QuickBooks Data Migration (13yrs)

I need my entire QuickBooks Online Advanced file moved into a new QuickBooks Global account. The scope is very specific: about 15,000 transactions covering roughly thirteen years must come across intact, together with every attachment linked to those transactions. Attachments go back only two years only. I do not need inventory lists, sales-tax setups, or other tax-related data migrated—only the historical transactions and their supporting documents.

A clean, verifiable transfer is crucial. After the migration I should be able to open the Global company, pull any report back to 2013. The recent transactions from 2024 should show the attachments. Chart-of-accounts integrity must stay intact.

Timeline: I’m aiming to have this wrapped up within the next four weeks, so please factor in time for a post-migration review and any touch-ups we might uncover.

Deliverables
• Fully migrated new QuickBooks Global file with transactions and all attachments
• Side-by-side reconciliation report proving totals match between source and target
• Brief hand-off call or written summary explaining the steps taken so I can replicate the process if ever needed

If you regularly work with QuickBooks data tools—Transaction Pro, Dataswitcher, SaasAnt, or direct API scripting—and can guarantee accuracy, I’d love to hear how you’ll tackle this.
