Style guide changes

Where I work, we recently agreed a few minor changes to our style guide. We're now using:

• cashflow instead of the Oxford English Dictionary's 'cash flow'

• seatbelt instead of the OED's 'seat belt' or our previous 'seat-belt'

• T-shirt instead of our previous 'teeshirt'

So we're moving away from the OED when it comes to compound nouns. At least we're now in agreement with the dictionary over 'T-shirt'.
