Methods, computer-readable media, and apparatuses support data entry and aggregate work entries for an account. Different work codes are mapped to different categories for an account. Work entries are aggregated for the different categories in a report or in an invoice for the account. A worker may be mapped to client, which may further include a client region, when aggregating work entries to different categories for an account. A data structure is formed to include account information. The data structure can assume different structure types, including a data cube having three or more dimensions. A spreadsheet file may be linked to the data structure, and the contents a database may be synchronized to the spreadsheet file. The contents of the database may be categorized, analyzed, and aggregated, in which the contents are exported to provide a report on a worker and/or account.
