Original Receipts required?

I am fairly new to this calling so coming here for advice.

I feel pretty cluttered with the copy of the original receipts in our filing system. Is it acceptable to file copies of receipts instead of the original receipts?

Thanks

The general requirement is indeed for original receipts, and the audit form does ask the auditor to verify that original receipts are generally used. Exceptions are allowed, but they should be exceptions, not the rule. See the thread Audit question on expense documentation: what does "original" mean? for more information.
