[General] I'm learning how to issue invoices

[Silverobama]

My student Nina told me recently she'd been up to something. She's cashier so part of her job is to go to tax bureau (a tax office perhaps) and follow the steps there to get invoice done and then to issue invoice. Since I'm not an expert in her field. I don't know how to say that. But she wants to speak English every day so she asked me how to express that idea. I then told her maybe she can simply say "I'm learning how to issue invoices" is okay.

Is the italic sentence natural when the context is clear (people know that she's a cashier)?

Note my corrections above. You really need to work on your use of articles. You omitted four obligatory articles. Your italic sentence is OK as long as the speaker understands what that entails.

Don't say she was "up to something". That has a negative connotation and usually suggests that someone was doing something naughty or even illegal!
