Need some help with some phrases please!

I work in an accounting department with the sweetest woman ever however she doesn’t speak much English. I do a lot of filing and sending emails in English to vendors or clients for her. I want to learn some phrases just because I can see when she’s busy and working, trying to find the words in English are frustrating. So it would be nice to learn some terminology.

Mostly I want to learn to respond “sure” to whenever she asks me to do something, or “is this to file”. Also maybe “Yes I have that”?
