Lê Thu Trang

Trang graduated in 2020 and joined a service office that handled paperwork for household businesses: registrations, address changes, lump-sum tax. In those two years she walked most of the markets in the city centre and got to know how shops keep their accounts in a school exercise book with a pocket calculator.

She joined Sổ Sách Sáng in 2022. In six years of work, most of her clients have been fabric shops, eateries and phone stores.

Who she works with

Her clients are household businesses with revenue of VND 1 billion a year or more: a fabric stall in Bến Thành market, a bánh mì shop in Đa Kao, two phone stores on Cách Mạng Tháng Tám street. Since late 2025 she has led our work moving households from lump-sum tax to self-declaration: choosing the type of e-invoice, opening the revenue book and filing the first quarter.

Trang works in Vietnamese. If you write to her in English, Quân or Hạnh will help.

A habit

In the first month with each household she spends a morning at the shop, watching how the owner sells and writes things down. Then she sets up a Zalo album for each month, and the owner just photographs supplier invoices into it. No software to learn, no one to remember to send things to.

Chị Lan at Bến Thành market says that every time a tax notice used to arrive she got three calls from three different people. Now it is only Trang, and Trang calls first. Trang keeps a running revenue total for each household, so when a shop is about to cross a threshold she knows a quarter ahead.

What she is learning

She follows every change to the eTax Mobile app, because many owners file on their phones and call her when a screen looks different. She is also studying Circular 152/2025/TT-BTC on household bookkeeping, and putting together a sample revenue book filled in with one week of sales to give to new clients.
