QuickBooks 2013 to Tally Migration

I need my entire accounting history moved from QuickBooks 2013 Desktop into Tally Prime with absolute fidelity. The scope covers every financial transaction ever recorded, all customer and vendor master data, and the complete inventory ledger—as far back as the files go. I am not looking for any bespoke add-ons or custom modules in Tally; its out-of-the-box features are fine once the data lands correctly.

Here’s how I see the engagement:

• Extract, transform, and load every data set—financial, customer/vendor, inventory—into the matching structures in Tally Prime.
• Preserve account mappings, item codes, tax codes, and document references so that reports in Tally mirror what I can currently pull from QuickBooks.
• Run spot checks and provide a reconciliation report that proves opening balances, trial balance, and inventory valuation match exactly on both platforms for the same cut-off date.
• Deliver a brief hand-over note explaining any limitations or quirks found during migration and outlining the verification steps you performed.

Access to the QuickBooks company file, backup, and Tally licensing will be supplied immediately once we agree to proceed.
