Sage 100 to QBO Migration

I’m ready to retire Sage 100 Contractor and move everything into QuickBooks Online without losing a single cent of history. The scope is focused solely on financial transactions—no customer, vendor, or payroll records—so I need a specialist who knows both platforms inside out. Here’s exactly what must make the trip: • Invoices • Expense records • Bank transactions • Chart on accounts Both historical data and the current year’s activity have to land in QBO intact, reconciled, and aligned with the original reporting in Sage 100 Contractor. Acceptance criteria: 1. Opening balances in QuickBooks Online match Sage 100 Contractor to the penny. 2. Every invoice, expense, and bank transaction is searchable in QBO by original date and reference. 3. The chart on accounts structure remains identical, preserving account numbers and hierarchy. 4. A post-migration trial balance and two random month-end reconciliations show zero variance. If you have proven experience migrating data between these exact systems and can complete the work with minimal downtime, let’s talk.
