Job Description

A part of my job involves typical secretarial duties which include handling of facsmiles, emails and letters. I also have to prepare reports, issue internal notices, handle other general documents and greet guests.

Another part about my job is about financial matters. I have to manage the budget and bookeeping ledgers.

The third area of my duty is regarding office administration. To fulfill the job requirement, I have to manage matters concerning business trips (or outdoor duties) by all staff**. Besides, I also place orders for office supplies.

Finally, I also assume the human resources (or marketing) function by placing recruitment (or promotional) advertisements.

Note:
1) I suggest that you categorise your duties to make it sound more systemic.

2) I suggest that you elaborate more on some areas,
e.g. greeting guests - say if you not just say hi & serve tea/coffee, and you actually have more interaction with them, like escorting them around your office or HK, even involved in biz negotiations, due to the wider scope of skills required, it's worthwhile mentioning in greater details.
Also about the biz trips / outdoor duties of other staff, you could elaborate more what exactly you mean - is it about itinerary planning & reservation of airtickets? Or is it about plainning of rostas of office assistants / other special staff? - these may be useful information to the person who would peruse your job description.

3) Tasks as photocopying doesn't need to be mentioned bec it is understood that it is generally part of every job, so quite meaningless to cover.

4) I don't agree with the 1st ans that job description should be generalized into a few words. Instead, I think it should be detailed & specific.

If i my duty is secretary, in charge to handle daily fax, email, letter, photo, do documentaries,report and publish company notice, photo cope, manage normal company expenditure, manage staffs out going events, to order equipments what company needs, advertisment and customer services.

office administration = fax, email, letter, photos, documentaries, report, 公司通告, 影印, 管理各員工出勤事務
bookkeeping and accounting = 管理一般財政收支
Purchasing = 訂購公司所需用品
Advertising = 出廣告
Customer services = 同埋招呼客人

No need to list out all the tasks details as it is understood.

I hold the position of secretary for my company. My job duties include handling day-to-day office administration, accounting and bookkeeping, purchasing, advertising and providing customer services support.
