How Will They Repeat?
When a repeat invoice date is reached, during the move from Cash Book to Platform, a list of invoice requiring repeat will appear.
Select the options and create the invoices. They will still be open after the repeat so you could edit if desired. Close them in the normal fashion.
The next invoice repeat date will automatically be set for you.
