Frequently Asked Question

The Reference Time is the SDC Time of the fiscal invoice which is being referenced. It identifies the exact date and time when the previously issued fiscal invoice (that is being referenced) was issued.

The Reference Time is always optional information on an invoice. It can be used on any Refund or Copy transaction - to refer to the SDC Time of the original invoice that is being refunded or copied.

The purpose of using the Reference Time is for a SDC to determine which Tax rate group to use when creating Refund or Copy invoices. If the Reference Time is not submitted by a POS, the SDC uses the currently active tax rate group.

Example:

• A Normal Refund invoice is issued with a Reference Time 12/04/2021 22:22:34
• This means that the SDC Time of the Normal Sale invoice which is being refunded was also 12/04/2021 22:22:34
