I see what's your point ... This is a standard task for transnational companies and 1C Enterprise provides all needed tools to complete the task.
Option No 1. You translate your applied solution (configuration).
What you need is to add another language in the applied solution (configuration) you purchased and add translations for each element in structure you need.
Please note, 1C:Translator will help you to make translation easier, but this is not a "language pack" to add another language by one click.
Depending how many objects you want to translate (everything from just these ones you need such as some documents, reports etc to the whole configuration), this would require from some man-hours to tens and hundreds man-hours ...
Translation which is done in this manner allows to assign different interface languages to different users, so you do not need to switch system language back and forth. For instance, you employees continue with Russian interface and you have Swedish or English.
If you do such translation, you basically modify your configuration. This also means that you will have some issues with scheduled updates and support which your supplier provides ...
Option No 2. External reports.
Another solution which might help you in this situation would be to make some external reports in English which will show you these figures you need (cash flow, sales, stock etc). This will be much easier and you will keep your original configuration with no changes. This means, no problem with the support, updates etc.
Should I call you tomorrow to discuss this closer?
Have a nice evening!
