Card charges are imported into Nexonia after they have been posted to the statement by the bank. Depending on the merchant recording the charges, the day of the week, and other factors, this can take anywhere between one or two business days to one week.
Several factors typically account for the longer posting times. The day of the week when the charge is made can be factor as charges are typically not posted on the weekend. A charge made on a Friday may not show up until the next Monday or Tuesday. Sometimes when a charge is made offsite from a vendor's typical location (e.g.: they have a booth at a trade show), those charges are not reconciled at the end of the business day but rather at the end of the event.
