Comprehensive Accounting Services Needed

As a busy company dealing with more than 100 transactions monthly, we're requiring professional assistance with our bookkeeping tasks. These tasks include invoicing and billing, bank reconciliation, and payroll processing. The ideal freelancer for this project should be proficient in popular accounting software—although, we are flexible since we're yet to choose our primary software. Experience in managing high volume transactions is a must, alongside excellent accuracy in data management. Proficiency in QuickBooks, Xero, or Sage would be a highly admired asset.
