QuickBooks Online Expert Needed – Data Cleanup (11k+ Entries)

Project Overview:

I have just migrated 11,000+ entries from Excel into QuickBooks Online. The data is currently "categorized"—thousands of transactions are repeating from the same vendors/customers but are not categorized or assigned to the correct Chart of Accounts. I need a QBO expert to perform a massive cleanup, categorization, and reconciliation.

Scope of Work:
Batch Categorization: Use QBO Accountant tools or Bank Rules to categorize 11,000+ transactions by vendor/customer.
Chart of Accounts Cleanup: Map imported Excel data to the correct QBO accounts.
Duplicate Management: Identify and merge duplicate vendor/customer profiles created during the import.
Data Validation: Ensure the final Profit & Loss and Balance Sheet reflect the original Excel data accurately.
Efficiency: Use batch reclassification tools (SaaSAnt, Transaction Pro, or QBO Accountant) to avoid manual entry.

Requirements:
MUST have extensive experience with QuickBooks Online (Advanced or Accountant versions).
MUST be proficient in "Batch Reclassification" and bulk data management.
Proven experience with large-scale Excel-to-QBO migrations.
Attention to detail is critical; I cannot have "Uncategorized Expenses" left over.

To Apply:
Please start your proposal with the word "CLEANUP" so I know you read the full post. Briefly describe how you would handle 11,000 entries efficiently without doing them one by one.
