- A complete backup of your company file saved in at least two locations
- A list of all your bank accounts and login credentials
- A list of all connected third party apps and their login details
- Your payroll service information and employee records
- At least 3 days where business activity is slow
- Your new cloud accounting subscription ready and active
Phase 1 — Prepare Your Data Before Migration
Create Multiple Backups
File → Back Up Company → Create Local Backup → Save backup to: External USB hard drive, Second computer, Cloud storage such as Google Drive. Label each backup with today's date. Keep these permanently — do not delete after migration.
Reconcile All Accounts
Before migrating make sure every bank account and credit card is fully reconciled in your desktop software. Unreconciled accounts create serious problems after migration. Banking → Reconcile → Complete all pending reconciliations.
Clean Up Your Data
Remove duplicate customers and vendors. Merge accounts that should be combined. Clear out any test transactions. Fix any obvious data entry errors. Migration copies everything including mistakes — clean first.
Run Final Reports
Generate and save these reports before migrating: Balance Sheet as of today, Profit and Loss for current year, Accounts Receivable aging report, Accounts Payable aging report, Payroll summary for current year. Save as PDF — you will need these to verify migration accuracy.
Document All Custom Settings
Write down or screenshot: All custom reports you use regularly, Invoice and estimate templates, Memorized transactions, Chart of accounts structure, Class and location tracking setup. You will need to rebuild these after.
Phase 2 — Export Data From Desktop Software
Export Customer List
Reports → Customers & Receivables → Customer Contact List → Export → Save as Excel or CSV
Export Vendor List
Reports → Vendors & Payables → Vendor Contact List → Export → Save as Excel or CSV
Export Chart of Accounts
Lists → Chart of Accounts → Export → Save as Excel or CSV
Export Item List
Lists → Item List → Export → Save as Excel or CSV
Use Built-In Migration Tool
Most desktop accounting software has a built-in migration tool: Company → Export Company File to Online Version → Follow the wizard completely → Note the date and time of export
Phase 3 — Set Up Your New Cloud Account
Set Up Company Information
Log into your new cloud accounting software → Company Settings → Enter your: Business name and address, Tax identification number, Fiscal year start date, Industry type
Set Up Chart of Accounts
Import your exported chart of accounts or manually recreate it → Make sure account types match your original setup → Verify all balances are zero before importing transactions
Import Customer and Vendor Lists
Use the import function to upload your exported customer and vendor CSV files → Review for duplicates after import → Correct any formatting issues
Set Up Bank Feeds
Connect each bank account and credit card one at a time → You will need online banking credentials for each account → Download the last 90 days of transactions to start
Set Up Payroll
Enter your company payroll settings: Pay schedules, Tax information, Employee records, Year-to-date payroll history. This is the most complex step — take your time and verify each employee record carefully
Phase 4 — Verify Everything Transferred Correctly
Compare Opening Balances
Compare your new system opening balances against the reports you saved in Step 4 → Every account balance must match exactly → Do not proceed if any balance is different — find the discrepancy before continuing
Verify Customer Balances
Check accounts receivable total matches your pre-migration report → Spot check individual customer balances against your records
Verify Vendor Balances
Check accounts payable total matches your pre-migration report → Spot check individual vendor balances against your records
Test Run a Report
Generate a Balance Sheet and Profit and Loss in your new system → Compare against your pre-migration reports → Investigate any differences before going live
Run a Test Payroll
Before running your first real payroll: Run a test payroll for one employee → Verify tax calculations are correct → Check year-to-date amounts match → Only proceed with real payroll after test confirms accuracy
Phase 5 — Go Live Safely
Parallel Run First Week
For the first week run both your old desktop software and new cloud system simultaneously → Enter all transactions in both → Compare at end of each day → This catches any setup errors before they become serious
Disconnect Old Software
After one week of successful parallel running disconnect bank feeds from old desktop software → Do not uninstall old software yet → Keep it available for reference for at least 90 days
Train Your Team
Make sure everyone who uses the software has been trained on the new interface → Identify the most common tasks your team performs and practice those specifically → Appoint one person as internal expert for questions
Monitor First Month Closely
Review every transaction in your new system daily for the first month → Check bank reconciliation weekly → Verify payroll after every run → Report any discrepancies immediately
Mistakes To Avoid During Migration
Mistake 1: Migrating During Payroll Week
Always migrate during a slow period between payrolls — never during payroll processing week.
Mistake 2: Not Reconciling First
Migrating unreconciled accounts creates discrepancies that take months to untangle.
Mistake 3: Rushing Verification
Skipping the balance verification step means you may not discover errors until months later when they are much harder to fix.
Mistake 4: Deleting Old Software
Keep your old software and all backups for at least one year after migration for reference and audit purposes.
Mistake 5: Not Testing Payroll
Running real payroll without testing first risks paying employees incorrect amounts or filing incorrect payroll taxes.
