Having worked with Susan Stoll from “STS” for the past decade, I can honestly say she has been the most efficient, knowledgeable and supportive bookkeeper & accountant that AJA Trading has had the pleasure of working with. Susan has always offered flexibility and a willingness to work in a way that suited my businesses, and myself all the while having the tenacity to firmly and effectively deal with any issues that could arise.

Susan has a knack for explaining taxation issues in a succinct and concise way making her so much more approachable. Her business acumen is second to none leaving me with piece of mind knowing my: Accounts, Bank Statements, Files, Record Keeping, Group Certificates, Liability FBT, Bookkeeping Software, Billing System, FBT Calculations, Superannuation, PAG Bills, Taxation Duties and also my staff taxation needs are in safe and capable hands with reportable benefits.

I also wanted to personally mention just how I appreciate Susan being part of our company while we grew with all of our ups and downs from a little shop of 20 staff to 4 establishments with 350 staff!

This incredible woman was able to adjust and alter her style to the needs of my alternatively complex business needs – seamlessly and accordingly!!!
