates, deductions, tax jurisdictions, year-to-date totals and benefit elections.
- 2
We normalize & validate everything
No spreadsheet cleanup on your side.
Our import engine maps your provider's columns to one model and recognizes formats we've seen before, including iSolved, ADP and Paychex.
Checks required fields, email, phone and state codes, numeric bounds, and duplicates.
- 3
Exceptions go to a person
Nothing is silently dropped.
A missing state code, an unusual deduction or an employee with no email is flagged for your Green rep to review with you.
Four exception types: missing, invalid format, out of range, duplicate.
- 4
Reconciliation before your first payroll
Discrepancies are resolved, not hand-waved.
We compare employee count, gross pay, deductions and net pay against your old system before anything runs.
The reconciliation report stays in your portal as a permanent record.
- 5
Go live with confidence
A specialist stays with you.
Once reconciliation is clean you run your first Green payroll, with your onboarding specialist on hand for the first 2 to 3 pay periods.
Your portal tracks every onboarding task, document and milestone.
The worries that keep owners from switching, answered.
“My employees will get paid wrong during the switch”
Record-level reconciliation catches discrepancies before the first payroll runs. Year-to-date totals, deductions and tax jurisdictions are checked against your old system.
“Tax filing will get messed up mid-year”
We file with your imported year-to-date data. A mid-year switch is standard, and the agencies see one continuous history, not a gap.
“It'll take months and drain my team's time”
Most migrations finish in 2 to 4 weeks. Your part is the export, with a checklist, and a few clarifying questions.
“I'll lose my reporting history”
Your old provider's records stay yours to download. Year-to-date data carries forward for tax and compliance continuity.
“Benefits enrollment will break”
Carrier Connect handles the carrier feeds, elections transfer with the migration, and open enrollment is timed so there's no gap in coverage.
