I'm creating a Custom Field in CRM to map to the Payment Terms field of Zoho Books.

In addition to the "Due on Receipt" terms, Zoho has recently added some clever "Due end of the month" and "Due end of next month" options in Books, so which data data type should I create the field in CRM with, to be able to sync the data correctly. Would a pick-list with exact copies of the text be sufficient?

By default I'd like the terms to be "Due on Receipt".

Thanks,

James
