Hi it is possible on quickbooks to run a report of all supplier credits posted to the suppliers ledger for a given period?

Hello paul40,

Welcome to the Community - thank you for your question!

You can run a Transaction List by Supplier report. You can customise this by selecting Customse in the top right hand corner. Under this menu, select Filter and Supplier Credit under transaction type. You can then alter the date range, and filter by a specific supplier if needed.

Thanks,

Talia
