Peachtree to QuickBooks Migration in 2025: Zero‑Downtime Checklist by E‑Tech CA
Plan a Zero-Downtime Migration
Moving from Peachtree (Sage 50) to QuickBooks in 2025 should not interrupt billing, payroll, or reconciliations. The key is a staged approach: freeze non-critical edits, run a clean backup, perform a production-grade test conversion, validate with side-by-side reports, and only then execute a short cutover window. E‑Tech CA’s checklist below is designed to keep your team transacting while your accounting moves safely.
Choose Your QuickBooks Destination
QuickBooks Desktop vs Online
· QuickBooks Desktop: Best for advanced inventory, heavy job costing, and large data files. Strong performance on local/hosted servers.
· QuickBooks Online: Anytime, anywhere access, native app ecosystem, and easier collaboration. Ideal if you want reduced IT overhead.
Scope Your Data Depth
· Full historical: Customers, vendors, chart of accounts, items, invoices, bills, payments, credits, journal entries, and inventory transactions.
· Opening balance start: Bring accurate opening balances as of a cutover date, plus open transactions. Faster and leaner.
Pre-Migration Readiness Checks
Clean Your Peachtree File
· Reconcile bank and credit card accounts up to the latest statement.
· Post all batches, close open periods you do not plan to edit, and clear duplicate masters.
· Resolve negative inventory and mismatched item costs.
· Run data verification/repair utilities and archive a final, read-only backup.
Align Fiscal Settings and Lists
· Confirm fiscal year/month setup and tax basis (cash vs accrual).
· Standardize names: customer, vendor, item, class/job names, and inactive flags.
· Map sales tax codes and rates you still use in 2025; retire obsolete ones.
Zero‑Downtime Framework by E‑Tech CA
Parallel Run Strategy
· Freeze edits to prior periods. Allow new transactions in the current period only.
· Take a gold backup of Peachtree, then enable read-only access for the team during conversion.
· Continue daily operations in Peachtree while the conversion and validation happen in a separate environment.
Delta Capture Plan
· Define your cutover date and a short blackout window (often an evening or weekend).
· Log all new transactions created after the gold backup.
· Prepare import sheets for deltas (invoices, receipts, bills, payments) to inject into QuickBooks at go-live.
Field‑By‑Field Mapping Essentials
Masters and Lists
· Customers/Vendors: Names, contacts, terms, tax settings, currency, opening balances.
· Items: Service, non-inventory, inventory, and assemblies; units of measure; income/COGS/asset accounts.
· Chart of Accounts: Exact account names, numbers, types, and sub-account hierarchy.
Transactions and Balances
· AR/AP: Open invoices, bills, credits, and unapplied payments.
· Inventory: Quantities and costs as of cutover; confirm item valuation method alignment.
· General Ledger: Trial balance as of cutover; retain historical detail if doing a full transaction migration.
Compliance and Local Tax
· Sales tax: Map to QuickBooks tax centers (e.g., GST/HST/PST or VAT/GST). Validate rates and agency liabilities.
· Payroll: Bring employee profiles and year-to-date figures to ensure correct remittances and slips/forms.
Test Conversion and Verification
Dry Run Validation
· Reports to match within tolerance:
o Trial Balance as of cutover date.
o AR Aging and AP Aging detail.
o Inventory Valuation Summary and stock counts.
o Sales tax payable and agency summaries.
· Spot-check customers, vendors, and items for correct terms, taxability, and classes/jobs.
User Acceptance Testing
· Enter a sample invoice, bill, receipt, and payment.
· Run a bank reconciliation workflow with test data.
· Confirm custom fields and templates map to your operational needs.
Cutover Day Playbook
Finalize in Peachtree
· Stop new entries at the agreed cutoff time.
· Export the delta list of transactions since the test conversion.
· Take a final backup and lock the file read-only.
Go‑Live in QuickBooks
· Load the validated conversion file.
· Import deltas (same-day invoices, receipts, bills, payments).
· Re-run the four-key reports (Trial Balance, AR Aging, AP Aging, Inventory Valuation) and compare.
· Connect bank feeds, set user roles, and enable integrations (payments, payroll, apps).
Post‑Migration Audit and Optimization
First-Week Checks
· Reconcile bank and credit card accounts through the latest statements.
· Verify sales tax calculations on new transactions and agency balances.
· Confirm item costing on new POs, bills, and builds if you use inventory or assemblies.
Hardening and Training
· Lock prior periods and enable closing passwords.
· Document the new month-end checklist in QuickBooks.
· Train users on new workflows: receiving, billing, payments, recurring transactions, and reports.
Common Pitfalls to Avoid
· Migrating unnecessary history that bloats performance. If detail is not required for audits, prefer opening balances plus open transactions.
· Breaking item links by renaming items post-migration. Freeze structural edits until after your first close.
· Misaligned sales tax codes leading to incorrect filings. Test a full tax cycle before your next return.
· Ignoring user permissions. Set least-privilege roles on day one.
· Skipping a dry run. The test conversion is where you find mapping issues, not during go-live.

Quick FAQ
How long does a typical migration take?
A standard small-to-mid file completes in one to three business days including validation, plus a brief cutover window.
Will I lose my audit trail?
QuickBooks houses its own audit trail. Keep archival PDFs and exports from Peachtree for historical reference and compliance.
Can I switch mid-quarter?
Yes. Use a clean cutover date, bring accurate YTD figures, and reconcile immediately after go-live.
