In MICE, it is possible to change the invoice date even after the invoice has been sent (this applies to both manual sending and sending to the client).
An invoice always remains a draft until it has been sent. A draft invoice does not yet have an invoice number or invoice date.
⚠️ Important: Changing the invoice date may cause accounting or tax issues. Always consult your accountant before changing the invoice date for a specific invoice.
Send manually / Send
With Manual sending, the invoice is not sent to the client, but it is still fully processed - meaning it gets both an invoice number and an invoice date, and the PDF version is downloaded.
With Sending, the invoice is sent to the client and fully processed.
In this case, it is strongly discouraged to change the invoice date, as it will cause discrepancies between your records and the client’s records.
💡 Note: If you use an accounting integration, manually sent invoices will also be eligible for synchronisation with your accounting system.
Changing the invoice date
Once the invoice has been (manually) sent, you can change the invoice date as follows:
Open the invoice.
Click “More” at the top of the invoice.
Select Edit invoice.
Change the invoice date and click Save. ✅
