You can now send him a copy of your budget by loading your budget into your program;   select file;   select archive;  select Pack Up.  This will create a zipped version of your budget.  All forty or so files which represent your budget (Example, budget 'ABCD' ) will become a single very compact file called: ABCD.ZIP ( about 200K for a typical budget).   You can E-mail this file to the producer in London.

In London, the producer selects File;  selects Archive, and selects Unpack.   This will directly unpack the ABCD.ZIP file you sent,. and enable him to view and edit your budget.

Export/Import data to spread sheets, databases, accounting systems. This feature allows you to export the chart budget data into a spread sheet where you could then create a cash flow model. You could also export budget data down to the detail level and do analysis over many budgets.

Cross budget comparisons.
Both programs allow you to compare a budget and some previous version of itself, i.e., a five week and a six week budget. Studio also allows you to compare two budgets prepared separately, by allowing you to import one budget into the compare mode of the other.

Powerful and targeted data manipulation:
the MODIFY COMMAND. This Studio only command allows you to search the budget for a class of lines (e.g., all IATSE CREW) and selectively apply a change to a specific column (e.g., the hourly pay rate increased by 6% when a contract changes).

Managing a complex template.
Since TBW allows you to create a budget with up to 400 codes, the studio edition provides a number of code management tools: sort codes, pack codes, validate codes; and perhaps the most useful: populate codes, an option which automatically puts computed codes into the budget form for you.
