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.

Hi, I can help migrate your financial transaction history from Sage 100 Contractor to QuickBooks Online with accuracy as the main priority. I understand this is not just a basic import — invoices, expenses, bank transactions, and the chart of accounts must move over cleanly, with original dates, references, balances, account numbers, and hierarchy preserved. My process will be: First, I’ll review the Sage export structure and map the chart of accounts exactly to QBO. Then I’ll prepare and clean the transaction data for import, including invoices, expenses, and bank activity. After migration, I’ll verify opening balances, run a post-migration trial balance, and compare selected month-end reconciliations against Sage to confirm zero variance. Small hint: I’ll keep a migration checklist and reconciliation sheet so every imported transaction can be traced back to Sage by date, reference, and account. I’m detail-focused and understand that financial history must match to the penny before the project is considered complete. Best regards, Md. Shahadat Hossain
