Accounting reports have a significant amount of data. It is not only the first level of information that is compiled; there are multiple levels of information. A year-to-date report for the end of the year can take in excess of fifteen minutes, depending on the size of the practice. If you are using a slow computer or have a slow internet connection, it can take even longer. If the report takes too long to compile, the system will automatically time itself out. If you have difficulty running the end of year report, you can break the report up into date ranges of smaller increments, try a different computer, or run the report at a time of the day when other computers in the office are not being used.
